Question

我尝试将简单的POST数据从我的表单发送到我的spring控制器，并且总是收到错误消息：

服务器响应状态为400（必需字符串参数＆＃39;简档＆＃39;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>

视图中的提交：

String actionUrl = com.google.gwt.core.client.GWT.getHostPageBaseURL() + "/create";
formPanel.setAction(actionUrl);
formPanel.setEncoding(FormPanel.ENCODING_MULTIPART);
formPanel.setMethod(FormPanel.METHOD_POST);
formPanel.submit();

我的春季控制员：

@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 dev工具跟踪请求有效负载：

------ WebKitFormBoundaryX7km8vQwaC3LtjqO Content-Disposition：form-data;名称=＆＃34;简档＆＃34;

TEST1   ------ WebKitFormBoundaryX7km8vQwaC3LtjqO Content-Disposition：form-data;命名=＆＃34;标志＆＃34 ;;文件名=＆＃34; test1.png＆＃34;内容类型：image / png

------ WebKitFormBoundaryX7km8vQwaC3LtjqO -

Eclipse控制台输出：

我需要将MulitpartResolver添加到我的servlet（或applicationcontext）

中

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

已在问题MultipartForm handling with Spring

中讨论过
