log4j和weblogic:重复的日志消息 [英] log4j and weblogic: duplicate log messages
问题描述
我使用log4j登录我的项目。以下是它的示例设置:
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);
}
...
}
问题在于,在每次下一次记录器调用时,它都会复制日志消息(我的意思是在第一次呼叫时只有1条消息,在第二次呼叫时有2条相同的消息,然后有3条消息,依此类推)。似乎每次创建新记录器的实例并与所有旧实例一起使用。
如何避免这个问题?
谢谢。
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。试图让它静止,但它无论如何都不起作用。我仍然收到多条日志消息。有任何想法吗?可能是一些Weblogic特定的东西?
UPP. Tried to make it static,but it doesn't work anyway. I still get multiple log messages. Any ideas? Probably some Weblogic specific stuff?
推荐答案
使记录器静态
private static final Logger logger = Logger.getLogger(MyClass.class);
这里的关键是创建一个 Logger
对于每个类,而不是每个实例。
The key here is to create a Logger
for each class, and not for each instance.
