如何在Java中检测方法调用？

import java.lang.reflect.Method;

public class MethodCallDetection {
    public static void main(String[] args) throws Exception {
        // 获取目标类的Class对象
        Class<?> targetClass = TargetClass.class;

        // 获取目标方法的Method对象
        Method targetMethod = targetClass.getMethod("targetMethod", String.class);

        // 设置方法的访问权限
        targetMethod.setAccessible(true);

        // 创建目标对象
        TargetClass targetObject = new TargetClass();

        // 调用目标方法
        targetMethod.invoke(targetObject, "Hello, World!");
    }
}

class TargetClass {
    public void targetMethod(String message) {
        System.out.println("Target method called with message: " + message);
    }
}
