配置要点:
- 驱动配置 application.properties
spring.datasource.driver-class-name=com.p6spy.engine.spy.P6SpyDriver spring.datasource.url=jdbc:p6spy:mysql://localhost:3306/demo_datasource
- psy配置
# 单行日志 logMessageFormat=com.p6spy.engine.spy.appender.SingleLineFormat # 使用Slf4J记录sql appender=com.p6spy.engine.spy.appender.Slf4JLogger # 是否开启慢SQL记录 outagedetection=true # 慢SQL记录标准,单位秒 outagedetectioninterval=2
使用aop实现;
package com.springbootpractice.demo.p6spy.aop; import lombok.SneakyThrows; import lombok.extern.slf4j.Slf4j; import org.aspectj.lang.ProceedingJoinPoint; import org.aspectj.lang.annotation.Around; import org.aspectj.lang.annotation.Aspect; import org.aspectj.lang.annotation.Pointcut; import org.springframework.stereotype.Component; import org.springframework.util.StopWatch; /** * 说明:aop配置 * @author carter * 创建时间: 2020年02月16日 8:49 下午 **/ @Aspect @Component @Slf4j public class PrintTimeCostAspectJConfig { @SneakyThrows @Around("myPointCut()") public Object around(ProceedingJoinPoint pj) { Object res = null; String methodName = pj.getSignature().toShortString(); StopWatch stopWatch = new StopWatch(methodName); stopWatch.start(); try { res = pj.proceed(); } catch (Throwable ex) { throw ex; } finally { stopWatch.stop(); log.warn("{}执行耗时{}毫秒", methodName, stopWatch.getTotalTimeMillis()); } return res; } @Pointcut("execution(* com.springbootpractice.demo.p6spy.web..*(..))") public void myPointCut() { } }
启用aop注解:
@EnableAspectJAutoProxy(proxyTargetClass = true)
来个效果截图:
通过本片文章,你可以学会:
- 给代码添加aop切面,增加日志或者打印出方法执行总耗时;
- 给你的数据持久层打印出所有的sql语句,方便生产环境排查问题;
希望大家平安度过冠疫!每天持续精进!
