前言

本文主要给大家介绍了关于spring security 5.x实现兼容多种密码的加密方式，分享出来供大家参考学习，下面话不多说了，来一起看看详细的介绍吧。

1、spring security PasswordEncoder

spring security 5不需要配置密码的加密方式，而是用户密码加前缀的方式表明加密方式，如：

{MD5}88e2d8cd1e92fd5544c8621508cd706b代表使用的是MD5加密方式；
{bcrypt}$2a$10$eZeGvVV2ZXr/vgiVFzqzS.JLV878ApBgRT9maPK1Wrg0ovsf4YuI6代表使用的是bcrypt加密方式。

spring security官方推荐使用更加安全的bcrypt加密方式。

这样可以在同一系统中支持多种加密方式，迁移用户比较省事。spring security 5支持的加密方式在PasswordEncoderFactories中定义：

public class PasswordEncoderFactories {
 public static PasswordEncoder createDelegatingPasswordEncoder() {
  String encodingId = "bcrypt";
  Map<String, PasswordEncoder> encoders = new HashMap();
  encoders.put(encodingId, new BCryptPasswordEncoder());
  encoders.put("ldap", new LdapShaPasswordEncoder());
  encoders.put("MD4", new Md4PasswordEncoder());
  encoders.put("MD5", new MessageDigestPasswordEncoder("MD5"));
  encoders.put("noop", NoOpPasswordEncoder.getInstance());
  encoders.put("pbkdf2", new Pbkdf2PasswordEncoder());
  encoders.put("scrypt", new SCryptPasswordEncoder());
  encoders.put("SHA-1", new MessageDigestPasswordEncoder("SHA-1"));
  encoders.put("SHA-256", new MessageDigestPasswordEncoder("SHA-256"));
  encoders.put("sha256", new StandardPasswordEncoder());
  return new DelegatingPasswordEncoder(encodingId, encoders);
 }
 private PasswordEncoderFactories() {
 }
}

2.2 测试

spring security 5.x默认使用bcrypt加密

@Slf4j
public class DomainUserDetailsService {
 public static void main(String[] args){
  PasswordEncoder passwordEncoder = PasswordEncoderFactories.createDelegatingPasswordEncoder();
  String encode = passwordEncoder.encode("password");
  log.info("加密后的密码:" + encode);
  log.info("bcrypt密码对比:" + passwordEncoder.matches("password", encode));
  String md5Password = "{MD5}88e2d8cd1e92fd5544c8621508cd706b";//MD5加密前的密码为:password
  log.info("MD5密码对比:" + passwordEncoder.matches("password", encode));
 }
}
