如何使用注入器創建 GEF4 FXView/FXEditor

Question

我正在嘗試在使用GEF4 的eclipse rcp 應用程序中創建 GEF4 FXView （或 FXEditor）。 我想構建一個看起來像 GEF4 MVC Logo Example 的視圖，這就是我創建擴展 FXView 的視圖的原因：

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;
    }

}

但它在運行時崩潰：

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

        ...
    }

}

最后，我通過在 FireMvcModule 中添加此綁定解決了我的問題：

火視：

public FireView() {
    super(Guice.createInjector(Modules.override(new FireMvcModule()).with(new FireMvcUiModule())));
}

FireMvc 模塊：

protected void bindIContentPartFactory() {
    binder().bind(new TypeLiteral<IContentPartFactory<Node>>() {
    }).toInstance(new FXLogoContentPartFactory());
}

protected void configure() {
    super.configure();
    bindIContentPartFactory();
}

Answer 1

請確保您的 MANIFEST.MF 沒有通過 Import-Package 和 Required-Bundle 引用 com.google.inject 包。 從所需的包列表中刪除 com.google.inject，因為包導入就足夠了。
