注意：先匯入mybatis-generator-core相關包

一、建立相關配置檔案mbg.xm

mbg.xml編寫方法見MyBatis Generator參考文件:http://www.mybatis.org/generator/configreference/xmlconfig.html

<?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">

		<!--不加註釋 -->
		<commentGenerator>
			<property name="suppressAllComments" value="true" />
		</commentGenerator>

		<!--配置資料庫連線 -->
		<jdbcConnection driverClass="com.mysql.jdbc.Driver"
			connectionURL="jdbc:mysql://localhost:3306/ssm_crud" userId="root"
			password="123456">
		</jdbcConnection>

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

		<!--指定Javabean的生成位置 -->
		<javaModelGenerator targetPackage="com.atguigu.crud.bean"
			targetProject="./src/main/java">
			<property name="enableSubPackages" value="true" />
			<property name="trimStrings" value="true" />
		</javaModelGenerator>
		<!--指定sql對映檔案生成的位置 -->
		<sqlMapGenerator targetPackage="mapper" targetProject="./src/main/resources">
			<property name="enableSubPackages" value="true" />
		</sqlMapGenerator>
		<!--指定mapper介面生成的位置 -->
		<javaClientGenerator type="XMLMAPPER"
			targetPackage="com.atguigu.crud.dao" targetProject="./src/main/java">
			<property name="enableSubPackages" value="true" />
		</javaClientGenerator>

		<!--指定每個表的生成策略 -->
		<table tableName="tbl_emp" domainObjectName="Employee"></table>
		<table tableName="tbl_dept" domainObjectName="Department"></table>

	</context>
</generatorConfiguration>
 

二、建立MBGTest.java

MBGTest.java編寫方法見http://www.mybatis.org/generator/running/runningWithJava.html

package com.atguigu.crud.test;

import java.io.File;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;

import org.mybatis.generator.api.MyBatisGenerator;
import org.mybatis.generator.config.Configuration;
import org.mybatis.generator.config.xml.ConfigurationParser;
import org.mybatis.generator.exception.XMLParserException;
import org.mybatis.generator.internal.DefaultShellCallback;

public class MBGTest {
	public static void main(String[] args) 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);
	}
}
 

三、執行MBGTest.java

右擊程式碼-Run As-Java Application，稍等片刻。
