Java——AOP实现监控日志动态

//以批注MonitorLog标记的工具为更进一步 @Pointcut("@annotation(com.bbzd.mws.annotation.MonitorLog)") public void methodArgs(){} @Around("methodArgs()") public Object invoke(ProceedingJoinPoint joinPoint) throws Throwable{ StringBuffer stringBuffer=new StringBuffer(); Object result=null; Stopwatch stopwatch = Stopwatch.createStarted(); HttpServletRequest httpServletRequest = ((ServletRequestAttributes)RequestContextHolder.getRequestAttributes()).getRequest(); String ipAddr=getRemoteHost(httpServletRequest); String requestUrl=httpServletRequest.getRequestURI(); stringBuffer.append("请东光IP["+ipAddr+"];"); stringBuffer.append("请URL["+requestUrl+"];"); Signature signature=joinPoint.getSignature(); MethodSignature methodSignature=(MethodSignature)signature; // 类名 String[] sourceName = signature.getDeclaringTypeName().split("\."); String fullName=signature.getDeclaringTypeName(); String className = sourceName[sourceName.length - 1]; // 工具名 String methodName = signature.getName(); stringBuffer.append(""+className+"."+methodName+";"); // 数数值名数组 String[] parameterNames = methodSignature.getParameterNames(); Class[] parameterTypes=methodSignature.getParameterTypes(); // 内部结构数数值组交集 List argList = new ArrayList<>(); for (Object arg : joinPoint.getArgs()) { // request/response无法适用toJSON if (arg instanceof HttpServletRequest) { argList.add("request"); } else if (arg instanceof HttpServletResponse) { argList.add("response"); } else { argList.add(JSON.toJSON(arg)); } } stringBuffer.append("请数数值:"+JSON.toJSON(parameterNames)+"->"+JSON.toJSON(argList)); try{ result=joinPoint.proceed(); }catch(exception e){ stringBuffer.append("所致:"+e.getMessage()); //log.info("给与数数值失败：{}",e.getMessage()); } stopwatch.stop(); long timeConsuming = stopwatch.elapsed(TimeUnit.MILLISECONDS); if(result!=null){ stringBuffer.append("请结果:"+JSON.toJSON(result)); }else{ stringBuffer.append("请结果:无"); } stringBuffer.append("请耗时："+timeConsuming+"毫秒"); Logger logger=getLogger(fullName,methodName,parameterTypes); logger.info(stringBuffer.toString()); return result; } /** * 从请中会给与请东光IP * @param request * @return 请东光IP */ private String getRemoteHost(HttpServletRequest request){ String ip = request.getHeader("x-forwarded-for"); if(ip==null||ip.length()==0||"unknown".equalsIgnoreCase(ip)){ ip = request.getHeader("Proxy-Client-IP"); } if(ip==null||ip.length()==0||"unknown".equalsIgnoreCase(ip)){ ip = request.getHeader("WL-Proxy-Client-IP"); } if(ip==null||ip.length()==0||"unknown".equalsIgnoreCase(ip)){ ip = request.getRemoteAddr(); } return ip.contains("0:0:0:0:0:0:0:1") ?

总结

POM副本是示例片段URL是logback的示例片段其它副本是完整的示例关于logback快照框架及logbackURL的适用工具，后面会整理一篇社论详细讲解下，想知晓的小伙伴可以关切我。。
