                 bind(Car.class).annotatedWith(Red.class).to(Car.class);

                 You cannot solve this by

                 or
                 bind(Transmission.class).to(AutomaticTransmission.class).ifParentAnnotatedWith(Blue.class)
                 bind(Transmission.class).to(ManualTransmission.class).ifParentAnnotatedWith(Red.class)
                 but with private modules you can get this functionality

链接又断了。

看起来馅饼服务器已关闭。 它可能会回来，但更新链接以指向此错误似乎更好； 感谢@rcchan提供内容。

嗨，这个代码示例在最新版本的 Guice 中仍然有效吗？ 似乎PrivateModule改变了包并且configurePrivateBindings变成configure ？
