mybatis反向工程

首先创建一个test类：

在main方法里写上如下代码：

List <String> warnings = new ArrayList <String>();
boolean overwrite = true;
File configFile = new File("generator.xml");
ConfigurationParser cp = new ConfigurationParser(warnings);
Configuration config = cp.parseConfiguration(configFile);
DefaultShellCallback callback = new DefaultShellCallback(overwrite);
MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config,callback,warnings);
myBatisGenerator.generate(null);

在工程目录下新建一个generator.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>

   <context id="DB2Tables" targetRuntime="MyBatis3">
   
   <commentGenerator>
     <property name="suppressAllComments" value="true"></property>   
   </commentGenerator>
  
  
    <!-- 设定数据库连接 -->
    <jdbcConnection driverClass="com.mysql.jdbc.Driver"
        connectionURL="jdbc:mysql://localhost:3306/mybatis"
        userId="root"
        password="123">
    </jdbcConnection>

    <javaTypeResolver >
      <property name="forceBigDecimals" value="false" />
    </javaTypeResolver>

    <!--  生成 bean 存放的位置  -->
    <javaModelGenerator targetPackage="com.ujiuye.bean" targetProject=".\src">
      <property name="enableSubPackages" value="true" />
      <property name="trimStrings" value="true" />
    </javaModelGenerator>

    <!-- 生成的mapper文件的位置 -->
    <sqlMapGenerator targetPackage="com.ujiuye.mapper"  targetProject=".\src">
      <property name="enableSubPackages" value="true" />
    </sqlMapGenerator>

    <!-- 生成的mapper.xml 对应的那个mapper接口的存放位置  -->
    <javaClientGenerator type="XMLMAPPER" targetPackage="com.ujiuye.mapper"  targetProject=".\src">
      <property name="enableSubPackages" value="true" />
    </javaClientGenerator>

    <!-- 设定反向生成的表 -->
    <table tableName="Person"></table>
    <table tableName="car"></table>
    <table tableName="card"></table>

  </context>
</generatorConfiguration>
