我有一個類，它創建一個應用程序窗口與一些控件（代碼如下，windowAs.java文件）。在「初始化」類中創建所有元素。這些只是應用程序中許多其他按鈕的幾個按鈕，並且所有按鈕都有「actionPerformed」方法，後面的邏輯非常相似。 在一個單獨的方法中，我將這些按鈕的初始化放在方向代碼中。所有這些「特殊」按鈕都有一些共同點：使用兩個參數（String header []，String query）調用tableCreation方法。如何創建一個匹配這些按鈕定義的切入點？AspectJ切入點從另一個特定的方法

第一個問題我要問的是：爲什麼呢？這不是一個交叉問題，它是常用的功能，所以爲什麼要使用方面？每段代碼的最後一部分都是常見的，所以把它放到一個方法中，並從各個'actionPerformed（）'中調用它。 – dhke
我完全不知道你實際上想要達到什麼目的。你正在描述你的代碼的結構，但不是你想要做的。幫助我理解你的問題，然後我可以幫助你解決你的問題。 – kriegaex
我正在嘗試編寫一個示例應用程序來顯示與無方面完成相同的事情。 我正在尋找所有的方法doSTG（）與一個單一的方面，將自動被包括在單擊按鈕後，將所有調用。 正如安迪克萊門特建議的那樣，我應該使用周圍的建議，但我似乎無法使其工作。 – 0v3rl0rd
