我正在尝试在使用GEF4的Eclipse rcp应用程序中创建GEF4 FXView（或FXEditor）。我想构建一个类似于GEF4 MVC Logo Example的视图，这就是为什么我创建扩展FXView的视图的原因：
import java.util.List;
import org.eclipse.gef4.mvc.fx.MvcFxModule;
import org.eclipse.gef4.mvc.fx.ui.MvcFxUiModule;
import org.eclipse.gef4.mvc.fx.ui.parts.FXView;
import com.google.inject.Guice;
import com.google.inject.util.Modules;
public class MyView extends FXView {
public MyView() {
super(Guice.createInjector(Modules.override(new MvcFxModule())
.with(new MvcFxUiModule())));
}
@Override
protected List<? extends Object> getContents() {
// TODO Auto-generated method stub
return null;
}
}
但是它在运行时崩溃：
java.lang.LinkageError: loader constraint violation: loader (instance of org/eclipse/osgi/internal/loader/EquinoxClassLoader) previously initiated loading for a different type with name "com/google/inject/binder/AnnotatedBindingBuilder"
at com.myproject.ui.viewer2d.test.MyMvcFxModule.bindIHandlePartFactory(MyMvcFxModule.java:375)
MyMvcFxModule：
public class MyMvcFxModule extends MvcModule<Node> {
...
protected void bindIHandlePartFactory() {
// TODO: bind to viewer scope, otherwise stateful factories might not
// work properly
binder().bind(new TypeLiteral<IHandlePartFactory<Node>>() {
}).to(FXDefaultHandlePartFactory.class) // <---- error here
.in(AdaptableScopes.typed(FXViewer.class));
}
...
@Override
protected void configure() {
super.configure();
// bind default factories for handles and feedback
bindIHandlePartFactory(); // error
bindIFeedbackPartFactory(); // error
// error on next binding also
...
}
}

编辑：
最后，我通过在FireMvcModule中添加此绑定解决了我的问题：
FireView：
public FireView() {
super(Guice.createInjector(Modules.override(new FireMvcModule()).with(new FireMvcUiModule())));
}
FireMvcModule：
protected void bindIContentPartFactory() {
binder().bind(new TypeLiteral<IContentPartFactory<Node>>() {
}).toInstance(new FXLogoContentPartFactory());
}
protected void configure() {
super.configure();
bindIContentPartFactory();
}
最佳答案
请确保您的MANIFEST.MF不会通过Import-Package和Required-Bundle引用com.google.inject捆绑包。从软件包包列表中删除com.google.inject，因为软件包导入就足够了。
