Question

这是我的Controller类：

@Controller
@SessionAttributes({"list", "selectedCompany"})
public class ProspectController {

protected static Logger logger = Logger.getLogger("controller");

@Resource(name = "ProspectWebServiceTemplate")
private WebServiceTemplate prospectWebServiceTemplate;
@Resource(name = CountryWebServiceTemplate")
private WebServiceTemplate countryWebServiceTemplate;
@Resource(name = "CompanyWebServiceTemplate")
private WebServiceTemplate companyWebServiceTemplate;

/**
 * Handles and retrieves the subscribe page
 */
@RequestMapping(value = "/addProspect", method = RequestMethod.GET)
public String getAddProspectPage(@ModelAttribute("prospectAttribute") ProspectDto prospectDto,Model model) {
    logger.debug("Received request to show add prospect page");

    final GetAllCountriesRequest request = new GetAllCountriesRequest();
    GetAllCountriesResponse response = (GetAllCountriesResponse) countryWebServiceTemplate
            .marshalSendAndReceive(request);


    List<CountryDto> list = new ArrayList<CountryDto>();
    List<CountryDto> allCountries =  response.getCountriesDto();
    if (response != null && allCountries != null) {
        for (CountryDto dto : allCountries) {
            list.add(dto);
        }
    }

    model.addAttribute("list", list);

    final GetAllCompaniesRequest requestComp = new GetAllCompaniesRequest();
    GetAllCompaniesResponse responseComp = (GetAllCompaniesResponse) companyWebServiceTemplate
            .marshalSendAndReceive(requestComp);

    List<CompanyDto> listComp = new ArrayList<CompanyDto>();
    List<CompanyDto> allCompanies =  responseComp.getCompaniesDto();
    if (responseComp != null &&  allCompanies != null) {
        for (CompanyDto dto : allCompanies) {
            listComp.add(dto);
        }
    }
    model.addAttribute("listComp", listComp);



    model.addAttribute("prospectAttribute", new SaveProspectRequest());
    return "addProspect";
}


@RequestMapping(value = "/saveProspect", method = RequestMethod.POST)
public String doSave(
        @ModelAttribute("prospectAttribute")  SaveProspectRequest request,
        Model model) {
    logger.debug("Received request to subscribe");
    try {
        SaveProspectResponse response = (SaveProspectResponse) prospectWebServiceTemplate
                .marshalSendAndReceive(request);
        logger.debug(response.getId());

        model.addAttribute("response", "Success! ");
        model.addAttribute("prospect", response.getFirstName());

    } catch (SoapFaultClientException sfce) {
        logger.error("We sent an invalid message", sfce);
        model.addAttribute("error",
                "Validation error! We cannot process your subscription");

    } catch (Exception e) {
        logger.error("Unexpected exception", e);
        model.addAttribute("error",
                "Server error! A unexpected error has occured");
    }

    model.addAttribute("prospectAttribute", request);

    return "addProspect";
}

}

这是我的jsp文件

我有一个公司列表，它在控制器类中，当我将它发送到jsp文件时，它可以工作。但是，在浏览器中，当我从组合框中选择一个公司时，它应该向控制器类的“doSave”方法发送包含公司的Prospect类型的modelAttribute，但它不起作用！可能是什么问题？

将modelAttribute从jsp绑定到控制器
