前言
今天复习一下springmvc+hibernate的搭建，本来想着将spring-security权限控制框架也映入其中的，但是发现内容太多了，spring-security的就留在下一篇吧，这篇主要搭建springmvc4.1.4和hibernate4.3.8，之前也打了好多springmvc的，这部分已经非常的熟悉了，毕竟业开发过一年多springmvc的，这次持久层采用hibernate，数据源采用c3p0，数据库暂采用mysql，主要是想复习一下hibernate。搭建springmvc+hibernate的框架的思路如下：
1、设计数据库：设计好表结构，最好符合3nf，采用hibernate tools将设计好的表自动生成对应的实体entity。
1、创建maven项目，按需映入maven包依赖。
2、搭建spring：配置spring对控件层bean的注入。
3、搭建hibernate：配置数据源，配置sessionfactory，配置事务，以及二级缓存ehcache的配置。
4、测试spring+hibernate的框架搭建，写单元测试junit，测试事务配置等。
5、映入springmvc：配置springmvc配置信息。
6、配置web.xml容器
7、测试三个框架的整合：maven编译打包部署服务器，测试。
1、数据库设计
设计一个权限、角色、用户的表。自然如果一个用户可以有多个角色，一个角色多个用户所拥有；一个角色拥有多个权限，一个权限对应多个角色。所以按照数据库表结构设计，符合3nf的话我们需要5张表进行存在。表的具体信息就不列出了（可以下在源码，里面还有数据库），表关系如下：
这里面id才用到是java的uuid（36位）
2、创建maven项目，编写pom.xml文件
创建一个maven的webapp项目，编写pom.xml文件，引入所需的包依赖，我这里就将所需的全部的映入了。
pom.xml文件内容如下:
我要评论

3、引入spring配置
编写配置文件，配置文件放在src/main/resources资源目录下（下同）。
项目所需的配置信息config.properties
#application configs #jdbc c3p0 config jdbc.driver = com.mysql.jdbc.driver jdbc.url = jdbc:mysql://localhost:3306/work?useunicode=true&characterencoding=utf-8 jdbc.username = root jdbc.password = 12345 #hibernate config hibernate.dialect = org.hibernate.dialect.mysqldialect hibernate.show_sql = true hibernate.format_sql = false hibernate.hbm2ddl.auto = update hibernate.cache.use_second_level_cache = true hibernate.cache.use_query_cache = true hibernate.cache.region.factory_class = org.hibernate.cache.ehcache.ehcacheregionfactory hibernate.cache.provider_configuration_file_resource_path = ehcache.xml
3.1、spring配置
spring.xml的配置文件如下：
<?xml version="1.0" encoding="utf-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xmlns:context="http://www.springframework.org/schema/context" xsi:schemalocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd"> <!-- 加载配置文件 --> <context:property-placeholder location="classpath:config.properties"/> <!-- 扫描service自动注入为bean --> <context:component-scan base-package="org.andy.work.service.impl,org.andy.work.dao.impl" /> </beans>
上面spring配置了对应包下组件bean自动注入管理，我们需要将dao,service的实现类交由spring管理，如（@repository，@service）。
3.2、引入日志文件配置log4j
log4j.properties的配置文件如下：
### set log levels ###
log4j.rootlogger = info , c , d , e
### console ###
log4j.appender.c = org.apache.log4j.consoleappender
log4j.appender.c.target = system.out
log4j.appender.c.layout = org.apache.log4j.patternlayout
log4j.appender.c.layout.conversionpattern = [springmvc_hibernate_demo][%p] [%-d{yyyy-mm-dd hh:mm:ss}] %c.%m(%l) | %m%n
### log file ###
log4j.appender.d = org.apache.log4j.dailyrollingfileappender
log4j.appender.d.file = ../logs/springmvc_hibernate_demo.log
log4j.appender.d.append = true
log4j.appender.d.threshold = info
log4j.appender.d.layout = org.apache.log4j.patternlayout
log4j.appender.d.layout.conversionpattern = [springmvc_hibernate_demo][%p] [%-d{yyyy-mm-dd hh:mm:ss}] %c.%m(%l) | %m%n
### exception ###
log4j.appender.e = org.apache.log4j.dailyrollingfileappender
log4j.appender.e.file = ../logs/springmvc_hibernate_demo_error.log
log4j.appender.e.append = true
log4j.appender.e.threshold = error
log4j.appender.e.layout = org.apache.log4j.patternlayout
log4j.appender.e.layout.conversionpattern = [sspringmvc_hibernate_demo][%p] [%-d{yyyy-mm-dd hh:mm:ss}] %c.%m(%l) | %m%n
4、hibernate配置
hibernate的配置主要包括：配置数据源c3p0，配置sessionfactory，配置事务管理器，配置事务管理，其spring-hibernate.xml文件如下：
<?xml version="1.0" encoding="utf-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:aop="http://www.springframework.org/schema/aop"
xsi:schemalocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-4.1.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-4.1.xsd

<property name="user" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
<!-- 请求超时时间 -->
<property name="checkouttimeout" value="30000" />
<!-- 每60秒检查所有连接池中的空闲连接。默认值: 0，不检查 -->
<property name="idleconnectiontestperiod" value="30" />
<!-- 连接数据库连接池最大空闲时间 -->

<property name="maxpoolsize" value="20" />
<!--当连接池中的连接耗尽的时候c3p0一次同时获取的连接数。默认值: 3 -->
<property name="acquireincrement" value="5" />
</bean>
<!-- 配置hibernate的sessionfactory -->
<bean id="sessionfactory"
class="org.springframework.orm.hibernate4.localsessionfactorybean">
<!-- 注入数据源 相关信息看源码 -->
<property name="datasource" ref="datasource" />
<!-- hibernate配置信息 -->
<property name="hibernateproperties">
<props>
<prop key="hibernate.dialect">${hibernate.dialect}</prop>

</prop>
</props>
</property>
<!-- 扫描hibernate注解配置的entity -->
<property name="packagestoscan" value="org.andy.work.entity" />
</bean>
<!-- 配置事务管理器 -->
<bean id="transactionmanager"
class="org.springframework.orm.hibernate4.hibernatetransactionmanager">
<property name="sessionfactory" ref="sessionfactory" />
</bean>
<!-- 配置事务增强处理bean，指定事务管理器 -->
<tx:advice id="transactionadvice" transaction-manager="transactionmanager">
<!-- 配置详细事务处理语义 -->
<tx:attributes>
<tx:method name="insert*" propagation="required" />
<tx:method name="update*" propagation="required" />
<tx:method name="delete*" propagation="required" />
<tx:method name="get*" propagation="supports" read-only="true" />
<tx:method name="find*" propagation="supports" read-only="true" />
<tx:method name="select*" propagation="supports" read-only="true" />
<tx:method name="load*" propagation="supports" read-only="true" />
<!-- 其他采用默认事务方式 -->
<tx:method name="*" />
</tx:attributes>
</tx:advice>
<!-- spring aop事务管理 -->
<aop:config>
<!-- 配置切入点 -->
<aop:pointcut id="transactionpointcut"
expression="execution(* org.andy.work.service..*impl.*(..))" />
<!-- 指定在txadvice切入点应用txadvice事务增强处理 -->
<aop:advisor pointcut-ref="transactionpointcut"
advice-ref="transactionadvice" />
</aop:config>
</beans>
上面配置了二级缓存，ehcache，相关的具体信息查看上一篇hibernate二级缓存以及ehcache的搭建配置，下面是二级缓存的配置。
4.1、ehcache.xml的配置
<?xml version="1.0" encoding="utf-8"?> <ehcache xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xsi:nonamespaceschemalocation="../config/ehcache.xsd"> <diskstore path="d:/ehcache" /> <!-- defaultcache setting. --> <defaultcache maxelementsinmemory="1000" eternal="false" timetoidleseconds="120" timetoliveseconds="120" maxelementsondisk="1000000" overflowtodisk="true" memorystoreevictionpolicy="lru"> </defaultcache> <!-- special objects setting. --> <cache name="org.andy.work.entity.acctuser" maxelementsinmemory="2" memorystoreevictionpolicy="lru" eternal="true" diskpersistent="false" overflowtodisk="false" maxelementsondisk="1000000" /> </ehcache>
上面hibernate二级缓存ehcache存放磁盘是d:/ehcache
5、生成业务entity实体
设计好数据表后，hibernate的实体有工具hibernate tools自动生成，eclipse需要安装hibernate tools插件（我在线安装过几次都不成功，推荐使用links离线安装，附录将介绍），所以不需要手工的书写，下面就贴一个用户信息的实体，acctuser.java
package org.andy.work.entity;
// generated 2015-2-3 10:43:00 by hibernate tools 4.0.0
import java.util.date;
import java.util.hashset;
import java.util.set;
import javax.persistence.column;
import javax.persistence.entity;
import javax.persistence.fetchtype;
import javax.persistence.id;
import javax.persistence.joincolumn;
import javax.persistence.jointable;
import javax.persistence.manytomany;
import javax.persistence.table;
import javax.persistence.temporal;
import javax.persistence.temporaltype;
import org.hibernate.annotations.cache;
import org.hibernate.annotations.cacheconcurrencystrategy;
import com.fasterxml.jackson.annotation.jsonignoreproperties;
/**
* acctuser generated by hbm2java
*/
@entity
@table(name = "acct_user", catalog = "work")
@cache(usage = cacheconcurrencystrategy.read_write)
public class acctuser implements java.io.serializable {
/**
*
*/
private static final long serialversionuid = 6980093847795726310l;
private string id;
private string nickname;
private string telephone;
private date registertime;
private set<acctrole> acctroles = new hashset<acctrole>(0);
public acctuser() {
}
public acctuser(string id, string nickname) {
this.id = id;
this.nickname = nickname;
}
public acctuser(string id, string nickname, string telephone,
date registertime, set<acctrole> acctroles) {
this.id = id;
this.nickname = nickname;
this.telephone = telephone;
this.registertime = registertime;
this.acctroles = acctroles;
}
@id
@column(name = "id", unique = true, nullable = false, length = 36)
public string getid() {
return this.id;
}
public void setid(string id) {
this.id = id;
}
@column(name = "nick_name", nullable = false)
public string getnickname() {
return this.nickname;
}
public void setnickname(string nickname) {
this.nickname = nickname;
}
@column(name = "telephone")
public string gettelephone() {
return this.telephone;
}
public void settelephone(string telephone) {
this.telephone = telephone;
}
@temporal(temporaltype.timestamp)
@column(name = "register_time", length = 19)
public date getregistertime() {
return this.registertime;
}
public void setregistertime(date registertime) {
this.registertime = registertime;
}
@jsonignoreproperties(value={"acctusers", "acctauthorities"})
@manytomany(fetch = fetchtype.lazy)
@cache(usage = cacheconcurrencystrategy.read_write)
@jointable(name = "acct_user_role", catalog = "work", joincolumns = { @joincolumn(name = "user_id", nullable = false, updatable = false) }, inversejoincolumns = { @joincolumn(name = "role_id", nullable = false, updatable = false) })
public set<acctrole> getacctroles() {
return this.acctroles;
}
public void setacctroles(set<acctrole> acctroles) {
this.acctroles = acctroles;
}
}
上面有几个需要注意的：
上面大多数都是hibernate tools自动生成的，但是有几个需要手动添加：
1、如果这个实体使用二级缓存的话，需要添加@cache注解；
2、如果该实体里面还有集合元素（set， map，list），如果实体要采用二级缓存，那么这些集合元素必须也添加@cache注解。
3、@jsonignoreproperties注解是为了防止springmvc在json返回时产生循环输出使用，如果不配置的话就会出现json死循环（还有多对多，一对多的属性时）。
4、@jsonignore这个是在转换成json是忽略该属性，而@jsonignoreproperties(value={"acctusers", "acctauthorities"})则是忽略acctroles里面的acctusers和acctauthorites属性。
6、创建dao层
6.1dao接口
dao层和service层我们肯定采用的是面相接口编程的思想，所以，我们先定义一个通用的dao接口，genericdao.java
package org.andy.work.dao;
import java.io.serializable;
import java.util.list;
/**
* 创建时间：2015-2-6 下午2:26:42
*
* @author andy
* @version 2.2
*
* dao通用接口
*/
interface genericdao<t, pk extends serializable> {
t load(pk id);
t get(pk id);
list<t> findall();
void persist(t entity);
pk save(t entity);
void saveorupdate(t entity);
void delete(pk id);
void flush();
}
在定义具体的userdao.java接口
package org.andy.work.dao;
import org.andy.work.entity.acctuser;
/**
* 创建时间：2015-2-6 下午2:43:50
*
* @author andy
* @version 2.2
*
* 用户dao接口
*/
public interface userdao extends genericdao<acctuser, string> {
}
6.2、dao层实现类
我们需要将dao层的实现类注入为bean，所以需要添加@repository注解，userdaoimpl如下：
package org.andy.work.dao.impl;
import java.util.list;
import org.andy.work.dao.userdao;
import org.andy.work.entity.acctuser;
import org.hibernate.session;
import org.hibernate.sessionfactory;
import org.springframework.beans.factory.annotation.autowired;
import org.springframework.stereotype.repository;
/**
* 创建时间：2015-2-6 下午2:45:14
*
* @author andy
* @version 2.2
*/
@repository("userdao")
public class userdaoimpl implements userdao {
@autowired
private sessionfactory sessionfactory;
private session getcurrentsession() {
return this.sessionfactory.getcurrentsession();
}
@override
public acctuser load(string id) {
return (acctuser) this.getcurrentsession().load(acctuser.class, id);
}
@override
public acctuser get(string id) {
return (acctuser) this.getcurrentsession().get(acctuser.class, id);
}
@suppresswarnings("unchecked")
@override
public list<acctuser> findall() {
list<acctuser> acctusers = this.getcurrentsession().createquery("from acctuser").setcacheable(true).list();
return acctusers;
}
@override
public void persist(acctuser entity) {
this.getcurrentsession().persist(entity);
}
@override
public string save(acctuser entity) {
return (string) this.getcurrentsession().save(entity);
}
@override
public void saveorupdate(acctuser entity) {
this.getcurrentsession().saveorupdate(entity);
}
@override
public void delete(string id) {
acctuser entity = this.load(id);
this.getcurrentsession().delete(entity);
}
@override
public void flush() {
this.getcurrentsession().flush();
}
}
7、创建service层
7.1、service层接口
package org.andy.work.service;
import java.util.list;
import org.andy.work.entity.acctuser;
/**
* 创建时间：2015-2-6 下午3:18:57
*
* @author andy
* @version 2.2
* userservice接口
*/
public interface userservice {
acctuser load(string id);
acctuser get(string id);
list<acctuser> findall();
void persist(acctuser entity);
string save(acctuser entity);
void saveorupdate(acctuser entity);
void delete(string id);
void flush();
}
7.2、service层实现类
userserviceimpl就需要注入上面定义的dao层bean。
package org.andy.work.service.impl;
import java.util.list;
import org.andy.work.dao.userdao;
import org.andy.work.entity.acctuser;
import org.andy.work.service.userservice;
import org.springframework.beans.factory.annotation.autowired;
import org.springframework.stereotype.service;
/**
* 创建时间：2015-2-6 下午3:24:16
*
* @author andy
* @version 2.2 userservice 的实现
*/
@service("userservice")
public class userserviceimpl implements userservice {
@autowired
private userdao userdao;
@override
public acctuser load(string id) {
return userdao.load(id);
}
@override
public acctuser get(string id) {
return userdao.get(id);
}
@override
public list<acctuser> findall() {
return userdao.findall();
}
@override
public void persist(acctuser entity) {
userdao.persist(entity);
}
@override
public string save(acctuser entity) {
return userdao.save(entity);
}
@override
public void saveorupdate(acctuser entity) {
userdao.saveorupdate(entity);
}
@override
public void delete(string id) {
userdao.delete(id);
}
@override
public void flush() {
userdao.flush();
}
}
8、测试spring和hibernate的整合
我们可以在src/test/java编写测试类，测试上面的配置，如果测试成功已经基本大功告成。
package org.andy.work.service;
import java.util.date;
import java.util.list;
import java.util.uuid;
import org.andy.work.entity.acctuser;
import org.apache.log4j.logger;
import org.junit.test;
import org.junit.runner.runwith;
import org.springframework.beans.factory.annotation.autowired;
import org.springframework.test.context.contextconfiguration;
import org.springframework.test.context.junit4.springjunit4classrunner;
import com.alibaba.fastjson.json;
/**
* 创建时间：2015-2-6 下午3:31:07
*
* @author andy
* @version 2.2
*/
@runwith(springjunit4classrunner.class)
@contextconfiguration(locations = { "classpath:spring.xml",
"classpath:spring-hibernate.xml" })
public class testuserservice {
private static final logger logger = logger
.getlogger(testuserservice.class);
@autowired
private userservice userservice;
@test
public void save() {
acctuser acctuser = new acctuser();
acctuser.setid(uuid.randomuuid().tostring());
acctuser.setnickname("andy");
acctuser.setregistertime(new date());
acctuser.settelephone("13022221111");
string id = userservice.save(acctuser);
logger.info(json.tojsonstring(id));
}
}
9、引入springmvc
添加spring-mvc.xml文件
<?xml version="1.0" encoding="utf-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xsi:schemalocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd"> <!-- 自动扫描@controller注入为bean --> <context:component-scan base-package="org.andy.work.controller" /> <!-- 以下为springmvc配置 --> <mvc:annotation-driven> <!-- 返回json数据，@response使用 --> <mvc:message-converters register-defaults="true"> <bean class="org.springframework.http.converter.json.mappingjackson2httpmessageconverter"> <property name="supportedmediatypes"> <list> <value>text/html;charset=utf-8</value> <value>application/json;charset=utf-8</value> </list> </property> </bean> </mvc:message-converters> </mvc:annotation-driven> <!-- 对模型视图名称的解析，即在模型视图名称添加前后缀 --> <bean class="org.springframework.web.servlet.view.internalresourceviewresolver"> <property name="viewclass" value="org.springframework.web.servlet.view.jstlview" /> <property name="prefix" value="/web-inf/views" /> <property name="suffix" value=".jsp" /> </bean> </beans>
上面配置了包扫描controller，[email protected]��，和视图层的配置。
10、配置web.xml容器
web容器是web项目的大脑，所以web容器，首先需要引入spring，让spring管理各个框架，并将其注入为bean。然后配置控制层的filter信息。并且配置了springmvc拦截的url为以.hmls结尾的请求。
web.xml文件如下：
<?xml version="1.0" encoding="utf-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemalocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="webapp_id" version="2.5"> <display-name>springmvc_demo</display-name> <context-param> <param-name>contextconfiglocation</param-name> <param-value>classpath:spring.xml,classpath:spring-hibernate.xml</param-value> </context-param> <filter> <filter-name>encodingfilter</filter-name> <filter-class>org.springframework.web.filter.characterencodingfilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>utf-8</param-value> </init-param> <init-param> <param-name>forceencoding</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>encodingfilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- opensessioninview配置 作用是延迟session关闭到view层 --> <filter> <filter-name>opensessioninviewfilter</filter-name> <filter-class>org.springframework.orm.hibernate4.support.opensessioninviewfilter</filter-class> <init-param> <param-name>singlesession</param-name> <param-value>true</param-value> </init-param> </filter> <!-- 监听servletcontext，启动contextconfiglocation中的spring配置信息 --> <listener> <listener-class>org.springframework.web.context.contextloaderlistener</listener-class> </listener> <!-- 防止spring内存溢出监听器 --> <listener> <listener-class>org.springframework.web.util.introspectorcleanuplistener</listener-class> </listener> <servlet> <description>spring mvc servlet</description> <servlet-name>rest</servlet-name> <servlet-class>org.springframework.web.servlet.dispatcherservlet</servlet-class> <init-param> <param-name>contextconfiglocation</param-name> <!-- 此处配置的是springmvc的配置文件 --> <param-value>classpath:spring-mvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>rest</servlet-name> <url-pattern>*.htmls</url-pattern> </servlet-mapping> <filter-mapping> <filter-name>opensessioninviewfilter</filter-name> <url-pattern>*.htmls</url-pattern> </filter-mapping> <!-- 配置session超时时间，单位分钟 --> <session-config> <session-timeout>30</session-timeout> </session-config> <welcome-file-list> <welcome-file>/index.jsp</welcome-file> </welcome-file-list> </web-app>
11、创建控制层controller
控制层usercontroller
package org.andy.work.controller;
import java.util.list;
import org.andy.work.entity.acctuser;
import org.andy.work.service.userservice;
import org.apache.log4j.logger;
import org.springframework.beans.factory.annotation.autowired;
import org.springframework.stereotype.controller;
import org.springframework.ui.modelmap;
import org.springframework.web.bind.annotation.pathvariable;
import org.springframework.web.bind.annotation.requestmapping;
import org.springframework.web.bind.annotation.responsebody;
/**
* 创建时间：2015-2-7 上午11:49:00
* @author andy
* @version 2.2
* 描述： 用户controller
*/
@controller
@requestmapping("/user")
public class usercontroller {
private static final logger logger = logger.getlogger(usercontroller.class);
@autowired
private userservice userservice;
@requestmapping("/showinfo/{userid}")
public string showuserinfo(modelmap modelmap, @pathvariable string userid){
logger.info("查询用户：" + userid);
acctuser userinfo = userservice.load(userid);
modelmap.addattribute("userinfo", userinfo);
return "/user/showinfo";
}
@requestmapping("/showinfos")
public @responsebody list<acctuser> showuserinfos(){
logger.info("查询用户全部用户");
list<acctuser> userinfos = userservice.findall();
return userinfos;
}
}
12、创建视图层
在src/main/webapp/web-inf/views下 创建user/showinfo.jsp
<%@ page language="java" contenttype="text/html; charset=utf-8" pageencoding="utf-8"%>
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%@taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt"%>
<%
string path = request.getcontextpath();
string basepath = request.getscheme() + "://"
+ request.getservername() + ":" + request.getserverport()
+ path + "/";
%>
<!doctype html public "-//w3c//dtd html 4.01 transitional//en" "http://www.w3.org/tr/html4/loose.dtd">
<html>
<head>
<base href="<%=basepath%>" />
<meta http-equiv="content-type" content="text/html; charset=utf-8">
<script type="text/javascript" src="js/jquery-1.9.1.min.js"></script>
<title>userinfo</title>
</head>
<body>
用户信息 昵称： ${userinfo.nickname} 用户id：${userinfo.id} 用户电话:${userinfo.telephone } 注册时间：
<fmt:formatdate value="${userinfo.registertime }" pattern="yyyy-mm-dd hh:mm:ss" />
角色：[
<c:foreach items="${ userinfo.acctroles}" var="role">
${role.name } 权限[
<c:foreach items="${ role.acctauthorities}" var="authority">
${authority.name }
</c:foreach> ]
</c:foreach>
]
<br /> ajax显示全部用户信息：
<div id="show_all_user"></div>
</body>
<script type="text/javascript">
$.ajax({
type : "get",
url : "user/showinfos.htmls",
datatype : "json",
success : function(data) {
$(data).each(
function(i, user) {
var p = "<p>昵称:" + user.nickname + " 电话:"
+ user.telephone + " 注册时间:"
+ user.registertime + " id:" + user.id +
"</p>";
$("#show_all_user").append(p);
});
},
async : true
});
</script>
</html>
13、部署服务器测试
使用maven打包部署：clean compile package
部署到tomcat，测试
主要测试上面的 http://localhost:8080/springmvc_hibernate_demo/user/showinfo/6e5afb1d-50e1-45fe-b6fe-b9e399415387.htmls
和http://localhost:8080/springmvc_hibernate_demo/user/showinfos.htmls （json数据返回）
上面视图层就包含了这两条url请求的测试：
ok，到此spring+springmvc+hibernate搭建完毕。
