Question

我正在尝试上传 .jpg 文件，但收到此消息:

但是我有一个多部分解析器:

<bean id="multipartResolver"    class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
        <property name="maxUploadSize" value="1000000" />
    </bean>

现在我的问题是如何解决这个问题，这里有更多代码:

上传 Controller :

@Controller
@RequestMapping(value = "/upload")
public class UploadController {
private static final Logger LOGGER = LoggerFactory.getLogger(UploadController.class);

private String folderToUpload = "/resources/img";

@RequestMapping(value = "/form", method = RequestMethod.GET)
public ModelAndView formUpload(){
    ModelAndView mv = new ModelAndView("upload/form");

    return mv;
}

@RequestMapping(value = "/form", method = RequestMethod.POST)
public ModelAndView procesFormUpload(HttpSession session, @RequestParam("photofile") MultipartFile file) {
    ModelAndView mv = new ModelAndView("upload/list");

    String uploadLocation = Upload(session).getAbsolutePath();
    LOGGER.debug("Name File: [{}]", file.getOriginalFilename());
    LOGGER.debug("Size File: [{}]", file.getSize());
    LOGGER.debug("Type File: [{}]", file.getContentType());

    File photo = new File(uploadLocation + File.separator + file.getOriginalFilename());
    try {
        file.transferTo(photo);
        LOGGER.debug("File [{}]", photo.getAbsolutePath());
    } catch (Exception ex) {
        LOGGER.error("Kan file niet uploaden");
        LOGGER.error("stacktrace: {}", ex.getMessage());
    }
    return mv;
}
private File Upload(HttpSession session) {
    String locationFullPath = session.getServletContext().getRealPath(folderToUpload);
    LOGGER.debug("location full path: [{}]", locationFullPath);
    File test = new File(locationFullPath);

    if(!test.exists()){
        LOGGER.debug("wtf");
        test.mkdirs();
    }
    return test;
}
}

                </tr>
            </tbody>
        </table>

    </form>

希望有人能帮助我!

    @Configuration
public class FileConfig {

    @Bean(name = "multipartResolver")
    public CommonsMultipartResolver multipartResolver() {
        CommonsMultipartResolver multipartResolver = new CommonsMultipartResolver();
        multipartResolver.setMaxUploadSize(10485760);
        return multipartResolver;
    }
}
