java - 如果我使用Md5PasswordEncoder进行密码加密，如何在Spring Security Config中配置passwordEncoder？

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。但是我不知道如何在Spring安全配置中配置passwordEncoder（）

最佳答案

@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();
}
