有一个openkad项目的问题，但可能是一个guice / environment问题：
gist是代码使用Guice来：
@Provides
@Singleton
@Named("openkad.rnd")
Random provideRandom(@Named("openkad.seed") final long seed) {
return seed == 0 ? new Random() : new Random(seed);
}
然而@Singleton和@Named（“openkad.rnd”）都被编译器标记为不正确的放置。
并且显然是正确的，因为命名注释以字段为目标，而不是方法：
/**
* Annotates named things.
*
* @author crazybob@google.com (Bob Lee)
*/
@Retention(RUNTIME)
@Target({ ElementType.FIELD, ElementType.PARAMETER })
@BindingAnnotation
public @interface Named {
String value();
}
重新创建：
预期产量是多少？你怎么看？
所有UT的成功，但我看到了这一点：
