【Java安全】Java反射机制-获取并调用类的成员方法

---

前言

Java反射(Reflection)是Java非常重要的动态特性，通过使用反射我们不仅可以获取到任何类的成员方法(Methods)、成员变量(Fields)、构造方法(Constructors)等信息，还可以动态创建Java类实例、调用任意的类方法、修改任意的类成员变量值等。Java反射机制是Java语言的动态性的重要体现，也是Java的各种框架底层实现的灵魂。

Java reflection (Reflection) is a very important dynamic feature of Java. By using reflection, we can not only obtain the member methods (Methods), member variables (Fields), constructors (Constructors) and other information of any class, but also dynamically create Java classes instance, call any class method, modify the value of any class member variable, etc. The Java reflection mechanism is an important manifestation of the dynamics of the Java language and the soul of the underlying implementation of various Java frame
