如果我使用Md5PasswordEncoder进行密码加密,如何在spring security config中配置passwordEncoder？

Question

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;
    }

我需要使用org.springframework.security.authentication.encoding.Md5PasswordEncoder进行密码加密.但我不知道如何在Spring安全配置中配置passwordEncoder()

Answer 1

@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth
                .userDetailsService(customUserDetailsService)
                .passwordEncoder(passwordEncoder());
    }
}



@Bean
public PasswordEncoder passwordEncoder(){
    //implements PasswordEncoder and overide encode method with the MD5 protocol
    return new MD5PasswordEncoder();
}

安全配置

                    @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 实现

        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);
            }

        }
