JSON and Java data conversion (bean, map, and XML are converted to JSON and JSON can be converted back to bean and dynabean)

Examples on the official website

JSON-lib is a Java class package used to convert beans, maps, and XML into JSON and convert JSON back to bean and dynabean.

: Http://json-lib.sourceforge.net/
The third-party package is also required:
Org. Apache. commons (version 3.2 or later)
Org. Apache. oro
Net. SF. ezmorph (ezmorph-1.0.4.jar)
Nu. XOM

1. List

Java code

1. Boolean[] Boolarray =New Boolean[] {True,False,True};
   
2. Jsonarray jsonarray1 = jsonarray. fromobject (boolarray );
3. System. Out. println (jsonarray1 );
4. // Prints [true, false, true]
6. List list =NewArraylist ();
7. List. Add ("first ");
8. List. Add ("second ");
9. Jsonarray jsonarray2 = jsonarray. fromobject (list );
10. System. Out. println (jsonarray2 );
11. // Prints ["first", "second"]
13. Jsonarray jsonarray3 = jsonarray. fromobject ("['json', 'is', 'easy']");
14. System. Out. println (jsonarray3 );
15. // Prints ["JSON", "is", "easy"]

2. Map
Java code

1. Map map =NewHashmap ();
2. Map. Put ("name", "JSON ");
3. Map. Put ("bool", Boolean. True );
5. Map. Put ("int ",NewINTEGER (1 ));
   
6. Map. Put ("arr ",NewString [] {"A", "B "}
   );
7. Map. Put ("func", "function (I) {return this. Arr [I];}");
8. Jsonobject JSON = jsonobject. fromobject (MAP );
9. System. Out. println (JSON );
10. // {"Func": function (I) {return this. arr [I] ;}, "arr": ["A", "B"], "int": 1, "name": "JSON", "bool ": true}

3. Bean
Java code

1. /**
2. * Bean. Java
3. Private string name = "JSON ";
4. Private int pojoid = 1;
5. Private char [] Options = new char [] {'A', 'F '};
6. Private string func1 = "function (I) {return this. Options [I];}";
7. Private jsonfunction func2 = new jsonfunction (New String [] {"I"}, "return this. Options [I];");
8. */
9. Jsonobject = jsonobject. fromobject (NewJsonbean ());
10. System. Out. println (jsonobject );
11. // {"Func1": function (I) {return this. options [I];}, "pojoid": 1, "name": "JSON", "options": ["A", "F"], "func2 ": function (I) {return this. options [I] ;}}

4. Beans
Java code

1. /**
2. * Private int row;
3. Private int Col;
4. Private string value;
5. *
6. */
7. List list =NewArraylist ();
8. Jsonbean2 jb1 =NewJsonbean2 ();
9. Jb1.setcol (1 );
10. Jb1.setrow (1 );
11. Jb1.setvalue ("XX ");
13. Jsonbean2 jb2 =NewJsonbean2 ();
14. Jb2.setcol (2 );
15. Jb2.setrow (2 );
16. Jb2.setvalue ("");
19. List. Add (jb1 );
20. List. Add (jb2 );
22. Jsonarray ja = jsonarray. fromobject (list );
23. System. Out. println (JA. tostring ());
24. // [{"Value": "XX", "row": 1, "col": 1 },{ "value": "", "row": 2, "col": 2}]

5. string to Bean
Java code

1. String JSON = "{name = \" JSON \ ", bool: True, INT: 1, double: 2.2, FUNC: function (a) {return a ;}, array: [1, 2]} ";
2. Jsonobject = jsonobject. fromstring (JSON );
3. Object bean = jsonobject. tobean (jsonobject );
4. Assertequals (jsonobject. Get ("name"), propertyutils. getproperty (bean, "name "));
5. Assertequals (jsonobject. Get ("bool"), propertyutils. getproperty (bean, "bool "));
6. Assertequals (jsonobject. Get ("int"), propertyutils. getproperty (bean, "int "));
7. Assertequals (jsonobject. Get ("double"), propertyutils. getproperty (bean, "double "));
8. Assertequals (jsonobject. Get ("func"), propertyutils. getproperty (bean, "func "));
9. List expected = jsonarray. tolist (jsonobject. getjsonarray ("array "));
10. Assertequals (expected, (list) propertyutils. getproperty (bean, "array "));

Java code

1. String JSON = "{\" value \ ": \" XX \ ", \" Row \ ": 1, \" Col \ ": 1 }";
2. Jsonobject = jsonobject. fromstring (JSON );
3. Jsonbean2 bean = (jsonbean2) jsonobject. tobean (jsonobject, jsonbean2.Class);
4. Assertequals (jsonobject. Get ("col "),NewINTEGER (bean. getcol ()));
5. Assertequals (jsonobject. Get ("row "),NewINTEGER (bean. getrow ()));
6. Assertequals (jsonobject. Get ("value"), Bean. getvalue ());

6 JSON to XML
1)
Jsonobject JSON = new jsonobject (true );
String xml = xmlserializer. Write (JSON );

<O class = "object" null = "true">

2)
Jsonobject JSON = jsonobject. fromobject ("{\" Name \ ": \" JSON \ ", \" bool \ ": True, \" int \ ": 1 }");
String xml = xmlserializer. Write (JSON );
<O class = "object">
<Name type = "string"> JSON </Name>
<Bool type = "Boolean"> true </bool>
<Int type = "Number"> 1 </int>
</O>
<O class = "object">
<Name type = "string"> JSON </Name>
<Bool type = "Boolean"> true </bool>
<Int type = "Number"> 1 </int>
</O>
3)
Jsonarray JSON = jsonarray. fromobject ("[1, 2, 3]");
String xml = xmlserializer. Write (JSON );
<A class = "array">
<E type = "Number"> 1 </E>
<E type = "Number"> 2 </E>
<E type = "Number"> 3 </E>
</A>

7. XML to JSON
<A class = "array">
<E type = "function" Params = "I, j">
Return matrix [I] [J];
</E>
</A>
<A class = "array">
<E type = "function" Params = "I, j">
Return matrix [I] [J];
</E>
</A>

Jsonarray JSON = (jsonarray) xmlserializer. Read (XML );
System. Out. println (JSON );
// Prints [function (I, j) {return matrix [I] [J];}]
