我正在尝试创建一个注入解析器。我有一个数据类：

public class MyData {
    ...
}

我有以下注释：

@Target({ElementType.FIELD, ElementType.PARAMETER})
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface MyDataInject {
}

我的注入解析器如下所示：

public class MyDataInjectionResolver extends ParamInjectionResolver<MyDataInject> {
    public MyDataInjectionResolver () {
        super(MyDataValueFactoryProvider.class);
    }

    @Singleton
    public static class MyDataValueFactoryProvider extends AbstractValueFactoryProvider {
        @Inject
        public MyDataValueFactoryProvider(MultivaluedParameterExtractorProvider provider, ServiceLocator locator) {
            super(provider, locator, Parameter.Source.UNKNOWN);
        }

        @Override
        protected Factory<?> createValueFactory(Parameter parameter) {
            System.out.println(parameter.getRawType());
            System.out.println(Arrays.toString(parameter.getAnnotations()));
            System.out.println("------------------------------------------------------------------");
            System.out.println();

            ... create factory and return ...
        }
    }
}

我绑定如下：

bind(MyDataValueFactoryProvider.class).to(ValueFactoryProvider.class).in(Singleton.class);
bind(MyDataInjectionResolver.class).to(new TypeLiteral<InjectionResolver<MyDataInject>>() {}).in(Singleton.class);

为了简洁起见，我省略了实际工厂的实现。一切正常，但我注意到一些我无法解释的行为。我正在使用以下 JAX-RS 资源进行测试：

@Path("test")
public class Test …
