1、List Java代码 boolean[] boolArray =newboolean[]{true,false,true}; JSONArray jsonArray1 = JSONArray.fromObject( boolArray ); System.out.println( jsonArray1 ); // prints [true,false,true] List list =newArrayList(); list.add("first"); list.add("second"); JSONArray jsonArray2 = JSONArray.fromObject( list ); System.out.println( jsonArray2 ); // prints ["first","second"] JSONArray jsonArray3 = JSONArray.fromObject("['json','is','easy']"); System.out.println( jsonArray3 ); // prints ["json","is","easy"]
2、Map Java代码 Map map =newHashMap(); map.put("name","json"); map.put("bool", Boolean.TRUE ); map.put("int",newInteger(1) ); map.put("arr",newString[]{"a","b"} ); map.put("func","function(i){ return this.arr[i]; }"); JSONObject json = JSONObject.fromObject( map ); System.out.println( json ); //{"func":function(i){ return this.arr[i]; },"arr":["a","b"],"int":1,"name":"json","bool":true}
3、BEAN Java代码 /** * Bean.java private String name = "json"; private int pojoId = 1; private char[] ptions = new char[]{'a','f'}; private String func1 = "function(i){ return this.options[i]; }"; private JSONFunction func2 = new JSONFunction(new String[]{"i"},"return this.options[i];"); */ JSONObject jsonObject = JSONObject.fromObject(newJsonBean() ); System.out.println( jsonObject ); //{"func1":function(i){ return this.options[i]; },"pojoId":1,"name":"json","options":["a","f"],"func2":function(i){ return this.options[i]; }}
4、BEANS Java代码 /** * private int row ; private int col ; private String value ; * */ List list =newArrayList(); JsonBean2 jb1 =newJsonBean2(); jb1.setCol(1); jb1.setRow(1); jb1.setValue("xx"); JsonBean2 jb2 =newJsonBean2(); jb2.setCol(2); jb2.setRow(2); jb2.setValue(""); list.add(jb1); list.add(jb2); JSONArray ja = JSONArray.fromObject(list); System.out.println( ja.toString() ); //[{"value":"xx","row":1,"col":1},{"value":"","row":2,"col":2}]
5、String to bean Java代码 String json ="{name=\"json\",bool:true,int:1,double:2.2,func:function(a){ return a; },array:[1,2]}"; JSONObject jsonObject = JSONObject.fromString(json); Object bean = JSONObject.toBean( jsonObject ); assertEquals( jsonObject.get("name"), PropertyUtils.getProperty( bean,"name") ); assertEquals( jsonObject.get("bool"), PropertyUtils.getProperty( bean,"bool") ); assertEquals( jsonObject.get("int"), PropertyUtils.getProperty( bean,"int") ); assertEquals( jsonObject.get("double"), PropertyUtils.getProperty( bean,"double") ); assertEquals( jsonObject.get("func"), PropertyUtils.getProperty( bean,"func") ); List expected = JSONArray.toList( jsonObject.getJSONArray("array") ); assertEquals( expected, (List) PropertyUtils.getProperty( bean,"array") );
Java代码 String json ="{\"value\":\"xx\",\"row\":1,\"col\":1}"; JSONObject jsonObject = JSONObject.fromString(json); JsonBean2 bean = (JsonBean2) JSONObject.toBean( jsonObject, JsonBean2.class); assertEquals( jsonObject.get("col"),newInteger( bean.getCol()) ); assertEquals( jsonObject.get("row"),newInteger( bean.getRow() ) ); 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]; }]
