问题描述

如何将多部分配置添加到使用带有 RequestMapping 注释的方法的控制器的 spring mvc 应用程序中?

How do I add in multipart configuration to a spring mvc app which uses controllers with methods annotated with RequestMapping?

背景:

我想启用 csrf 保护，因此在我的 spring 配置中添加了 security:csrf 标签.我有一个控制器类，其中包含一个用 RequestMapping 注释的方法，用于上传文件.我也跟着 警告说明 围绕多部分，我在安全过滤器上方添加了多部分过滤器.当我在添加 csrf 标签后尝试上传文件时，我在缺少 getParts() 方法时遇到异常.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 并再次尝试上传.结果:

I want to enable csrf protection and so have added the security:csrf tag in my spring config. I have a controller class with a method annotated with RequestMapping used for uploading files. I also followed the caveat instructions around multipart whereby I added the multipart filter above the security filter. When I tried to upload a file after adding the csrf tag I got an exception around a missing getParts() method. A quick google highlighted this was due to using a version of jetty which was based on the servlet 2.5 spec. I upgraded jetty-maven-plugin to 8.1.14.v20131031 and tried uploading again. Resulting in:

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)

我应该把 xml 设置的多部分配置放在哪里?所有文档都说要在 web.xml 中特定 servlet 的 servlet 标记中添加 multipart-config.不过，我的应用程序只有一个 servlet.所以我添加了它，但我仍然遇到同样的问题.

Where do I put the multipart configuration for xml setup? All documentation says to add the multipart-config in the servlet tag for the specific servlet in web.xml. There is only a single servlet for my application though. So I added it to that and still I get the same issue.

<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，该规范来自 http://www.mkyong.com/web-development/the-web-xml-deployment-descriptor-examples/.

I also updated the schema location at the top of web.xml to point at version 3.0 of the servlet spec, sourced from http://www.mkyong.com/web-development/the-web-xml-deployment-descriptor-examples/.

有什么帮助吗?

推荐答案

我相信您遇到了与 SPR-11373.具体来说，servlet 规范并不清楚在过滤器中执行多部分解析时应该发生什么.

I believe you are having issues related to SPR-11373. Specifically, the servlet specification is not clear on what should happen when performing multipart resolution within a Filter.

您是否尝试过使用 commons-fileupload 代替?这可能是您最好的选择.首先添加如下依赖:

Have you tried using commons-fileupload instead? This is likely your best option. First add the following dependency:

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

接下来确保您的根应用程序上下文中有以下 bean 定义.

Next ensure you have the following bean definition in your root application context.

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

您可以找到一个完整的工作示例，其中包含 commons-upload(首选此解决方案)和使用 allowCasualMultipartParsing SEC-2471

You can find a complete working example with both commons-upload (prefer this solution) and using tomcat using allowCasualMultipartParsing on SEC-2471
