[FIXED] How to configure passwordEncoder in spring security config if i use Md5PasswordEncoder for password encryption?

Issue

Encryption

Md5PasswordEncoder md5PasswordEncoder = new Md5PasswordEncoder();
md5PasswordEncoder.encodePassword(
    userRegistrationInfo.getPassword(), 
    AppConstants.MD5_PASSWORD_ENCODER_SALT);

Spring Security Configuration

@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception { 
 
   auth
      .userDetailsService(userDetailsService)
      .passwordEncoder(passwordEncoder());
}
    
@Bean
public PasswordEncoder passwordEncoder() {
    PasswordEncoder encoder = new BCryptPasswordEncoder();
    return encoder;
}
    

I need to use org.springframework.security.authentication.encoding.Md5PasswordEncoder for my password encryption. But I don't know how to configure passwordEncoder() in Spring security configuration.

Solution

                    @Autowired
                    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
                        auth.userDetailsService(userDetailsService).passwordEncoder(passwordEncoder());
                    }


            @Bean
                public PasswordEncoder passwordEncoder(){
                    PasswordEncoder encoder = new FlasherPasswordEncoder();
                    return encoder;
                }

PasswordEncoder MyOwn Implementation

        package com.flasher.config;

        import org.springframework.security.authentication.encoding.Md5PasswordEncoder;
        import org.springframework.security.crypto.password.PasswordEncoder;

        public class FlasherPasswordEncoder implements PasswordEncoder {

            @Override
            public String encode(CharSequence rawPassword) {
                return new Md5PasswordEncoder().encodePassword(rawPassword.toString(), AppConstants.MD5_PASSWORD_ENCODER_SALT);

            }

            @Override
            public boolean matches(CharSequence rawPassword, String encodedPassword) {
                return new Md5PasswordEncoder().encodePassword(rawPassword.toString(), AppConstants.MD5_PASSWORD_ENCODER_SALT)
                        .equals(encodedPassword);
            }

        }
