java - Jersey 2 请求过滤器在此代码中不起作用

Question

我已经使用 Jersey 2 实现了注释，但不知何故代码没有达到这一点。

这些是我的类(class):

安全

import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import static java.lang.annotation.RetentionPolicy.RUNTIME;
import java.lang.annotation.Target;

import javax.ws.rs.NameBinding;

@NameBinding
@Retention(RUNTIME)
@Target({ElementType.METHOD, ElementType.TYPE})
public @interface Secured { }

安全实现:

import javax.annotation.Priority;
import javax.ws.rs.Priorities;
import javax.ws.rs.WebApplicationException;
import javax.ws.rs.container.ContainerRequestContext;
import javax.ws.rs.container.ContainerRequestFilter;
import javax.ws.rs.core.Response.Status;
import javax.ws.rs.ext.Provider;

@Secured
@Provider
@Priority(Priorities.AUTHENTICATION)
public class SecureImplementation implements ContainerRequestFilter
{
  @Override
    public void filter(ContainerRequestContext requestContext) throws 
  IOException {
        System.out.println("Inside Something");
        throw new WebApplicationException(Status.UNAUTHORIZED);
}
}

测试类

@Path("/checkClass")
public class TestingClass{

    @Secured
    @Path("/checkFilter")
    @POST
    @Produces(MediaType.APPLICATION_JSON)
    @Consumes(MediaType.APPLICATION_JSON)
    public Map<String, String> testing(Input input)
            throws Exception {
        Map<String, Object> responseMap = new HashMap<String, Object>();
        responseMap.put("result","Success");
        return responseMap;
   }
  }

它给了我一个响应，而不是给我一个 401 错误。那么，我在这里做错了什么？

通常 TestingClass 应与过滤器一起在应用程序类中注册，例如:

@ApplicationPath("checkClass")
public class MyApplication extends ResourceConfig {

    public MyApplication () {
        register(TestingClass.class);
        register(SecureImplementation.class);
    }
}


@Path("/checkFilter")
public class TestingClass{

    @Secured
    @POST
    @Produces(MediaType.APPLICATION_JSON)
    @Consumes(MediaType.APPLICATION_JSON)
    public Map<String, String> testing(Input input)
