Java SpringMVC-upload文件显示客户端发送的请求在语法上不正确

当我使用表单SUBMITION上传包含其他详细信息的文件时，它显示一个错误HTTP Status 400- 类型状态报告 消息 说明客户端发送的请求在语法上不正确

jsp页面

         <form:form method="POST" action="addbanners?${_csrf.parameterName}=${_csrf.token}" modelAttribute="banner" enctype="multipart/form-data">
    <h2>New Banner</h2>
    <table>
    <tr><td>Banner Name</td>
    <td><form:input type="text" name="thematicdayid" id="thematicdayid" path="bannerName" /></td></tr>
    <tr><td>Banner Image</td>
    <td><form:input name="uploadBanner" type="file" id="uploadBanner" path="bannerImage"/></td></tr>
    <tr><td> <button type="submit" class="btn btn-success" id="btnAddBanner">Add</button></td></tr>
    </table>
    </form:form>

我在root-context.xml中添加了以下详细信息

<beans:bean id="multipartResolver"
    class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
    <beans:property name="maxUploadSize" value="100000" />
</beans:bean> 

更改

public ModelAndView addbanners(@ModelAttribute Banner banner,@RequestParam("file") MultipartFile file)

到

我通过改变得到了答案

public ModelAndView addbanners(@ModelAttribute Banner banner,@RequestParam("file") MultipartFile file) to

public ModelAndView addbanners(@ModelAttribute Banner banner,@RequestParam("uploadBanner") MultipartFile file)

改变

<form:input name="uploadBanner" type="file" id="uploadBanner" path="bannerImage"/> to 
<input name="uploadBanner" type="file" id="uploadBanner" path="bannerImage"/> 

到

谢谢@Akash Rajbanshi帮助我找到我的错误

public ModelAndView addbanners(@ModelAttribute Banner banner,@RequestParam("file") MultipartFile file) to

public ModelAndView addbanners(@ModelAttribute Banner banner,@RequestParam("uploadBanner") MultipartFile file)

<form:input name="uploadBanner" type="file" id="uploadBanner" path="bannerImage"/> to 
<input name="uploadBanner" type="file" id="uploadBanner" path="bannerImage"/>
