英文:
@Inject not working for AuthFilter in Guice + Jersey2
问题
我正在尝试使用Guice将依赖项注入到我的自定义AuthFilter中，该AuthFilter实现了ContainerRequestFilter接口。
我的目标是创建一个应用于特定资源的AuthenticationFilter。@Inject在资源类方面运行良好，但在AuthFilter类方面不起作用。
认证过滤器如下所示：
public class MyApiAuthFilter implements ContainerRequestFilter {
@Inject
private InjectableResource injectableresource;
@Override
public void filter(ContainerRequestContext request) {
// 过滤逻辑
}
}
这是我注册authfilter和guice-hk2桥接的方式：
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。我已经使用@ImplementedBy注解对InjectableResourceInterface进行了注解。
我遇到了启动错误。错误日志如下：
WARN 已检测到以下警告：

是否有解决方法，使得@Inject在AuthFilter中也能工作？
英文:
I'm attempting to use Guice to inject dependencies into my custom AuthFilter which implements ContainerRequestFilter.
My aim is to have an AuthenticationFilter that is applied to specific Resource. @Inject is working fine for the Resource classes but not for the Authfilter class.
Authetication Filter looks like
public class MyApiAuthFilter implements ContainerRequestFilter {
@Inject
private InjectableResource injectableresource;
@Override
public void filter(ContainerRequestContext request) {
//Filter Logic
}
}
This is how I register the authfilter and guice-hk2 bridge
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 is an implementation class for InjectableResourceInterface. I have annotated InjectableResourceInterface with @ImplementedBy annotation.
I am getting startup error. Error log:

Any workaround so that @Inject also works for the AuthFilter?
