## 1、创建配置文件 ##

在项目的src/main/resources目录下创建generatorConfig.xml配置文件，文件内容如下：

<?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>
        
        <classPathEntry location="G:\mysql-connector-java-5.1.6-bin.jar"/>
        <context id="DB2Tables" targetRuntime="MyBatis3">
            <commentGenerator>
                <property name="suppressDate" value="true"/>
                
                <property name="suppressAllComments" value="true"/>
            </commentGenerator>
            
            <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://localhost:3306/stu_help" userId="root" password="123456">
            </jdbcConnection>
            
            <javaTypeResolver>
                <property name="forceBigDecimals" value="false"/>
            </javaTypeResolver>
            
            <javaModelGenerator targetPackage="per.xmx.stuhelp.entity" targetProject="src/main/java">
            </javaModelGenerator>
            
            <sqlMapGenerator targetPackage="mybatis/mappers/" targetProject="src/main/resources">
            </sqlMapGenerator>
            
            <javaClientGenerator type="XMLMAPPER" targetPackage="per.xmx.stuhelp.dao" targetProject="src/main/java">
            </javaClientGenerator>
            
            <table tableName="t_user" domainObjectName="User" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
        </context>
    </generatorConfiguration>

## 2、在pom.xml文件中添加插件 ##

<plugin>
        <groupId>org.mybatis.generator</groupId>
        <artifactId>mybatis-generator-maven-plugin</artifactId>
        <version>1.3.5</version>
        <configuration>
           
           <configurationFile>src/main/resources/mybatis/generatorConfig.xml</configurationFile>
        </configuration>
    </plugin>

## 3、运行maven插件 ##

1）在IDEA中：

2）在pom.xml文件所在位置使用maven命令：

mvn mybatis-generator:generate

3）在Eclipse中：
