smpp客户端_SMPP Java示例（客户端）

smpp客户端

这篇文章通过创建一个简单的SMPP客户端向移动用户发送短信来提供SMPP Java示例，使用该客户端我们可以简单地提交以将消息发送给单个移动用户，也可以一次将消息广播给多个移动用户。另外，我们将验证交货收据。出于客户端的目的，我们将使用现有的Java SMPP客户端库– jSMPP

什么是SMPP

SMPP代表短消息对等。它是一种开放的行业标准协议，旨在为短消息数据的传输提供灵活的数据通信接口。大多数时候，SMPP用于批量传送短消息，您可以一次将消息广播给数千个订户。不仅限于短消息，我们还可以携带语音邮件通知，小区广播，WAP消息（包括WAP Push消息）

SMPP操作

SMPP使用客户机/服务器操作模型。在向SMPP提交任何消息之前，我们发送一个bind命令。在此示例中，我们将发送bind_transmitter，因为我们仅对向服务器提交消息感兴趣。除了bind_transmitter以外，其他bind命令是bind_receiver，这意味着客户端将仅接收消息，bind_transceiver允许双向传输消息。

SMPP操作的完整细节不在本文讨论范围之内。如果您想详细了解操作，请访问– SMPP Wiki

使用jSMPP

要开始使用SMPP客户端，我们将使用jSMPP。要将jSMPP包含在您的项目中，请将以下maven依赖项添加到pom.xml中

pom.xml

<dependency><groupId>org.jsmpp</groupId><artifactId>jsmpp</artifactId><version>2.3.5</version>
</dependency>

SMPP多次提交示例

正如我们讨论的那样，SMPP可用于向单个或多个订户发送消息。以下是向多个移动订户发送消息的示例。第一步是使用主机名，用户名和密码向服务器发送绑定命令。我们正在initSession（）中执行此操作。完成此操作后，将创建SMPP会话，然后我们可以使用此会话发送消息。

相应的提供程序将提供不同的参数，例如ip，主机，用户名，密码。

MultipleSubmitExample.java

public class MultipleSubmitExample {private static final Logger LOGGER = LoggerFactory.getLogger(MultipleSubmitExample.class);private static final TimeFormatter TIME_FORMATTER = new AbsoluteTimeFormatter();private final String smppIp = "127.0.0.1";private int port = 8086;private final String username = "localhost";private final String password = "password";private final String address = "AX-DEV";private static final String SERVICE_TYPE = "CMT";public void broadcastMessage(String message, List numbers) {LOGGER.info("Broadcasting sms");SubmitMultiResult result = null;Address[] addresses = prepareAddress(numbers);SMPPSession session = initSession();if(session != null) {try {result = session.submitMultiple(SERVICE_TYPE, TypeOfNumber.NATIONAL, NumberingPlanIndicator.UNKNOWN, address,addresses, new ESMClass(), (byte) 0, (byte) 1, TIME_FORMATTER.format(new Date()), null,new RegisteredDelivery(SMSCDeliveryReceipt.FAILURE), ReplaceIfPresentFlag.REPLACE,new GeneralDataCoding(Alphabet.ALPHA_DEFAULT, MessageClass.CLASS1, false), (byte) 0,message.getBytes());LOGGER.info("Messages submitted, result is {}", result);Thread.sleep(1000);} catch (PDUException e) {LOGGER.error("Invalid PDU parameter", e);} catch (ResponseTimeoutException e) {LOGGER.error("Response timeout", e);} catch (InvalidResponseException e) {LOGGER.error("Receive invalid response", e);} catch (NegativeResponseException e) {LOGGER.error("Receive negative response", e);} catch (IOException e) {LOGGER.error("I/O error occured", e);} catch (Exception e) {LOGGER.error("Exception occured submitting SMPP request", e);}}else {LOGGER.error("Session creation failed with SMPP broker.");}if(result != null && result.getUnsuccessDeliveries() != null && result.getUnsuccessDeliveries().length > 0) {LOGGER.error(DeliveryReceiptState.getDescription(result.getUnsuccessDeliveries()[0].getErrorStatusCode()).description() + " - " +result.getMessageId());}else {LOGGER.info("Pushed message to broker successfully");}if(session != null) {session.unbindAndClose();}}private Address[] prepareAddress(List numbers) {Address[] addresses = new Address[numbers.size()];for(int i = 0; i< numbers.size(); i++){addresses[i] = new Address(TypeOfNumber.NATIONAL, NumberingPlanIndicator.UNKNOWN, numbers.get(i));}return addresses;}private SMPPSession initSession() {SMPPSession session = new SMPPSession();try {session.setMessageReceiverListener(new MessageReceiverListenerImpl());String systemId = session.connectAndBind(smppIp, Integer.valueOf(port), new BindParameter(BindType.BIND_TX, username, password, "cp", TypeOfNumber.UNKNOWN, NumberingPlanIndicator.UNKNOWN, null));LOGGER.info("Connected with SMPP with system id {}", systemId);} catch (IOException e) {LOGGER.error("I/O error occured", e);session = null;}return session;}public static void main(String[] args) {MultipleSubmitExample multiSubmit = new MultipleSubmitExample();multiSubmit.broadcastMessage("Test message from devglan", Arrays.asList("9513059515", "8884377251"));}
}

在创建SMPP会话时，我们已经注册了消息接收方侦听器，该侦听器将用于获取消息的传递收据。以下是示例。

MessageReceiverListenerImpl.java

public class MessageReceiverListenerImpl implements MessageReceiverListener {private static final Logger LOGGER = LoggerFactory.getLogger(MessageReceiverListenerImpl.class);private static final String DATASM_NOT_IMPLEMENTED = "data_sm not implemented";public void onAcceptDeliverSm(DeliverSm deliverSm) throws ProcessRequestException {if (MessageType.SMSC_DEL_RECEIPT.containedIn(deliverSm.getEsmClass())) {try {DeliveryReceipt delReceipt = deliverSm.getShortMessageAsDeliveryReceipt();long id = Long.parseLong(delReceipt.getId()) & 0xffffffff;String messageId = Long.toString(id, 16).toUpperCase();LOGGER.info("Receiving delivery receipt for message '{}' from {} to {}: {}",messageId, deliverSm.getSourceAddr(), deliverSm.getDestAddress(), delReceipt);} catch (InvalidDeliveryReceiptException e) {LOGGER.error("Failed getting delivery receipt", e);}}}public void onAcceptAlertNotification(AlertNotification alertNotification) {LOGGER.info("AlertNotification not implemented");}public DataSmResult onAcceptDataSm(DataSm dataSm, Session source)throws ProcessRequestException {LOGGER.info("DataSm not implemented");throw new ProcessRequestException(DATASM_NOT_IMPLEMENTED, SMPPConstant.STAT_ESME_RINVCMDID);}
}

SMPP交货收据

SMPP提供了许多标准的交货收据错误代码来标识交货收据。我们几乎没有采取任何措施来识别实际的收货信息。有关完整的详尽清单，请遵循– smpperrorcodes

DeliveryReceiptState.java

package com.devglan.smpp;public enum DeliveryReceiptState {ESME_ROK(0, "Ok - Message Acceptable"),ESME_RINVMSGLEN(1, "Invalid Message Length"),ESME_RINVCMDLEN(2, "Invalid Command Length"),ESME_RINVCMDID(3, "Invalid Command ID"),ESME_RINVBNDSTS(4, "Invalid bind status"),ESME_RALYBND(5,  "Bind attempted when already bound"),ESME_RINVPRTFLG(6, "Invalid priority flag"),ESME_RINVREGDLVFLG(7, "Invalid registered-delivery flag"),ESME_RSYSERR(8,    "SMSC system error"),ESME_RINVSRCADR(9, "Invalid source address"),ESME_RINVDSTADR(11, "Invalid destination address"),ESME_RINVMSGID(12, "Invalid message-id"),NOT_FOUND(000, "Couldn't resolve.Ask admin to add.");private int value;private String description;DeliveryReceiptState(int value, String description) {this.value = value;this.description = description;}public static DeliveryReceiptState getDescription(int value) {for (DeliveryReceiptState item : values()) {if (item.value() == value) {return item;}}return NOT_FOUND;}public int value() {return value;}public String description() {return description;}}

SMPP单一提交示例

jSMPP为单个提交提供了commitShortMessage（）。以下是实现。源代码中提供了完整的实现。

String messageId = session.submitShortMessage(SERVICE_TYPE,TypeOfNumber.NATIONAL, NumberingPlanIndicator.UNKNOWN, address,TypeOfNumber.NATIONAL, NumberingPlanIndicator.UNKNOWN, number,new ESMClass(), (byte)0, (byte)1,  TIME_FORMATTER.format(new Date()), null,new RegisteredDelivery(SMSCDeliveryReceipt.FAILURE), (byte)0, new GeneralDataCoding(Alphabet.ALPHA_DEFAULT, MessageClass.CLASS1, false), (byte)0,message.getBytes());

结论

这是Java中SMPP客户端实现的简单示例。在下一篇文章中，我们将讨论其模拟器。
