奇怪的逗号附加@ModelAttribute的问题

Question

平台:Spring 3.1.2,Tomcat 7.0.30

从3.0升级到Spring 3.1后,问题就开始了

我有一个正常的弹簧启用形式:

<c:url value='/healthcare/insurance/policy/save' var="url" />
<form:form commandName="insurancePolicy" action="${url }" method="POST" cssClass="form-horizontal">
  <div class="module">
      <div class="header">
          <strong><spring:message code="insurance.policy.view.formbox" /> </strong>
      </div>
      <div class="module-content row-fluid">
          <div class="span4">

              <div class="control-group">
                  <label class="control-label"><spring:message code="insurance.policy.view.policyId" /></label>
                  <div class="controls">
                      <form:input path="policyId" cssClass="span10" readonly="true" />
                  </div>
              </div>

              <div class="control-group">
                  <label class="control-label"><spring:message code="insurance.policy.view.tpaId" /></label>
                  <div class="controls">
                      <form:select path="tpaId" items="${tpas }" itemLabel="tpaName" itemValue="tpaId" cssClass="span10" />
                  </div>
              </div>

等等.

我提交的方式是:

function save(){
    $("#insurancePolicy").submit();

}

我捕获的方式是通过Controller,它位于一个抽象类中,如下所示:

public abstract class AbstractCrudViewController<T, PK extends Number, META extends T> extends AbstractViewController {

@SuppressWarnings("unchecked")
    @RequestMapping(value="/save", method = RequestMethod.POST)
    protected String save(@ModelAttribute T t, Model model, HttpServletRequest request){

        logger.debug("Executing save for model: {}", t.toString());

        try{

            if (getPrimaryKeyValue(t) == null || ((Number) getPrimaryKeyValue(t)).intValue() <=0 ){
                logger.debug("Creating new record");
                PK pk =  getCrudService().create(t);
                logger.debug("New record created with ID: {}", pk);
                ViewUtil.addSuccess(model, "crud.saveSuccess", request, getPrimaryKeyValue(t));

            }

init绑定器在AbstractViewController中声明为:

public abstract class AbstractViewController {

     @InitBinder
     public void initBinder(WebDataBinder binder) {
        String dateFormat = "dd/MM/yyyy";       
        binder.registerCustomEditor(DateTime.class, new DateTimeEditor(dateFormat,true));
     }

}

好.现在问题是:我正在保存表单,日志说:

DEBUG:com.keype.hawk.hr.mvc.StaffViewController[save]:Executing save for model: Staff [staffId=null, firstName=Steve,, lastName=Harris,, middleName=,, nationality=AF, dob=2012-09-11T00:00:00.000+03:00, status=1000, title=Mr, address1=, address2=, city=, state=, postalCode=, country=AF, homePhoneAreaCode=, homePhone=,, homePhoneExt=, homePhoneAllowSoliciation=, workPhoneAreaCode=, workPhone=null, workPhoneExt=, workPhoneAllowSoliciation=, fax=, mobileAreaCode=, mobile=, mobileAllowSolicitation=, email=null, joiningDate=null, gender=, govtId=, maritalStatus=, passportNumber=, passportExpiryDate=null, totalWorkExperience=, notes=, staffCreated=null, staffModified=null, dateCreated=null, dateModified=null]

注意每个字段后面的逗号.

为了调试,我使用jquery serialize序列化了表单并检查了它,并且没有逗号.然后ajax将这些数据发布到服务器,在@ModelAttribute完成它的工作后,将附加逗号.

任何的想法？什么与Init粘合剂？

我遇到了同样的问题,但Twitter Bootstrap不是原因.

在我的例子中,我们有2个具有相同名称属性的输入.在这种情况下,这两个输入的数据将作为数组发送.由于我的输入是空的,所以数组是myName=,
