使用Jersey和@ApplicationPath批注加载资源 [英] Loading resources using Jersey and @ApplicationPath annotation

问题描述

我正在尝试在不使用web.xml的情况下将基本的jersey restful服务部署到Tomcat7:

I'm trying to deploy a basic jersey restful service to Tomcat7 without web.xml:

 @WebServlet(loadOnStartup=1)
 @ApplicationPath("resources")
 @Path("/mypath/{name}")
 public class MyResource extends Application {

 @Override
 public Set<Class<?>> getClasses() {
     Set<Class<?>> s = new HashSet<Class<?>>();
     s.add(MyResource.class);
     return s;
 }

 @GET
 @Consumes("text/plain")
 @Produces("text/plain")
 public String getWelcome(@PathParam(value = "name") String name) {
     return "Welcome to jax-rs " + name;
 }
}

在尝试访问时，系统显示404错误:/myapplication/resources/mypath/sample .

I'm presented with a 404 when trying to access: /myapplication/resources/mypath/sample.

我可以使用@WebServlet批注来部署servlet，因此，这与将没有web.xml的servlet加载到Tomcat7中无关.

I can deploy a servlet using the @WebServlet annotation, so this has nothing to do with the loading of servlets without web.xml into Tomcat7.

通过阅读Jersey的文档，运行时应扫描扩展Application的类并执行getClasses()，并加载所有根资源.

From reading the documentation for Jersey, the runtime should scan for classes extending Application and execute getClasses(), loading all root resources.

推荐答案

您正在使用哪个版本的Jersey?尝试将应用程序和资源分为两个类.绝对删除@WebServlet批注. IE.有一个扩展了Application的类，该应用程序用@ApplicationPath注释，另一个类是用@Path注释.

Which version of Jersey are you using? Try splitting application and resource in two classes. Definitely remove @WebServlet annotation. I.e. have one class extending Application annotated with @ApplicationPath and another class annotated with @Path.

确保您的WAR文件中包含jersey-servlet.jar.

Make sure that jersey-servlet.jar is included in your WAR file.
