java@Schedule导致重复ServiceException
我试图在我的JAX-WS项目中实现一个简单的方法，目前，它每秒都会打印到控制台。我找到了this简单的指南，并尝试将其应用到我当前的工作项目中
我的TimerService.java看起来像这样：
package brass.ducks.controller;
import javax.ejb.EJB;
import javax.ejb.Schedule;
import javax.ejb.Singleton;
@Singleton
public class TimerService {
@EJB
HelloService helloService;
@Schedule(second="*/1", minute="*",hour="*", persistent=false)
public void doWork(){
System.out.println("timer: " + helloService.sayHello());
}
}
我的HelloService.java看起来像这样：
package brass.ducks.controller;
import javax.ejb.Stateless;
@Stateless
public class HelloService {
public String sayHello(){
return "Hello from control: " + System.currentTimeMillis();
}
}
我注意到教程提到了一些关于如何部署的内容？在我本地的WildFly服务器上部署项目就可以解决这个问题，还是需要其他东西
这也是我的stacktrace：

# 1 楼答案
尝试使用以下步骤：
以下是我为解决这个问题而采取的步骤
一,。停止服务器
二,。转到部署路径
三,。手动删除部署文件夹中的现有项目
四,。重新启动服务器
五,。再次部署应用程序
因为从错误来看，服务器上似乎已经部署了“.BrassDucks.BrassDucks.TimerService”
