**1.新建Mavne项目，pom.xml加入如下代码：**

<dependencies>
    		<dependency>
    			<groupId>mysql</groupId>
    			<artifactId>mysql-connector-java</artifactId>
    			<version>5.1.46</version>
    		</dependency>
    	</dependencies>
    
    	<build>
            <plugins>
                <plugin>
                    <groupId>org.mybatis.generator</groupId>
                    <artifactId>mybatis-generator-maven-plugin</artifactId>
                    <version>1.3.2</version>
                    <configuration>
                    	
                    	<configurationFile>src/main/resources/mybatis-generator/generatorConfig.xml</configurationFile>
                      <verbose>true</verbose>
                      <overwrite>false</overwrite>
                    </configuration>
                    <dependencies>
    				        <dependency>
    				            <groupId>org.mybatis.generator</groupId>
    				            <artifactId>mybatis-generator-core</artifactId>
    				            <version>1.3.2</version>
    				        </dependency>
    				    </dependencies>
                </plugin>
            </plugins>
        </build>

2.在resouce下新建一个Folder：mybatis-generator

**3.在mybatis-generator下新建一个xml文件：generatorConfig.xml**

3.1.需要修改的地方，mysql配置，mapper，xml，entity的包路径，数据库表名，表对应的entity名称

3.2在本地D:\\Java\\mysql-connector-java-5.1.46.jar放入一个jar包

<?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>
    
    	<properties resource="mysql.properties"/>
    
    	<classPathEntry location="D:\Java\mysql-connector-java-5.1.46.jar" />
    	<context id="my" targetRuntime="MyBatis3">
    		<commentGenerator>
    			<property name="suppressDate" value="false" />
    			<property name="suppressAllComments" value="true" />
    		</commentGenerator>
    
    		
    		
    			
    		
    		<jdbcConnection driverClass="${spring.datasource.driver-class-name}"
    			connectionURL="${spring.datasource.url}"
    			userId="${spring.datasource.username}" 
    			password="${spring.datasource.password}" />
    
    		
    		<javaModelGenerator targetPackage="com.itmayiedu.entity"
    			targetProject="src/main/java">
    			<property name="enableSubPackages" value="true" />
    			<property name="trimStrings" value="true" />
    		</javaModelGenerator>
    
    		
    		<sqlMapGenerator targetPackage="com.itmayiedu.xml"
    			targetProject="src/main/java">
    			<property name="enableSubPackages" value="true" />
    		</sqlMapGenerator>
    
    		
    		<javaClientGenerator targetPackage="com.itmayiedu.mapper"
    			targetProject="src/main/java" type="XMLMAPPER">
    			<property name="enableSubPackages" value="true" />
    		</javaClientGenerator>
    
    		
    
    		
    		<table tableName="m_app" domainObjectName="MApp"
    			enableCountByExample="false" enableUpdateByExample="false"
    			enableDeleteByExample="false" enableSelectByExample="false"
    			selectByExampleQueryId="false">
    			
    		</table>
    
    	</context>
    </generatorConfiguration>

**4.在resource下新建一个mysql.properties文件 ，修改相应数据库的配置**

spring.datasource.driver-class-name=com.mysql.jdbc.Driver
    spring.datasource.url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf8&characterSetResults=utf8
    spring.datasource.username=root
    spring.datasource.password=root

**5.右键项目Run As  --> Run Configurations**

**看到如下界面：**

**Goals输入命令：mybatis-generator:generate**

![70 2][] **看到如下说明代码生成成功了：**

![70 3][]** 最后刷新项目： **
