JSONObject jo = JSONObject.fromObject(map); 常见的java代码转换成json
1:List集合转换成json代码
List list = new ArrayList(); list.add( "first" ); list.add( "second" ); JSONArray jsonArray2 = JSONArray.fromObject( list );
2:Map集合转换成json代码
Map map = new HashMap(); map.put("name", "json"); map.put("bool", Boolean.TRUE); map.put("int", new Integer(1)); map.put("arr", new String[] { "a", "b" }); map.put("func", "function(i){ return this.arr[i]; }"); JSONObject json = JSONObject.fromObject(map);
3:bean转换成json代码
JSONObject jsonObject = JSONObject.fromObject(new JsonBean());
4:数组转换成json代码
boolean[] boolArray = new boolean[] { true, false, true };
JSONArray jsonArray1 = JSONArray.fromObject(boolArray);
5:一般数据转换成json代码
JSONArray jsonArray3 = JSONArray.fromObject("[‘json‘,‘is‘,‘easy‘]" );
