5.7. 使用外部 JGroups 堆栈

引用在 infinispan.xml 文件中定义自定义 JGroups 堆栈的外部文件。

流程

将自定义 JGroups 堆栈文件放在应用类路径上。
或者，您可以在声明外部堆栈文件时指定绝对路径。

使用 stack-file 元素引用外部堆栈文件。

<infinispan>
  <jgroups>
     <!-- Creates a "prod-tcp" stack that references an external file. -->
     <stack-file name="prod-tcp" path="prod-jgroups-tcp.xml"/>
  </jgroups>
  <cache-container default-cache="replicatedCache">
    <!-- Use the "prod-tcp" stack for cluster transport. -->
    <transport stack="prod-tcp" />
    <replicated-cache name="replicatedCache"/>
  </cache-container>
  <!-- Cache configuration goes here. -->
</infinispan>

<infinispan>
  <jgroups>
     <!-- Creates a "prod-tcp" stack that references an external file. -->
     <stack-file name="prod-tcp" path="prod-jgroups-tcp.xml"/>
  </jgroups>
  <cache-container default-cache="replicatedCache">
    <!-- Use the "prod-tcp" stack for cluster transport. -->
    <transport stack="prod-tcp" />
    <replicated-cache name="replicatedCache"/>
  </cache-container>
  <!-- Cache configuration goes here. -->
</infinispan>

您还可以使用 TransportConfigurationBuilder 类中的 addProperty （） 方法来指定自定义 JGroups 堆栈文件，如下所示：

GlobalConfiguration globalConfig = new GlobalConfigurationBuilder().transport()
        .defaultTransport()
        .clusterName("prod-cluster")
        //Uses a custom JGroups stack for cluster transport.
        .addProperty("configurationFile", "my-jgroups-udp.xml")
        .build();

GlobalConfiguration globalConfig = new GlobalConfigurationBuilder().transport()
        .defaultTransport()
        .clusterName("prod-cluster")
        //Uses a custom JGroups stack for cluster transport.
        .addProperty("configurationFile", "my-jgroups-udp.xml")
        .build();

在本例中，my-jgroups-udp.xml 使用自定义属性引用 UDP 堆栈，如下所示：
