java - 通过 GinModuleAdapter 在 GIN 应用程序上使用 Grapher

Question

我一直在尝试使用Grapher在我的 GIN 项目上。但尝试创建一个 Injector 来提供 InjectorGrapher 却没有成功。

就在我的代码的第一行:

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

它崩溃了

什么给出了？

Answer 1

弄清楚: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，所以我将其转换成这样，这也有效。

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