用反射访问私有成员变量

用JAVA反射机制访问私有成员变量
1. PrivateTester.java

package com.test;

public class PrivateTester {
	
	private String name="hello world";
	
	public String getName(){
		return this.name;
	}
}

2. ReflectionTest.java

package com.test;

import java.lang.reflect.Field;

public class ReflectionTest {

	/**
	 * @param args
	 * @throws Exception 
	 * @throws  
	 */
	public static void main(String[] args) throws Exception {
		PrivateTester pt=new PrivateTester();
		
		Class<?> classType=PrivateTester.class;
		
		Field field=classType.getDeclaredField("name");
		
		field.setAccessible(true);  //压制JAVA访问控制检查
		
		String str=(String)field.get(pt);
		
		System.out.println(str);
		
		field.set(pt, "world");
		
		System.out.println(field.get(pt));
	}
