Rest Endpoint with Springt Boot 3.0.0 not working anymore - spring

Question

Recently, I updated my dependencies of my Spring Boot Project to 3.0.0 and my rest end points stopped working.
My pom.xml looks like this
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

</configuration>
</plugin>
</plugins>
</build>
</project>
My Resource looks likte that:
#RestController
#RequestMapping(path = "/test")
public class TestResource {
#GetMapping(value="/test")
public ResponseEntity<String> test() {
return ResponseEntity.ok("success");
}
}
Using Spring Boot 2.6.4 the rest end point works. Using Spring Boot 3.0.0 I get a 404 but no errors in the console. What am I missing?
Any hint is appreciated.

Spring Boot 3 requires a JakartaEE Servlet container. That means, for Tomcat, that needs to be at least version 10.x, anything lower is still JavaEE.
