Cannot resolve symbol 'WebSecurityConfigurerAdapter' - Method does not override method from its superclass

Question

I am encountering an issue in my Spring Security configuration where the compiler cannot resolve the symbol 'WebSecurityConfigurerAdapter'. Additionally, I am facing errors stating that methods do not override methods from their superclass. The relevant code snippet is as follows:

package com.shubham.dev.discoveryserver.config;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.Customizer;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.crypto.password.NoOpPasswordEncoder;

@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Value("${app.eureka.username}")
    private String username;
    @Value("${app.eureka.password}")
    private String password;

    @Override
    public void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.inMemoryAuthentication()
                .passwordEncoder(NoOpPasswordEncoder.getInstance())
                .withUser(username).password(password)
                .authorities("USER");
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.csrf(csrf->csrf.disable())
                .authorizeRequests().anyRequest()
                .authenticated()
                .and()
                .httpBasic(Customizer.withDefaults());
    }
}

SpringBoot Version: 3.2.1

ERROR:

I guess the spring-boot version that you are using is 3.x and started from this version the WebSecurityConfigurerAdapter was removed and you have to follow next one article to replace deprecated/removed things spring-security-without-the-websecurityconfigureradapter

Also Configuration part of documentation that will help you to get rid of old configuration.

Here on stackOverflow are a lot of related topic about this kind of migration. As a start you can check my related answer to this question updating-to-latest-spring-security-replacing-deprecated-methods
