Loading resources using Jersey and @ApplicationPath annotation
提问by wulfgarpro
I'm trying to deploy a basic jersey restful service to Tomcat7 without web.xml:
我正在尝试在没有 web.xml 的情况下向 Tomcat7 部署一个基本的 jersey restful 服务：
@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;
}
}
I'm presented with a 404 when trying to access: /myapplication/resources/mypath/sample.
我在尝试访问时看到 404：/myapplication/resources/mypath/sample。
I can deploy a servlet using the @WebServletannotation, so this has nothing to do with the loading of servlets without web.xml into Tomcat7.
我可以使用@WebServlet注释部署一个servlet ，所以这与将没有web.xml的servlet加载到Tomcat7中无关。
From reading the documentation for Jersey, the runtime should scan for classes extending Applicationand execute getClasses(), loading all root resources.
通过阅读 Jersey 的文档，运行时应该扫描扩展Application和执行的类getClasses()，加载所有根资源。

Which version of Jersey are you using? Try splitting application and resource in two classes. Definitely remove @WebServletannotation. I.e. have one class extending Application annotated with @ApplicationPathand another class annotated with @Path.
您使用的是哪个版本的 Jersey？尝试将应用程序和资源分成两个类。绝对删除@WebServlet注释。即有一个扩展应用程序的@ApplicationPath类用注释，另一个类用注释@Path。
EDIT: Make sure that jersey-servlet.jaris included in your WAR file.
编辑：确保jersey-servlet.jar包含在您的 WAR 文件中。
