class="tags" href="/tags/FanShe.html" title=反射>反射的概念

class="tags" href="/tags/FanShe.html" title=反射>反射是一种机制，利用该机制可以在程序运行过程中对类进行解剖并操作类中的所有成员(成员变量，成员方 法，构造方法)

使用class="tags" href="/tags/FanShe.html" title=反射>反射操作类成员的前提

要获得该类字节码文件对象，就是Class对象

class="tags" href="/tags/FanShe.html" title=反射>反射在实际开发中的应用

开发IDE(集成开发环境)，比如IDEA,Eclipse
各种框架的设计和学习 比如Spring，Hibernate，Mybaits…

Class对象的获取方式

三种获取方法

方式1: 通过类名.class获得
方式2：通过对象名.getClass()方法获得
方式3：通过Class类的静态方法获得： static Class forName(“类全名”) * 每一个类的Class对象都只有一个。

class="tags" href="/tags/FanShe.html" title=反射>反射操作构造方法

class="tags" href="/tags/FanShe.html" title=反射>反射之操作构造方法的目的

• 获得Constructor对象来创建类的对象。 Constructor类概述
• 类中的每一个构造方法都是一个Constructor类的对象（无参构造，有参构造）

Class类中与Constructor相关的方法

1. Constructor getConstructor(Class… parameterTypes)
   * 根据参数类型获得对应的Constructor对象。
   * 只能获得public修饰的构造方法
2. Constructor getDeclaredConstructor(Class… parameterTypes)
   * 根据参数类型获得对应的Constructor对象
   * 可以是public、protected、(默认)、private修饰符的构造方法。
3. Constructor[] getConstructors()
   * 获得类中的所有构造方法对象，只能获得public的
4. Constructor[] getDeclaredConstructors()
   * 获得类中的所有构造方法对象 可以是public、protected、(默认)、 private修饰符的构造方法。

Constructor对象常用方法

1. T newInstance(Object… initargs)"—— 根据指定的参数创建对象
2. void setAccessible(true) 设置"暴力class="tags" href="/tags/FanShe.html" title=反射>反射"——是否取消权限检查，true取消权限检查，false表示不取消

class="tags" href="/tags/FanShe.html" title=反射>反射之操作成员方法

Method类概述

class="tags" href="/tags/FanShe.html" title=反射>反射之操作成员方法的目的

• 操作Method对象来调用成员方法

Method类概述

• 每一个成员方法都是一个Method类的对象

Class类中与Method相关的方法

• Method getMethod(String name,Class…args);
  • 根据方法名和参数类型获得对应的构造方法对象，只能获得public的
• Method getDeclaredMethod(String name,Class…args);
  • 根据方法名和参数类型获得对应的构造方法对象，包括public、protected、(默认)、private的
• Method[] getMethods();
  • 获得类中的所有成员方法对象，返回数组，只能获得public修饰的且包含父类的
• Method[] getDeclaredMethods();
  • 获得类中的所有成员方法对象，返回数组,只获得本类的，包括public、protected、(默认)、 private的

Method对象常用方法

• Object invoke(Object obj, Object… args)
  • 调用指定对象obj的该方法
  • args：调用方法时传递的参数
• void setAccessible(true)
  • 设置"暴力访问"——是否取消权限检查，true取消权限检查，false表示不取消

class="tags" href="/tags/FanShe.html" title=反射>反射之操作成员变量

Field类概述

class="tags" href="/tags/FanShe.html" title=反射>反射之操作成员变量的目的

• 通过Field对象给对应的成员变量赋值和取值

Field类概述

• 每一个成员变量都是一个Field类的对象。

Class类中与Field相关的方法

• Field getField(String name);
  • 根据成员变量名获得对应Field对象，只能获得public修饰
• Field getDeclaredField(String name);
  • 根据成员变量名获得对应Field对象，包括public、protected、(默认)、private的
• Field[] getFields();
  • 获得所有的成员变量对应的Field对象，只能获得public的
• Field[] getDeclaredFields();
  • 获得所有的成员变量对应的Field对象，包括public、protected、(默认)、private的

Field对象常用方法

void set(Object obj, Object value)
void setInt(Object obj, int i)
void setLong(Object obj, long l)
void setBoolean(Object obj, boolean z)
void setDouble(Object obj, double d)
Object get(Object obj)
int getInt(Object obj) long getLong(Object obj) boolean
getBoolean(Object ob) double getDouble(Object obj) void
setAccessible(true);暴力class="tags" href="/tags/FanShe.html" title=反射>反射，设置为可以直接访问私有类型的属性。 Class getType();
获取属性的类型，返回Class对象。

注意：

• setXxx方法都是给对象obj的属性设置使用，针对不同的类型选取不同的方法。
• getXxx方法是获取对象obj对应的属性值的，针对不同的类型选取不同的方法。
