使用mybatis-generator-core-1.3.2.jar根据数据库表自动生成实体

1 导入mybatis-generator-core-1.3.2.jar

2配置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>

<!--
targetRuntime="MyBatis3Simple":生成简单版的CRUD
MyBatis3:豪华版

-->
<context id="DB2Tables" targetRuntime="MyBatis3">
<!-- jdbcConnection：指定如何连接到目标数据库 -->
<jdbcConnection driverClass="com.mysql.jdbc.Driver"
connectionURL="jdbc:mysql://localhost:3306/mybatis"
userId="root"
password="root">
</jdbcConnection>

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

<!-- javaModelGenerator：指定javaBean的生成策略
targetPackage="test.model"：目标包名
targetProject="MBGTestProjectsrc"：目标工程
-->
<javaModelGenerator targetPackage="com.atguigu.mybatis.bean"
targetProject=".src">
<property name="enableSubPackages" value="true" />
<property name="trimStrings" value="true" />
</javaModelGenerator>

<!-- sqlMapGenerator：sql映射生成策略：-->
<sqlMapGenerator targetPackage="com.atguigu.mybatis.dao"
targetProject=".conf">
<property name="enableSubPackages" value="true" />
</sqlMapGenerator>

<!-- javaClientGenerator:指定mapper接口所在的位置 -->
<javaClientGenerator type="XMLMAPPER" targetPackage="com.atguigu.mybatis.dao"
targetProject=".src">
<property name="enableSubPackages" value="true" />
</javaClientGenerator>

<!-- 指定要逆向分析哪些表：根据表要创建javaBean -->
<table tableName="department" domainObjectName="Department"></table>
<table tableName="tbl_employee" domainObjectName="Employee"></table>
</context>
</generatorConfiguration>

3 运行 mbg.xml

@Test
public void testMbg() throws Exception {
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);
}
