IDEA中Mybatis的MGB使用逆向工程配置的详细教程

1. 添加依赖
2. 添加generatorConfig.xml文件
3. 在maven的plugins中运行mybatis-generator插件
4. 注意事项：
5. (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
