Spring Security&多部分请求

Question

@Controller
@RequestMapping(value = "/api/image")
public class ImageController {

    @PreAuthorize("hasAuthority('ROLE_USER')")
    @RequestMapping(value = "/upload", method = RequestMethod.PUT)
    public @ResponseBody Account putImage(@RequestParam("title") String title, MultipartHttpServletRequest request, Principal principal){
        // Some type of file processing...
        System.out.println("-------------------------------------------");
        System.out.println("Test upload: " + title);
        System.out.println("Test upload: " + request.getFile("file").getOriginalFilename());
        System.out.println("-------------------------------------------");

        return ((Account) ((OAuth2Authentication) principal).getPrincipal());
    }
}

当我尝试上传一个文件和标题时，我得到以下异常。我正在将Content-Type头设置为multipart/form-data。

java.lang.IllegalStateException: Current request is not of type [org.springframework.web.multipart.MultipartHttpServletRequest]: SecurityContextHolderAwareRequestWrapper[ FirewalledRequest[ org.apache.catalina.connector.RequestFacade@1aee75b7]]
    at org.springframework.web.servlet.mvc.method.annotation.ServletRequestMethodArgumentResolver.resolveArgument(ServletRequestMethodArgumentResolver.java:84)
    at org.springframework.web.method.support.HandlerMethodArgumentResolverComposite.resolveArgument(HandlerMethodArgumentResolverComposite.java:75)

    at org.springframework.web.method.support.InvocableHandlerMethod.invokeForRequest(InvocableHandlerMethod.java:117)

我如何在Spring Security后面做文件上传？这个请求似乎从未被转换成MultiPartHttpServerRequest，所以它不起作用？

如果更改方法签名以采用@RequestParam MultipartFile，则会出现如下异常：

DEBUG DefaultListableBeanFactory - Returning cached instance of singleton bean 'imageController'
DEBUG ExceptionHandlerExceptionResolver - Resolving exception from handler [public com.tinsel.server.model.Account com.tinsel.server.controller.ImageController.putImage(java.lang.String,org.springframework.web.multipart.MultipartFile,java.security.Principal)]: java.lang.IllegalArgumentException: Expected MultipartHttpServletRequest: is a MultipartResolver configured?
DEBUG ResponseStatusExceptionResolver - Resolving exception from handler [public com.tinsel.server.model.Account com.tinsel.server.controller.ImageController.putImage(java.lang.String,org.springframework.web.multipart.MultipartFile,java.security.Principal)]: java.lang.IllegalArgumentException: Expected MultipartHttpServletRequest: is a MultipartResolver configured?

DEBUG DispatcherServlet - Could not complete request
java.lang.IllegalArgumentException: Expected MultipartHttpServletRequest: is a MultipartResolver configured?
    at org.springframework.util.Assert.notNull(Assert.java:112)

...但我在XML中配置了一个MultipartResolver：

<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
    <property name="maxUploadSize" value="268435456"/> <!-- 256 megs -->
</bean>

我确实看到了这篇关于在Spring3.0下工作的博客文章--但我正在努力保持更多的最新信息，目前正在使用3.1。是否有更新的修补程序？

问题是我用的是PUT而不是post。Commons FileUpload经过硬编码，仅接受文件的POST请求。

检查那里的isMultipartContent方法。要解决这一问题，可以使用POST或扩展该类并重写该方法，以便按您的喜好工作。

我为此问题打开了FILEUPLOAD-214。
