与Hazelcast和Tomcat的Spring Boot

Question

如何使用Hazelcast作为带有Spring Boot和Spring Security的嵌入式Tomcat的http会话存储？我看到有一个EmbeddedServletContainerCustomizer和SpringAwareWebFilter,但我不明白如何使用它.

Answer 1

如Hazelcast的文档中所述,您需要配置Hazelcast SpringAwareWebFilter和SessionListener.您可以通过分别声明a FilterRegistrationBean和a来在Spring Boot中执行此操作ServletListenerRegistrationBean:

@Bean
public FilterRegistrationBean hazelcastFilter() {
    FilterRegistrationBean registration = new FilterRegistrationBean(new SpringAwareWebFilter());

    registration.addUrlPatterns("/*");
    registration.setDispatcherTypes(DispatcherType.REQUEST, DispatcherType.FORWARD, DispatcherType.INCLUDE);

    // Configure init parameters as appropriate:
    // registration.addInitParameter("foo", "bar");

    return registration;
}

@Bean
public ServletListenerRegistrationBean<SessionListener> hazelcastSessionListener() {
    return new ServletListenerRegistrationBean<SessionListener>(new SessionListener());
}

SpringAwareWebFilter并且SessionListener都在Hazelcast的hazelcast-wm模块中,因此您需要添加依赖于com.hazelcast:hazelcast-wm您pom.xml或build.gradle.hazelcast-wm还要求Spring Security位于类路径上.

现在,当您运行应用程序时,您应该在启动期间看到Hazelcast的日志输出,类似于以下内容:
