SSM框架取不到jsp页面值

点击查询 把结果显示在下拉选单中

Controller
/*
* 药房盘点页
* 根据时间查询盘点单号
*/
@RequestMapping("querydh")

public String querydh(HttpServletRequest request,String starttime , String endtime) {

System.out.println("controlle1");
String starttime1 =request.getParameter(starttime);
String endtime1 =request.getParameter(endtime);//获取不到值
System.out.println("controlle1"+starttime1+endtime1);
request.setAttribute("list", yfServer.querydh(starttime1, endtime1));
return "yaofang/yaofangpandian";
}

server
public interface YaoFangServer {
//药房根据时间查询盘点单号
public Map<String,Object >querydh( String starttime,String endtime);

impl
@Service
@Transactional
public class YaoFangServerimpl implements YaoFangServer{
@Resource(name="yaoFangMapper")
private YaoFangMapper yfMapper;

//时间查询 单号

@Override
public Map<String, Object> querydh(String starttime, String endtime) {

return yfMapper.querydh(starttime, endtime);
}

public interface YaoFangMapper {
/*
* 根据时间 查询盘点单号
*/
public Map<String,Object> querydh( String starttime,String endtime);

<select id="querydh">
SELECT dbo.mz_yfpdd.pddh
FROM
dbo.mz_yfpdd
WHERE dbo.mz_yfpdd.pdsj>#{starttime} and dbo.mz_yfpdd.pdsj #{endtime};
</select>

你form表单提交地址是不是忘记写了，那个action值，如果是点击查询提交的话，那个按钮改成submit提交按钮，你可以试试看，加上提交url，查询按钮type改成submit。

我是用AJAX提交的
