用fastjson处理json数据 

 1     // json演示序列化和反序列化
 2         User user = new User(0,"测试","0000",1);
 3         String str = JSON.toJSONString(user);
 4         System.out.println(str);
 5         String str1 = "{\"uid\":1,\"uname\":\"发序列化\",\"pwd\":\"123\",\"iAdmin\":1,}";
 6         User userF = JSON.parseObject(str1, User.class);
 7         System.out.println(userF.getUname());
 8         User user1 = new User(0, "测试1", "1234", 0);
 9         User user2 = new User(0, "测试2", "1234", 0);
10         User user3 = new User(0, "测试3", "1234", 0);
11         User user4 = new User(0, "测试4", "1234", 0);
12         User user5 = new User(0, "测试5", "1234", 0);
13         User user6 = new User(0, "测试6", "1234", 0);
14         User user7 = new User(0, "测试7", "1234", 0);
15         User user8 = new User(0, "测试8", "1234", 0);
16         List<User> list = new ArrayList<>();
17         list.add(user1);
18         list.add(user2);
19         list.add(user3);
20         list.add(user4);
21         list.add(user5);
22         list.add(user6);
23         list.add(user7);
24         list.add(user8);
25         String arryF = "[{\"uid\":0,\"isAdmin\":0,\"pwd\":\"1234\",\"uname\":\"测试1\"},{\"uid\":0,\"isAdmin\":0,\"pwd\":\"1234\",\"uname\":\"测试2\"},{\"uid\":0,\"isAdmin\":0,\"pwd\":\"1234\",\"uname\":\"测试3\"},{\"uid\":0,\"isAdmin\":0,\"pwd\":\"1234\",\"uname\":\"测试4\"},{\"uid\":0,\"isAdmin\":0,\"pwd\":\"1234\",\"uname\":\"测试5\"},{\"uid\":0,\"isAdmin\":0,\"pwd\":\"1234\",\"uname\":\"测试6\"},{\"uid\":0,\"isAdmin\":0,\"pwd\":\"1234\",\"uname\":\"测试7\"},{\"uid\":0,\"isAdmin\":0,\"pwd\":\"1234\",\"uname\":\"测试8\"}]\r\n" + 
26                 "";
27         System.out.println(JSON.toJSON(list));
28         List<User> list2 = JSON.parseArray(arryF, User.class);
29         for(User u:list2) {
30             System.out.println(u.getUname());
