1,.安裝逆向工程外掛

 <!--mybatis 逆向工程程式碼自動生成外掛-->
<plugin>
    <groupId>org.mybatis.generator</groupId>
    <artifactId>mybatis-generator-maven-plugin</artifactId>
    <version>1.3.6</version>
    <configuration>
        <!--配置檔案的位置-->
        <configurationFile
 
>GeneratorMapper.xml</configurationFile>
        <verbose>true</verbose>
        <overwrite>true</overwrite>
    </configuration>
</plugin>

2.逆向工程配置檔案，放到資源根目錄（資料庫連線四要素：驅動，地址，使用者名稱密碼）

<?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>
    <!-- 需要指定一個本地的mysql驅動 -->
    <classPathEntry location="D:\apache_work\mysql-connector-java-5.1.23.jar"/>
    <context id="tables" targetRuntime="MyBatis3">
        <commentGenerator>
            <property name="suppressAllComments" value
 
="true" />
        </commentGenerator>
        <!-- 配置資料庫連線資訊 -->
        <jdbcConnection driverClass="com.mysql.jdbc.Driver"
                        connectionURL="jdbc:mysql://localhost:3306/springboot"
                        userId="root"
                        password="333">
        </jdbcConnection>
        <!-- 指定生成實體類的存放位置-->
        <javaModelGenerator targetPackage="com.bjpowernode.springboot.pojo"
                            targetProject="src/main/java">
            <property name="enableSubPackages" value="false" />
            <property name="trimStrings" value="false" />
        </javaModelGenerator>
        <!--指定生成的mapper的位置 -->
        <sqlMapGenerator targetPackage="com.bjpowernode.springboot.mapper"
                         targetProject="src/main/java">
            <property name="enableSubPackages" value="false" />
        </sqlMapGenerator>
        <!--指定生成的dao介面位置-->
        <javaClientGenerator type="XMLMAPPER"
                             targetPackage="com.bjpowernode.springboot.mapper" targetProject="src/main/java">
            <property name="enableSubPackages" value="false" />
        </javaClientGenerator>
        
        <!-- 指定生成哪些表對應的實體類，與生成的實體類名-->
        <table tableName="tbl_student" domainObjectName="Student"
               enableCountByExample="false"
               enableUpdateByExample="false"
               enableDeleteByExample="false"
               enableSelectByExample="false"
               selectByExampleQueryId="false"/>
    </context>
</generatorConfiguration>

點選外掛，並執行，完成
