我有一个类，它创建一个带有一些控件的应用程序窗口（代码如下，windowAs.java文件）。在“initialize”类中创建所有元素。这些只是应用程序中许多其他按钮的几个按钮，并且所有按钮都具有“actionPerformed”方法，后面有非常相似的逻辑。 在一个单独的方法中，我放置了我想要包含在方面代码中的那些按钮的初始化。所有这些“特殊”按钮都有一些共同点：使用两个参数调用方法tableCreation（String header []，String query）。如何创建与这些按钮的定义相匹配的切入点？

如果您确实想要使用方面执行此操作，那么当您要替换将要发生的事情时，您将使用around建议。 before和after不会影响将要发生的事情。
pointcut click() : execution (* actionPerformed(..));
void around() : click() {
// the code in here will run instead of the actionPerformed method body
// If you make a proceed call, that will run the original body
// proceed();
}
