java - @Inject 不适用于 Guice + Jersey2 中的 AuthFilter

问题描述

我正在尝试使用 Guice 将依赖项注入到实现 ContainerRequestFilter 的自定义 AuthFilter 中。我的目标是拥有一个应用于特定资源的 AuthenticationFilter。@Inject 适用于 Resource 类，但不适用于 Authfilter 类。

身份验证过滤器看起来像

public class MyApiAuthFilter implements ContainerRequestFilter {
    @Inject
    private InjectableResource injectableresource;
    @Override
    public void filter(ContainerRequestContext request) {
     //Filter Logic
   }
}

这就是我注册 authfilter 和 guice-hk2 网桥的方式

public class MyApplication extends ResourceConfig {

    @Inject
    public MyApplication(ServiceLocator serviceLocator) {
        register(MyApiAuthFilter.class);

        register(new ContainerLifecycleListener() {
            public void onStartup(Container container) {
                ServletContainer servletContainer = (ServletContainer)container;
                GuiceBridge.getGuiceBridge().initializeGuiceBridge(serviceLocator);
                GuiceIntoHK2Bridge guiceBridge = serviceLocator.getService(GuiceIntoHK2Bridge.class);
                Injector injector = (Injector) servletContainer.getServletContext().getAttribute(Injector.class.getName());
                guiceBridge.bridgeGuiceInjector(injector);
            }
            public void onReload(Container container) {

            }
            public void onShutdown(Container container) {
            }
        });

    }

InjectableResource 是 InjectableResourceInterface 的实现类。我用 @ImplementedBy 注释对 InjectableResourceInterface 进行了注释。

我收到启动错误。错误日志：

任何解决方法使@Inject 也适用于 AuthFilter？
