如何使用Jersey将依赖项注入资源？

@Path("example")
public class ExampleResource {
    @Inject
    private Dependency dependency;

    @GET
    public String getExample() {
        return dependency.doSomething();
    }
}

@Provider
public class DependencyProvider implements InjectableProvider<Inject, Type> {
    @Override
    public ComponentScope getScope() {
        return ComponentScope.Singleton;
    }

    @Override
    public Injectable<?> getInjectable(ComponentContext ic, Inject a, Type c) {
        if (c.equals(Dependency.class)) {
            return new Injectable<Dependency>() {
                @Override
                public Dependency getValue() {
                    return new Dependency();
                }
            };
        }
        return null;
    }
}

public class Dependency {
    public String doSomething() {
        return "Hello, Jersey!";
    }
}

public class ApplicationConfig extends ResourceConfig {
    public ApplicationConfig() {
        register(ExampleResource.class);
        register(DependencyProvider.class);
    }
}
