如何使用vaadin4spring运行hazelcast会话复制？

我正在编写一个简单的演示应用程序，使用基于共享安全示例的hazelcast会话复制 这里提到过

问题是，如果我启动应用程序，它会停留在登录站点上，出现“通信错误”。 在启用vaadin debug的情况下，它会显示“响应未包含服务器id。请验证服务器是否为最新的，以及响应数据是否在传输中未被修改。”

在IDE中，不显示堆栈跟踪

我在这里也尝试了这个工作示例，但它没有给我一个如何将hazelcast与vaadin4spring集成的提示

以下是我的配置：

    public void configure(AuthenticationManagerBuilder auth) throws Exception {
        User.UserBuilder users = User.withDefaultPasswordEncoder();
        auth.inMemoryAuthentication().withUser("user").password("{noop}user").roles("USER")
                .and()
                .withUser("admin").password("{noop}admin").roles("ADMIN");
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.csrf().disable(); // Use Vaadin's built-in CSRF protection instead
        http.authorizeRequests().antMatchers("/login/**").anonymous()
                .antMatchers("/vaadinServlet/UIDL/**").permitAll()
                .antMatchers("/vaadinServlet/HEARTBEAT/**").permitAll().anyRequest().authenticated();
        http.httpBasic().disable();
        http.formLogin().disable();
        // Remember to add the VaadinSessionClosingLogoutHandler
        http.logout().addLogoutHandler(new VaadinSessionClosingLogoutHandler()).logoutUrl("/logout")
                .logoutSuccessUrl("/login?logout").permitAll();
        http.exceptionHandling().authenticationEntryPoint(new LoginUrlAuthenticationEntryPoint("/login"));
        // Instruct Spring Security to use the same RememberMeServices as Vaadin4Spring. Also remember the key.
        //http.rememberMe().rememberMeServices(rememberMeServices()).key("myAppKey");
        // Instruct Spring Security to use the same authentication strategy as Vaadin4Spring
        http.sessionManagement().sessionAuthenticationStrategy(sessionAuthenticationStrategy());
    }

    @Override
    public void configure(WebSecurity web) throws Exception {
        web.ignoring().antMatchers("/VAADIN/**");
    }

    /**
     * The {@link AuthenticationManager} must be available as a Spring bean for Vaadin4Spring.
     */
    @Override
    @Bean
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }

    /**
     * The {@link SessionAuthenticationStrategy} must be available as a Spring bean for Vaadin4Spring.
     */
    @Bean
    public SessionAuthenticationStrategy sessionAuthenticationStrategy() {
        return new SessionFixationProtectionStrategy();
    }

    @Bean(name = VaadinSharedSecurityConfiguration.VAADIN_AUTHENTICATION_SUCCESS_HANDLER_BEAN)
    VaadinAuthenticationSuccessHandler vaadinAuthenticationSuccessHandler(HttpService httpService,
                                                                          VaadinRedirectStrategy vaadinRedirectStrategy) {
        return new VaadinUrlAuthenticationSuccessHandler(httpService, vaadinRedirectStrategy, "/");
    }

    @Bean
    public HazelcastInstance hazelcastInstance() {
        MapAttributeConfig attributeConfig = new MapAttributeConfig()
                .setName(HazelcastSessionRepository.PRINCIPAL_NAME_ATTRIBUTE)
                .setExtractor(PrincipalNameExtractor.class.getName());

        Config config = new Config();
        config.setProperty("hazelcast.max.no.heartbeat.seconds", "60")
                .getMapConfig("spring:session:sessions")
                .addMapAttributeConfig(attributeConfig)
                .addMapIndexConfig(new MapIndexConfig(HazelcastSessionRepository.PRINCIPAL_NAME_ATTRIBUTE, false));
        config.getGroupConfig().setName("admin");

        return Hazelcast.newHazelcastInstance(config);
    }
