How to enable a custom log4j with Jboss AS 7.1

由 半城伤御伤魂 提交于 2019-12-07 06:10:34
问题 I tried several options. But anything didn't work for me. Previously I used the same log4j.xml (simple common config) with Tomcat 6,7 and I could able to control the root logging and the application logging with updating the log4j.xml. When I deploy the same project with JBoss AS 7.1, It only gives me INFO level logging and my log4j.xml doesn't work at all. Sometime this can be fixed by updating some configuration files inside the JBoss server, but I like to know if there a portable way to do

问题 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).

XWiki默认是使用SLF4J和Logback来管理日志。Logback配置文件位于WEB-INF/classes/logback.xml。 XWIki classpath下面第三方包生成的日志通过Logback配置文件的定义可以自动找到自己输出方式。由于原先使用的是Apache Commons Logging（JCL），Log4J作为日志框架，为了与SLF4J共存，通过SLF4J桥接器可以保证，既 log4j-over-slf4j-*.jar和jcl-over-slf4j-*.jar。 默认情况下，XWiki日志只输出到控制台。控制台内容是否被Servlet容器捕获取决于你使用的servlet容器。例如，部署在unix的tomcat能捕获标准输出并把信息输出到tomcat/logs/catalina.out。 配置日志 有多种方法配置日志。 提出以下3种方法中，只有手动的方法是在服务器重新启动后也是持续有效的。所以，如果你的服务器可能会重新启动并且你想要在重启后保留修改的日志配置，唯一的方法是将它们添加到logback.xml。 手动 只需编辑的logback配置文件（logback.xml位于web应用程序WEB-INF/classes文件夹下），然后重新启动Servlet容器使其生效。 使用Log应用程序 XWiki 4.2开始可以在wiki的管理界面使用 Logging

问题 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
