WildFly 11.0配置JGroups TCP单播失败，仍用默认UDP配置求助

我使用WildFly 11.0，参考Red Hat文档配置JGroups TCP Socket绑定，因节点处于不同子网（跨防火墙），希望用UNICAST替代多播，但日志始终提示：

[org.infinispan.remoting.transport.jgroups.JGroupsTransport] (ServerService Thread Pool -- 76) ISPN000088: Unable to use any JGroups configuration mechanisms provided in properties {}. Using default JGroups configuration!

无法使用自定义配置而采用默认JGroups配置，且Wireshark捕获到UDP流量。已尝试文档中所有步骤仍未解决，相关配置如下：

问题排查与修复方案 #

• 补全Keycloak缓存容器的Transport配置：你的keycloak缓存容器未指定<transport>，导致Infinispan默认使用UDP栈。需添加绑定到ee通道的配置：

  <cache-container name="keycloak" jndi-name="infinispan/Keycloak">
      <transport channel="ee" lock-timeout="60000"/>
      <!-- 原有local-cache配置保留 -->
  </cache-container>
  

• 优化JGroups GMS协议配置：在pbcast.GMS中添加超时属性，避免节点等待多播：

  <protocol type="pbcast.GMS">
      <property name="join_timeout">5000</property>
      <property name="print_local_addr">true</property>
  </protocol>
  

• 确认Socket绑定完整性：检查Socket绑定组是否包含TCP相关端口：

  <socket-binding-group name="standard-sockets" default-interface="public">
      <!-- 其他绑定项 -->
      <socket-binding name="jgroups-tcp" port="7600"/>
      <socket-binding name="jgroups-tcp-fd" port="57600"/>
  </socket-binding-group>
  

• 验证跨子网网络连通性：确保两个节点的7600、57600端口双向可通，防火墙未拦截TCP流量。
• 检查启动参数：确认启动WildFly时未通过-Djgroups.config系统属性指定其他配置文件，覆盖XML中的自定义设置。
