Below is my code.
`import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.Customizer;
import org.springframework.security.config.annotation.web.reactive.EnableWebFluxSecurity;
import org.springframework.security.config.web.server.ServerHttpSecurity;
import org.springframework.security.web.server.SecurityWebFilterChain;

@configuration
@EnableWebFluxSecurity
public class SecurityConfig {

@Bean
public SecurityWebFilterChain securityFilterChain(ServerHttpSecurity serverHttpSecurity) {
    serverHttpSecurity.csrf(ServerHttpSecurity.CsrfSpec::disable)
            .authorizeExchange(exchange -> exchange
                    .pathMatchers("/eureka/**")
                    .permitAll()
                    .anyExchange()
                    .authenticated())
            .oauth2ResourceServer(oAuth2ResourceServerSpec -> oAuth2ResourceServerSpec.jwt(Customizer.withDefaults()));

    return serverHttpSecurity.build();
}

}`

Can anyone please help me resolve this issue.

ClassNotFound generally means that there is a mismatch in a dependency version.

Make sure you have the same code as the GitHub repo, and delete your .m2/repository folder, in this way, maven re-downloads the dependencies and it should work.
