前言
本文主要給大家介紹了關於spring security 5.x實現兼容多種密碼的加密方式，分享出來供大家參考學習，下面話不多說了，來一起看看詳細的介紹吧。
1、spring security PasswordEncoder
spring security 5不需要配置密碼的加密方式，而是用戶密碼加前綴的方式表明加密方式，如：
spring security官方推薦使用更加安全的bcrypt加密方式。
這樣可以在同一系統中支持多種加密方式，遷移用戶比較省事。 spring security 5支持的加密方式在PasswordEncoderFactories中定義：
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 測試

2.2 測試
spring security 5.x默認使用bcrypt加密
@Slf4jpublic class DomainUserDetailsService { public static void main(String[] args){ PasswordEncoder passwordEncoder = PasswordEncoderFactories.createDelegatingPasswordEncoder(); String encode = passwordEncoder.encode("password"); log.info("加密後的密碼:" + encode); log.info("bcrypt密碼對比:" + passwordEncoder.matches("password", encode)); String md5Password = "{MD5}88e2d8cd1e92fd5544c8621508cd706b";//MD5加密前的密碼為:password log.info("MD5密碼對比:" + passwordEncoder.matches("password", encode)); }}總結
