1、在pom.xml里添加maven插件

<plugin><groupId>org.mybatis.generator</groupId><artifactId>mybatis-generator-maven-plugin</artifactId><version>1.3.5</version><dependencies><dependency><groupId> mysql</groupId><artifactId> mysql-connector-java</artifactId><version> 5.1.39</version></dependency><dependency><groupId>org.mybatis.generator</groupId><artifactId>mybatis-generator-core</artifactId><version>1.3.5</version></dependency></dependencies><executions><execution><id>Generate MyBatis Artifacts</id><phase>package</phase><goals><goal>generate</goal></goals></execution></executions><configuration><!--允许移动生成的文件 --><verbose>true</verbose><!-- 是否覆盖 --><overwrite>true</overwrite><!-- 自动生成的配置 --><configurationFile>src/main/resources/mybatis-generator.xml</configurationFile></configuration></plugin>

2、在resources下创建mybatis-generator.xml

<?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">        <commentGenerator>            <property name="suppressDate" value="true"/>            <property name="suppressAllComments" value="true"/>        </commentGenerator>        <!--数据库链接地址账号密码-->        <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://192.168.3.155:3308/nonobank_app" userId="stb_nono_app" password="csstbnonobank@2016">        </jdbcConnection>        <javaTypeResolver>            <property name="forceBigDecimals" value="false"/>        </javaTypeResolver>        <!--生成Model类存放位置-->        <javaModelGenerator targetPackage="com.demo.model" targetProject="src/main/java">            <property name="enableSubPackages" value="true"/>            <property name="trimStrings" value="true"/>        </javaModelGenerator>        <!--生成映射文件存放位置-->        <sqlMapGenerator targetPackage="com.demo.mapper" targetProject="src/main/java">            <property name="enableSubPackages" value="true"/>        </sqlMapGenerator>        <!--生成Dao类存放位置-->        <!-- 客户端代码，生成易于使用的针对Model对象和XML配置文件 的代码                type="ANNOTATEDMAPPER",生成Java Model 和基于注解的Mapper对象                type="MIXEDMAPPER",生成基于注解的Java Model 和相应的Mapper对象                type="XMLMAPPER",生成SQLMap XML文件和独立的Mapper接口        -->        <javaClientGenerator type="ANNOTATEDMAPPER" targetPackage="com.demo.dao" targetProject="src/main/java">            <property name="enableSubPackages" value="true"/>        </javaClientGenerator>        <!--生成对应表及类名-->        <table tableName="user" domainObjectName="User" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>    </context></generatorConfiguration>

3、在src/main/java/com/demo/下创建dao、model、mapper文件夹。

4、在maven project下双击mybatis-generator插件下的mybatis-generator:generate
