java - HK2 MethodInterceptor 与 Jersey 资源

Question

如何设置 aop MethodInterceptor 来处理 Jersey 资源？

这是我在 this 之后尝试过的文档:

第 1 步 - 拦截服务

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;
    }
}

第 2 步 - 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);
            }
        });
    }
}

但是这似乎不起作用，因为我的资源方法都没有被拦截。这可能是因为我对所有资源都使用了 @ManagedAsync 吗？有什么想法吗？

此外，请不要建议 ContainerRequestFilter。参见 this question为什么我不能用一个来处理安全问题。

我认为与其调用 register(MyInterceptionService.class)，不如在 configure() 语句中添加:

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

我不确定它是否有效，因为我自己还没有尝试过，所以您的结果可能会有所不同，哈哈
