17         user.setName("wangwu");
18         user.setAge(12);
19         
20         try {
21             BeanUtils.copyProperties(otherUser, user);
22         } catch (IllegalAccessException e) {
23             // TODO Auto-generated catch block
24             e.printStackTrace();
25         } catch (InvocationTargetException e) {
26             // TODO Auto-generated catch block
27             e.printStackTrace();
28         }
29         
30         System.out.println(otherUser.getId() + "," + otherUser.getName() + "," + otherUser.getAge());
31     }
32 }

好处：避免了繁琐的get和set方法。
