integrate spring security and spring MVC and and spring integration with each other - spring

Question

I am currently developing a web site for having control over IOT devices by spring.
The application is based on spring boot.
I have developed most of rest API s by extending from DataJpa.
Next step I had to implement TCP connection in my application and after doing some
research I adopt spring integration for doing that and simple application worked well.
Next, I decided to add spring Integration to my application for only user authentication after that I configured that I realized that there are some conflicts
in my application and I received java: cannot access javax.servlet.Filter class file for javax.servlet.Filter not found.
I did some research in I found a related topic for spring webflux and it was said that I should implement spring security for webflux (integration in this case) not for spring web.
Now about the main problem: as I said earlier the structure of application should be like this:
1- first part which is MVC based and there are some webpages and data should be stored in mySql or mariaDB, also i want to authenticate and authorize users by spring security.
2-Second part of application is implementation Tcp socket via Netty or spring integration for having an an alive connection between IOT devices and Server.
Now I am looking for a way to be able to say to spring that it should distinguish
these two different contexts from each other and not combine configurations with the other one while they must work with each other.
Is there any way for this separation and tell spring combine them with special responsible for each?

.antMatchers("/","/home").permitAll()
.and().formLogin();
}
#Bean
public BCryptPasswordEncoder bCryptPasswordEncoder() {
return new BCryptPasswordEncoder();
}
}
error which occurs :
java: cannot access javax.servlet.Filterclass file for javax.servlet.Filter not found
and points to first line of spring security configuration.
my application properties:
spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp

/C:/Users/s.movahedi/Downloads/t1/demo/src/main/java/com/example/demo/security/securityConfig.java:[17,8] cannot access javax.servlet.Filter [ERROR] class file for javax.servlet.Filter not found
So it's your demo app that needs to be changed to use jakarta instead of javax if you want to use Boot 3, Spring 6.
