log4j

I need some direction in configuring the log format in Tomcat 7. I am relatively new at logging configurations so please excuse humor this questions if it seems a bit basic... Using the standard logging in Tomcat configured in logging.properties displays a log in the format of: Jun 6, 2011 9:27:00 AM com.class.Control_WS callWebService INFO: Response received from Control_WS:[Y] I would like to customize these logs to compress on to one line as well as expanding the date format to include milliseconds. Example: [2011-05-04T11:37:00.037|INFO|javax.enterprise.system.stream.out|Response recieved

SpringBoot系列之使用切换log4j日志框架 ok，在pom文件右键->Diagrams->show Dependencies....，如图，找到spring-boot-starter-logging，可以看到SpringBoot的日志实现默认依赖与logback，ok，如果你对这些知识不是很理解的，建议先看我Springboot专栏的日志系列博客： https://smilenicky.blog.csdn.net/category_9195353.html 本博客要实现的是切换默认日志框架为log4j，当然是不建议这样做的，因为log4j有性能问题，所以其作者才开发了logback，不过作为学习的话，还是可以学一下怎么切换Springboot默认的日志框架 先去 slf4j官网 拿一张图：图示，切换日志框架，为了避免冲突，一般都是先排除日志框架的实现jar，然后再将之前博客提到的偷梁换柱jar，比如log4j-to-slf4j.jar等等先排除，然后再引入对应的日志实现jar，如图所示的slf4j-log4j12.jar，因为本博客并非入门教程，所以学习之前请先参考我之前Springboot日志方面的博客，再来学习 ok，基于slf4j官方提供的知识，我们就可以实践了，首先选中logback-classic.jar(logback实现jar)、log4j-to-slf4j

I have this code with log4j, I don't use any kind of configuration files static Logger logger = Logger.getLogger(Application.class); ... Appender ap = new NTEventLogAppender(); SimpleLayout layout = new SimpleLayout(); Appender fp = null; try { fp = new FileAppender(layout, "output.txt"); } catch (IOException e) { e.printStackTrace(); } logger.addAppender(ap); logger.addAppender(fp); logger.info("info"); can anybody show me how can I do the same thing with logback Why is it that you don't use configuration files? Is is because you change the logging configuration at runtime? Unless you have a

一、需要3.0以上版本的redis 二、redis-cli实现发布订阅 先开启一个redis-cli（S1），并监听着china这个channel subcribe china 此时A1处于监听状态 然后再开启一个redis-cli(P1)，并向china这个channel发布helloWorld消息 publish china helloWorld 这是我们会发现A1监听到了这个helloWorld消息 同样，我们开启多个监听窗口，这时我们会发现，他们都可以收到这个helloWorld消息，这和MQ中间件中的发布订阅相同，只有在发布的时刻监听的监听者可以消费到这条消息。 三、Jedis实现发布订阅 <dependency> <groupId>redis.clients</groupId> <artifactId>jedis</artifactId> <version>2.8.0</version> </dependency> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.17</version> </dependency> Jedis中的JedisPubSub抽象类提供了订阅和取消的功能。想处理订阅和取消订阅某些channel的相关事件

I use log4j for logging in my project. Here is it's sample setup: public class MyClass { private final Logger logger = Logger.getLogger(MyClass.class); public MyClass() { BasicConfigurator.configure(); Logger.getLogger(MyClass.class).setLevel(Level.INFO); } ... } The problem is that on each next logger call it duplicates log messages (I mean on first call there is only 1 message, on second call there are 2 same messages, then there are 3 of them and so on). It seems that each time new logger's instance is created and used with all old instances. How to avoid this problem? Thanks. UPP. Tried to

I'd like to start using Chainsaw v2. There is almost no information about it. I've found only this , but links cannot be opened, so it isn't clear.

I need to get my Java application writing logging to a Graylog2 server. The application uses a log4j configuration. Several things I have tried to get the logging writing to the Graylog2 server, the things I got working was sending a test message directly to the server, as shown here (first example). Yet, when I write an appender and attach it to the root logger, I always get this error message the first time a log event is to be fired: log4j:ERROR Could not send GELF message Nothing then happens on the Graylog2 server side. The appender I try to get working: <appender name="graylog2" class=
