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']" );
