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：
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 测试

2.2 测试
spring security 5.x默认使用bcrypt加密
@Slf4jpublic 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)); }}总结
