Spring上传文件大小限制错误

Question

我正在使用 Spring Boot，我可以发送小于 1MB 的图像，但是当我使用大于 1MB 的大图像发出发布请求时，我收到此错误：

Maximum upload size exceeded; nested exception is java.lang.IllegalStateException:org.apache.tomcat.util.
http.fileupload.FileUploadBase$FileSizeLimitExceededException: The field file exceeds its maximum permitted size of 1048576 bytes.

我一直在四处寻找这个错误的答案。我查看了所有这些问题并尝试实施他们的建议无济于事：Spring upload file size limit， I am trying to set maxFileSize but it is not honored、org.apache.tomcat.util.http.fileupload.FileUploadBase$FileSizeLimitExceededException 和 Max Limit of MultipartFile in spring boot

我使用的是 Spring 2.0.3 版本，这是我的帖子映射：

    @PostMapping("/post")
    public ResponseEntity<String> handleFileUpload(@RequestParam("file") MultipartFile file) {
      String message = "";
      try {
        storageService.store(file);
        files.add(file.getOriginalFilename());

        message = "You successfully uploaded " + file.getOriginalFilename() + "!";
        return ResponseEntity.status(HttpStatus.OK).body(message);
      } catch (Exception e) {
      message = "FAIL to upload " + file.getOriginalFilename() + "!";
      return ResponseEntity.status(HttpStatus.EXPECTATION_FAILED).body(message);
  }

}

以下是我尝试过的所有 application.properties 配置：

1

spring.servlet.multipart.max-file-size=-1
spring.servlet.multipart.max-request-size=-1

2

spring.servlet.multipart.max-file-size=5MB
spring.servlet.multipart.max-request-size=5MB

3

spring.http.multipart.max-file-size=5MB
spring.http.multipart.max-request-size=5MB

4

multipart.max-file-size=5MB
multipart.max-request-size=5MB

5

server.tomcat.max-file-size=5000000

6

server.tomcat.max-http-post-size=5000000

7

spring.servlet.multipart.maxFileSize=-1
spring.servlet.multipart.maxRequestSize=-1

甚至尝试将其更改为 application.yml：

spring:
  servlet:
    multipart:
      max-file-size: 5MB
      max-request-size: 5MB

我还研究了在 web.xml 文件中更改 Tomcat 允许的请求大小，但我没有 web.xml 文件。我正在使用的 Tomcat 捆绑在应用程序中。

Answer 1

在 application.properties 中为 Spring Boot 2.0.0.RELEASE 及更高版本添加以下行 -

spring.servlet.multipart.max-file-size=128MB
spring.servlet.multipart.max-request-size=128MB
spring.servlet.multipart.enabled=true

请注意对于较低版本，即1.5.9.RELEASE及以下之前的配置如下：

spring.http.multipart.max-file-size = 20MB
spring.http.multipart.max-request-size = 20MB

Answer 2

根据最新的Spring Boot Common properties 下面应该可以工作

MULTIPART（多部分属性）

spring.servlet.multipart.enabled=true # Whether to enable support of multipart uploads.
spring.servlet.multipart.file-size-threshold=0 # Threshold after which files are written to disk. Values can use the suffixes "MB" or "KB" to indicate megabytes or kilobytes, respectively.
spring.servlet.multipart.location= # Intermediate location of uploaded files.
spring.servlet.multipart.max-file-size=1MB # Max file size. Values can use the suffixes "MB" or "KB" to indicate megabytes or kilobytes, respectively.
spring.servlet.multipart.max-request-size=10MB # Max request size. Values can use the suffixes "MB" or "KB" to indicate megabytes or kilobytes, respectively.
spring.servlet.multipart.resolve-lazily=false # Whether to resolve the multipart request lazily at the time of file or parameter access.

或者如果您只想控制多部分属性，那么 multipart.max-file-size 和 multipart.max-request-size 属性应该可以工作。

multipart.max-file-size=5MB
multipart.max-request-size=5MB

Answer 3

取决于 Spring boot 版本，例如 1.X，在您的 application.properties 上，设置文件大小限制：

spring.http.multipart.max-file-size=128KB
spring.http.multipart.max-request-size=128KB

Spring Boot 2.x / 以上：

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

Answer 4

这就是我所拥有的，它非常适合我的后端。

@PutMapping(value = USER_PROFILE_UPDATE_URL_MAPPING)
  public String updateProfile(
      @ModelAttribute(AUTHORIZED_USER_MODEL_KEY) User user,
      BindingResult bindingResult,
      @RequestParam(name = "file") MultipartFile multipartFile,
      Model model, @RequestParam Map<String, String> params) {

    Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
    User authorizedUser = (User) authentication.getPrincipal();
    //.... 

      return REDIRECT_TO_LOGIN;
    }

在 bootstrap.yml 文件中，我会简单地有这样的东西...... 这将只允许 2 兆字节的最大文件大小。

---
spring:
  servlet:
    multipart:
      max-file-size: 2MB
      max-request-size: 2MB

最后，在我的 HTML 文件中，我会有这样的东西......

<form id="profileForm"
   th:action="@{/update}"
   th:object="${user}"
   method="post" enctype="multipart/form-data">

   <!-- This will modify the method to PUT to match backend -->
   <input type="hidden" name="_method" value="PUT">

   ...

   <div class="col-md-3">
      <div class="form-group row">
         <label for="file" class="custom-file">
           <input name="file" type="file" id="file" aria-describedby="fileHelpId"  class="form-control-file btn btn-outline-info">
          </label>
          <small id="fileHelpId" class="form-text text-muted">Maximum size should be 2MB</small>
       </div>
   </div>

这应该可以正常工作。我也在使用 Spring Boot 2.0.3

Answer 5

你试过了吗？

spring.http.multipart.maxFileSize = 20MB
spring.http.multipart.maxRequestSize = 20MB

或

spring.http.multipart.max-file-size = 20MB
spring.http.multipart.max-request-size = 20MB

适用于我的 Spring Boot 1.5.x

Answer 6

This worked for me.
We can make changes to file size either in
1. application.properties 2. TOMCAT configuration(server.xml)

A. Ideally we should make use of application.properties 
B. And for that first we need to disable in TOMCAT config file "server.xml" by setting maxSwallowSize=-1 .

    <Connector port="8080" protocol="HTTP/1.1"
      connectionTimeout="20000"
      redirectPort="8443"
      maxSwallowSize = "-1"/>

C. Then set application.properties as

spring.servlet.multipart.max-file-size=15MB
spring.servlet.multipart.max-request-size=15MB
spring.servlet.multipart.enabled=true
