多部分、spring boot和JBoss-不存在必需的请求部分“文件”

Question

我有一个应用程序，它使用spring boot和嵌入式Tomcat进行开发，并在生产服务器上部署在JBoss 6.4 EAP上。在添加对JBoss的支持后，多部分文件上传停止工作。在这两个容器上，它都抛出了MissingServletRequestPartException。

将MultipartConfigElement添加到ServletSynstrationBean修复了tomcat上的此问题，但对于JBoss仍然不起作用。您有什么想法吗？

配置：

@Bean
public ServletRegistrationBean dispatcherRegistration(DispatcherServlet dispatcherServlet, MultipartConfigElement
        multipartConfig) {
    ServletRegistrationBean registration = new ServletRegistrationBean(dispatcherServlet);
    registration.getUrlMappings().clear();
    registration.addUrlMappings("/*");
    registration.setMultipartConfig(multipartConfig);
    return registration;
}

终点：

@RequestMapping(method = POST)
@ResponseBody
public SomeResponse uploadFileWithComment(
    @RequestParam(value = "file") final MultipartFile file,
    @RequestParam(value = "comment") String comment) {
    ...
}

这里讨论https://github.com/spring-projects/spring-boot/issues/2958建议如果您正在使用@EnableAutoConfigance，那么您需要执行以下操作，因为springbooautoconfig会导致问题：

@EnableAutoConfiguration(exclude = {MultipartAutoConfiguration.class})

定义以下bean

@Bean(name = "multipartResolver") 
public CommonsMultipartResolver commonsMultipartResolver(){ 
CommonsMultipartResolver resolver = new CommonsMultipartResolver(); resolver.setMaxUploadSize(50*1024*1024); return resolver ; 
}


@Bean @Order(0) public MultipartFilter multipartFilter()
{ 
MultipartFilter multipartFilter = new MultipartFilter(); 
multipartFilter.setMultipartResolverBeanName("multipartResolver"); 
return multipartFilter; 
}
