问题 I need to print username and client IP address in logs.but username is only prints for first thread using MDC in log4j.From next thread the values are printed as empty. can any one suggest how to proceed further on this . 回答1: MDC uses ThreadLocal to store values. Maybe Log4J (like Logback) uses InheritableThreadLocal which partially solves problems like yours: newly created thread inherits MDC from parent thread. I guess you are using some sort of pooling (we are rarely creating dedicated

问题 When working on a large Firefox plugin, I sometimes accidentally make a syntax error not caught by my editor. When this happens, then calling Components.utils.import("resource://modules/Foo.js") will simply fail to import or return anything, without any kind of helpful hint as to where in the file to look for the syntax error. Is there any way I can get Firefox to give me some kind of clue when my imports fail? EDIT: I fixed my own problem, which turned out to be that I was using code which

问题 How can I achieve MDC Logging (Java) in GoLang? I need to add UUIDs in all server logs in order to be able to trace concurrent requests. 回答1: Java MDC relies on thread local storage, something Go does not have. The closest thing is to thread a Context through your stack. This is what more and more libraries are doing in Go. A somewhat typical way is to do this via a middleware package that adds a request id to the context of a web request, like: req = req.WithContext(context.WithValue(req

问题 Akka and Scala newbie here, please feel free to edit the question as necessary in order to clearly articulate my intent in the domain of Scala and Akka. Before I show code snippets, here's the problem I want to solve: I essentially want to develop a common module for my team to use when they're developing their applications using Akka actors. I want to allow them to mixin a trait which will extend their receive functionality at runtime, mainly for logging purposes. I'm running into compile

问题 After going back to an older project and getting around to update its dependencies I had to realize that logback does not anymore propagate MDCs to children since version 1.1.5 : https://github.com/qos-ch/logback/commit/aa7d584ecdb1638bfc4c7223f4a5ff92d5ee6273 This change makes most of the logs nigh useless. While I can understand the arguments given in the linked issues, I can not understand why this change could not have been made in a more backwards compatible manner (as is generally usual

问题 I want to implement logback MDC logging on my AKKA application to organize and have a more infomative log; however, I also read that MDC might not work well with AKKA because AKKA has asynchronous logging system (MDC might be stored on a different thread). I used the Custom Dispatcher for MDC Logging defined here hoping to solve my problem but I can't make it work on my application. My application is not a play framework app though. I have a RequestHandler Actor that receives different types

问题 I am using MDC Logger, which is perfectly working for me except in one case. Wherever in the code we have used CompletableFuture, for the created thread the MDC data is not getting passed to next thread and due to which Logs are failing. For example in the code I have used below snippet for creating new Thread. CompletableFuture.runAsync(() -> getAcountDetails(user)); And the result of logs as below 2019-04-29 11:44:13,690 INFO | /app/rest/controller/userdetails | f80fdc1f-8123-3932-a405

问题 As I read in akka specification it supports mdc in actors. E.g. I can put unic infomation in mdc and then use it in actor. But what about futures? Does akka provide any guaranties that a future which is initiated in actor will have the same mdc? Also what about message that send to other actors - is MDC copied by default? Note For me it looks very strange, that I can use MDC only inside one actor code. 回答1: They could but they actually don't. When you call members of LoggingAdapter you

问题 I'm wanting to know how to log things such as the Job Name and Execution ID using MCD in Spring Batch. Here's some code: bootstrap.properties this file has a list of items I currently log, and I've added execId as the 3rd element here. logging.pattern.level=%5p [%X{X-B3-TraceId:-},%X{sessionId:-},%X{execId:-},%X{program:-},%X{mainframeId:-}] spring.application.name=mcc spring.profiles.active=globals,local,local-override MCC Application this file has my main method.
