利用反射获取类的属性名称

类

package com;

public class Test {

 private String name;
 private String pass;
public String getName() {
 return name;
}
public void setName(String name) {
 this.name = name;
}
public String getPass() {
 return pass;
}
public void setPass(String pass) {
 this.pass = pass;
}

}

 

获取类

package com;

import java.lang.reflect.Field;

public class My {

 public static void setAllComponentsName(Object f)

 {
  Field[] fields = f.getClass().getDeclaredFields();
  for (int i = 0, len = fields.length; i < len; i++) {

   try {
    String varName = fields[i].getName();
    boolean accessFlag = fields[i].isAccessible();
    fields[i].setAccessible(true);
    Object o = fields[i].get(f);
    System.out.println("传入的对象中包含一个如下的属性：" + varName + " = " + o);
    fields[i].setAccessible(accessFlag);
   } catch (SecurityException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
   } catch (IllegalArgumentException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
   } catch (IllegalAccessException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
   }
  }
 }

 public static void main(String[] args) {
  setAllComponentsName(new Test());

 }

}
