用jqgrid異步獲取列表值，遇到個問題，服務器端從數據庫取到的數據沒有出現中文亂碼問題（日志打出來是沒有亂碼的），但是異步傳到客戶的時候卻出現了亂碼。 服務器端已經編碼過了（UTF-8編碼）。開始一直懷疑是客戶端的問題，比如客戶端和服務器端編碼不一致啊，也懷疑是不是jqGrid工具函數中少配了 contentType: "application/x-www-form-urlencoded; charset=utf-8", 等等問題。
結果都不是，糾結了幾個小時，后來經過大牛的提醒發現，原來代碼還是出在服務器端，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+"/n page="+page+"/n 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"); //這里不設置編碼會有亂碼 response.setContentType("text/html;charset=utf-8"); response.setHeader("Cache-Control", "no-cache"); PrintWriter out = response.getWriter(); //輸出中文，這一句一定要放到response.setContentType("text/html;charset=utf-8"), response.setHeader("Cache-Control", "no-cache")后面，否則中文返回到頁面是亂碼 out.print(json.toString()); out.flush(); out.close(); }新聞熱點
