我一直在尝试在我的 GIN 项目中使用Grapher 。但是试图创建一个 Injector 给 InjectorGrapher 并没有奏效。

就在我的代码的第一行：

    Injector injector = Guice.createInjector( new GinModuleAdapter( new MyGinModule() ) );

它崩溃了

是什么赋予了？

想通了：我的模块有以下行导致 GinModuleAdapter 阻塞（似乎是一个错误）：

 bind(Foo.class).asEagerSingleton();

删除“asEagerSingleton”导致一切正常。但由于这不是我想要的，所以我将其转换为这个，这也有效。

@Provides @Singleton
Foo getFoo() {
    return new Foo();
}
