SecurityConfiguration required bean of type BCryptPasswordEncoder-CodePudding

I tried looking at a couple similar questions however, seems they use different methods/class structures

I'm also using Lombok (not sure if this is an issue)

Here is the error:

Parameter 1 of constructor in com.example.javaspringboot.Security.SecurityConfiguration required a bean of type 'org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder' that could not be found.

Action:

Consider defining a bean of type 'org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder' in your configuration.

The class it references is the following:

@Configuration @EnableWebSecurity @RequiredArgsConstructor
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {

    private final UserDetailsService uds; // VERIFY LOGIN ATTEMPTS
    private final BCryptPasswordEncoder bcpe; // ENCODING PASSWORDS

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(uds).passwordEncoder(bcpe);
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
//        super.configure(http); //USES COOKIES LOOK MORE INTO THIS
        http.csrf().disable();
        http.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);
        http.authorizeRequests().anyRequest().permitAll();
        http.addFilter(new CustomAuthenticationFilter(authenticationManagerBean()));
    }

    @Bean
    @Override
    public AuthenticationManager authenticationManagerBean() throws Exception{ // NO IDEA 
        return super.authenticationManagerBean();
    }

}

The only other class it is being used is in the main application class, as shown:


@SpringBootApplication
public class JavaSpringBootApplication {
    // this runs on init
    public static void main(String[] args) {
        SpringApplication.run(JavaSpringBootApplication.class, args);
    }

    @Bean
    PasswordEncoder passwordEncoder(){ // NEEDED TO ALLOW PASSWORD ENCODER INSIDE SECURITY
        return new BCryptPasswordEncoder();
    }
        };
    }
}

It's a little confusing considering the class it specifies already has @Bean outlined.

Any suggestions are appreciated.

CodePudding user response：

In your main class, the return type is wrong (or you need to change the class in your security config).

public class SecurityConfiguration extends WebSecurityConfigurerAdapter {
    ...
    private final BCryptPasswordEncoder bcpe;
    ...
}

Requires BCryptPasswordEncoder. However

public class JavaSpringBootApplication {
    @Bean
    PasswordEncoder passwordEncoder(){ // NEEDED TO ALLOW PASSWORD ENCODER INSIDE SECURITY
        return new BCryptPasswordEncoder();
    }
}

return PasswordEncoder.

So, either change return type of your bean to BCryptPasswordEncoder or autowire PasswordEncoder in your config.
