IDEA中Mybatis的MGB使用逆向工程配置的详细教程

添加依赖
添加generatorconfig.xml文件
在maven的plugins中运行mybatis-generator插件
注意事项：
(1).generatorconfig.xml文件需要放在resource路径下。

================================================

1、添加依赖

<dependencies>
  <dependency>
   <groupid>org.mybatis</groupid>
   <artifactid>mybatis</artifactid>
   <version>3.2.8</version>
  </dependency>
 </dependencies>
 <!-- 控制 maven 在构建过程中相关配置 -->
 <build>
  <!-- 构建过程中用到的插件 -->
  <plugins>
   <!-- 具体插件，逆向工程的操作是以构建过程中插件形式出现的 -->
   <plugin>
    <groupid>org.mybatis.generator</groupid>
    <artifactid>mybatis-generator-maven-plugin</artifactid>
    <version>1.3.0</version>
    <!-- 插件的依赖 -->
    <dependencies>
     <!-- 逆向工程的核心依赖 -->
     <dependency>
      <groupid>org.mybatis.generator</groupid>
      <artifactid>mybatis-generator-core</artifactid>
      <version>1.3.2</version>
     </dependency>
     <!-- 数据库连接池 -->
     <dependency>
      <groupid>com.mchange</groupid>
      <artifactid>c3p0</artifactid>
      <version>0.9.2</version>
     </dependency>
     <!-- mysql 驱动 -->
     <dependency>
      <groupid>mysql</groupid>
      <artifactid>mysql-connector-java</artifactid>
      <version>5.1.8</version>
     </dependency>
    </dependencies>
   </plugin>
  </plugins>
 </build>

2、添加generatorconfig.xml文件

<?xml version="1.0" encoding="utf-8"?>
<!doctype generatorconfiguration
  public "-//mybatis.org//dtd mybatis generator configuration 1.0//en"
  "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">

<generatorconfiguration>


	<commentgenerator>
	 <!-- 关闭自动生成的注释 -->
	 <property name="suppressallcomments" value="true" />
	</commentgenerator>
	
 <context id="db2tables" targetruntime="mybatis3">
  <!--1.连接数据库-->
  <jdbcconnection
    driverclass="com.mysql.jdbc.driver"
    connectionurl="jdbc:mysql://localhost:3306/project_crowd"
    userid="root"
    password="root">
  </jdbcconnection>


  <javatyperesolver >
   <property name="forcebigdecimals" value="false" />
  </javatyperesolver>

  <javamodelgenerator targetpackage="com.it.bean" targetproject="src/main/java">
   <property name="enablesubpackages" value="true" />
   <property name="trimstrings" value="true" />
  </javamodelgenerator>

  <sqlmapgenerator targetpackage="com.it.dao" targetproject="src/main/java">
   <property name="enablesubpackages" value="true" />
  </sqlmapgenerator>

  <javaclientgenerator type="xmlmapper" targetpackage="com.it.dao" targetproject="src/main/java">
   <property name="enablesubpackages" value="true" />
  </javaclientgenerator>

  <table tablename="t_admin" domainobjectname="admin" > </table>

 </context>
</generatorconfiguration>

3.在maven的plugins中运行mybatis-generator插件
