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

Question

加密

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

Spring 安全配置

@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();
}
