是否可以在log4j中更改软件包的日志级别? [英] Is it possible to change the log level of a package in log4j?

问题描述

当前，我有一个库，该库将某些信息记录为ERROR.如果我这样更改log4j设置:

Currently I have a library that is logging certain information as ERROR. If I change my log4j settings like this:

log4j.logger.com.company.theirpackage.foo=OFF

将完全禁用该库的日志记录.但是，我真正想要的是仍然查看信息，但是将其记录在WARN或INFO级别.换句话说，当该特定代码调用log.error()时，我希望它看起来像是调用了log.warn()或log.info()一样.

that will completely disable the library's logging altogether. However, what I'd really like is to still see the information, but have it logged at a WARN or INFO level. In other words, when that particular code calls log.error(), I want it to be as if they had called log.warn() or log.info() instead.

有没有办法用log4j做到这一点?

Is there a way to do this with log4j?

推荐答案

不是直接的，但是您可以编写一个自定义的附加程序来拦截调用，检查级别，然后将其打印到所需的任何级别.或者，您可以进行一些面向方面的编程，并拦截/更改其调用.

Not directly, but you could write a custom appender that intercepts the calls, checks the levels, and then prints them at whatever level you want. Or, you could do some aspect oriented programming and intercept/change their calls.

但是为什么要更改他们登录的级别?

But why would you want to change the level they log it at?
