maven代码

配置步骤：

1.先配置好配置文件，MBG.xml

<?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">    <!-- 注解配置 --><commentGenerator>  <property name="suppressAllComments" value="true" /></commentGenerator>  <!-- JDBC配置 -->    <jdbcConnection driverClass="com.mysql.jdbc.Driver"        connectionURL="jdbc:mysql://localhost:3306/ssm"        userId="root"        password="">    </jdbcConnection>    <javaTypeResolver >      <property name="forceBigDecimals" value="false" />    </javaTypeResolver><!-- 逆向工程生成位置 -->    <javaModelGenerator targetPackage="bean" targetProject=".\src\main\java">      <property name="enableSubPackages" value="true" />      <property name="trimStrings" value="true" />    </javaModelGenerator><!-- 制定映射文件 -->    <sqlMapGenerator targetPackage="mapper"  targetProject=".\src\main\resources">      <property name="enableSubPackages" value="true" />    </sqlMapGenerator><!-- 指定接口位置 -->    <javaClientGenerator type="XMLMAPPER" targetPackage="dao"  targetProject=".\src\main\java">      <property name="enableSubPackages" value="true" />    </javaClientGenerator><!-- tablie表生成策略 -->    <table tableName="emp" domainObjectName="Employee">    </table><table tableName="dep" domainObjectName="Department"></table>  </context>    </generatorConfiguration>

2.java运行文件

   List<String> warnings = new ArrayList<String>();   boolean overwrite = true;

   File configFile = new File("mbg.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);
