二、java代码
在main包下创建一个名为java的包，标记为resouce包，包中创建controller、service以及test包
（扩充）逆向生成：
在test包中创建一个测试类Test1
package com.test;
import org.junit.Test;
import org.mybatis.generator.api.MyBatisGenerator;
import org.mybatis.generator.config.Configuration;
import org.mybatis.generator.config.xml.ConfigurationParser;
import org.mybatis.generator.internal.DefaultShellCallback;
import java.io.File;
import java.util.ArrayList;
import java.util.List;
public class Test1 {
@Test
public void create() 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);
}
}
配置mbg.xml，用于逆向生成
<?xml version="1.0" encoding="UTF-8"?>

NUMERIC 类型解析为java.math.BigDecimal -->
<javaTypeResolver>
<property name="forceBigDecimals" value="false"/>
</javaTypeResolver>
<!-- 2.pojo类的生成配置 targetPackage表示目标文件夹
targetProject表示当前目标文件夹所放置的目标地址
-->
<javaModelGenerator targetPackage="com.pojo" targetProject=".\src\main\java">
<property name="enableSubPackages" value="true"/>
<property name="trimStrings" value="true"/>
</javaModelGenerator>
<!-- 3.sql映射文件生成配置 -->
<sqlMapGenerator targetPackage="mybatis/mapper" targetProject=".\src\main\resources">
<property name="enableSubPackages" value="true"/>
</sqlMapGenerator>
<!-- 4.mapper接口配置 -->
<javaClientGenerator type="XMLMAPPER" targetPackage="com.mapper" targetProject=".\src\main\java">
<property name="enableSubPackages" value="true"/>
</javaClientGenerator>
<!-- 5.数据库表和实体类映射 -->
<table tableName="emp" domainObjectName="Emp">
</table>
<table tableName="dept" domainObjectName="Dept">
</table>
</context>
</generatorConfiguration>
逆向生成的文件：
java包下：mapper包、pojo包。resources包下的myBatis包下：mapper包
mapper包下的DeptMapper接口
package com.mapper;
import com.pojo.Dept;
import com.pojo.DeptExample;
import java.util.List;
