JBoss7.2-启用单例

Question

我正在从JBoss 6.4 -> JBoss 7.2迁移应用程序，尽管我在org.jboss.as.clustering.singleton中包括了jboss-deployment-structure.xml模块依赖项，并通过部署命令将其添加，但仍收到下面的错误。

使用Java 11为JBoss 7.2设置Singleton模块是否有其他方法？

错误

Caused by: org.jboss.modules.ModuleNotFoundException: org.jboss.as.clustering.singleton"

standalone.xml-单例子系统

<subsystem xmlns="urn:jboss:domain:singleton:1.0">
      <singleton-policies default="default">
           <singleton-policy name="default" cache-container="server">
                   <simple-election-policy position="-1"/>
            </singleton-policy>
       </singleton-policies>
</subsystem>

CLI命令

if (outcome != success) of ./subsystem=singleton:read-resource()
    batch
    ./subsystem=singleton:add(default=default)
    ./subsystem=singleton/singleton-policy=default:add(cache-container=server)
    ./subsystem=singleton/singleton-policy=default/election-policy=simple:add(position=-1)
    run-batch
    reload
end-if

将singleton-deployment.xml添加到我的META-INF文件夹中>

<?xml version="1.0" encoding="UTF-8"?>
<singleton-deployment policy="default" xmlns="urn:jboss:singleton-deployment:1.0"/>
