idea中自动生成代码

1.pom文件

<plugins>
    <plugin>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-maven-plugin</artifactId>
    </plugin>
    <!-- mybatis逆向工程 -->
    <plugin>
        <groupId>org.mybatis.generator</groupId>
        <artifactId>mybatis-generator-maven-plugin</artifactId>
        <version>1.3.2</version>
        <configuration>
            <!--配置文件的位置-->
            <configurationFile>src/main/resources/generatorConfig.xml</configurationFile>
            <verbose>true</verbose>
            <overwrite>true</overwrite>
        </configuration>
    </plugin>
</plugins>

2.generatorConfig.xml （对应pom文件中配置文件位置）（注意maper,pojo,service的src修改）

<?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>
    <!--数据库驱动-->
    <classPathEntry    location="D:\idea\install\IntelliJ IDEA 2019.2.3\bin\mysql-connector-java-5.1.0-bin.jar"/>

    <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://localhost/picture" userId="root" password="123456">
        </jdbcConnection>
        <javaTypeResolver>
            <property name="forceBigDecimals" value="false"/>
        </javaTypeResolver>
        <!--生成POJO(Model)类存放位置-->
        <javaModelGenerator targetPackage="cn.kgc.pojo" targetProject="src">
            <property name="enableSubPackages" value="true"/>
            <property name="trimStrings" value="true"/>
            <property name="constructorBased" value="true"/>

        </javaModelGenerator>
        <!--生成Mapper映射文件存放位置-->
        <sqlMapGenerator targetPackage="cn.kgc.mappering" targetProject="src">
            <property name="enableSubPackages" value="true"/>
        </sqlMapGenerator>
        <!--生成Dao类存放位置-->
        <javaClientGenerator type="XMLMAPPER" targetPackage="cn.kgc.mapper" targetProject="src">
            <property name="enableSubPackages" value="true"/>
        </javaClientGenerator>
        <!--生成对应表及类名-->

        <table tableName="picture" domainObjectName="Picture" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false">
            <property name="useActualColumnNames" value="false"/>
        </table>
    </context>
</generatorConfiguration>

3.选择菜单栏Run ->edit Cofiguerations—>左上角的+号—》选择maven：如图



4.执行生成model，双击即可

5.以下结果便是构建成功啦
