Java Spring MVC-多部分表单数据

我得到了这个jsp文件：

<form:form class="main-section" modelAttribute="demandeForm" commandName="demandeForm" 
name="demandeForm" method="post" enctype="multipart/form-data;charset=UTF-8" action="/validate.do?valider=valider">

<!-- Some input text -->

<ul>
   <li>
      <input type="file" name="file" >
   </li>
   <li>
      <input type="file" name="file" >
   </li>
   <li>
      <input type="file" name="file" >
   </li>
</ul>

和我的控制器：

@RequestMapping(method = RequestMethod.POST, params = "valider")
public String valider(@Valid final DemandeForm pForm, final BindingResult pResult, final Model pModel, final HttpServletRequest pRequest) {

    // do things

    if (pResult.hasErrors()) {
        return MY_VUE;
    }

    // do things

}

pResult

有绑定错误，下面是错误：

Failed to convert property value of type java.lang.String[] 
to required type org.springframework.web.multipart.MultipartFile[] 
for property file; nested exception is java.lang.IllegalStateException: 
Cannot convert value of type [java.lang.String] to required type 
[org.springframework.web.multipart.MultipartFile] for property file[0]: 
no matching editors or conversion strategy found 

自从我在enctype值上添加了

charse=UTF-8

之后，就出现了错误。我需要这个，因为我有这个口音和UTF-8字符的文件

如何处理此问题？

您可以将控制器参数设置为

@RequestParam("file") MultipartFile file

然后您可以获得文件名、大小等。。。像

file.getOriginalFilename()

您是否尝试过：

<bean id="multipartResolver"
class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
  <property name="defaultEncoding"><value>utf-8</value></property>
</bean>

以你的形式

<bean id="multipartResolver"
class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
  <property name="defaultEncoding"><value>utf-8</value></property>
</bean>

enctype="multipart/form-data;charset=UTF-8"
