在Spring MVC上使用Servlet 3.0的MultipartConfig

问题内容：

我如何在Spring MVC应用程序中添加多部分配置，该应用程序使用带有RequestMapping注释的方法的控制器？

背景：

我想启用csrf保护，因此已在spring
config中添加了security：csrf标记。我有一个控制器类，其方法带有用于上传文件的RequestMapping注释。我还遵循有关multipart
的警告说明，从而在安全性过滤器上方添加了multipart过滤器。当我在添加csrf标记后尝试上传文件时，在缺少的getParts（）方法周围出现了异常。一个快速的谷歌强调这是由于使用了基于servlet
2.5规范的码头版本。我将jetty-maven-plugin升级到8.1.14.v20131031，然后尝试再次上传。导致：

org.springframework.web.multipart.MultipartException: Could not parse multipart servlet request; nested exception is java.lang.IllegalStateException: No multipart config for servlet
        at org.springframework.web.multipart.support.StandardMultipartHttpServletRequest.<init>(StandardMultipartHttpServletRequest.java:68)
        at org.springframework.web.multipart.support.StandardServletMultipartResolver.resolveMultipart(StandardServletMultipartResolver.java:58)
        at org.springframework.web.multipart.support.MultipartFilter.doFilterInternal(MultipartFilter.java:110)

如何将多部分配置用于xml设置？所有文档都说要在web.xml中特定servlet的servlet标记中添加multipart-
config。我的应用程序只有一个servlet。所以我添加了它，但仍然遇到相同的问题。

<servlet>
    <servlet-name>SpringDispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet
    </servlet-class>
    <multipart-config>
        <location>/tmp</location>
        <max-file-size>20848820</max-file-size>
        <max-request-size>418018841</max-request-size>
        <file-size-threshold>1048576</file-size-threshold>
    </multipart-config>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/spring/servlet-context.xml
        </param-value>
    </init-param>
    <load-on-startup>10</load-on-startup>
</servlet>

我还更新了web.xml顶部的架构位置，以指向Servlet规范的3.0版，该规范源自http://www.mkyong.com/web-
development/the-web-xml-deployment-descriptor-examples
/。

有什么帮助吗？

问题答案：

我相信您在与SPR-11373相关的问题。具体来说，对于在过滤器中执行多部分解析时应如何处理，Servlet规范尚不清楚。

您是否尝试过使用commons-fileupload？这可能是您的最佳选择。首先添加以下依赖项：

<dependency>
  <groupId>commons-fileupload</groupId>
  <artifactId>commons-fileupload</artifactId>
  <version>1.2.2</version>
</dependency>

接下来，确保您在根应用程序上下文中具有以下bean定义。

<bean id="filterMultipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<property name="maxUploadSize" value="100000000"/>
</bean>

你可以找到一个完整的工作例如既公地上传（喜欢这个解决方案），并使用Tomcat使用allowCasualMultipartParsing在SEC-2471
