在pom中导入插件

<plugin>
    <!--Mybatis-generator插件,用于自动生成Mapper和POJO-->
    <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/mybatis-generator-config.xml</configurationFile>
        <verbose>true</verbose>
        <overwrite>true</overwrite>
    </configuration>
    <executions>
        <execution>
            <id>Generate MyBatis Artifacts</id>
            <goals>
                <goal>generate</goal>
            </goals>
        </execution>
    </executions>
    <dependencies>
        <dependency>
            <groupId>org.mybatis.generator</groupId>
            <artifactId>mybatis-generator-core</artifactId>
            <version>1.3.2</version>
        </dependency>
    </dependencies>
</plugin>

编写mybatis-generator-config.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>

    <!-- 本地数据库驱动程序jar包的全路径 -->
    <classPathEntry location="E:\开发\MYSQL\jar包\mysql-connector-java-5.1.46.jar"/>

    <context id="context" targetRuntime="MyBatis3">
        <commentGenerator>
            <!--为true不生成注释和时间戳-->
            <property name="suppressAllComments" value="true"/>
            <property name="suppressDate" value="true"/>
        </commentGenerator>

        <!-- 数据库的相关配置 -->
        <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://localhost:3306/demo" userId="root" password="root"/>

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

        <!-- 实体类生成的位置 -->
        <javaModelGenerator targetPackage="com.mlyr.pojo" targetProject="src/main/java">
            <property name="enableSubPackages" value="false"/>
            <property name="trimStrings" value="true"/>
        </javaModelGenerator>

        <!-- *Mapper.xml 文件的位置 -->
        <sqlMapGenerator targetPackage="com.mlyr.mapper" targetProject="src/main/java">
            <property name="enableSubPackages" value="false"/>
        </sqlMapGenerator>

        <!-- Mapper 接口文件的位置 -->
        <javaClientGenerator targetPackage="com.mlyr.mapper" targetProject="src/main/java" type="XMLMAPPER">
            <property name="enableSubPackages" value="false"/>
        </javaClientGenerator>

        <!-- 相关表的配置 -->
        <table tableName="emp" enableCountByExample="true" enableDeleteByExample="true" enableSelectByExample="true"
               enableUpdateByExample="true"/>
         <!-- 一次生成多张表 -->
        <table tableName="dept" enableCountByExample="true" enableDeleteByExample="true" enableSelectByExample="true"
               enableUpdateByExample="true"/>
    </context>
</generatorConfiguration>
