MyBatis Generator配置使用

MyBatis Generator 是MyBatis提供生成代碼的工具，用於生成entity、Mapper、Mapper.xml
所需jar包：mybatis-generator-core-1.3.5.jar

XML配置

<?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>
  <context id="Mysql" targetRuntime="MyBatis3Simple" defaultModelType="flat">

    <plugin type="tk.mybatis.mapper.generator.MapperPlugin">
      <property name="mappers" value="tk.mybatis.mapper.common.Mapper"/>
      <!-- caseSensitive默認false，當數據庫表名區分大小寫時，能夠將該屬性設置爲true -->
      <property name="caseSensitive" value="true"/>
    </plugin>

    <jdbcConnection driverClass="com.mysql.jdbc.Driver"
                    connectionURL="jdbc:mysql://localhost:3306/gsinspector"
                    userId="root"
                    password="root">
    </jdbcConnection>

    <!-- 生成實體類 -->
    <javaModelGenerator targetPackage="com.yupont.gs.model" targetProject="d:\1"/>
    
    <!-- 生成mapper對應的xml文件，可選生成 -->
    <sqlMapGenerator targetPackage="com.yupont.gs.dao.mapper"  targetProject="d:\2"/>

    <!-- 生成mapper -->
    <javaClientGenerator targetPackage="com.yupont.gs.dao.mapper" targetProject="d:\3" type="XMLMAPPER" />

    <!-- 指定%全部表包含一個都有一個id自增的主鍵 -->
    <!-- <table tableName="%" >
      <generatedKey column="id" sqlStatement="Mysql" identity="true"/>
    </table> -->
    
    <!--對應數據庫表Test1，指定生成的名字爲Test，例如TestMapper.java,Test.java,Test,TestMapper.xml-->
    <table tableName="Test1" domainObjectName="Test" >
    </table>
  </context>
</generatorConfiguration>
