Convert objects to JSON format in Java and NET

Convert objects to JSON format in Java

 

1. Import package:

2. Compile the entity class:

Public class StudVo {

Int id;

String name;

Public int getId (){

Return id;

}

Public void setId (int id ){

This. id = id;

}

Public String getName (){

Return name;

}

Public void setName (String name ){

This. name = name;

}

Public int getAge (){

Return age;

}

Public void setAge (int age ){

This. age = age;

}

Int age;

Public StudVo (int id, String name, int age ){

Super ();

This. id = id;

This. name = name;

This. age = age;

}

 

}

 

3. Test class:

Public class T1 {

 

/**

* @ Param args

*/

Public static void main (String [] args ){

List <StudVo> list = new ArrayList <StudVo> ();

List. add (new StudVo (1, "haha1", 22 ));

List. add (new StudVo (2, "haha2", 22 ));

List. add (new StudVo (3, "haha3", 22 ));

 

System. out. println (net. sf. json. JSONSerializer. toJSON (list ));

}

 

}

 

4. Test Results

[{"Id": 1, "age": 22, "name": "haha1" },{ "id": 2, "age": 22, "name ": "haha2" },{ "id": 3, "age": 22, "name": "haha3"}]

 

 

. NET converts an object to JSON (VS2008 +)

1. entity class

Public class StudVo

{

Public int Id {get; set ;}

Public String Name {get; set ;}

Public int Age {get; set ;}

}

2. Reference namespace

Using System. Web. Script. Serialization;

3. Test class

JavaScriptSerializer js = new JavaScriptSerializer ();

Var list = new List <StudVo> {

New StudVo {Id = 1, Name = "Haha1", Age = 22 },

New StudVo {Id = 2, Name = "Haha2", Age = 22 },

New StudVo {Id = 3, Name = "Haha3", Age = 22}

};

Response. Write (js. Serialize (list ));

4. Test Results

[{"Id": 1, "Name": "Haha1", "Age": 22 },{ "Id": 2, "Name": "Haha2 ", "Age": 22 },{ "Id": 3, "Name": "Haha3", "Age": 22}]
