Jersey映射混淆

Question

谁能用通俗易懂的英语解释一下这是如何工作的(或者至少为什么我的结构不能)？我希望泽西servlet资源中有一个名为ExportLicenseInfo的函数(我称之为ExportResource )来映射到http://example.com/myApp/export/software_licenses.{year}-{month}.{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( ... ) {
    ...
    }

当我试图访问资源时，我会得到404。泽西岛追踪日志：

尝试像下面这样映射：

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