如何记录JSF ajax请求的方法表达式

我已经了解了如何在过滤器中记录何时请求是ajax请求以及它来自哪个页面

我真正想做的是记录ajax请求的实际用途。例如ajax调用的方法的名称（例如此调用中的“findAddress:

我真正想做的是记录ajax请求的实际用途，例如ajax调用的方法的名称（例如“findAddress”）在这个调用中：
特别是关于侦听器方法名称，请看这里：@tt\u dev interest。我可能会使用它，但是facesContext在我的筛选器中不可用，因为它不是bean。我确实相信我可以从标准请求/会话中的某个地方获取facesContext，但我不记得是什么时候e、 我的应用程序在调试中搜索，但没有结果。没有理由否决这个问题。我知道100分奖金会引起你的注意。再次感谢@BalusC，由于你的回答，我对JSF了解更多。解决方案听起来可行，而且可能是。我会在我着手实施你的时候奖励奖金r建议。不客气。至于赏金，你也可以让系统自动奖励。赏金问题在列表中停留的时间越长，就会有越多的人看到并投票支持问答，特别是在赏金的最后一天。这样，你就可以赚回一点你花在赏金上的钱。
