Jsonobject about the conversion relationship between Xml,json,bean

1.JSON conversion to Java

@Test          Public void Jsontojava () {            System.out.println ("JSON string to Java code");             = "{\" password\ ": \" \ ", \" username\ ": \" Zhang San \ "}";//Add escape            character = Jsonobject.fromobject (jsonstr)            ; = Jsonobj.getstring ("username");             = jsonobj.optstring ("password");            System.out.println ("JSON--->java\n username=" + username                    + "\ t password=" + password); c19/>}

Operation Result:

JSON string to Java code JSON--->java username= Zhang San     password=

2.convert Java to JSON

@Test          Public void Javatojson () {            System.out.println ("Java code encapsulated as JSON string");             New Jsonobject ();            Jsonobj.put ("username", "Zhang San");            Jsonobj.put ("password", "" ");            System.out.println ("Java--->json \ n" + jsonobj.tostring ());        }

Operation Result:

Java code encapsulated as JSON string Java--->json {"username": "Zhang San", "Password": ""}

3.JSON conversion to XML

@Test Public voidJsontoxml () {System.out.println ("JSON string to XML string"); String Jsonstr= "{\" password\ ": \" \ ", \" username\ ": \" Zhang San \ "}"; Jsonobject JSON=Jsonobject.fromobject (JSONSTR); XMLSerializer XMLSerializer=NewXMLSerializer (); Xmlserializer.setrootname ("User_info"); Xmlserializer.settypehintsenabled (false); String XML=Xmlserializer.write (JSON); System.out.println ("JSON--->xml \ n" +XML); }

Operation Result:

JSON string to XML string JSON---><?xml version= "1.0" encoding= "UTF-8"?><user_info>< Password/><username> Zhang San </username></user_info>

4.XML conversion to JSON

@Test          Public void Xmltojson () {            System.out.println ("XML string to JSON string");             = "<?xml version=\" 1.0\ "encoding=\" utf-8\ "? ><user_info><password></password><username > Zhang San </username></user_info> ";             New XMLSerializer ();             = Xmlserializer.read (XML);            System.out.println ("XML--->json \ n" + json.tostring ());        }

Operation Result:

9:20:18default  type Stringxml--->json {"password": [], "username": "Zhang San "}

5.javaBean conversion to JSON

@Test          Public void Javabeantojson () {            System.out.println ("JavaBean to JSON string");             New UserInfo ();            Userinfo.setusername ("Zhang San");            Userinfo.setpassword ("");             = Jsonobject.fromobject (userInfo);            System.out.println ("JavaBean--->json \ n" + json.tostring ());        }

Operation Result:

JavaBean to JSON string JavaBean--->json {"password": "", "username": "Zhang San"}

6.javaBean to XML

  @Test  public  void   Javabeantoxml () {System.out.println (" JavaBean to XML string "
   
     = 
    new  
     UserInfo ();            Userinfo.setusername ( "Zhang San" 
     ""  = Jsonobject.fromobject (userInfo); XMLSerializer XMLSerializer  = new              XMLSerializer ();            String XML  = Xmlserializer.write (JSON, "UTF-8"  javabean--->xml \ n "+ XML); }
   

Operation Result:

JavaBean to XML string JavaBean---><?xml version= "1.0" encoding= "UTF-8"?><o>< Password type= "string"/><username type= "string" > Zhang San </username></o>

 PackageOrg.xiaowu.json.demo; Public classUserInfo { PublicString username;  PublicString password;  PublicString GetUserName () {returnusername; }     Public voidSetusername (String username) { This. Username =username; }     PublicString GetPassword () {returnpassword; }     Public voidSetPassword (String password) { This. Password =password; }}
