JSON marsh && unmarsh

Ext 端用

 

//Encodes an Object, Array or other value 
Ext.util.JSON.encode
(Mixed o) : String 

//Decodes (parses) a JSON string to an object. If the JSON is invalid, this 
//function throws a SyntaxError.
Ext.util.JSON.decode
(String json) : Object

 

 

 

Java 端用

//json-lib
//params 例如"{xx:'yy'}";

JSONObject jsonParams = JSONObject.fromObject(params);

String xx= jsonParams.getString("xx");

 

 

//json-lib
JSONSerializer.toJSON(javabean || list of javabean).toString();

//return string
{xx:yy}   or  [{xx:yy},{xx2:yy2}]
