springboot、springmvc攔截器，日誌記錄器，統一日誌處理

每次搭建新項目都會用到攔截器，這次把以前用過的一個攔截器進行改造了一下，放blog做個記錄

 

package com.xxx.aop;

import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.Signature;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.core.annotation.Order;
import org.springframework.stereotype.Component;



@Aspect
@Order
@Component
public class LogAspect {

    private static final Logger logger = LoggerFactory.getLogger(LogAspect.class);


    @Around(value = "execution(* com.xxx.service..*.*(..))")
    public Object printLog(ProceedingJoinPoint jp) {
        CallerInfo info = null;
        Object ret = null;
        long startTime = System.currentTimeMillis();
        try {
            String key = getMethodName(jp);

            info = Profiler.registerInfo(key, false, true);

            ret = jp.proceed();
            logCompleted(jp, ret, startTime);

            Profiler.registerInfoEnd(info);
            return ret;
        } catch (Throwable throwable) {
            String exInfo = logException(jp, startTime, throwable);

            Profiler.functionError(info);
            return ResultUtils.wrapFailure(500, exInfo);
        }
    }

    private void logCompleted(ProceedingJoinPoint jp, Object ret, long startTime) {
        StringBuilder sb = new StringBuilder();
        logBasic(sb, jp, startTime);
        logSuccessResult(sb, ret);
        logger.info(sb.toString());
    }

    private String logException(ProceedingJoinPoint jp, long startTime, Throwable throwable) {
        StringBuilder sb = new StringBuilder();
        logBasic(sb, jp, startTime);
        logExceptionResult(sb, throwable);
        String message = sb.toString();
        logger.error(message);
        return message;
    }

    private void logBasic(StringBuilder sb, ProceedingJoinPoint jp, long startTime) {
        String params = "";
        try {
            if (jp.getArgs() != null) {
                params = JSON.toJSONString(jp.getArgs());
            }
        } catch (Exception ex) {
            logger.warn("aop序列化參數失敗", ex);
        }
        buildPrefix(sb, jp, startTime);
        sb.append("#parameter:");
        sb.append(params);
        sb.append("#result:");
    }

    private void logExceptionResult(StringBuilder sb, Throwable throwable) {
        String result = throwable.toString();
        sb.append(result);
        sb.append("###stack:");
        sb.append(ExceptionUtil.getStackTrace(throwable));
    }

    private void logSuccessResult(StringBuilder sb, Object ret) {
        String result = "";
        try {
            if (ret != null) {
                result = JSON.toJSONString(ret);
            }
        } catch (Exception ex) {
            logger.warn("aop序列化結果失", ex);
        }
        sb.append(result);
    }


    private void buildPrefix(StringBuilder sb, ProceedingJoinPoint jp, long startTime) {
        long cost = System.currentTimeMillis() - startTime;
        String clazz = jp.getTarget().getClass().getSimpleName();
        String method = jp.getSignature().getName();
        sb.append("class:");
        sb.append(clazz);
        sb.append("#method:");
        sb.append(method);
        sb.append("#cost:");
        sb.append(cost);
    }

    private String getMethodName(ProceedingJoinPoint jp) {
        StringBuilder sb = new StringBuilder();
        String clazz = jp.getTarget().getClass().getName();
        String method = jp.getSignature().getName();
        sb.append(clazz);
        sb.append(".");
        sb.append(method);
        return sb.toString();

    }

}

 

 

插入一個異常詳細信息收集器

 

public static String getStackTrace(Throwable throwable) {
        StringWriter sw = new StringWriter();
        PrintWriter pw = new PrintWriter(sw);

        try {
            throwable.printStackTrace(pw);
            return sw.toString();
        } finally {
            pw.close();
            try {
                sw.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }

記錄結果如下：
