我正在尝试使用hazelcast-wm 3.0、hazelcast-spring 3.0、spring 3.2.2和servlet-api 3.0对 http 会话进行集群化。

PropertiesListener 设置 System.properties：cluster.members、cluster.member.address 等，取决于运行的机器。
如果我使用应用程序的 Spring Context 创建 hazelcast 实例，它的效果很好：
@Configuration
@ImportResource("classpath:hazelcast-context.xml")
public class HazelcastConfig {
}
效果很好！Hazelcast 实例绑定到正确的网络接口。
但问题是当我使用 WebFilter 时（以前，我删除了 HazelcastConfig 类，所以不要两次创建 Hazelcast 实例。
这些是出现在日志中的消息：

正确的 IP 应该是 11.1.0.133（${cluster.member.address} 值），Hazelcast 正在选择我 PC 的网络接口之一，但没有使用 ${cluster.member.address} 值。
如何将 WebFilter 与系统属性一起使用？
提前致谢！
