1 准备逆向工程的项目

2 在pom文件中引入mbg的依赖+插件

---

<dependency>

    <groupId>org.mybatis.generator</groupId>

    <artifactId>mybatis-generator-core</artifactId>

    <version>1.3.7</version>

</dependency>

<plugin>

    <groupId>org.mybatis.generator</groupId>

    <artifactId>mybatis-generator-maven-plugin</artifactId>

    <version>1.3.7</version>

    <dependencies>

        <dependency>

            <groupId>mysql</groupId>

            <artifactId>mysql-connector-java</artifactId>

            <version>5.1.42</version>

        </dependency>

    </dependencies>

</plugin>

3 在resources下准备逆向工程配置文件

generatorConfig.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="MySQLTables" targetRuntime="MyBatis3">

<commentGenerator>

<property name="suppressAllComments" value="true" />

</commentGenerator>

<!-- mvn mybatis-generator:generate 配置数据库位置 ，配置虚拟机上的mysql ip地址；不采用安全协议连接，否则无法逆向生成 -->

<jdbcConnection driverClass="com.mysql.jdbc.Driver"

connectionURL="jdbc:mysql://192.168.1.1:3306/scw??useSSL=false&amp;useUnicode=true&amp;characterEncoding=UTF-8&amp;serverTimezone=Asia/Shanghai"

userId="root" password="123456">

</jdbcConnection>

<javaTypeResolver>

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

</javaTypeResolver>

<!-- javaBean生成在哪里 -->

<javaModelGenerator

targetPackage="com.atguigu.springboot.ssm.bean"

targetProject=".\src\main\java">

<property name="enableSubPackages" value="true" />

<property name="trimStrings" value="true" />

</javaModelGenerator>

<!-- sqlMap sql映射文件（xml mapper文件） -->

<sqlMapGenerator targetPackage="mybatis.mapper"

targetProject=".\src\main\resources">

<property name="enableSubPackages" value="true" />

</sqlMapGenerator>

<!-- javaClient：java接口生成的地方 -->

<javaClientGenerator type="XMLMAPPER"

targetPackage="com.atguigu.springboot.ssm.mapper"

targetProject=".\src\main\java">

<property name="enableSubPackages" value="true" />

</javaClientGenerator>

<table schema="" tableName="%"></table>

<!-- <table schema="TPermission" tableName="t_permission"></table> -->

</context>

</generatorConfiguration>

4 执行逆向工程

5. 在项目的主程序类名上添加MapperScan注解：扫描所有的Mapper接口

---

//指定mapper接口所在的包，主程序会自动将该包下的所有的接口当成组件和mapper映射文件对应创建对象

@MapperScan(basePackages = "com.atguigu.springboot.ssm.mapper")

@SpringBootApplication

public class SpringbootSsmApplication {

    public static void main(String[] args) {

        SpringApplication.run(SpringbootSsmApplication.class, args);

    }

}
