Getting error as "The method filterChain(HttpSecurity) of type SecurityConfig must override or implement a supertype method" - spring

Question

I am getting error as
The method filterChain(HttpSecurity) of type SecurityConfig must override or implement a supertype method
My code are
SecurityConfig.java
#Configuration
#EnableWebSecurity
public class SecurityConfig{
#Autowired private AuthSecurity filter;
#Bean
protected SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
http.csrf().disable()
.httpBasic().disable()
.cors()
.and()
.authorizeRequests()
.antMatchers("/prod/api/v1/open/status").permitAll()
.antMatchers("/prod/api/v1/open/**").authenticated()
.and()
.exceptionHandling()
.authenticationEntryPoint(
(request, response, authException) ->
response.sendError(HttpServletResponse.SC_UNAUTHORIZED, "Unauthorized")
)
.and()
.sessionManagement()
.sessionCreationPolicy(SessionCreationPolicy.STATELESS);
http.addFilter(filter);
return http.build();
}
}
AuthSecurity.java
#Component
public class AuthSecurity extends OncePerRequestFilter{
#Override
#ResponseBody
public void doFilterInternal(HttpServletRequest request,HttpServletResponse response,FilterChain filterChain) throws ServletException, IOException
{
String authHeader = response.getHeader("Authorization");
if(authHeader != null && authHeader.length()>0 && authHeader.startsWith("Bearer "))
{
String jwt = authHeader.substring(7);
if(jwt == null || jwt.length()==0){
response.sendError(HttpServletResponse.SC_BAD_REQUEST, "Invalid Token in Bearer Header");
}
else
{ if(SecurityContextHolder.getContext().getAuthentication() == null && jwt.equals("asd123")){ SecurityContextHolder.createEmptyContext();
}
else{
response.sendError(HttpServletResponse.SC_BAD_REQUEST, "Invalid Token");
}
}
}
}
I just want to check if the Header token matches my personal token and if it is allow it to visit other endpoints.
The error log is

Description:
Parameter 0 of method filterChain in com.company.framework.Security.SecurityConfig required a bean of type 'org.springframework.security.config.annotation.web.builders.HttpSecurity' that could not be found.
Action:
Consider defining a bean of type 'org.springframework.security.config.annotation.web.builders.HttpSecurity' in your configuration.
I have just started working on Spring boot, so I am not able to understand the things that are going back in there. If you have any ideas or documentation to easily understand all these things, iT would be great.
Before questioning, I looked through
Spring Security: Upgrading the deprecated WebSecurityConfigurerAdapter in Spring Boot 2.7.0
But the solution there isn't working for me.
