前面一篇有说道如何在myeclipse中搭建maven项目，这里将继续介绍如何在搭建好的基础maven项目中引入我们常用的javaweb框架——springmvc！
①在建立好的maven项目中的pom.xml文件引入依赖，代码如下：
<project xmlns="http://maven.apache.org/pom/4.0.0" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xsi:schemalocation="http://maven.apache.org/pom/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelversion>4.0.0</modelversion> <groupid>wechat.cuiyongzhi.com</groupid> <artifactid>wechat</artifactid> <packaging>war</packaging> <version>0.0.1-snapshot</version> <name>wechat</name> <url>http://maven.apache.org</url> <dependencies> <!-- spring --> <dependency> <groupid>org.springframework</groupid> <artifactid>spring-test</artifactid> <version>3.2.0.release</version> </dependency> <dependency> <groupid>org.springframework</groupid> <artifactid>spring-webmvc</artifactid> <version>3.2.0.release</version> </dependency> <dependency> <groupid>org.springframework</groupid> <artifactid>spring-core</artifactid> <version>3.2.0.release</version> </dependency> <!-- mybatis --> <dependency> <groupid>org.mybatis</groupid> <artifactid>mybatis</artifactid> <version>3.1.1</version> </dependency> <dependency> <groupid>org.mybatis</groupid> <artifactid>mybatis-spring</artifactid> <version>1.1.1</version> </dependency> <!-- mysql --> <dependency> <groupid>mysql</groupid> <artifactid>mysql-connector-java</artifactid> <version>5.1.21</version> </dependency> <!-- junit测试 --> <dependency> <groupid>junit</groupid> <artifactid>junit</artifactid> <version>4.11</version> <scope>test</scope> </dependency> <!-- mysql阿里连接池druid --> <dependency> <groupid>com.alibaba</groupid> <artifactid>druid</artifactid> <version>0.2.9</version> </dependency> <!-- spring aop包 --> <dependency> <groupid>org.aspectj</groupid> <artifactid>aspectjweaver</artifactid> <version>1.7.1</version> </dependency> <!-- json包 --> <dependency> <groupid>com.alibaba</groupid> <artifactid>fastjson</artifactid> <version>1.2.7</version> </dependency> <!-- 文件上传包 --> <dependency> <groupid>commons-fileupload</groupid> <artifactid>commons-fileupload</artifactid> <version>1.2.2</version> </dependency> <!--servlet包 --> <dependency> <groupid>javax.servlet</groupid> <artifactid>servlet-api</artifactid> <version>3.0-alpha-1</version> </dependency> <dependency> <groupid>javax.servlet.jsp</groupid> <artifactid>jsp-api</artifactid> <version>2.1</version> <scope>provided</scope> </dependency> <dependency> <groupid>javax.servlet</groupid> <artifactid>jstl</artifactid> <version>1.2</version> </dependency> <!-- 日志包 --> <dependency> <groupid>log4j</groupid> <artifactid>log4j</artifactid> <version>1.2.17</version> </dependency> </dependencies> <build> <finalname>wechat</finalname> </build> </project>
②修改项目路径下的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:web="http://java.sun.com/xml/ns/javaee" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemalocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd http://www.springframework.org/schema/websocket http://www.springframework.org/schema/websocket/spring-websocket.xsd" id="webapp_id" version="3.0"> <display-name>com.cuiyongzhi.wechat</display-name> <context-param> <param-name>contextconfiglocation</param-name> <param-value>classpath:spring.xml,classpath:spring-mybatis.xml</param-value> <!-- ,classpath:spring-quartz.xml 用于做任务调度 任务定时都可以 --> </context-param> <context-param> <param-name>log4jconfiglocation</param-name> <param-value>classpath:log4j.properties</param-value> </context-param> <listener> <listener-class>org.springframework.web.util.log4jconfiglistener</listener-class> </listener> <context-param> <param-name>spring.profiles.active</param-name> <param-value>dev</param-value> </context-param> <context-param> <param-name>spring.profiles.default</param-name> <param-value>dev</param-value> </context-param> <context-param> <param-name>spring.livebeansview.mbeandomain</param-name> <param-value>dev</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> <listener> <description>spring监听器</description> <listener-class>org.springframework.web.context.contextloaderlistener</listener-class> </listener> <!-- 防止内存溢出 --> <listener> <listener-class>org.springframework.web.util.introspectorcleanuplistener</listener-class> </listener> <servlet> <description>spring mvc servlet</description> <servlet-name>springmvc</servlet-name> <servlet-class>org.springframework.web.servlet.dispatcherservlet</servlet-class> <init-param> <description>spring mvc 配置文件</description> <param-name>contextconfiglocation</param-name> <param-value>classpath:spring-mvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet> <servlet-name>interface_url-init_servlet</servlet-name> <servlet-class>com.cuiyongzhi.web.start.interfaceurlintiservlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>springmvc</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>/index.jsp</welcome-file> </welcome-file-list> <session-config> <session-timeout>300</session-timeout> </session-config> <error-page> <error-code>404</error-code> <location>/web-inf/error/error.jsp</location> </error-page> <error-page> <error-code>500</error-code> <location>/web-inf/error/error.jsp</location> </error-page> <servlet-mapping> <servlet-name>default</servlet-name> <url-pattern>*.css</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>default</servlet-name> <url-pattern>*.gif</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>default</servlet-name> <url-pattern>*.jpg</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>default</servlet-name> <url-pattern>*.js</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>default</servlet-name> <url-pattern>*.xhtml</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>default</servlet-name> <url-pattern>*.html</url-pattern> </servlet-mapping> <filter> <filter-name>druidwebstatfilter</filter-name> <filter-class>com.alibaba.druid.support.http.webstatfilter</filter-class> <init-param> <param-name>exclusions</param-name> <param-value>*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*</param-value> </init-param> </filter> <filter-mapping> <filter-name>druidwebstatfilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <servlet> <servlet-name>druidstatview</servlet-name> <servlet-class>com.alibaba.druid.support.http.statviewservlet</servlet-class> <init-param> <!-- 允许清空统计数据 --> <param-name>resetenable</param-name> <param-value>true</param-value> </init-param> <init-param> <!-- 用户名 --> <param-name>loginusername</param-name> <param-value>cuiyongzhi</param-value> </init-param> <init-param> <!-- 密码 --> <param-name>loginpassword</param-name> <param-value>123456</param-value> </init-param> </servlet> <servlet-mapping> <servlet-name>druidstatview</servlet-name> <url-pattern>/druid/*</url-pattern> </servlet-mapping> <!-- 访问监控页面：http://ip：port/projectname/druid/ --> <jsp-config> <jsp-property-group> <display-name>jspconfiguration</display-name> <url-pattern>*.jsp</url-pattern> <el-ignored>false</el-ignored> <scripting-invalid>false</scripting-invalid> <include-prelude>/web-inf/common/head.jsp</include-prelude> </jsp-property-group> </jsp-config> </web-app>
③添加数据库配置信息，这里项目配置的数据库为mysql，在 resources下新建config.properties配置文件，设置如下：
validationquery=select 1 jdbc_url=jdbc:mysql://127.0.0.1:3306/wechat?useunicode=true&characterencoding=utf-8&zerodatetimebehavior=converttonull jdbc_username=root jdbc_password=123456789
④在 resources下新建spring.xml配置文件，设置如下：
<?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-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"> <!-- 引入属性文件 --> <context:property-placeholder location="classpath:config.properties" /> <!-- 自动扫描(自动注入) --> <context:component-scan base-package="com.cuiyongzhi.web.service" /> <context:component-scan base-package="com.cuiyongzhi.wechat.*" /> </beans>
⑤在 resources下新建spring-mvc.xml配置文件，设置如下：
我要评论

⑥在 resources下新建spring-mybatis.xml配置文件，设置如下：

⑦在 resources下新建log4j.properties配置文件，用于日志的输出等级以及输出位置设置，设置如下：
到这里springmvc+mybatis的基本配置文件基本就完成了，大致的项目结构如下：
