注册账号后，后台查询数据库发现还是明文存储密码，并没有被加密

@Bean  

public PasswordEncoder passwordEncoder() {  

    return new BCryptPasswordEncoder();   // 使用 BCrypt 加密

} 

@Bean  

public AuthenticationProvider authenticationProvider() {  

    DaoAuthenticationProvider authenticationProvider = new DaoAuthenticationProvider();

    authenticationProvider.setUserDetailsService(userDetailsService);

authenticationProvider.setPasswordEncoder(passwordEncoder); // 设置密码加密方式

    return authenticationProvider;  

} 

/**

* 认证信息管理

* @param auth

* @throws Exception

*/

@Autowired

public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {

    auth.userDetailsService(userDetailsService);

    auth.authenticationProvider(authenticationProvider());

}
