我想编写一个简单的java代理,它可以打印由java程序调用的方法的名称.

例如,我想要的java程序是:

public class TestInstr {

public static void sayHello() {
    System.out.println("Hello !");
}

public static void main(String args[]) {
    sayHello();
    sayHello();
    sayHello();
 }

}

我想展示这样的东西:

method sayHello has been called
Hello !
method sayHello has been called
Hello !
method sayHello has been called
Hello !

谢谢你的帮助!

是否有任何工具可用于记录运行java应用程序的所有方法调用？

例如.

String str = "...";
String anotherString = str.trim();

应该记录这样的事情:

..method call trim() from class java.lang.String
