【AOP系列】一个切面类搞定请求日志

后端开发过程中接口调用的日志

折腾了又折腾，改了又改，怎么弄都弄不好？

试试这个

依赖

<!--SpringBoot-aop   HttpLogAspect类依赖-->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-aop</artifactId>
</dependency>

效果

HttpLogAspect.java

import lombok.extern.slf4j.Slf4j;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.*;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;

import javax.servlet.http.HttpServletRequest;
import java.util.Arrays;
import java.util.Date;

@Slf4j
@Aspect
@Component
public class HttpLogAspect {

    @Pointcut("execution(* 【包名】.controller.*.*(..))")//拦截所有Controller类的方法
    public void log() {
    }
    @Before("log()")
    public void doBefore(JoinPoint joinPoint) {
        HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();
        String packClassName = joinPoint.getSignature().getDeclaringTypeName();
        String className = joinPoint.getSignature().getDeclaringType().getSimpleName();
        String method = joinPoint.getSignature().getName();
        System.out.println();
        log.info("URL={}", request.getRequestURL());
        log.info("Method={}", request.getMethod());
        log.info("IP={}", request.getRemoteAddr());
        log.info("Class.Method={}", packClassName + "." + method + "(" + className + ".java:1)");
        log.info("ContentType={}", request.getContentType());
        log.info("Args={}", joinPoint.getArgs());
    }
    
     @After("log()")
    public void doAfter() {
    }
    @AfterReturning(returning = "response", pointcut = "log()")
    public void doAfterReturning(Object response) {
        log.debug("response={}", response);
    }


}

耗时接口插入数据库？

@Autowired
  SysLogMapper sysLogMapper;
  @Around("log()")
  public Object doAround(ProceedingJoinPoint point) {
      long beginTime = System.currentTimeMillis();
      try {
          return point.proceed();//放行操作
      } catch (Throwable throwable) {
          log.error(throwable.getMessage());
          return Result.getErrorResult("后台ERROR:" + throwable.getMessage());
          //return返回错误信息即可，本文没有提供Result类，自己处理即可。
      }finally {

          long time = System.currentTimeMillis() - beginTime;
          log.info("请求耗时={}", time);

          if (time>1000){//接口耗时超过1秒钟  加入日志到数据库
              HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();
              String operation = "【耗时接口】";
              SysLog sysLog = new SysLog();
              sysLog.setOperation(operation);
              sysLog.setUrl(request.getRequestURL().toString());
              sysLog .setIp(request.getRemoteAddr());
              sysLog.setMethod(request.getMethod());
              sysLog.setParams(Arrays.toString(point.getArgs()));
              sysLog.setUseTime(time);
              sysLog.setCreateTime(new Date());
              sysLogMapper.insert(sysLog);
              log.info("耗时接口已加入日志");
          }

          //【知识点】finally 会在 try 和catch 的return语句之前执行，
          //如果finally内又return,try和catch里的return不生效

      }
  }
