openkad项目有问题,但可能是向导/环境问题:

要点是代码使用Guice来:

@Provides
@Singleton
@Named("openkad.rnd")
Random provideRandom(@Named("openkad.seed") final long seed) {
        return seed == 0 ? new Random() : new Random(seed);
    }


但是,@ Singleton和@Named(“ openkad.rnd”)都被编译器标记为不正确的放置位置。

显然是正确的,因为命名的注释针对的是字段而不是方法:

/**
 * Annotates named things.
 *
 * @author [email protected] (Bob Lee)
 */
@Retention(RUNTIME)
@Target({ ElementType.FIELD, ElementType.PARAMETER })
@BindingAnnotation
public @interface Named {
  String value();
}


重新创建:


使用针对各种运行时的JDK 1.6或1.8在eclipse中创建Java项目
通过pom包含依赖项(尝试了第1至第4种方法)
使用源或openkad r60 jar文件运行单元测试(https://code.google.com/p/openkad/


什么是预期的输出?你看到了什么呢?

所有UT的成功,但是我看到了:

谢谢

最佳答案

塔维安·巴恩斯(Tavian Barnes)的建议奏效了。
