本文整理了Java中javax.faces.event.ActionListener类的一些代码示例，展示了ActionListener类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。ActionListener类的具体详情如下：
包路径：javax.faces.event.ActionListener
类名称：ActionListener

ActionListener介绍

[英]A listener interface for receiving ActionEvents. An implementation of this interface must be thread-safe. A class that is interested in receiving such events implements this interface, and then registers itself with the source UIComponent of interest, by calling addActionListener().
[中]用于接收ActionEvents的侦听器接口。此接口的实现必须是线程安全的。对接收此类事件感兴趣的类实现此接口，然后通过调用addActionListener()向感兴趣的源UIComponent注册自己。

代码示例

代码示例来源：origin: primefaces/primefaces

@Override
public void processAction(ActionEvent event) throws AbortProcessingException {
  UIComponent source = event.getComponent();
  // don't use event#getFacesContext() - it's only available in JSF 2.3
  Map<Object, Object> attrs = FacesContext.getCurrentInstance().getAttributes();
  if (source instanceof Widget) {
    attrs.put(Constants.DIALOG_FRAMEWORK.SOURCE_WIDGET, ((Widget) source).resolveWidgetVar());
  }
  attrs.put(Constants.DIALOG_FRAMEWORK.SOURCE_COMPONENT, source.getClientId());
  base.processAction(event);
}
