 @Bean
    PasswordEncoder encoder(){
        return  new BCryptPasswordEncoder();
    }

自定义UserDetailsService

@Service
public class UserDetailsServiceImpl implements UserDetailsService {
    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        if (!"zhangsan".equals(username)){
            return null;
        }
        return User.builder()
                .username(username)
                .password("$2a$10$Dqn398CCfmv47tvaR3kMvOJ/1UQ9dTDZC4baqg0AqClqyiwJBeDVq")
                .roles("USER")
                .build();
    }
}
// 密码通过BCrypt加密获取
// System.out.println("密码："+new BCryptPasswordEncoder().encode("123456"));
