杜松子酒辅助注射与工厂"Unable to create or inherit binding"的问题

Question

我得到一个奇怪的错误，我不能通过使用辅助注射:

[DEBUG] [project] - Rebinding com.gwtplatform.mvp.client.DesktopGinjector
[DEBUG] [project] - Invoking generator com.google.gwt.inject.rebind.GinjectorGenerator
    [ERROR] [project] - Factory com.jorsek.editor.gin.EditorClientFactory could not be created
    [ERROR] [project] - Error injecting com.jorsek.editor.gin.EditorClientFactory: Unable to create or inherit binding: No @Inject or default constructor found for com.jorsek.editor.gin.EditorClientFactory

所需节点的路径:

com.projectname.client.application.resourceworkspace。ResourceWorkspacePresenter [com.gwtplatform.mvp.client.gin.AbstractPresenterModule.bindPresenter (AbstractPresenterModule.java: 122)]-> com.jorsek.editor.gin.EditorClientFactory[@注入com.projectname.client.application.resourceworkspace.ResourceWorkspacePresenter的构造函数]

我是这样设置的:

我的工厂:

public interface EditorClientFactory {
/**
 * Create a new DOMModel via assisted injection initializing the model 
 * with the document entity and it's DOM document content.
 * 
 * @param document
 * @param domDocument
 * @return
 */
public DOMModel create(Entity document, Document domDocument);
}

我模块:

public class EditorClientModule extends AbstractGinModule {
@Override
protected void configure() {
    install(new GinFactoryModuleBuilder().build(EditorClientFactory.class));
    bind(DOMModel.class).to(SyncedDOMModel.class);
}
}

com.jorsek.editor.impl.SyncedDOMModel:

public class SyncedDOMModel implements DOMModel {

@Inject
private SyncedDOMModel(){} /* For GIN/GUICE */
@AssistedInject
public SyncedDOMModel(CollabClient client, CollabClientFactory collabFactory, @Assisted Entity ref, @Assisted Document domDoc){
    }
}

这是我如何试图注入我的工厂使用:

@AssistedInject
public ResourceWorkspacePresenter(final EventBus eventBus, final MyView view, final MyProxy proxy, APIService apiService, EditorClientFactory editorFactory, @Assisted EntityLocator entityLocator) {
    super(eventBus, view, proxy, ApplicationPresenter.TYPE_SetMainContent);

    this.editorFactory = editorFactory;
    this.apiService = apiService;
     System.out.println("E Locator: " + entityLocator);
}

这就是我如何使用我的工厂(从来没有得到这么远):

editorFactory.create(doc, domDoc);

有人知道为什么会发生这种情况吗?

如果有帮助的话，我正在使用GWTP RC2。

谢谢,凯西

你的代码是不正确的(我不知道它是否会解决你的问题，但这是一个开始):你不应该bind(DOMModel.class)，而是告诉工厂:

install(new GinFactoryModuleBuilder()
    .implement(DOMModel.class, SyncedDOMModel.class)
    .build(EditorClientFactory.class));
