首先我们要知道什么是Spring Boot，这里简单说一下，Spring Boot可以看作是一个框架中的框架-集成了各种框架，像security、jpa、data、cloud等等，它无须关心配置可以快速启动开发，有兴趣可以了解下自动化配置实现原理,本质上是 spring 4.0的条件化配置实现，深抛下注解，就会看到了。.

Uploading a file with Spring MVC is pretty easy, and it gets even easier when running in Spring Boot. However, it’s one of the tasks a developer does once in a while and therefore is pretty easy to forget. The page is a reminder for all of us.

Uploading File

We are presenting the demo for single and multiple file upload. We are using XML less configurations. MultipartConfigElement Bean needs to be configured for file upload. In controller, method argument should be MultipartFile class for uploading the file. The JSP form, enctype must be set for multipart form data. Check the demo now. Just execute brew update and try again. 10.2.4 MacPorts installation If you are on a Mac and using MacPorts, all you need to do to install the Spring Boot CLI is: $ sudo port install spring-boot-cli 10.2.5 Command-line completion Spring Boot CLI ships with scripts that provide command completion for BASH and zsh shells.

For uploading a file, you must use multipart/form-data as the form encoding and usually files are uploaded with a POST request.

On the Spring MVC @Controller we only need to add a @RequestParam with the name of your form field and map it to a MultipartFile class.

The MultipartFile class provides access to the file, file name, file type, etc.

Uploading Multiple Files

For uploading multiple files together, we only need to add all the files to the form.

In your form will have multiple instances of file inputs using the same name attribute. The browser will include them all in the request.

In the @Controller, we can simply switch from a single MultipartFile parameter to using a MultipartFile array.

In Spring Boot the Multipart file upload is configured automatically and set up with defaults. It will also use the Servlet 3 API for Multiparts.

If you need to adjust the max file size or similar, you can do so by setting the following properties in your application.properties.

The most used properties are:

  • spring.http.multipart.file-size-threshold A threshold after which the files are written to disk. Supports MB or KB as suffixes to indicate size in Megabyte or Kilobyte
  • spring.http.multipart.location location of the temporary files
  • spring.http.multipart.max-file-size Max size per file the upload supports; also supports the MB or KB suffixes; by default 1MB
  • spring.http.multipart.max-request-size max size of the whole request; also supports the MB or KB suffixes
