Spring Boot AuthenticationManagerBean does not work

Question

In my project when I am trying to define the bean for AuthenticationManager by overriding the AuthenticationManagerBean() method it is showing the below error,

The method authenticationManagerBean() of type SecurityConfiguration must override or implement a supertype method

While the method I am defining is given below,

 @Bean(name = BeanIds.AUTHENTICATION_MANAGER)
 @Override
 public AuthenticationManager authenticationManagerBean() throws Exception {
    return super.authenticationManagerBean();
 }

My entire SecurityConfiguaration class is given below,

package com.toorjaridwan.introvertreadersauth.Configuration;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.config.BeanIds;
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.EnableWebSecurity;
import org.springframework.security.crypto.password.NoOpPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;

import com.toorjaridwan.introvertreadersauth.Service.UserDetailService;

@Configuration
@EnableWebSecurity
public class SecurityConfiguration {

    @Autowired
    private UserDetailService userDetailService;

    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(userDetailService);
    }

    protected void configure(HttpSecurity http) throws Exception {
        http.csrf().disable().authorizeRequests().antMatchers("/authenticate").permitAll()
        .anyRequest().authenticated();
    }

       @Bean(name = BeanIds.AUTHENTICATION_MANAGER)
       @Override
       public AuthenticationManager authenticationManagerBean() throws Exception {
           return super.authenticationManagerBean();
       }

    @Bean
    public PasswordEncoder passwordEncoder() {
        return NoOpPasswordEncoder.getInstance();
    }

}

In a previous project which used Spring Boot version 2.1.9, everything went smoothly, no issue at all. Now I am using Spring Boot version 2.2.6. I do not know if it is the reason.

When searching for solution I came across this and this. I found things to be as similar as I did.

I am running a 64 bit Ubuntu 16.04 LTS and Java version 1.8

try adding

extends WebSecurityConfigurerAdapter

to your configuration class

WebSecurityConfigurerAdapter is now deprecated, what do we do now that the security config doesn't extend WebSecurityConfigurerAdapter? – Phong Phuong Jun 19 '22 at 23:52
@PhongPhuong Read up on this document, https://spring.io/blog/2022/02/21/spring-security-without-the-websecurityconfigureradapter – lane.maxwell Jun 20 '22 at 00:18
I did look at that but there bits and pieces of code missing in the examples. I followed this and fixed the AuthenticationManagerBean(): https://stackoverflow.com/questions/72381114/spring-security-upgrading-the-deprecated-websecurityconfigureradapter-in-spring – Phong Phuong Jun 20 '22 at 00:35
