如何将自定义日志处理程序添加到Google App Engine? [英] How to add custom log handler to Google App Engine?
问题描述
我正在尝试向我的Java应用程序添加自定义日志处理程序.我实现了一个InnerLogger类,该类扩展了java.util.Logging.Handler类.并在我的logging.properties中声明为处理程序:
I am trying to add a custom log handler to my java application. I have implemented a InnerLogger class that extends java.util.Logging.Handler class. And in my logging.properties declared as a handler:
handlers:com.mycompany.util.InnerLogger
但是当我启动开发服务器时,出现以下错误:
But when I launch the development sever, I got the following error:
Can't load log handler "com.mycompany.util.InnerLogger"
java.lang.ClassNotFoundException: com.mycompany.util.InnerLogger
我可以将自定义处理程序一个一个地添加到记录器中,但是我只是想知道是否有一种方法可以将其添加到所有记录器中.
I can add my custom handler to loggers one by one ,but I just wondering is there a way to add it to all loggers.
谢谢
推荐答案
在我的应用程序初始化时,我能够将Handler
添加到根Logger
中.您可以将此代码放入预热任务或Servlet过滤器中.
I was able to add a Handler
to the root Logger
when my application initializes. You can put this code in a warmup task or servlet filter.
private static Logger LOG;
...
LOG = Logger.getLogger("");
LOG.addHandler(myCustomHandler);
它不像使用logging.properties那样优雅,但是在GAE上运行时,这是一个适当的解决方法.
Its not as graceful as using logging.properties, but it is an adequate workaround when running on GAE.
