java - 通过 SMPP 发送多条短信

Question

我会直接回答我的问题。

1. 我正在使用 Logica smpp，我想向多个号码发送短信。下面的代码给出异常。

   public void submitMulti() {
   String serviceType = "";        
   byte replaceIfPresentFlag = 0;
   String scheduleDeliveryTime = null;
   String validityPeriod = null;
   byte esmClass = 0;
   //######################
   //byte protocolId = 0;
   //byte dataCoding = 0;
   byte protocolId = 0; //0x00; commented is for flash
   byte dataCoding = (byte) 0x08; //0x18
   byte smsClass = 0x00;
   //######################
   byte ton = 1;
   byte npi = 1;
   byte priorityFlag = 0;
   byte registeredDelivery = 0;   //TODO registered delivery
   byte smDefaultMsgId =  (byte) 12; //0;
   try {
       SubmitMultiSM request = new SubmitMultiSM();
       SubmitMultiSMResp response;
   
       // input values and set some :-)
       String sourceAddress = "123456789012";
       int numberOfDestination = 10;
       for (int i = 0; i < numberOfDestination; i++) {
           request.addDestAddress(new DestinationAddress(new Address(ton,npi,"923458503302")));
       }
   
       // set other values
       request.setServiceType(serviceType);
       request.setSourceAddr(sourceAddress);
       request.setReplaceIfPresentFlag(replaceIfPresentFlag);
       request.setShortMessage("Hy");
       request.setScheduleDeliveryTime(scheduleDeliveryTime);
       request.setValidityPeriod(validityPeriod);
       request.setEsmClass(esmClass);
       request.setProtocolId(protocolId);
       request.setPriorityFlag(priorityFlag);
       request.setRegisteredDelivery(registeredDelivery);
       request.setDataCoding(dataCoding);
       request.setSmDefaultMsgId(smDefaultMsgId);
       String ipAddress = Bundle.getInstance().getValue(Bundle.Application_Contants.IP_ADDRESS.toString());
       int port = Integer.valueOf(Bundle.getInstance().getValue(Bundle.Application_Contants.PORT.toString()));
       long receiveTimeOut = Long.valueOf(Bundle.getInstance().getValue(Bundle.Application_Contants.RECEIVE_TIMEOUT.toString()));
   
       TCPIPConnection connection = new TCPIPConnection(ipAddress,port);
       connection.setReceiveTimeout(receiveTimeOut);
       customSession = new Session(connection);
   
   
       // send the request
       System.out.println("Submit Multi request " + request.debugString());
       if (!asynchronous) {
           customSession.submitMulti(request);
       } else {
           response = customSession.submitMulti(request);
           System.out.println("Submit Multi response " + response.debugString());
           messageId = response.getMessageId();
       }
   
   } catch (Exception e) {
       log.error(e,e);
       System.out.println("Submit Multi operation failed. " + e.getMessage());
   } finally {
   }
   

   }

例外是：

java.lang.NullPointerException
at org.smpp.Session.send(Session.java:1100)
at org.smpp.Session.send(Session.java:1173)
at org.smpp.Session.submitMulti(Session.java:727)
at com.noetic.topUpBooster.smpp.JarConnection.submitMulti(JarConnection.java:413)
at com.noetic.sdp.alerts.JarCheck.run(JarCheck.java:34)
Submit Multi operation failed. null

有人知道吗？

假设您的代码充当 ESME，则必须在发送任何 SubmitSM、SubmitMultiSM 或 DataSM 之前发送绑定请求（通过 BindTransmitter 或 BindTransciever）。
