加入 produces = "text/plain;charset=utf-8" 例子： @RequestMapping(value = "/user/updatepwd", method = { RequestMethod.POST }, produces = "text/plain;charset=utf-8") @ResponseBody public ResponseMode

通过@ResponseBody标签返回JSON数据的方法都报406错： 解决方法： @RequestMapping(value = "/user/updatepwd", method = { RequestMethod.POST }, produces = "text/plain;charset=utf-8") 将produces 的值改为application/json;charset
