        BCryptPasswordEncoder passwordEncoder = new BCryptPasswordEncoder();
        //$2a$10$yPM6IkqoB8IToGKALlk6BOsp4G2eCc2hahwT5JSTzq0dwjGFXk0Pu
        //$2a$10$VIycWJctonDmydQIJa51AuOE9pu.lZIUSFX3Kp3LiMHsZjI65xkhW
        String encode = passwordEncoder.encode("123456");
        System.out.println("密码加密：" + encode);
        //判断密码是否一致
        boolean matches = passwordEncoder.matches("123456", "$2a$10$yPM6IkqoB8IToGKALlk6BOsp4G2eCc2hahwT5JSTzq0dwjGFXk0Pu");
        System.out.println("密码是否一致：" + matches);

passwordEncoder.encode 每次加密结果都会不相同
passwordEncoder.matches 结束明文密码再去数据库查询上次的加密值去做比对
