如何在Web应用程序中为jar接收正确的类加载器？

Question

I have application mywebapp. This application depends from myjarconfig.jar. File myjarconfig.jar contains file config.xml. To take resource I use code:

InputStream confStream = ClassLoader.class.getResourceAsStream("/conf/config.xml");

But I always receive null. When I look in debugger - I see that ClassLoader is mywebapp. Why it is not jar file? What need to check? Thanks.

如果您的jar位于WEB-INF / lib，容器的类路径，引导类路径等位置，则应使用

Thread.currentThread().getContextClassLoader().getResourceAsStream("/conf/config.xml")
