BeanUtils--内省加强

 1 //1、设置属性  setXxx
 2         SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM-dd");
 3         String data="2010-5-6";
 4         User u=new User();
 5         BeanUtils.setProperty(u, "id", "jack");
 6         BeanUtils.setProperty(u, "age", "90");
 7         BeanUtils.setProperty(u, "birthday", sdf.parse(data));
 8         System.err.println(u);
 9         System.err.println("===========================");
10         //2、获取属性
11         String id= BeanUtils.getProperty(u, "id");
12         System.err.println(id);
13         //3、整体赋值
14         Map<String,Object> map=new HashMap<String, Object>();
15         map.put("id", "Rose");
16         map.put("age", "99");
17         BeanUtils.populate(u, map);
18         System.err.println(u);
