I am using spring-boot 2.6.6 and spring-framework 5.3.18.

The web.xml have

<filter>
    <filter-name>filterChainProxy</filter-name>
    <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>

<filter-mapping>
    <filter-name>filterChainProxy</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

spring-boot
