This article mainly introduces how to solve the problem of spring boot uploadfileerror. The example code is introduced in detail in this article, which has a certain reference learning value for everyone’s study or work. You can refer to the following for your friends
There was no test server using the test environment for some time.
Then I want to use the test environment yesterday to upload the files. There was no problem before, but it can’t be used suddenly today. Open the log file and it is found that the error is reported as the above error. Is missing file.
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.velocity.expose-session-attributes=false # Set whether all HttpSession attributes should be added to the model prior to merging with the template. Spring.velocity.expose-spring-macro-helpers=true # Set whether to expose a RequestContext for use by Spring's macro library, under the name 'springMacroRequestContext'. Set file temporary storage path spring.http.multipart.location = /var/tmp. The above is the whole content of this article. I hope it will help you in your study, and I hope you can support developepaer more.
But generally no one cleans up the files on the server.??????
Later, according to the multi-party search, the reason was found. It turns out that the files in TMP directory that have not been used in 10 days will be automatically cleared under Linux. When springboot is started, a Tomcat. * file directory will be generated under / tmp directory for the file stream operation of “Java. Io. TMPDIR”. Because no one operates during the holiday, the Linux system will automatically delete the temporary files, resulting in the upload error
Solution
1、 Temporary solution (fast solution, but not recommended)
Restart the service, and the deleted Tomcat directory will be regenerated
2、 Add startup configuration item (if your app is started by script, consider)
Add parameter – DJava. Io. TMPDIR = custom directory at startup
