1.The request sent by the client was syntactically incorrect ()

问题原因,无法接收参数。
可能原因,参数名称不正确,获取接收参数为空,如果可能为空,可设置如下
@RequestParam(value = "file", required = false) MultipartFile file
2.如果参数设置正常,后台controller接收到的文件为null
可能没有添加配置

配置文件中添加:
<!-- id="multipartResolver"必须是multipartResolver -->
<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<!-- maxUploadSize:文件上传的最大值以byte为单位 -->
<property name="maxUploadSize" value="1024000"></property>
</bean>
