Springboot skips auto-configure the WebMvcAutoConfiguration, because it finds that there is org.springframework.web.servlet.config.annotation.DelegatingWebMvcConfiguration bean, and why did that bean instantiate because the user had @EnableWebMvc annotation on a @Configuration class. This is really screwed up.

WebMvcAutoConfiguration: Matched: - @ConditionalOnClass found required classes 'jakarta.servlet.Servlet', 'org.springframework.web.servlet.DispatcherServlet', 'org.springframework.web.servlet.config.annotation.WebMvcConfigurer' (OnClassCondition) - found 'session' scope (OnWebApplicationCondition) Did not match: - @ConditionalOnMissingBean (types: org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport; SearchStrategy: all) found beans of type 'org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport' org.springframework.web.servlet.config.annotation.DelegatingWebMvcConfiguration (OnBeanCondition)
