*/
Convert data to JSON
public static string Createjsonstring (string key, Object value) {

return jsonobject.tostring ();

}

}

Person.java:

Copy Code code as follows:

Package com.lihua.json.domain;

private int id;
private String name;
Private String address;

Public person () {
}

public person (int ID, string name, string address) {
Super ();
This.id = ID;

public int getId () {
return ID;
}

public void setId (int id) {
This.id = ID;
}

Public String GetName () {

Jsonservice.java:

Copy Code code as follows:

Package com.lihua.json.service;

Import java.util.ArrayList;
Import Java.util.HashMap;
Import java.util.List;
Import Java.util.Map;

Import Com.lihua.json.domain.Person;

public class Jsonservice {

Public Jsonservice () {

}

Declare a method of a person type and add a single object to it
Public Person Getperson () {
person person = new Person (1001, "Jack", "Beijing");
return person;

}
Declare a method of a list<person> type and add multiple objects to it
Public list<person> Getlistperson () {
list<person> list = new arraylist<person> ();
Person Person1 = new Person ("Jack", "Guangdong");
Person Person2 = new Person ("Rose", "Guangxi");
List.add (Person1);
List.add (Person2);
return list;
}
Declares a method of a list<string> type and adds a single object to it
Public list<string> getliststring () {
list<string> list = new arraylist<string> ();
List.add ("Beijing");
List.add ("Shanghai");
List.add ("Guangdong");
List.add ("Guangxi");
return list;
}

Declare a method of a list<map<string,object>> type and add multiple objects to it
Public list<map<string,object>> Getlistmap () {

list<map<string,object>> list = new arraylist<map<string,object>> ();
map<string,object> map1 = new hashmap<string,object> ();
Map1.put ("id", 100);
Map1.put ("name", "Jack");
Map1.put ("Address", "Beijing");

map<string,object> map2 = new hashmap<string,object> ();
Map2.put ("id", 100);
Map2.put ("name", "Rose");
Map2.put ("Address", "Shanghai");

List.add (MAP1);
List.add (MAP2);
return list;
}


}

Test.java:

Copy Code code as follows:

Package com.lihua.json.test;

Import java.util.List;
Import Java.util.Map;

Import Com.lihua.json.domain.Person;
Import Com.lihua.json.service.JsonService;
Import Com.lihua.json.tools.JsonTools;

public class Test {

Public Test () {

}

public static void Main (string[] args) {
String msg = "";
New A Jsonservice object
Jsonservice service = new Jsonservice ();
Declares a person object and obtains data from the person object
Person person = Service.getperson ();
Converts the data in the person object to JSON data and saves it to MSG
msg = jsontools.createjsonstring ("person", person);
SYSTEM.OUT.PRINTLN ("---->" +msg);

list<person> list = Service.getlistperson ();
msg = jsontools.createjsonstring ("person", list);
SYSTEM.OUT.PRINTLN ("---->" +msg);


list<map<string, object>> listmap = Service.getlistmap ();
msg = jsontools.createjsonstring ("person", listmap);
SYSTEM.OUT.PRINTLN ("---->" +msg);
}
}
