我尝试使用Ajax,Spring MVC 3.2.0,Tomcat 8.0.9上传多部分文件,但无法使其正常工作。我在stackoverflow(Spring upload file problems,MultipartConfig with Servlet 3.0 on Spring MVC,...)上阅读了很多博客和类似的帖子,这似乎有类似的原因,但无法弄清楚如何解决它。奇怪的是,当文件小于1MB时上传工作,但是当录制的视频超过该大小时,会引发以下错误:
org.springframework.web.multipart.MultipartException: Could not parse multipart servlet request; nested exception is org.apache.commons.fileupload.FileUploadBase$IOFileUploadException: Processing of multipart/form-data request failed. null
org.springframework.web.multipart.commons.CommonsMultipartResolver.parseRequest(CommonsMultipartResolver.java:163)
org.springframework.web.multipart.commons.CommonsMultipartResolver.resolveMultipart(CommonsMultipartResolver.java:139)
org.springframework.web.multipart.support.MultipartFilter.doFilterInternal(MultipartFilter.java:110)
在下文中,您可以看到我所做的所有配置:
AJAX POST-Request:
var videoBlob = e.data;
var pathArray = window.location.pathname.split( '/' );
var userID;
for (i = 0; i < pathArray.length; i++) {
if (pathArray[i].toString() == "edit"){
userID = pathArray[i+1];
}
}
var fd = new FormData();
fd.append('fname', 'video');
fd.append('data', videoBlob);
$.ajax({
url: '/user/edit/uploadVideo/' + userID,
data: fd,
processData: false,
contentType: false,
type: 'POST',
success: function(data)
{
$('#result').html(data + "uploaded by FormData!");
}
});

我定义了MultipartResolver的root-context.xml

</bean>
Java控制器
@RequestMapping(value = "/edit/uploadVideo/{id}", method = RequestMethod.POST)
public @ResponseBody String uploadVideo(@PathVariable long id, MultipartHttpServletRequest request, HttpServletResponse response) throws IOException {
//.... file handling
}
我该如何解决这个问题?
编辑:
我尝试了建议的方法,并使用Servlet实现来管理我的视频文件上传。已进行了以下调整,但仍然会导致类似的错误:
调整后的@Controller:
@RequestMapping(value = "/edit/uploadVideo/{id}", method = RequestMethod.POST)
public String uploadVideo(@PathVariable long id, @RequestParam("data") Part file) {
//...
}
根控制器已被删除,我将multipartResolver添加到servlet-context.xml
<bean id="multipartResolver" class="org.springframework.web.multipart.support.StandardServletMultipartResolver">
</bean>
web.xml中的标记已通过以下Multipart-Configuration进行了扩展:
<servlet>
<servlet-name>appServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath*:servlet-context.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
<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>
</servlet>
但是,我仍然遇到异常,无法上传大于1MB的blob文件:
Could not parse multipart servlet request; nested exception is java.io.IOException: org.apache.tomcat.util.http.fileupload.FileUploadBase$IOFileUploadException: Processing of multipart/form-data request failed. null
org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:927)
org.springframework.web.servlet.FrameworkServlet.doPost(FrameworkServlet.java:822)
javax.servlet.http.HttpServlet.service(HttpServlet.java:644)
org.springframework.web.servlet.FrameworkServlet.service(FrameworkServlet.java:796)
javax.servlet.http.HttpServlet.service(HttpServlet.java:725)
我实现了一个类似的文件上传,其中只选择了一个文件,并且在使用相同配置时完全可以发送大文件。所以我认为它与Ajax POST或附加的blob文件有什么关系?!
答案 0 :(得分:1)
您可以在应用程序中将其添加到活动的Servlet3.0 MultiParsing:
@Bean
public MultipartConfigElement multipartConfigElement() {
MultiPartConfigFactory factory = new MultiPartConfigFactory();
factory.setMaxFileSize("128KB");
factory.setMaxRequestSize("128KB");
return factory.createMultipartConfig();
}
或以XML格式进行。

不是你的确切问题的答案,只是我的2美分。在Spring MVC的帮助下,基本上有两种上传文件的方法:
由于您使用的是Tomcat 8.0.9,Servet 3.0选项为available,我绝对建议您使用它,因为它不会在您的项目中引入另一个外部依赖项。此外,由于它遵循Servlet 3.0规范,这种上传机制的配置现在是java standard,如果您决定从Spring MVC迁移到另一个MVC框架,那么这很好(您的配置值将保持不变同样的。)
如果您无法弄明白IOFileUploadException
,我认为您应该尝试一下。
