One option is to try the following methods to clear the cache in Tomcat within Spring Boot.

To clear Tomcat’s temporary folder, locate the temporary folder within the Tomcat installation directory (usually found in the /work/Catalina/localhost/ directory) and manually delete the files within it.
Clear Tomcat’s log files: Tomcat’s log files may occupy a large amount of disk space. You can try clearing these log files to free up space.
Restarting the Tomcat server can help clear its cache, reload applications, and clear the cache.
Modify the configuration file of Tomcat: You can try adjusting the configuration file of Tomcat, such as the cachingAllowed attribute in the server.xml file, to control the behavior of caching.
Refresh dynamically using Spring Boot Actuator: You can utilize the endpoints provided by Spring Boot Actuator to refresh Tomcat’s cache dynamically. Accessing the /actuator/refresh endpoint can force the Spring Boot application to reload configurations and clear the cache.

It is important to note that clearing the Tomcat cache may result in some performance loss or application restart, so it is recommended to perform this operation in a non-production environment.
