SpringBoot整合OAuth2.0看完你就会了！

OAuth 2.0是一种开放的授权协议，它允许用户授权第三方应用访问其账户（或资源），而无需共享其用户账户凭据。在Spring Boot中，我们可以使用Spring Security的OAuth2.0模块来实现授权验证。

    private String privateKey;

    @Value("${password}")
    private String password;

    }

    @Bean

配置UserDetailsService

/**

 * @since 2023/6/20 11:47
 */
@Component
public class MyUserDetailsService implements UserDetailsService {

    @Autowired
    private PasswordEncoder passwordEncoder;

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        return new User("admin", passwordEncoder.encode("123456"),
                AuthorityUtils.createAuthorityList("role_admin"));
    }
}
