  <dependency>
            <groupId>p6spy</groupId>
            <artifactId>p6spy</artifactId>
            <version>3.8.0</version>
        </dependency>

• application.yml 配置：

spring:
  datasource:
    driver-class-name: org.h2.Driver
    url: jdbc:h2:tcp://192.168.180.115:19200/~/mem/test
    username: root
    password: test
​
mybatis-plus:
  global-config:
    db-config:
      id-type: id_worker
      capital-mode: true
  configuration:
    log-impl: org.apache.ibatis.logging.stdout.StdOutImpl

• spy.properties 配置：

module.log=com.p6spy.engine.logging.P6LogFactory,com.p6spy.engine.outage.P6OutageFactory
# 自定義日志打印
logMessageFormat=com.baomidou.mybatisplus.extension.p6spy.P6SpyLogger
#日志輸出到控制台
appender=com.baomidou.mybatisplus.extension.p6spy.StdoutLogger
# 使用日志系統記錄 sql
#appender=com.p6spy.engine.spy.appender.Slf4JLogger
# 設置 p6spy driver 代理
deregisterdrivers=true
# 取消JDBC URL前綴
useprefix=true
# 配置記錄 Log 例外,可去掉的結果集有error,info,batch,debug,statement,commit,rollback,result,resultset.
excludecategories=info,debug,result,batch,resultset
# 日期格式
dateformat=yyyy-MM-dd HH:mm:ss
# 實際驅動可多個
#driverlist=org.h2.Driver
# 是否開啟慢SQL記錄
outagedetection=true
# 慢SQL記錄標准 2 秒
outagedetectioninterval=2

• 配置類,官網已經棄用了插件，推薦使用P6spy

  @Configuration
  public class MybatisPlusConfig {
  ​
  //    該插件 3.1.2 后版本廢棄，推薦使用
  //    @Bean
  //    public PerformanceInterceptor performanceInterceptor(){
  //        //啟用性能分析插件
  //        return new PerformanceInterceptor();
  //    }
  }

• 實體類

  @Data
  @TableName(value = "student")
  public class Student {
  ​
      private Long id;
  ​
      private String name;
  ​
      private Integer age;
  ​
  }
  ​
  @Mapper
  public interface StudentMapper extends BaseMapper<Student> {
  ​
  ​
  }
  ​

• 測試類

  ​
  @SpringBootTest
  class EanalysisApplicationTests {
  ​
      @Autowired
      private StudentMapper studentMapper;
  ​
      @Test
      public void test(){
          studentMapper.selectList(new QueryWrapper<>());
      }
  ​
  ​
  }
