Question

我有以下示例球衣应用程序，其中我使用HK2拦截具有自定义注释的休息端点以验证标头。但似乎REST端点永远不会被拦截

调试时我可以看到MyInterceptionService类没有扫描端点类。

@Target({ElementType.METHOD, ElementType.TYPE})
@Retention(RetentionPolicy.RUNTIME)
public  @interface CustomInterceptor {
}

@Path("/")
public class RestEndpoint{

    @GET
    @Path("intercepted")
    @Produces({MediaType.APPLICATION_JSON})
    @Consumes({MediaType.APPLICATION_JSON})
    @ManagedAsync
    @CustomInterceptor
    public String getIntercepted() {
        return "ServerResource: Intercepted method invoked\n";
    }
}


@ApplicationPath("/")
public class Application extends ResourceConfig {
 public Application() {
        packages("com.example");
        register(new MyInterceptionBinder());
    }
}

public class MyInterceptionBinder extends AbstractBinder {
    @Override
    protected void configure() {
        bind(MyInterceptionService.class)
                .to(org.glassfish.hk2.api.InterceptionService.class)
                .in(Singleton.class);
    }
}


public class MyInterceptionService implements InterceptionService {
    private final List<MethodInterceptor> interceptors = Collections.singletonList(new MyInterceptor());

    @Override
    public Filter getDescriptorFilter() {
       return BuilderHelper.allFilter();
    }

    @Override
    public List<MethodInterceptor> getMethodInterceptors(Method method) {
        System.err.println("----"+method.getDeclaringClass());
        if(method.isAnnotationPresent(CustomInterceptor.class)) {
            return interceptors;
        }
    }

    @Override
    public List<ConstructorInterceptor> getConstructorInterceptors(Constructor<?> constructor) {
        return null;
    }
}



public class MyInterceptor implements MethodInterceptor {
    @Override
    public Object invoke(MethodInvocation invocation) throws Throwable { 
        return invocation.proceed();
    }
}

感谢任何建议。

HK2 Custom InterceptionService拦截REST端点不起作用
