Specify only some packages to have debug output
提问by Smolda
I want to log some behavior of my web application which also implements hibernate, spring and so on. When I tried to implement log4j logger from apache I had some troubles.
我想记录我的 Web 应用程序的一些行为，它也实现了休眠、弹簧等。当我尝试从 apache 实现 log4j 记录器时，我遇到了一些麻烦。
When I turn on logger it is also debugging hibernate and spring which I don't want. I tried to configure properties file to the specify the package of my project but it does not work.
当我打开记录器时，它也在调试我不想要的休眠和弹簧。我试图配置属性文件来指定我的项目包，但它不起作用。
Here is my code of property file:
这是我的属性文件代码：
log4j.rootCategory=ERROR, O
log4j.category.com.my.package= DEBUG, FILE, O
log4j.appender.FILE=org.apache.log4j.RollingFileAppender
log4j.appender.FILE.File=log/logger.log
log4j.appender.O=org.apache.log4j.ConsoleAppender
.... and some layout
It works when I switch rootCategory = DEBUGbut it is also debugging the hibernate and spring as I said.
它在我切换时工作，rootCategory = DEBUG但正如我所说的，它也在调试休眠和弹簧。

Yes, you have to specfiy the log level per package:
是的，您必须指定每个包的日志级别：
log4j.logger.org.hibernate=info
log4j.logger.org.springframework=info
log4j.logger.com.yourapplication=debug
Note that you should switch from categories (obsolete) to loggers. So log4j.rootLogger=...
请注意，您应该从类别（过时）切换到记录器。所以log4j.rootLogger=...

You would need to know the name of the loggers that are actually writing stuff... The simplest way is to set the root category to error:
您需要知道实际编写内容的记录器的名称...最简单的方法是将根类别设置为错误：
log4j.rootCategory=ERROR, 0
Then set the level for your logs accordingly:
然后相应地设置日志的级别：
log4j.com.your.package=DEBUG...
Setting the rootCategoryto DEBUGwill turn everythingto DEBUG, unless you specifically configure a logger otherwise.
设置rootCategorytoDEBUG会将所有内容变为DEBUG，除非您另外专门配置了记录器。
B.T.W, this is NOT a hibernate issue, this is related to how you are configuring your logger.
顺便说一句，这不是休眠问题，这与您配置记录器的方式有关。
