Hi, @itl-coder, thanks for reaching out. I'm going to need a bit more information in order to address your issue. Can you provide a sample unit test that causes BCryptPasswordEncoder to fail how you describe?

You only need to customize a save(User user) in the SpringSecurity environment and encrypt the password field to trigger;

@Data class User{ private String username; private String password; }

---

public static String encodePassword(String password) {
    BCryptPasswordEncoder passwordEncoder = new BCryptPasswordEncoder();
    return passwordEncoder.encode(password);
}

User user = new User(); user.setUsername("zs"); // encrypt password user.setPassword(encodePassword("12345678$")); //
userMapper.save(user);
