Question

我们正在尝试在Openshift内部的Wildfly 11上运行的两个infinispan节点上安装一个复制缓存。当我们在一个节点上写一个对象时，它不会显示在另一个节点上进行读取。

在启动时，节点在群集中连接，并且可以在日志中看到彼此：

22:59:52,513 INFO  [org.infinispan.remoting.transport.jgroups.JGroupsTransport] (thread-2) ISPN000094: Received new cluster view for channel mychannel: [port-12-z73rp|13] (2) [port-12-z73rp, port-12-q10wf]

缓存配置。我们尝试过交易模式，包括NONE，FULL_XA和BATCH：

<cache-container name="mycache" default-cache="MyDefault_Cache" jndi-name="java:jboss/infinispan/mycache" module="org.wildfly.clustering.server">
            <transport lock-timeout="60000"/>

            <replicated-cache name="MyCache_CategoryManager" mode="SYNC" jndi-name="java:jboss/infinispan/mycache/MyCache_CategoryManager">
              <locking
                  isolation="READ_COMMITTED"/>
              <transaction
                  locking="OPTIMISTIC"
                  mode="NONE"
                  stop-timeout="30000"/>
            </replicated-cache>
          </cache-container>
    </subsystem>

在代码中，缓存通过spring连接：

    public Map<String, Object> getCustomCache() {
    System.out.println("CACHE -> " + this.customCache.getClass());
    return customCache;
}

public void setCustomCache(Map<String, Object> customCache) {
    this.customCache = customCache;
}

@Resource(lookup = "java:jboss/infinispan/mycache/MyCache_CategoryManager")
private Map<String, Object> customCache;

Jgroups配置：

 <subsystem xmlns="urn:jboss:domain:jgroups:5.0">
        <channels default="ee">
            <channel name="ee" stack="udp" cluster="mycluster"/>
        </channels>
        <stacks>
            <stack name="udp">

数据进入数据库，如果我们在第二个节点上重建缓存，它将包含更新的信息。

鉴于节点连接，我们如何解决读取复制未发生的事实？我们尝试了复制和分布式缓存配置。

最后，配置文件中缺少一个关键配置元素。缺少密钥的元素是来自web.xml文件的资源env ref：

<resource-env-ref>
    <resource-env-ref-name>myCache</resource-env-ref-name>
    <resource-env-ref-type>org.infinispan.Cache</resource-env-ref-type>
    <lookup-name>java:jboss/infinispan/cache/myCache/myCacheManger</lookup-name>
  </resource-env-ref>

来自standalone.xml

<replicated-cache name="myCache" statistics-enabled="false" mode="SYNC"/>

Infinispan复制缓存不复制对象以进行读取
