如何将协作者连接到Jersey资源？

Question

我有一个方法来启动我的应用程序:

public void start() throws IOException {
    final Map<String, String> initParams = new HashMap<String, String>();
    initParams.put("com.sun.jersey.config.property.packages", "com.example");
    threadSelector = GrizzlyWebContainerFactory.create(baseUri, initParams);
}

我有一个Jersey资源类:

@Path("/notification")
public class NotificationResource {
    // HOW DO I INJECT THIS GUY?
    private MySampleCollabolator  mySampleCollabolator;    

    @POST
    public void create() {
        System.out.println("Hello world"); 
    }
}

处理依赖项的正确方法是什么？我希望我的资源与其他对象进行通信,如何将它们连接在一起？

您可以实现InjectableProvider.例如:

@Provider
public class FooProvider
    implements InjectableProvider<Resource, Type> {

    public ComponentScope getScope() {
        return ComponentScope.PerRequest;
    }

    public Injectable getInjectable(ComponentContext ic, Resource resource, Type type) {
        return new Injectable() {
            public Object getValue() {
                return new Foo();
            }
        };
    }
}

然后在资源中注释字段:

@Resource私人Foo foo;
