Spring Boot + Undertow upload file cannot find temporary directory
The problem occurs
Two days ago, the company’s SpringBoot project suddenly had a problem of being unable to upload Excel files.
After checking the Java log, I found a large number of exceptions: java.nio.file.NoSuchFileException: /tmp/undertow.12020.9432679758080410942/undertow17157208698492118168upload
Detailed exception information is as follows:
org.springframework.web.multipart.MultipartException: Failed to parse multipart servlet request; nested exception is java.lang.RuntimeException: java.nio.file.NoSuchFileException: /tmp/undertow.12020.9432679758080410942/undertow17157208698492118168upload

Error reason
In a Linux system, when the Spring Boot application is started with the java -jar command, a tomcat (or undertow) will be generated in the /tmp directory of the operating system. The uploaded file must first be converted into a temporary file and saved in this folder. Because the files in the temporary /tmp directory are not used for a long time (10 days), they will be automatically deleted by the system mechanism. Therefore, if the system has not used the temporary folder for a long time, it may cause the above problem.
Solution
Method 1: Temporary solution
Restart the SpringBoot application to solve the problem immediately.
Method 2: Modify application.yml
Add the configuration spring.servlet.multipart.location to the configuration file applicaiton.yml and set it to a fixed upload file directory.
