Spring Boot 文件上传 - 对等错误重置连接

Question

我正在使用 Spring Boot 进行文件上传，但出现以下错误。

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. Connection reset by peer

我搜索了这个错误，发现这篇文章说当用户尝试上传大于指定限制的文件时会发生此错误。

但是对于我的应用程序，这种情况是不可能的，因为我在上传文件之前检查了 UI 代码中的文件大小。

这是我的文件上传控制器：

@RequestMapping(value = "fileUpload", method = RequestMethod.POST)
public ResponseEntity<?> uploadFile(@RequestParam("uploadedFile") MultipartFile uploadedFile,
                                    PersistentEntityResourceAssembler resourceAssembler) throws IOException {

    if (uploadedFile.getSize() / 1024 > MAX_FILE_SIZE) {
        throw new CustomConstraintViolationException("File Size exceeds 25 MB");
    }

    //save file

    return new ResponseEntity<>(resourceAssembler.toResource(savedFile), HttpStatus.CREATED);
}

我也在 application.properties 中指定了文件大小。

spring.http.multipart.max-file-size=26240KB
spring.http.multipart.max-request-size=26240KB

那么我做错了什么？

更新

我正在使用 Spring Boot 1.5.17

Answer 1

您可以在此处检查以下application.properties是否正确配置与multipart相关

MULTIPART (MultipartProperties)

spring.servlet.multipart.enabled=true # Whether to enable support of multipart uploads.
spring.servlet.multipart.file-size-threshold=0B # Threshold after which files are written to disk.
spring.servlet.multipart.location= # Intermediate location of uploaded files.
spring.servlet.multipart.max-file-size=1MB # Max file size.
spring.servlet.multipart.max-request-size=10MB # Max request size.
spring.servlet.multipart.resolve-lazily=false # Whether to resolve the multipart request lazily at the time of file or parameter access.

提问者所述的错误（已解决）是（只是引用他的评论）

我检查了 UI 中的 axios 请求，结果发现文件上传设置了 5 分钟超时。 因此，如果超过 5 分钟，请求就会被取消，这会导致连接重置问题。

Answer 2

将下面给定的配置放在属性文件中

spring.servlet.multipart.max-file-size=25MB
spring.servlet.multipart.max-request-size=25MB

而不是

spring.http.multipart.max-file-size=26240KB spring.http.multipart.max-request-size=26240KB

它应该可以解决您的问题。

Answer 3

对于任何有同样问题的人，我发现这个错误是由 UI 文件上传设置的超时引起的，它与 Spring 无关。 现在这可能不适用于此错误的所有实例，因此也请查看本文。
