Trouble Compiling with Gin

 原文  2012-02-11 02:04:04  2   2    java/ gwt/ dependency-injection/ guice/ gin

Question

I'm using Gin 1.5 and GWT 2.4 The project built just fine before I added Gin, but now it doesn't: 

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

The error is: 

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

What am I doing wrong? I have guice-assistedinject-snapshot.jar and guice-snapshot.jar on my classpath, in that order.

The line that causes the error is in my entry point class is: 

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

FooGinjector.java: 

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

  EventBus eventBus();

  PlaceHistoryHandler historyHandler();

}

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。

When I first saw this I thought of the obvious module inherits was missing in the gwt.xml 

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

Since you answered your own question, I thought I'd add in something else I found when converted over to GIN.

I converted the HelloMVP app over to GIN, based on a partial tutorial I found on the web. What I've found is adding in Activities & Places is where it gets more complicated if you aren't familiar with the guice syntax.

If you go on and try to run your code with places, you will need to know the proper bind syntax in the configure method for your GINModule: 

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...

This one threw me for a while as I wasn't sure how to declare the singleton here. I don't know if you got past this issue or not.
