JSON 含有中文传到前台变？？？的解决方法（使用springmvc）

错误举例  
controller得到的json是\{“total”:8,”limit”:3,”order”:”asc”,”offset”:0,”rows”:\[\{“content”:”adadad”,”id”:3,”user\_name”:”aaa”,”title”:”adad”,”creattime”:”2015-03-31 11:25:40”\},\{“content”:”adadad”,”id”:4,”user\_name”:”aaa”,”title”:”adad”,”creattime”:”2015-03-31 11:27:11”\},\{“content”:”311313”,”id”:1,”user\_name”:”系统管理员”,”title”:”233”,”creattime”:”2015-03-31 10:21:51”\}\]\}

到了页面，火狐firebug看到的json就是

\{“total”:8,”limit”:3,”order”:”asc”,”offset”:0,  
“rows”:\[\{“content”:”adadad”,”id”:3,”user\_name”:”aaa”,  
“title”:”adad”,”creattime”:”2015-03-31 11:25:40”\},\{“content”:”adadad”,”id”:4,  
“user\_name”:”aaa”,”title”:”adad”,”creattime”:”2015-03-31 11:27:11”\},  
\{“content”:”311313”,”id”:1,”user\_name”:”?????”,”title”:”233”,  
“creattime”:”2015-03-31 10:21:51”\}\]\}  
系统管理员变成了问号

controller如下：

@RequestMapping(value = “/FeedPager.cqzk”)  
@ResponseBody  
public String url\_sa1(HttpServletRequest request, BootPage page,HttpServletResponse response)  
throws ServletException, IOException, RuntimeException \{

BootPage pager = feedBackDao.getBySQLPage("select Feedback.id,Feedback.title,Feedback.content," +
                "Feedback.creattime,Rms_User.user_name from t_Feedback Feedback,Rms_User where Feedback.userId = Rms_User.user_id ", page, null);     
        return (JSONArray.fromObject(pager)).getString(0).toString();
    }

用的spring mvc

解决方法：  
一种：  
spring 3.2 MVC 406 Not Acceptable  
的时候这个问题顺便解决了  
更新了jar包解决的 jackson-1.9.4.jar json-lib-2.4-jdk15.jar ezmorph-1.0.6.jar

二种：

[html] view plain copy
    @RequestMapping(value="/book/getBook.do", produces = "text/html;charset=UTF-8")  
        public @ResponseBody String getBook(String name){  
             List<Book> list =bookService.getBook(); 
             for(Book bo:list){  
                 System.out.println("id:"+bo.getId()+" name:"+bo.getName()+" author:"+bo.getAuthor()); 
             }  
             String json = JSONObject.toJSONString(list); 
             System.out.println("json:"+json); 
            return json; 
        }

在 注解处 加入

[html] view plain copy
    produces = "text/html;charset=UTF-8" 即可
