从Facelets 1.1迁移到Faclets 2.0-FaceletViewHandler [英] Migrating from facelets 1.1 to faclets 2.0 - FaceletViewHandler

问题描述

我已阅读以下帖子，该帖子非常有帮助 从JSF 1.2迁移到JSF 2.0

I have read the following post which was very helpful Migrating from JSF 1.2 to JSF 2.0

但是我遇到了迁移问题，因为我有一个从FaceletViewHandler扩展的自定义视图处理程序-这不是faclets 2的一部分.

but I am having a problem with the migration as I have a custom view handler which extends from FaceletViewHandler - this is not part of faclets 2.

我正在以下迁移JBoss 4.2.2: -从JSF 1.2到JSF 2.0

I am migrating on JBoss 4.2.2 the following: - JSF 1.2 to JSF 2.0

我也想迁移小孔-我遇到了上述问题.

I also want to migrate the faclets - which i have a problem described above.

在我的应用程序中，我也正在使用Tomahawk-此迁移是否有任何问题?

In my application, I am also using Tomahawk - is there any problem with this migration?

谢谢.

Elico.

推荐答案

正确的是，您需要将FaceletViewHandler替换为

Right, you need to replace FaceletViewHandler by ViewHandlerWrapper.

因此，以下是基本的FaceletViewHandler实现:

So the following basic FaceletViewHandler implementation:

import javax.faces.application.ViewHandler;
import com.sun.facelets.FaceletViewHandler;

public class MyViewHandler extends FaceletViewHandler {

    public MyViewHandler(ViewHandler parent) {
        super(parent);
    }

    // ...
}

需要进行如下更新:

import javax.faces.application.ViewHandler;
import javax.faces.application.ViewHandlerWrapper;

public class MyViewHandler extends ViewHandlerWrapper {

    private ViewHandler wrapped;

    public MyViewHandler(ViewHandler wrapped) {
        this.wrapped = wrapped;
    }

    @Override
    public ViewHandler getWrapped() {
        return wrapped;
    }

    // ...
}

我已经相应更新了有关迁移问题的答案.

I've updated my answer on the migration question accordingly.
