Question

我正在使用Gin 1.5和GWT 2.4在添加Gin之前，该项目已经建好了，但现在它没有：

    [ERROR] [foo] - Generator 'com.google.gwt.inject.rebind.GinjectorGenerator' threw an exception while rebinding 'com.foo.html.client.FooGinjector'

错误是：

20:58:04.252 [ERROR] [foo] Generator 'com.google.gwt.inject.rebind.GinjectorGenerator' threw an exception while rebinding 'com.foo.html.client.FooGinjector'

我做错了什么？我的类路径上有guice-assistedinject-snapshot.jar和guice-snapshot.jar，按顺序排列。

导致错误的行在我的入口点类中是：

private final FooGinjector injector = GWT.create(FooGinjector.class);

FooGinjector.java：

@GinModules(FooGinModule.class)
public interface FooGinjector extends Ginjector {

  EventBus eventBus();

  PlaceHistoryHandler historyHandler();

}

Answer 1

我将辅助注入jar移到了类路径中的其他杜松子酒罐上方，现在看起来工作正常。

Answer 2

当我第一次看到这个时，我想到gwt.xml中缺少明显的模块继承

<!-- Other module inherits                                      -->
  <inherits name="com.google.gwt.inject.Inject"/>

既然你回答了自己的问题，我想我会在转换为GIN时添加我发现的其他内容。

我将HelloMVP应用程序转换为GIN，基于我在网络上找到的部分教程。我发现的是添加活动＆amp;如果你不熟悉guice语法，那么它就会变得更加复杂。

如果你继续尝试用地方运行代码，你需要知道GINModule的configure方法中正确的绑定语法：

bind(SimplePanel.class).in(Singleton.class);
bind(EventBus.class).to(SimpleEventBus.class).in(Singleton.class);
//Notice that the interface must be declared first, then the implementation on the binding.
bind(PlaceHistoryMapper.class).to(AppPlaceHistoryMapper.class).in(Singleton.class);
bind(ActivityMapper.class).to(AppActivityMapper.class).in(Singleton.class);
etc...

这个人扔了我一会儿，因为我不知道如何在这里宣布单身人士。我不知道你是否已经过了这个问题。

麻烦编译与杜松子酒
