Я пытаюсь записать файл в папку удаленной системы с помощью составного запроса, при загрузке размером более 1 МБ возникает ошибка:

«stacktrace»:[«org.springframework.web.multipart.MultipartException: не удалось проанализировать составной запрос сервлета; вложенным исключением является java.io.IOException: org.apache.tomcat.util.http.fileupload.Исключение FileUploadBase$IOFileUploadException: не удалось выполнить обработку запроса multipart / form-data. /upload_c8f18d91_ba00_4810_96de_422cdd2e9b75_00000016.tmp (отказано в разрешении)

Я попытался установить некоторые свойства в файле app.properties

 spring.http.multipart.max-file-size=10MB
spring.http.multipart.max-request-size=10MB
spring.http.multipart.file-size-threshold=10MB
spring.servlet.multipart.max-file-size = 10MB
spring.servlet.multipart.max-request-size = 10MB
spring.servlet.multipart.file-size-threshold=10MB
  

Метод контроллера :

 @RestController
@RequestMapping(path = PcoCloudServicesController.PATH, produces = MediaType.APPLICATION_JSON_VALUE)
@MultipartConfig(
    location = "/tmp",
    fileSizeThreshold = 10485760,
    maxFileSize = 10485760,
    maxRequestSize = 10485760)
public class PcoCloudServicesController {
  private static final String TENANT_ID = "tenantId";
  @PostMapping("/writefile")
  public JsonNode writeFileToFolderInPco(
      HttpServletRequest request,
      @RequestParam("file") MultipartFile file,
      @RequestParam("file-data") String fileData) {
    logger.debug(
        "Controller method for writing file payload: {} and name: {}",
        file,
        file.getOriginalFilename());
    IPCoCloudServices pcoService =
        PCoCloudServicePersistance.getInstance(
            (String) request.getAttribute(StringConstants.TENANT_ID));
    return pcoService.writeFileToFolderInPco(file, fileData);
  }
}
}
  

Здесь я попытался с аннотацией @MultipartConfig, но по-прежнему не удается проанализировать запрос /upload_c8f18d91_ba00_4810_96de_422cdd2e9b75_00000016.tmp (отказано в разрешении)

После некоторых усилий, наконец, я нашел, что вызвало реальную проблему. В Spring Dispatcher Servlet нет многочастного преобразователя по умолчанию. Поэтому нам нужно ввести компонент с именем «MultipartResolver», например :

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

Здесь, используя метод setMaxUploadSize, я определил максимальный размер файла, который я хочу поддерживать.
это решает мою проблему с максимальным размером файла.
Но здесь нам нужно перехватить исключение MaxUploadSizeExceededException в общем классе обработчика исключений.
