错误400 - 错误请求在Spring 3.2.8中提交表单

Question

我有这个控制器：

import java.util.Collections;
import java.util.List;
import java.util.Locale;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;



@Controller
public class SearchServicesController extends SearchController {

    protected void checkSessionAttributes (HttpServletRequest request, HttpServletResponse response, Locale locale ) {

        super.checkSessionAttributes(request, response, locale);

    }

    /**
     *
     * @param request the http servlet request.
     * @param model the spring model.
     *
     */
    @SuppressWarnings("unchecked")
    @RequestMapping(value = "/services.do", method = RequestMethod.GET)
    public String initForm(HttpServletRequest request, HttpServletResponse response, Model model, Locale locale) {

        model.addAttribute("deviceStoreForm"  , new DeviceStoreForm());

        return "servicesSearchView";
    }

    /**
     *
     * @param request the http servlet request.
     * @param model the spring model.
     *
     */
    @RequestMapping(value = "/services.do", method = RequestMethod.POST)
    public String formSubmission(HttpServletRequest request, HttpServletResponse response, 
            Model model, Locale locale, DeviceStoreForm deviceStoreForm) {

        checkSessionAttributes(request, response, locale);

        return "servicesSearchView";
    }
}

以及此表格：

<form:form action="/ecat/services.do" method="post" commandName="deviceStoreForm" class="TTWForm1" id="simpleSearchForm">

                <div id="sidebar_search">

                    <input  name="searchString" size="34" maxlength="255"
                                                onBlur="if(this.value=='')this.value='<fmt:message key="search.by.keyword" />';" 
                                                onKeyPress="doClickQuickSearch('submit',event)"
                                                onFocus="if(this.value=='<fmt:message key="search.by.keyword" />')this.value='';"   

                                                <c:choose>

                </fieldset>             
            </form:form>

当我在formSubmission函数中添加参数DeviceStoreForm deviceStoreForm时出现问题;然后，当我提交表单时，我在jsp中得到错误400 - 错误请求，我在错误日志或控制台中看不到任何异常
