我嘗試配置 Spring Security，但遇到一個問題。這是我的 SessionAuthenticationFilter：public class SessionAuthenticationFilter extends OncePerRequestFilter {    @Override    protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain)            throws ServletException, IOException {        HttpSession session = request.getSession();        User user = (User) session.getAttribute("user");        if (nonNull(user)) {            SimpleGrantedAuthority authority = new SimpleGrantedAuthority(user.getRole());            Authentication authentication = new UsernamePasswordAuthenticationToken(user.getName(), null, singletonList(authority));            SecurityContextHolder.getContext().setAuthentication(authentication);        }        filterChain.doFilter(request, response);    }}這是我的安全配置：@Configuration@EnableWebSecurity@EnableJdbcHttpSession@EnableGlobalMethodSecurity(prePostEnabled = true)public class SecurityConfig extends WebSecurityConfigurerAdapter {    @Bean    public SessionAuthenticationFilter sessionFilter() {        return new SessionAuthenticationFilter();    }    @Bean    public HttpSessionIdResolver httpSessionIdResolver() {        return HeaderHttpSessionIdResolver.xAuthToken();    }    @Override    protected void configure(HttpSecurity http) throws Exception {        http                .csrf().disable()                .formLogin().disable()                .cors()                .and()                .httpBasic()                .and()                .sessionManagement()                .sessionCreationPolicy(SessionCreationPolicy.STATELESS)                .and()                .addFilterBefore(sessionFilter(), SessionManagementFilter.class)                .authorizeRequests()                .antMatchers(                        "/login"    }}在 SessionAuthenticationFilter 內部 HttpSession 是正確的，但是當我嘗試獲取此會話時，我將獲取其他會話。為什么？我了解這是創建 Spring Security 的。它是如何固定的？
