关于json数据传输乱码问题

关于json数据传输乱码问题     
   ArrayList<weather> lists=new ArrayList<weather>();
 
JSONArray jsonArray=JSONArray.fromObject(lists);

        String result=jsonArray.toString();

        writer.write("("+result+")");

在数据传输的，或者将result打印出来以后出现乱码的现象，结果是：

[{"data":"16\u65e5\uff08\u5468\u4e00\uff09","tem":"19\u2103/15\u2103","wea":"\u9634\u8f6c\u591a\u4e91","win":"\u4e1c\u5317\u98ce\u00203\u002d4\u7ea7"},{"data":"16\u65e5\uff08\u5468\u4e00\uff09","tem":"19\u2103/15\u2103","wea":"\u9634\u8f6c\u591a\u4e91","win":"\u4e1c\u5317\u98ce\u00203\u002d4\u7ea7"},{"data":"16\u65e5\uff08\u5468\u4e00\uff09","tem":"19\u2103/15\u2103","wea":"\u9634\u8f6c\u591a\u4e91","win":"\u4e1c\u5317\u98ce\u00203\u002d4\u7ea7"},{"data":"16\u65e5\uff08\u5468\u4e00\uff09","tem":"19\u2103/15\u2103","wea":"\u9634\u8f6c\u591a\u4e91","win":"\u4e1c\u5317\u98ce\u00203\u002d4\u7ea7"},{"data":"16\u65e5\uff08\u5468\u4e00\uff09","tem":"19\u2103/15\u2103","wea":"\u9634\u8f6c\u591a\u4e91","win":"\u4e1c\u5317\u98ce\u00203\u002d4\u7ea7"},{"data":"16\u65e5\uff08\u5468\u4e00\uff09","tem":"19\u2103/15\u2103","wea":"\u9634\u8f6c\u591a\u4e91","win":"\u4e1c\u5317\u98ce\u00203\u002d4\u7ea7"},{"data":"16\u65e5\uff08\u5468\u4e00\uff09","tem":"19\u2103/15\u2103","wea":"\u9634\u8f6c\u591a\u4e91","win":"\u4e1c\u5317\u98ce\u00203\u002d4\u7ea7"}]

可能是json数据格式问题，

我是这样接解决的：在前端设置一个回调函数，

String jsonp=request.getParameter("callbackparam");

JSONArray jsonArray=JSONArray.fromObject(lists);

 String result=jsonArray.toString();

writer.write(jsonp+"("+result+")");

然后通过回调函数将json对象带回去，结果为：

0:{data:
"16日（周一）", tem: "19℃/15℃", wea: "阴转多云", win: "东北风 3-4级"}

1:{data:
"16日（周一）", tem: "19℃/15℃", wea: "阴转多云", win: "东北风 3-4级"}

2:{data:
"16日（周一）", tem: "19℃/15℃", wea: "阴转多云", win: "东北风 3-4级"}

3:{data:
"16日（周一）", tem: "19℃/15℃", wea: "阴转多云", win: "东北风 3-4级"}

4:{data:
"16日（周一）", tem: "19℃/15℃", wea: "阴转多云", win: "东北风 3-4级"}

5:{data:
"16日（周一）", tem: "19℃/15℃", wea: "阴转多云", win: "东北风 3-4级"}

6:{data:
"16日（周一）", tem: "19℃/15℃", wea: "阴转多云", win: "东北风 3-4级"}
