【中文标题】为啥 Spring Security getAuthentication() 在服务器上返回 null【英文标题】：Why Spring Security getAuthentication() returns null on server为什么 Spring Security getAuthentication() 在服务器上返回 null 【发布时间】：2021-12-23 19:29:33 【问题描述】：

我有一个 Web 应用程序并使用 Spring Security 进行身份验证。所有页面都需要认证，但登录页面不需要认证。在我的情况下，我在本地环境登录后成功访问了其他需要身份验证的页面。但是我在服务器环境中失败了。因为 getAuthentication() 返回 null。我不知道为什么 getAuthentication() 在服务器环境中返回 null。

登录后移动到 /foo 时（本地日志）

我的源代码

我只有 Config 和 Spring Security

@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter 


    @Override
    public void configure(WebSecurity web) throws Exception 
      web
        .ignoring()
        .antMatchers("/images/**", "/js/**", "/css/**");
    

    @Override
    protected void configure(HttpSecurity http) throws Exception 
        http
            .authorizeRequests()
              .mvcMatchers(loginPage).permitAll()
              .anyRequest().authenticated()
             .and()
              .formLogin()
               .loginPage(loginPage)
               .loginProcessingUrl(loginSuccessUrl)
               .successHandler(new AuthenticationSuccessHandler() 
                    @Override
                    public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response,
                            Authentication authentication) throws IOException, ServletException 
                        //add Session
                        request.getSession().setMaxInactiveInterval(180000);
                        //move page
                        response.sendRedirect(fooPage);
                    
                );

登录实现UserDetailsService

@Service
public class Login implements UserDetailsService
    
    
    private final LoginInfoRepository loginRepo;
    
    @Autowired
    public Login(LoginInfoRepository loginRepo) 
        this.loginRepo = loginRepo;
    

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException 
        LoginInfoEntity entity = loginRepo.findById(username)
                .orElseThrow(() -> new UsernameNotFoundException("not exist user"));
        
        UserDetails userDetails = new LoginUser(entity);
        
        return userDetails;

loginUser 用于会话信息

public class LoginUser extends User 

    @SuppressWarnings("unchecked")
    public LoginUser(LoginInfoEntity loginInfo) 
        super(loginInfo.getUserId(), loginInfo.getPassword(), 
                loginInfo.isAvailable(), true, true, true, Collections.EMPTY_SET);

[2021-11-11 06:17:15:126766][foo] 调试 org.springframework.security.web.authentication.AnonymousAuthenticationFilter - 将 SecurityContextHolder 设置为匿名 SecurityContext

这是理解问题的关键。当您进行重定向时，您正在重定向用户，是的。但是，他的会话信息 (cookie) 或其他一些东西不是这个重定向请求的一部分。

因此，从/foo 端点的角度来看，它没有获得任何凭据信息，并将请求视为匿名。

如果你能摆脱这段代码......

successHandler(.. do redirect ...)

不要像这样进行重定向，而是像this那样做，它可能会解决问题。

通过defaultSuccessUrl重定向

 http.formLogin().defaultSuccessUrl("/success.html", true);

这能解决您的问题吗？在 cmets 中告诉我。

您还可以启用 HTTP 请求跟踪，并准确查看带有哪些标头和有效负载的请求将到达 /foo 端点，这将更容易诊断问题。

您是否使用 cookie 或 JWT 进行身份验证？在 cmets 中告诉我。

【讨论】：

感谢您的回答。我没有使用 cookie 或 JWT 进行身份验证。代码就是全部。 defaultSuccessUrl 谢谢。我很担心因为我尝试在登录后通过直接输入xxxx/foo 移动页面，但我失败了。无论如何我会尝试你的答案。 @Carmel 告诉我它是否有效我试过了。谢谢它运作良好。但我需要「request.getSession().setMaxInactiveInterval(180000)」，我应该更新 180000 或任何间隔。因为我应该使用 successHandler 而不是 defaultSuccessUrl。你可以使用这个http对象以另一种方式设置，不需要依赖servlet API【参考方案2】：

我解决了这个问题。谢谢亚瑟·克莱佐维奇。 原因是 contextpath 没有重定向。我认为本地环境等于服务器环境。但服务器环境有 contextpath 因为我没有为 contextpath 设置。它会导致 url 涉及 contextpath。

例如）

成功在本地登录后获取会话 - http://99.99.99/foo

登录服务器后获取会话失败 - http://99.99.99/foo(question's url)

成功登录服务器后获取会话 -http://99.99.99/contextpath/foo

有几种方法可以删除 contextpath 的 url。我选择了最简单的方法更改战争名称文件
