java - Jersey servlet 映射困惑

Question

有人可以用简单的英语解释它是如何工作的(或者至少为什么我的结构不能)？我希望在 Jersey servlet 资源(我将其称为 ExportResource)中有一个名为 ExportLicenseInfo 的函数，以映射到 http://example.com/myApp/export/software_licenses.{year}-{月}.{format}，例如:http://example.com/myApp/export/software_licenses_2013-10.csv

web.xml 中的 Servlet 配置:

<servlet>
    <servlet-name>ExportServlet</servlet-name>
    <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>

    <init-param>
        <param-name>javax.ws.rs.Application</param-name>
        <param-value>com.mycompany.app.ExportApplication</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

我在 web.xml 中的 servlet 映射:

<servlet-mapping>
    <servlet-name>ExportServlet</servlet-name>
    <url-pattern>/export</url-pattern>
</servlet-mapping>

我的带有 @Path 注释的代码:

@Path("/export")
public class ExportResource {

    ...

    @GET
    @Produces({"text/csv", "application/json"})
    @Path("/software_licenses_{year: [0-9][0-9][0-9][0-9]}-{month: [0-1][0-9]}.{format}")
    public String ExportLicenseInfo( ... ) {
    ...
    }

当我尝试访问资源时，我收到 404.Jersey 跟踪日志:

尝试像这样映射 Jersey servlet:

<servlet-mapping>
<servlet-name>ExportServlet</servlet-name>
<url-pattern>/export/*</url-pattern>
</servlet-mapping>
