来自servlet spec , section 10.5 Directory structure (我强调):

A special directory exists within the application hierarchy named “WEB-INF”. This directory contains all things related to the application that aren’t in the document root of the application. Most of the WEB-INF node is not part of the public document tree of the application. Except for static resources and JSPs packaged in the META- INF/resources of a JAR file that resides in the WEB-INF/lib directory, no other files contained in the WEB-INF directory may be served directly to a client by the container. However, the contents of the WEB-INF directory are visible to servlet code using the getResource and getResourceAsStream method calls on the ServletContext, and may be exposed using the RequestDispatcher calls...

因此，您的体验是“设计使然”的。如果您需要通过 HTTP 请求它们，请将您的资源放在别处。
