如何从BCryptPasswordEncoder获取原始密码

import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;

public class PasswordEncoderExample {
    public static void main(String[] args) {
        String rawPassword = "password123";
        
        BCryptPasswordEncoder encoder = new BCryptPasswordEncoder();
        String encodedPassword = encoder.encode(rawPassword);
        
        System.out.println("Encoded Password: " + encodedPassword);
        
        boolean isMatch = encoder.matches(rawPassword, encodedPassword);
        System.out.println("Password Match: " + isMatch);
    }
}
