spring mvc 之mvc：annotation-driven

@Controller
@RequestMapping("/Sys/Admin")
public class SysUserController {
@Autowired
private ISysUserSv sysUserSv;


@RequestMapping("/queryUserInfoById")
@ResponseBody
public ObjectqueryUserInfoById(HttpServletRequest request, HttpServletResponse response) {


String userId = request.getParameter("userId");
System.out.println(sysUserSv.querySysUserById(Long.parseLong(userId)).getCreateTime());


return sysUserSv.querySysUserById(Long.parseLong(userId));// "中文乱码";//
}


}

<!-- 转换date数据到String -->

如方法返回Object，则时间将会正常显示为yyyy-MM-dd HH:mm:ss，如果将返回String类型，时间将显示为timestamp类型。
