如何使更具体的urlPattern覆盖带有注释的更广泛的模式 [英] How to make more specific urlPattern override broader pattern with annotations

问题描述

我目前有一个带有以下注释的主控制器servlet:

I currently have a main controller servlet with the following annotation:

@WebServlet(name="ControllerServlet", urlPatterns={"/", "/home"})

在我的项目中，我的.jsp文件引用的/resources目录下有.js和.css文件，并且链接已发送到不需要的主控制器.我制作了第二个servlet，以处理带有nn批注的.js .css文件:

I have .js and .css files under the /resources dir in my project that my .jsp files reference and the links are getting sent to my main controller which I don't want. I made a second servlet to handle the .js .css files with nn annotation of:

@WevServlet(name="ResourceServlet", urlPatterns={"/resources"})

希望它可以接收来自我的.jsp文件的请求，但ControllerServlet仍可以接收它们.如何使/resources网址定向到我的ResourceServlet?

hoping that it would pick up the requests coming from my .jsp files but ControllerServlet is still picking them up. How can I make /resources urls get directed to my ResourceServlet?

推荐答案

URL模式/与其他映射不匹配的任何内容匹配.如果有

The url pattern / matches anything that isn't matched by the other mappings. If you have

@WebServlet(name="ResourceServlet", urlPatterns={"/resources"})

然后请求，例如localhost:8080/context/resources将由您的ResourceServlet处理，但不会发送给localhost:8080/context/resources/somescript.js的请求，因为它与ResourceServlet的网址格式不匹配.因此，ControllerServlet将对其进行处理.

then a request to, eg. localhost:8080/context/resources will be handled by your ResourceServlet, but a request to localhost:8080/context/resources/somescript.js won't because it doesn't match ResourceServlet's url pattern. Therefore, ControllerServlet will handle it.

您需要将ResourceServlet映射更改为

@WebServlet(name="ResourceServlet", urlPatterns={"/resources/*"})
