Wildfly 10.1.0 Singleton不起作用

我在域中配置了两个Wildfly服务器，并且我需要制作一个与HA一起运行的单例。我只需要它在一台服务器上运行，如果该服务器出现故障，它应该在从服务器上启动。我正在使用defult配置，并且只在WAR中创建了“/META-INF/singleton-deployment.xml”。当我部署WAR时，它会在两台服务器上启动！不仅在一个。什么不见了？我是否需要在domain.xml中编辑某些内容？Wildfly 10.1.0 Singleton不起作用

我的单只写入一个文本日志文件和控制台，只是为了测试：

import java.net.InetAddress; 
import java.net.UnknownHostException; 
import javax.ejb.ConcurrencyManagement; 
import javax.ejb.ConcurrencyManagementType; 
import javax.ejb.Schedule; 
import javax.ejb.Singleton; 
import org.apache.logging.log4j.Level; 
import org.apache.logging.log4j.LogManager; 
import org.apache.logging.log4j.Logger; 

@ConcurrencyManagement(ConcurrencyManagementType.CONTAINER) 
@Singleton 
public class TesteAPP { 

    final Logger logger = LogManager.getLogger(TesteAPP.class); 

    @Schedule(second = "*/1", minute = "*", hour = "*", persistent = false) 
public void executaTarefa() { 
    try { 
     logger.log(Level.INFO, "Tarefa executada com sucesso! Nome da   máquina: {} Endereço da máquina: {}", 
       InetAddress.getLocalHost().getHostName(), 
       InetAddress.getLocalHost().getHostAddress()); 
     System.out.println(String.format("Tarefa executada com sucesso! Nome da máquina: %s Endereço da máquina: %s", 
       InetAddress.getLocalHost().getHostName(), 
       InetAddress.getLocalHost().getHostAddress())); 
    } catch (UnknownHostException e) { 
     logger.log(Level.ALL, "Tarefa executada com sucesso!"); 
     System.out.println(String.format("Tarefa executada com sucesso!")); 
    } 
} 


}
