利用fastjson序列化对象为JSON
参考博客：http://blog.csdn.net/zeuskingzb/article/details/17468079
Step1：定义实体类
//用户类public class User { ???private Long id; ???private String name;//增加get/set方法}//定义组，1组有多个用户public class Group { ???private Long id; ???private String name; ???private List<User> users = new ArrayList<User>();//增加get/set方法}Step2：定义测试类，将实体对象转换成JSON格式输出
//测试类public class Test { ???public static void main(String[] args) { ???????Group group = new Group(); ???????group.setId(0L); ???????group.setName("admin"); ???????User guestUser = new User(); ???????guestUser.setId(2L); ???????guestUser.setName("guest"); ???????User rootUser = new User(); ???????rootUser.setId(3L); ???????rootUser.setName("root"); ???????group.getUsers().add(guestUser); ???????group.getUsers().add(rootUser); ???????String jsonString = JSON.toJSONString(group); ???????System.out.println(jsonString);
???????Group group2 = JSON.parseObject(jsonString, Group.class);//将json反序列化为对象
} }
输出结果：
{"id":0,"name":"admin","users":[{"id":2,"name":"guest"},{"id":3,"name":"root"}]}
