fastjson 使用实例

Entity

publicclassUser {

privateLong id;

privateString name;

publicLong getId() { returnid; }

publicvoidsetId(Long id) { this.id = id; }

publicString getName() { returnname; }

publicvoidsetName(String name) { this.name = name; }

}

publicclassGroup {

privateLong id;

privateString name;

privateList<User> users = newArrayList<User>();

publicLong getId() { returnid; }

publicvoidsetId(Long id) { this.id = id; }

publicString getName() { returnname; }

publicvoidsetName(String name) { this.name = name; }

publicList<User> getUsers() { returnusers; }

publicvoidsetUsers(List<User> users) { this.users = users; }

}

Encode

importcom.alibaba.fastjson.JSON;

Group group = newGroup();

group.setId(0L);

group.setName("admin");

User guestUser = newUser();

guestUser.setId(2L);

guestUser.setName("guest");

User rootUser = newUser();

rootUser.setId(3L);

rootUser.setName("root");

group.getUsers().add(guestUser);

group.getUsers().add(rootUser);

String jsonString = JSON.toJSONString(group);

System.out.println(jsonString);

output

{

"name":"admin",

"id":0,"users":[

{"name":"guest","id":2},

{"name":"root","id":3}

]

}

Decode

Group group2 = JSON.parseObject(jsonString, Group.class);
