java中遍历属性字段及值

转自：http://www.tqcto.com/article/recommend/162.html

示例代码如下：[java] view plaincopypackage test;

import java.lang.reflect.Field;

interface IEntity{

}

class Entity implements IEntity{
private String s1 = "字符串1";

private String s2 = "字符串2";
}

public class Test {

public static void reflect(IEntity e) throws Exception{
Class cls = e.getClass();
Field[] fields = cls.getDeclaredFields();
for(int i=0; i<fields.length; i++){
Field f = fields[i];
f.setAccessible(true);
System.out.println("属性名:" + f.getName() + " 属性值:" + f.get(e));
}
}

public static void main(String[] args) throws Exception{
IEntity e = new Entity();
reflect(e);
}
}
