前言
上一章springboot2.0实现日志集成的方法(2)主要讲解了将日志信息根据类别输出到不同的文件中，实际开发中我们需要通过日志来监控用户的操作行为、请求的耗时情况，针对耗时久的请求进行性能分析，提升系统性能。
具体实现
采用的spring aop切面技术来实现控用户的操作行为、请求的耗时情况。
定义日志注解
@target({ elementtype.method }) @retention(retentionpolicy.runtime) @documented public @interface logannotation { // 模块 string model() default ""; // 功能 string func() default ""; //描述 string desc() default ""; }
定义日志切面
@aspect @component public class logaspect { //请求监控日志，输出到不同日志文件 public static log logger = logmanager.getlogger("request-access"); /** * 定义切面 */ @pointcut("@annotation(com.test.aspect.logannotation)") private void logpoincut() { } /** * * @param joinpoint */ @before(value = "logpoincut恰卡编程网()") public void dobefore(joinpoint joinpoint) { string requestid =traceidutil.gettraceid(); logger.info("start invoke requestid:[{}]",requestid); } @around(value = "logpoincut()") public object doaround(proceedingjoinpoint jp) throws throwable { string requestid =traceidutil.gettraceid(); logger.info("enter request start requestid :[{}]",requestid); servletrequestattributes attributes = (servletrequestattributes) requestcontextholder .getrequestattributes(); httpservletrequest request = attributes.getrequest(); methodsignature signature = (methodsignature) jp.getsignature(); method method = signature.getmethod(); long starttime= system.currenttimemillis(); operationlog operationlog = new operationlog(); logannotation logannotation = method.getannotation(logannotation.class); if (logannotation != null) { string model = logannotation.model(); string func = logannotation.func(); string desc = logannotation.desc(); operationlog.setmodel(model); operationlog.setfunc(func); operationlog.setdesc(desc); } string classname = jp.gettarget().getclass().getname(); string methodname = jp.getsignature().getname(); string uri = request.getrequesturi(); string ip = iputil.getipaddr(request); operationlog.setclassname(classname); operationlog.setmethodname(methodname); operationlog.setip(ip); operationlog.seturi(uri); stringbuilder param = new stringbuilder(); object[] args = jp.getargs(); object arg = null; for (int i = 0, j = args.length; i < j; i ) { arg = args[i]; param.append(" ") .append(arg == null ? null : args[i].tostring()); if (i != (j - 1)) { param.append(",").append("\n"); } } operationlog.setparam(param.tostring()); operationlog.setcreatedate(new date()); long endtime=system.currenttimemillis()-starttime; //可以通过配置设置异常调用请求时间 long costtime=3; operationlog.setcosttime(endtime); string logstr = json.tojsonstring(operationlog); //将异常请求数据插入数据库 if(endtime>costtime){ //saveopetionlog(operationlog); } logger.info("invoke finish message:{}",logstr); object obj = jp.proceed(); return obj; } /** * 方法之后调用 * @param joinpoint * @param returnvalue 方法返回值 */ @afterreturning(pointcut = "logpoincut()") public void doafterreturning(joinpoint joinpoint) { string requestid=traceispring boot logbck mdc来实现。
