这就是网络。我的GWT应用程序中的xml:

我的问题是,当我这样做的时候,我如何使它对GWT-RPC也是可用的
服务模块:
@Override
protected void configureServlets() {
bind(MyService.class).to(MyServiceImpl.class).in(Scopes.SINGLETON);
serve("/app/myservice").with(MyServiceImpl.class);
}
对于定义为以下内容的 RPC:
@RemoteServiceRelativePath("myservice")
public interface MyService extends RemoteService
当应用程序加载时,会抛出以下错误:
[错误]javax . servlet . servlet异常:servlet必须绑定为singletons。key[type = com . myapp . server . service impl . myserviceimpl,annotation=[none]]未在单独范围内绑定。[错误]在com . Google . inject . servlet . servlet definition . init(servlet definition . Java:104)[错误]在com . Google . inject . servlet . managedservletpipeline . init(managedservletpipeline . Java:82)[错误]在com . Google . inject . servlet . guice filter . init(guice filter . Java:172)[错误
将实现(*Impl)类绑定到@Singleton范围,在ServletModule
中:
bind(MyServiceImpl.class).in(Singleton.class);
serve("/app/myservice").with(MyServiceImpl.class);
或者通过注释类本身,正如xybrek所建议的那样。
简单的回答是用< code>@Singleton注释RPC服务实现
如,com.google.inject.Singleton
为了回答你的“也当我这样做的时候”,你可能只是使用了错误的辛格尔顿声明
@Override
public void configureServlets() {
bind(ImageServlet.class).in(Singleton.class);
serve("/images").with(ImageServlet.class);
