2.Field.setAccessible()方法

public class AccessibleTest { 
     
        private int id; 
        private String name; 
     
        public AccessibleTest() { 
     
        } 
     
        public int getId() { 
            return id; 
        } 
     
        public void setId(int id) { 
            this.id = id; 
        } 
     
        public String getName() { 
            return name; 
        } 
     
        public void setName(String name) { 
            this.name = name; 
        } 
     
    }

public static void main(String[] args) throws Exception {  
             Class clazz = Class.forName("com.test.accessible.AccessibleTest");  
              AccessibleTest at = new AccessibleTest();  
              at.setId(1);  
              at.setName("AT");  
              for (Field f : clazz.getDeclaredFields()) {  
                  f.setAccessible(true);//AccessibleTest类中的成员变量为private,故必须进行此操作  
                 System.out.println(f.get(at));//获取当前对象中当前Field的value  
             }
