JQuery异步获取返回值中文乱码的解决方法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
public void searchUserList(int page, int rows, HttpServletRequest request, HttpServletResponse response) throws IOException{
System.out.println("idcard="+idCard+" page="+page+" rows="+rows);
List<User> list = userService.findByIDCard(idCard);
int totalRecord = list.size();
int totalPage = totalRecord%rows == 0 ? totalRecord/rows : (totalRecord/rows+1);
int index = (page-1)*rows;
int pageSize = rows;
String json = "{\"total\": \""+totalPage+"\", \"page\": \""+page+"\", \"records\": \""+totalRecord+"\", \"rows\": [";
for (int i = index; i < pageSize + index && i<totalRecord; i++) {
User u = 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");
PrintWriter out = 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();
}
