使用Jersey资源的HK2 MethodInterceptor

Question

如何设置aop MethodInterceptor与Jersey资源一起工作?

以下是我尝试过的，遵循这个文档:

步骤1 - InterceptionService

public class MyInterceptionService implements InterceptionService
{
    private final Provider<AuthFilter> authFilterProvider;
    @Inject
    public HK2MethodInterceptionService(Provider<AuthFilter> authFilterProvider)
    {
        this.authFilterProvider = authFilterProvider;
    }
    /**
     * Match any class.
     */
    @Override
    public Filter getDescriptorFilter()
    {
        return BuilderHelper.allFilter();
    }
    /**
     * Intercept all Jersey resource methods for security.
     */
    @Override
    @Nullable
    public List<MethodInterceptor> getMethodInterceptors(final Method method)
    {
        // don't intercept methods with PermitAll
        if (method.isAnnotationPresent(PermitAll.class))
        {
            return null;
        }
        return Collections.singletonList(new MethodInterceptor()
        {
            @Override
            public Object invoke(MethodInvocation methodInvocation) throws Throwable
            {
                if (!authFilterProvider.get().isAllowed(method))
                {
                    throw new ForbiddenException();
                }
                return methodInvocation.proceed();
            }
        });
    }
    /**
     * No constructor interception.
     */
    @Override
    @Nullable
    public List<ConstructorInterceptor> getConstructorInterceptors(Constructor<?> constructor)
    {
        return null;
    }
}

步骤2 -注册服务

public class MyResourceConfig extends ResourceConfig
{
    public MyResourceConfig()
    {
        packages("package.with.my.resources");
        // UPDATE: answer is remove this line
        register(MyInterceptionService.class);
        register(new AbstractBinder()
        {
            @Override
            protected void configure()
            {
                bind(AuthFilter.class).to(AuthFilter.class).in(Singleton.class);
                // UPDATE: answer is add the following line
                // bind(MyInterceptionService.class).to(InterceptionService.class).in(Singleton.class);
            }
        });
    }
}

然而，这似乎不起作用，因为我的资源方法都没有被拦截。这是因为我用@ManagedAsync和我所有的资源吗?什么好主意吗?

另外，请不要建议使用ContainerRequestFilter。请参阅这个问题，了解为什么我不能使用一个来处理安全性。

我认为，而不是调用register(MyInterceptionService.class)你可能要添加到你的configure()语句:

bind(MyInterceptionService.class).to(InterceptionService.class).in(Singleton.class)

我不确定它是否会起作用，因为我自己没有尝试过，所以你的结果可能会有所不同lol
