我如何设计适当的Java Swing MVC设计-这个MVC设计示例正确吗？

Question

I designed controller class in mvc like below.

public class ControllerMr implements Observer {

ModelMr modelmr = new ModelMr();
PanelMr vpanelmr= new PanelMr();

public ControllerMr() {
    this.modelmr.registerObserver(this);
    this.vpanelmr.registerObserver(this);
}

when i instantiate controller class, i create model and view class. my view here is swing panel. for example i add this panel to tab or frame in another view.

i connect my controller to model and view with the help of observer pattern. You see in the constructor, i register my controller to the model and view. so there is indirect connection with observer pattern, and concurrency management will be more easy.

is this design true , if it is wrong, should i set my view and model outer of controller class like below

ControllerMr controllermr= new ControllerMr();
controllermr.setview(vpanelmr);
controllermr.setmodel(modelmr);

and also there will be some modifications in controller class for the above design. for example i must change constructor of controller class

Thank you very much for your effort.

当您想将Controller，Model和View彼此分开，以便将来可以（或多或少）互换时，可以使用MVC，现在的操作方式意味着没有View或Model的情况下控制器，我建议您将它们彼此分开创建并传递引用，而同时仍保持MVC模式
