1. List集合转换成json代码
List list = newArrayList();
list.add( "first" );
list.add( "second" );
JSONArray jsonArray2 =JSONArray.fromObject( list );
2. Map集合转换成json代码
Map map = newHashMap();
map.put("name","json");
map.put("bool",Boolean.TRUE);
map.put("int", newInteger(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 = newboolean[] { 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']" );
