AOP实现业务日志及异常日志记录

Posted 2021-05-01 一味苦茶

  服务对外提供接口，若没有日志记录，出问题时，无法确认调用方还是系统内部造成的异常。那么日志记录便排上了用场，但是每个方法都记录调用参数，记录返回结果，若多人开发，日志记录不规范等等问题便闹人心。于是，结合AOP，完美解决该问题

 

@Component

@Aspect

public class ControllerAOP extends ServiceResource {

 

   @Pointcut("execution(* com.ywkc.gcs.resource..*.*(..))")

   public void pointcutResult() {

   }

 

   @Around("pointcutResult()")

   public Object handlerControllerMethod(ProceedingJoinPoint joinPoint) {

        Object result = null;

        String className =joinPoint.getTarget().getClass().getSimpleName();

        String methodName = className + "_" +getMethodName(joinPoint);

        try {

            LoggerUtil.error("method:"+ methodName + " params:" + Arrays.asList(joinPoint.getArgs()));

            result = joinPoint.proceed();

            LoggerUtil.error("method:"+ methodName + " result:" + result);

        } catch (Throwable e) {

            LoggerUtil.error("method:"+ methodName + " error:" + e);

            return packageResult(500, "系统异常，请联系管理员", "");

        }

        return result;

   }

 

   private String getMethodName(ProceedingJoinPoint joinPoint) {

        Signature signature =joinPoint.getSignature();

        MethodSignature methodSignature =(MethodSignature) signature;

        Method method = methodSignature.getMethod();

        return method.getName();

   }

 

}

注：com.ywkc.gcs.resource包下皆为对外提供的resf接口类

 

在spring文件中注册

   <context:component-scan base-package="com.ywkc.gcs" />

   <aop:aspectj-autoproxy/>

<aop:aspectj-autoproxy proxy-target-class="true" />

 

LoggerUtil.error为简化日志记录，避免每个类都定义

privatefinalstatic Logger logger = LoggerFactory.getLogger(App.class);

logger.error("日志记录");

 

LoggerUtil工具类代码如下

 

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

 

public class LoggerUtil {

 

   public static Logger getProvate() {

        return LoggerFactory.getLogger(newException().getStackTrace()[1].getClassName());

   }

 

   public static void info(String msg) {

        getProvate().info(msg);

   }

   

   public static void error(String msg) {

        getProvate().error(msg);

   }

}
