如何在spring boot项目中使用Spring Security的BCryptPasswordEncoder类进行相同密码不同密文的加密和验证

<!--加密模块-->

@Bean
    public BCryptPasswordEncoder getBcryptPasswordEncoder(){
        return new BCryptPasswordEncoder();
    }

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.web.SecurityFilterChain;
@Configuration
public class SecurityConfig {
    @Bean
    public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {
        http.csrf().disable()
                .authorizeRequests()
                .anyRequest().permitAll();
        return http.build();
    }
}

private BCryptPasswordEncoder bCryptPasswordEncoder = new BCryptPasswordEncoder();

encodePassWord = bCryptPasswordEncoder.encode(passWord);

bCryptPasswordEncoder.matches(password, encodePassWord)
