wicket - 如何在 wicket 6.x 或 7.x 中使用受保护的 IFeedbackMessageFilter[] getFilters()

Question

我正在尝试将以下代码从 wicket-1.4.9 转换为 wicket-6.x/7.x，但没有得到解决方案。请帮忙，因为我是 Apache Wicket 的新手

@Override
protected IFeedbackMessageFilter[] getFilters() {
    final List<IFeedbackMessageFilter> filters = new ArrayList<IFeedbackMessageFilter>();
    getPage().visitChildren(FeedbackPanel.class, new IVisitor<FeedbackPanel>() {

        @Override
        public Object component(FeedbackPanel component) {
            if (pageFeedback.equals(component)) {
                return CONTINUE_TRAVERSAL_BUT_DONT_GO_DEEPER;
            }
            filters.add(component.getFilter());
            return CONTINUE_TRAVERSAL;
        }
    });

    return filters.toArray(new IFeedbackMessageFilter[filters.size()]);
} 

Answer 1

它应该是这样的：

@Override
protected IFeedbackMessageFilter[] getFilters() {
    final List<IFeedbackMessageFilter> filters = new ArrayList<IFeedbackMessageFilter>();

    getPage().visitChildren(FeedbackPanel.class, new IVisitor<FeedbackPanel, Void>() {

        @Override
        public void component(FeedbackPanel component, IVisit<Void> visit) {
            if (pageFeedback.equals(component)) {
                visit.dontGoDeeper();
                return;
            }
            filters.add(component.getFilter());
        }
    });

    return filters.toArray(new IFeedbackMessageFilter[filters.size()]);

}
