IntelliJ IDEA mybatis-generator逆向工程生成代码

1）导入maven依赖

 <!-- https://mvnrepository.com/artifact/org.mybatis.generator/mybatis-generator-core -->
        <dependency>
            <groupId>org.mybatis.generator</groupId>
            <artifactId>mybatis-generator-core</artifactId>
            <version>1.3.7</version>
        </dependency>

2）在resources资源下添加逆向生成文件

<?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>
<!--加载jdbc.properties-->
	<properties resource="jdbc.properties"></properties>
	<context id="DB2Tables" targetRuntime="MyBatis3">
		<!-- 生成没有注释的实体类 -->
		<commentGenerator>
			<property name="suppressAllComments" value="true" />
		</commentGenerator>
		<!-- 配置数据库连接 -->
		<jdbcConnection driverClass="${driverClassName}"
			connectionURL="${url}"
			userId="${username}"
			password="${password}">
		</jdbcConnection>

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

		<!-- 指定JavaBean生成的位置 -->
		<javaModelGenerator targetPackage="com.example.bean"
			targetProject=".\src\main\java">
			<property name="enableSubPackages" value="true" />
			<property name="trimStrings" value="true" />
		</javaModelGenerator>

		<!--指定sql映射文件生成的位置 -->
		<sqlMapGenerator targetPackage="com.example.dao"
		targetProject=".\src\main\java">
			<property name="enableSubPackages" value="true" />
		</sqlMapGenerator>

		<!-- 指定dao接口生成的位置，mapper接口 -->
		<javaClientGenerator type="XMLMAPPER"
			targetPackage="com.example.dao"
			targetProject=".\src\main\java">
			<property name="enableSubPackages" value="true" />
		</javaClientGenerator>


		<!-- table指定每个表的生成策略 -->
		<table tableName="items" domainObjectName="Items"></table>

	</context>
</generatorConfiguration>

3）创建main方法调用逆向文件，生成JavaBean、Mapper映射

package com.ssm.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.io.InputStream;
import java.util.ArrayList;
import java.util.List;

public class TestGen {

    public static void main(String[] args) throws Exception {

        List<String> warnings = new ArrayList<String>();
        boolean overwrite = true;
        ConfigurationParser cp = new ConfigurationParser(warnings);
        //构造输入流对象
        InputStream is = Thread.currentThread().getContextClassLoader().getResourceAsStream("mbg.xml");
        Configuration config = cp.parseConfiguration(is);
        DefaultShellCallback callback = new DefaultShellCallback(overwrite);
        MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config, callback, warnings);
        myBatisGenerator.generate(null);
    }
}

4）如果效果图如下就生成成功了
