使用 Spring Session Redis 时身份验证主体为空答案

【问题标题】：Authentication Principal is empty while using Spring Session Redis使用 Spring Session Redis 时身份验证主体为空
【发布时间】：2016-07-30 06:08:56
【问题描述】：

我正在使用 Spring Boot v1.3.3 构建 rest API。 API 由 Spring Security 保护。我已经实现了自定义用户详细信息服务，以便在身份验证上下文中拥有自定义主体。

我需要与其他 Spring 应用程序共享 API 会话，因此我选择使用本教程在我的应用程序中使用 Redis 服务器实现 Spring Session docs.spring.io/spring-session/docs/current/reference/html5 /guides/security.html。不幸的是，它导致身份验证主体停止工作。当我试图通过注释@AuthenticationPrincipal CustomUserDetails user 或SecurityContextHolder.getContext().getAuthentication().getPrincipal() 获取当前主体时，它返回我的自定义用户详细信息，但Id = 0 和所有字段设置为null (screen from debugging)。我什至无法从SecurityContextHolder.getContext().getAuthentication().getName() 获取用户名。

在我评论 Redis 代码和 maven 依赖项后，它可以工作 (see debug screen)。如何让它与 Spring Session 和 Redis 服务器一起工作？

这是应用程序中的一些代码：

检查 Principal 的一些示例方法

@RequestMapping(value = "/status", method = RequestMethod.GET)
public StatusData status(@AuthenticationPrincipal CustomUserDetails user) {
    User user2 = (CustomUserDetails) SecurityContextHolder.getContext().getAuthentication().getPrincipal();
    if (user != null) {
        String name = user.getUsername();
        return new StatusData(name);
    } else return new StatusData(null);
}

应用程序和 Redis 配置：

@Configuration
@EnableRedisHttpSession
public class AppConfig {

    @Bean
    public JedisConnectionFactory connectionFactory() {
        return new JedisConnectionFactory();
    }

    @Bean
    public CookieSerializer cookieSerializer() {
        DefaultCookieSerializer serializer = new DefaultCookieSerializer();
        serializer.setCookieName("JSESSIONID");
        serializer.setCookiePath("/");
        serializer.setDomainNamePattern("^.+?\\.(\\w+\\.[a-z]+)$");
        return serializer;
    }

    @Bean
    public ShaPasswordEncoder shaEncoder() {
        return new ShaPasswordEncoder(256);
    }

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

    @Bean(name = "messageSource")
    public ResourceBundleMessageSource messageSource() {
        ResourceBundleMessageSource resourceBundleMessageSource = new ResourceBundleMessageSource();
        resourceBundleMessageSource.setBasename("messages/messages");
        return resourceBundleMessageSource;
    }

    @Bean
    public Validator basicValidator() {
        LocalValidatorFactoryBean validator = new LocalValidatorFactoryBean();
        validator.setValidationMessageSource(messageSource());
        return validator;
    }

    public AppConfig() {
        DateTimeZone.setDefault(DateTimeZone.UTC);
    }
}

初始化器（用于 Redis 会话）

public class Initializer extends AbstractHttpSessionApplicationInitializer {

}

SecurityInitializer（用于 Redis 会话）

public class SecurityInitializer extends AbstractSecurityWebApplicationInitializer {

    public SecurityInitializer() {
        super(WebSecurityConfig.class, AppConfig.class);
    }
}

WebSecurityConfig（Spring 安全配置）

@Configuration

    private AuthFailureHandler authFailureHandler;

    @Autowired
    private HttpLogoutSuccessHandler logoutSuccessHandler;

    @Autowired
    private BCryptPasswordEncoder bCryptPasswordEncoder;

    /**

    @Bean
    public PersistentTokenRepository tokenRepository() {
        JdbcTokenRepositoryImpl db = new JdbcTokenRepositoryImpl();
        db.setDataSource(dataSource);

    }

        rememberMeServices.setAlwaysRemember(true);
        rememberMeServices.setTokenValiditySeconds(1209600);
        return rememberMeServices;
    }

【问题讨论】：

标签： java spring spring-security redis spring-session

【解决方案1】：

我解决了这个问题。原来，Spring-Session 序列化了 Principal 对象。我的 UserDetails 自定义实现是 Hibernate Model User 类的子类。我通过在我的自定义 UserDetails、User 模型和该模型中使用的所有类中实现 Serializable 接口来解决它。

【讨论】：

我还有一个自定义的UserDetails，我改成实现Serializable（公共类MyUserDetails扩展了org.springframework.security.core.userdetails.User实现了Serializable）。我使用带有 JDBC 后端的 Spring Session，但列 principal_name 为 NULL。奇怪。
我同意@yglodt，这可能不是一个好的答案。如果您查看org.springframework.security.core.userdetails.UserDetails 类，它已经在扩展java.io.Serializable 接口
@BigDong 没错！事实上，这不是问题！升级 spring-boot 后我遇到了这个问题...有人找到解决方案吗？
找到了！我分享给大家：问题是安全链中的过滤顺序。我通过为 redis 配置@Order(Ordered.HIGHEST_PRECEDENCE) 设置更高的优先级来解决它（我设置了最高优先级，但也许更低的优先级就足够了）。现在我的主体已正确填充。

【解决方案2】：

为了使它在我的情况下工作，我还必须确保以正确的顺序设置 Servlet 过滤器。

对我来说是：

...
<filter-name>CharacterEncodingFilter</filter-name>
...
<filter-name>springSessionRepositoryFilter</filter-name>
...
<filter-name>springSecurityFilterChain</filter-name>
...
<filter-name>csrfFilter</filter-name>
...

之后，principal 不再为空。

【讨论】：

【解决方案3】：

正如@yglodt 所说，问题在于过滤器在弹簧安全过滤器链中的顺序。

在Java Config方式中，只需给Redis配置类设置更高的优先级

@Configuration
@EnableRedisHttpSession
@Order(Ordered.HIGHEST_PRECEDENCE)
public class RedisConfig extends AbstractHttpSessionApplicationInitializer {

    @Bean
    public JedisConnectionFactory connectionFactory() {
        return new JedisConnectionFactory();
    }

}

我设置了最高优先级，但也许更低的优先级就足够了。

现在应该正确填充主体。

【讨论】：

【解决方案4】：

HttpSecurity 链的顺序很重要：

不起作用，并且将主体名称保留为空：

    .authorizeRequests()
    .antMatchers("/api/register").permitAll()
    .anyRequest().authenticated()

工作正确：

        .authorizeRequests()
        .anyRequest().authenticated()
        .antMatchers("/api/register").permitAll()
