Java 在正常功能上实现调度程序错误

Question

目前，我有我的java应用程序，我从主函数中调用了该函数，然后所有的工作都完成了。下面是我的代码片段。所以我需要及时运行函数的调用并阅读有关调度程序的信息。所以我尝试在我的主函数中实现它并收到错误:此处不允许“void”类型final ScheduledFuture<?> timeHandle = scheduler.scheduleAtFixedRate(ws1TI(), 0, 10);这个问题有什么解决办法吗“？

public class ws1TI
{
public static void ws1TI()
      {
            try
            {
             SOAPConnectionFactory soapConnectionFactory = SOAPConnectionFactory.newInstance();
             SOAPConnection soapConnection = soapConnectionFactory.createConnection();
             String url = "http://*********.asmx?WSDL";
             SOAPMessage soapResponse = soapConnection.call(createSOAPRequest(), url);
             printSOAPResponse(soapResponse);
             updateAcknoledgement();
            }
            catch (Exception e)
            {
                  e.printStackTrace();
                  System.err.println(e.toString());
            }
      }
      public static     void main(String[] args)
      {
        ScheduledExecutorService scheduler =Executors.newSingleThreadScheduledExecutor();   
        final ScheduledFuture<?> timeHandle = scheduler.scheduleAtFixedRate(ws1TI(), 0, 10); 

      }    
}

Answer 1

scheduleAtFixedRate 应收到 Runnable ，不是空值。例如，您可以将 ws1TI 函数转换为 Runnable，如下所示:

public class ws1TI {
    public static class WS1TI implements Runnable {
        @Override
        public void run() {
            try {
                 SOAPConnectionFactory soapConnectionFactory = SOAPConnectionFactory.newInstance();
                 SOAPConnection soapConnection = soapConnectionFactory.createConnection();
                 String url = "http://*********.asmx?WSDL";
                 SOAPMessage soapResponse = soapConnection.call(createSOAPRequest(), url);
                 printSOAPResponse(soapResponse);
                 updateAcknoledgement();
            }
            catch (Exception e) {
                 e.printStackTrace();
                 System.err.println(e.toString());
            }
        }
    }

    public static void main(String[] args) {
        ScheduledExecutorService scheduler =
            Executors.newSingleThreadScheduledExecutor();   
        final ScheduledFuture<?> timeHandle = 
            scheduler.scheduleAtFixedRate(new WS1TI(), 0L, 10L, TimeUnits.MINUTE); 
    }
}
