>Solution :

You need to downgrade the Servlet API to 5.0 as Jetty 11 does not support Servlet 6.0. Assuming that you’re using spring-boot-starter-parent, you can do so by setting a property in your pom.xml:

<properties>
    <jakarta-servlet.version>5.0.0</jakarta-servlet.version>
</properties>

That said, unless you really have to use Jetty, I would recommend sticking with the default Tomcat web server as it supports Servlet 6.0.
