SMSLib。Service.getInstance().stopService()不起作用

Question

我使用SMSlib库从USB3G调制解调器中兴通讯MF180发送短信。我尝试使用SendMessage.java类来测试我的调制解调器，所以我复制了短信发送代码-所以在理论上我希望收到2条短信。

OutboundNotification outboundNotification = new OutboundNotification();
    SerialModemGateway gateway = new SerialModemGateway("modem.com1", "COM6", 115200, "ZTE", "MF180");        
    gateway.setInbound(true);
    gateway.setOutbound(true);
    gateway.setSimPin("");
    gateway.setSmscNumber("+79037011111");
    Service.getInstance().setOutboundMessageNotification(outboundNotification);
    Service.getInstance().addGateway(gateway);
    Service.getInstance().startService();
    OutboundMessage msg = new OutboundMessage("79213533296", "Hello world!");
    Service.getInstance().sendMessage(msg);
    Service.getInstance().removeGateway(gateway);
    Service.getInstance().stopService();

新的outboundNotification2 = OutboundNotification OutboundNotification()；

    SerialModemGateway gateway2 = new SerialModemGateway("modem.com1", "COM6", 115200, "ZTE", "MF180");
    gateway2.setInbound(true);
    gateway2.setOutbound(true);
    gateway2.setSimPin("");
    gateway2.setSmscNumber("+79037011111");
    Service.getInstance().setOutboundMessageNotification(outboundNotification2);
    Service.getInstance().addGateway(gateway2);
    Service.getInstance().startService();
    OutboundMessage msg2 = new OutboundMessage("79213533296", "Оповещение о событии ");
    Service.getInstance().sendMessage(msg2);
    Service.getInstance().stopService();

我收到了第一条短信，然后就出现了异常：

org.smslib.GatewayException:通信库异常: java.lang.RuntimeException: gnu.io.PortInUseException: org.smslib看起来像Service.getInstance().stopService()方法不起作用。但我不知道该怎么办。

您正在尝试创建到同一COM端口的新SerialModemGateway，但这是不可行的-只有一个进程/服务可以同时打开com端口。

通过执行gateway.stopGateway()，确保在创建另一个之前停止第一个命令

虽然您不需要每次都设置和拆除SerialModemGateway并停止/启动服务，但只需创建一条新消息并使用已打开的现有网关和服务发送它即可。
