Error creating bean with name 'springSecurityConfig': Requested bean is currently in creation: Is there an unresolvable circular reference?

Question

I got error in encoding my inMemory User password using BCryptPasswordEncoder

here is my springsecurityconfig file

SpringSecurityConfig class

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.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;

@Configuration
@EnableWebSecurity
public class SpringSecurityConfig extends WebSecurityConfigurerAdapter {

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


    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
        auth.inMemoryAuthentication()
                .withUser("admin")
                .password(passwordEncoder().encode("password"))
                .roles("USER");
    }

    @Bean
    public PasswordEncoder passwordEncoder(){
        return new BCryptPasswordEncoder();
    }


}

How can i properly encode the password without getting bean creation error

please enable spring security debug logs and post your full logs here pls — Toerktumlare, Mar 24 '22 at 22:24

You can use a more component-based approach to do that since the WebSecurityConfigurerAdapter has been deprecated in 5.7.0-M2.

@Configuration
@EnableWebSecurity
public class SpringSecurityConfig {

    @Bean
    public SecurityFilterChain appSecurity(HttpSecurity http) throws Exception {
        http
                .csrf().disable()
                .authorizeRequests()
                .anyRequest()
                .authenticated()
                .and()
                .httpBasic();
        return http.build()
    }

    @Bean
    public UserDetailsService userDetailsService(PasswordEncoder encoder) {
        User admin = User.withUsername("admin")
            .password(encoder.encode("password"))
            .roles("USER").build();
        return new InMemoryUserDetailsManager(admin);
    }

    @Bean
    public PasswordEncoder passwordEncoder(){
        return new BCryptPasswordEncoder();
    }


}

This way, you have in-memory authentication by providing a InMemoryUserDetailsManager as the implementation of UserDetailsService, and this bean is dependent on the PasswordEncoder.

You can find more detail on the reference docs.

he has not stated he is using any form of prerelease – Toerktumlare Mar 24 '22 at 22:23
Where did I recommend they to use the prerelease? – Marcus Hert da Coregio Mar 25 '22 at 00:59
M = Milestone release, is not a full stable release https://stackoverflow.com/a/2107490/1840146 current stable version at the time of writing is 5.6.4 – Toerktumlare Mar 25 '22 at 08:14
Still I don't see my recommendation to use the milestone. I just stated that the class is gonna be deprecated in the future and a more robust solution is available for them – Marcus Hert da Coregio Mar 25 '22 at 12:29
As of time of writing, the class is not deprecated – Toerktumlare Mar 25 '22 at 21:00

Create a separate configuration class and move passwordEncoder() method to it.

Example:

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;

@Configuration
public class PasswordEncoderConfig {

    @Bean
    PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }

}

And then modify SpringSecurityConfig as below:

@Configuration
@EnableWebSecurity
public class SpringSecurityConfig extends WebSecurityConfigurerAdapter {

 @Autowired
 private PasswordEncoder passwordEncoder; //new line

 @Autowired
 public void configureGlobal(AuthenticationManagerBuilder authentication) throws Exception {
    authentication.inMemoryAuthentication()
      .withUser("admin")
      .password(passwordEncoder.encode("password")) //update line
      .roles("USER");
    }
}
