1.先创建springboot项目,然后会有如下依赖(aop是自己加上去的)

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-aop</artifactId>
</dependency>

2.然后添加mysql驱动包
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.46</version>
</dependency>

3.还要添加druid数据连接池(其他连接池也行,建议使用druid)
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>druid</artifactId>
<version>1.0.9</version>
</dependency>
4.在application.properties配置文件中添加配置
#(默认端口号,可不配置)
server.port=8080
#连接mysql和连接池
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf-8&useSSL=true&serverTimezone=UTC
spring.datasource.username=root
spring.datasource.password=root
#配置mysql数据库字段和实体属性映射
mybatis.configuration.map-underscore-to-camel-case=true
#添加sql日志(debug级别-level后面为你mapper接口的路径)

logging.level.com.example.mybatis.mapper=debug
#如果mapper.xml文件在resources下则需要此配置(classpath后面的mapper为存放xml文件的包)
mybatis.mapper-locations=classpath:mapper/*.xml
#如果Mapper的xml映射文件在src/main/java包下时,需要此配置
<resources>
<resource>
<directory>src/main/java</directory>
<includes>
<include>**/*.xml</include>
</includes>
</resource>
<resource>
<directory>src/main/resources</directory>
</resource>
</resources>

5.配置完成之后,我们再添加一个mybatis-generator插件用来生成代码,我添加在了如下位置

打开generatorConfig.xml,如下
<?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>
<!--指定maven仓库中jdbc驱动jar包的位置-->
<classPathEntry location="E:\apache-maven-3.2.5\repository\mysql\mysql-connector-java\8.0.13\mysql-connector-java-8.0.13.jar"/>
<!-- 一个数据库一个context -->
<context id="DB2Tables" targetRuntime="MyBatis3">
<commentGenerator>
<property name="suppressDate" value="true"/><!-- 是否生成注释代时间戳 -->
<property name="suppressAllComments" value="true"/><!-- 是否去除自动生成的注释 true是 false:否 -->
</commentGenerator>
<!--数据库链接URL,用户名、密码 -->
<jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://127.0.0.1/test?serverTimezone=GMT" userId="root" password="root">
<property name="nullCatalogMeansCurrent" value="true" />
</jdbcConnection>
<!-- 类型转换 -->
<javaTypeResolver>
<!-- 默认false,把JDBC DECIMAL和NUMERIC类型解析为 Integer;为true时则解析为java.math.BigDecimal -->
<property name="forceBigDecimals" value="false"/>
</javaTypeResolver>
<!-- 生成model的包名和位置-->
<javaModelGenerator targetPackage="com.example.mybatis.model" targetProject="src/main/java">
<property name="enableSubPackages" value="true"/>
<property name="trimStrings" value="true"/>
</javaModelGenerator>
<!-- 生成Mapper映射XML文件位置-->
<sqlMapGenerator targetPackage="mapper" targetProject="src/main/resources">
<property name="enableSubPackages" value="true"/>
</sqlMapGenerator>
<!-- 生成Mapper接口文件位置-->
<javaClientGenerator type="XMLMAPPER" targetPackage="com.example.mybatis.mapper" targetProject="src/main/java">
<property name="enableSubPackages" value="true"/>
</javaClientGenerator>
<!-- 要生成的表 tableName是数据库中的表名或视图名 domainObjectName是实体类名-->
<table tableName="sys_permission" domainObjectName="Permission"
enableCountByExample="true" enableUpdateByExample="true"
enableDeleteByExample="true" enableSelectByExample="true"
selectByExampleQueryId="true">
</table>
</context>
</generatorConfiguration>

6.在pom的plugins标签下添加插件依赖
<plugin>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-maven-plugin</artifactId>
  #版本
<version>1.3.2</version>
<configuration>
    此位置是上面截图的位置(你放在哪里就写在哪里)
<configurationFile>D:\mybatis\src\main\resources\generate\generatorConfig.xml</configurationFile>
<verbose>true</verbose>
<overwrite>true</overwrite>
</configuration>
<executions>
<execution>
<id>Generate MyBatis Artifacts</id>
<!--maven生成jar包时 避免运行generator插件(这个必须要加上,否则mapper接口和xml会在重新生成)-->
<phase>deploy</phase>
<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>
