spring boot 前台向后台用thymeleaf传参

Question

前台代码

 <form th:action="@{/loadredisstatus}"  method="post" th:object="${redisbaseinfo}" >
     <select  class="width-40 chosen-select"   name="knowledgePointIdSet" data-placeholder="选择redis">
        <option th:each="redisinfolist:${session.redisinfolist}" th:value="${redisinfolist.getRedisIp()}+':'+${redisinfolist.getRedisPort()}"
                th:text="${redisinfolist.getRedisIp()}+':'+${redisinfolist.getRedisPort()}"
               th:field="*{ipandport}"   >模块名称</option>
     </select>
        <input type="submit" />
    </form>

后台代码

   @RequestMapping(value = "/loadredisstatus", method = RequestMethod.POST)
    public void loginPost(Model model,
                            @ModelAttribute(value = "redisbaseinfo")  RedisBaseInfo redisbaseinfo,
                            HttpServletResponse response,
                            HttpSession session) {
        String ipandport=redisbaseinfo.getIpandport();
        System.out.println("in loadredisstatus "+ipandport);
        if(ipandport!=null&&!ipandport.trim().equals("")){
            String [] arr=ipandport.split(":");
            addCourse(response,session,arr[0],arr[1]);
        }
    }

RedisBaseInfo代码

 public class RedisBaseInfo extends BaseObject {

    private  String ipandport;

    public String getIpandport() {
        return ipandport;
    }

    public void setIpandport(String ipandport) {
        this.ipandport = ipandport;
    }
}

如上所示现在

 th:object="${redisbaseinfo}" 

和

 th:field="*{ipandport}" 

两处报错，运行的话根本运行不起来，想实现的功能是选择一个下拉菜单选项并点击按钮提交后吧他的text封装到redisbaseinfo类里面传到后台处理，请问具体该怎么改这段代码呢

其实我想说能不能把格式调整下.....
