SpringBoot集成Mybatis-Plus、Druid（SQL监控）

1.创建springboot项目，先实现mybatis-plus、druid

2.pom文件引入

<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><optional>true</optional></dependency><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>5.1.47</version></dependency><dependency><groupId>com.alibaba</groupId><artifactId>druid</artifactId><version>1.1.10</version></dependency><!--注意引入druid需要引入log4j，不然会报错--><dependency><groupId>log4j</groupId><artifactId>log4j</artifactId><version>1.2.17</version></dependency><dependency><groupId>com.baomidou</groupId><artifactId>mybatis-plus-boot-starter</artifactId><version>3.2.0</version></dependency>

启动项目测试：http://localhost:8080/test/getUser

http://localhost:8080/druid/login.html 使用配置的账号密码登陆

自此springboot集成mybatis、druid成功。
