JQuery异步获取返回值中文乱码的解决方法
用jqgrid异步获取列表值,遇到个问题,服务器端从数据库取到的数据没有出现中文乱码问题(日志打出来是没有乱码的),但是异步传到客户的时候却出现了乱码。服务器端已经编码过了(UTF-8编码)。开始一直怀疑是客户端的问题,比如客户端和服务器端编码不一致啊,也怀疑是不是jqGrid工具函数中少配了contentType:"application/x-www-form-urlencoded;charset=utf-8", 等等问题。
结果都不是,纠结了几个小时,后来经过大牛的提醒发现,原来代码还是出在服务器端,疏忽了。
@RequestMapping(value="/searchUserList.form") @ResponseBody publicvoidsearchUserList(intpage,introws,HttpServletRequestrequest,HttpServletResponseresponse)throwsIOException{ System.out.println("idcard="+idCard+"\npage="+page+"\nrows="+rows); List<User>list=userService.findByIDCard(idCard); inttotalRecord=list.size(); inttotalPage=totalRecord%rows==0?totalRecord/rows:(totalRecord/rows+1); intindex=(page-1)*rows; intpageSize=rows; Stringjson="{\"total\":\""+totalPage+"\",\"page\":\""+page+"\",\"records\":\""+totalRecord+"\",\"rows\":["; for(inti=index;i<pageSize+index&&i<totalRecord;i++){ Useru=list.get(i); json+="{\"id\":\""+u.getUserId()+"\",\"userName\":\""+u.getUserName()+"\",\"idCard\":\""+ u.getIdCard()+"\",\"userTel\":\""+u.getUserTel()+"\",\"userSex\":\""+u.getUserSex()+ "\",\"bankCard\":\""+u.getBankCard()+"\",\"cardStatus\":\""+u.getCardSatus()+"\",\"createTime\":\""+ u.getCreateTime()+"\"}"; if(i!=pageSize+index-1&&i!=totalRecord-1){ json+=","; } } json+="]}"; request.setCharacterEncoding("utf-8");//这里不设置编码会有乱码 response.setContentType("text/html;charset=utf-8"); response.setHeader("Cache-Control","no-cache"); PrintWriterout=response.getWriter();//输出中文,这一句一定要放到response.setContentType("text/html;charset=utf-8"),response.setHeader("Cache-Control","no-cache")后面,否则中文返回到页面是乱码 out.print(json.toString()); out.flush(); out.close(); }
