我试图将表单中的数据简单地发布到我的spring控制器,我总是收到错误消息:

服务器响应状态为400必需字符串参数 “profileId”不存在

我的uiBinder中的表格:

<g:FormPanel ui:field="formPanel">
        <g:HTMLPanel>

            <table border="0" width="100%">
                <tr>
                    <td width="20%"><g:HTML HTML="Profile ID:" /></td>
                    <td width="80%"><g:TextBox name="profileId" ui:field="profileId" width="300px" "/>

                    <td width="20%"><g:HTML HTML="Logo: " /></td>
                    <td width="80%"> <g:FileUpload name="logo" ui:field="logoUpload"/> </td>        
                </tr>           
            </table><br/>

        </g:HTMLPanel>
</g:FormPanel>
我的spring控制器:

@RequestMapping(method = RequestMethod.POST, value = "/create")
@ResponseStatus(HttpStatus.CREATED)
@ResponseBody
public void create(@RequestParam("profileId") String profileId,
                   @RequestParam("logo") MultipartFile logo) throws BadRequestException, InternalException, NotFoundException{
    log.info("Request to create new user.");
}
使用chrome开发工具跟踪的请求有效负载:

---WebKitFormBoundaryX7km8vQwaC3LtjqO内容配置:表单数据;name=profileId

测试1 ---WebKitFormBoundaryX7km8vQwaC3LtjqO内容配置:表单数据;名称=徽标;filename=test1.png内容类型:image/png

---WebKitFormBoundaryX7km8vQwaC3LtjqO-

Eclipse控制台输出:

谢谢你的帮助

我需要将MulitpartResolver添加到servlet或applicationcontext中

<bean id="multipartResolver"
    class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
    <property name="maxUploadSize" value="250000"/>
</bean> 
已在问题中讨论过

可能的副本
<bean id="multipartResolver"
    class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
    <property name="maxUploadSize" value="250000"/>
</bean>
