Serving static files with Jersey 2
提问by mbcrute
I'm new to Jersey and servlets in general so hopefully I'm just missing something simple...
我是泽西岛和 servlets 的新手，所以希望我只是错过了一些简单的东西......
I've got a Jersey app (v2.13) up and running using Guice (3.0) for dependency injection along with some static files in src/main/webapp. If I map my Jersey servlet to anything other than /* and make a request for a static file in the webapp folder, it gets served up no problem. If I map my Jersey servlet to the root, any request for a static file is met with a 404.
我有一个 Jersey 应用程序 (v2.13) 启动并运行，使用 Guice (3.0) 进行依赖注入以及 src/main/webapp 中的一些静态文件。如果我将 Jersey servlet 映射到 /* 以外的任何内容，并请求 webapp 文件夹中的静态文件，则它不会出现问题。如果我将 Jersey servlet 映射到根目录，则任何对静态文件的请求都会遇到 404。
I'd really prefer to have the Jersey servlet mapped to the root but I also need to be able to serve static content. Is there any way to accomplish this? Perhaps to map the Jersey servlet to the root but ignore requests for /assets/* or something similar?
我真的更喜欢将 Jersey servlet 映射到根目录，但我还需要能够提供静态内容。有什么办法可以做到这一点吗？也许将 Jersey servlet 映射到根目录，但忽略对 /assets/* 或类似内容的请求？
Here is my web.xml:
这是我的 web.xml：
<filter>
<filter-name>guice-filter</filter-name>
<filter-class>com.google.inject.servlet.GuiceFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>guice-filter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<listener>
<listener-class>com.example.MyGuiceServletContextListener</listener-class>
</listener>
<servlet>
<servlet-name>Jersey Web Application</servlet-name>
<servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
<init-param>
<param-name>javax.ws.rs.Application</param-name>
<param-value>com.example.MyResourceConfig</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>Jersey Web Application</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>

I was pointed to thisquestion and got my answer. Basically I just need to change the Jersey servlet to a filter and supply a static content regex as an init param. Now I have my servlet mounted at the root and my static files are getting served up just like I wanted.
我被指向这个问题并得到了我的答案。基本上我只需要将 Jersey servlet 更改为过滤器并提供静态内容正则表达式作为 init 参数。现在我将我的 servlet 安装在根目录下，并且我的静态文件正像我想要的那样提供服务。
