Controller通过@RequestBody接收参数

@RequestMapping(value="/update.json")
@ResponseBody
public Object update(@RequestBody User user) {

user.setStatus(1);
user.setLast_login_time(new Date());
boolean result = userService.updateUser(user);
JsonAndView jsonAndView = null;
if (result) {
jsonAndView = JsonAndView.successJsonAndView();
} else {
jsonAndView = JsonAndView.failedJsonAndView();
}
jsonAndView.setReturnValue(user);
return jsonAndView;
}
