BCryptPasswordEncoder的matches方法返回false

用BCryptPasswordEncoder 做加密，在判断时要用该对象的matches方法，第一个参数为明文！！！，第二个参数才是密文 ！！！

  public static void main(String[] args) {

        BCryptPasswordEncoder passwordEncoder = new BCryptPasswordEncoder();

        String encode = passwordEncoder.encode("123");
        String encode1 = passwordEncoder.encode("123");

        boolean matches = passwordEncoder.matches("123", encode); //true
        boolean matches1 = passwordEncoder.matches("123", encode1); //true
        boolean matches2 = passwordEncoder.matches(encode,encode1); //false

        System.out.println(matches);
        System.out.println(matches1);
        System.out.println(matches2);
    }
