This Spring Boot starter can be used by any Spring Boot application that wants to send SMS messages using SMPP. SMPP v3.4 spec

• Sending message with delivery receipt
• Sending datagram message (without delivery receipt)
• Sending silent message
• Sending flash message
• Cancel message
• Multiply SMPP connection
• SMPP connection load balancing

Add the following dependency to your project:

Maven:

<dependency>
  <groupId>com.github.mikesafonov</groupId>
  <artifactId>spring-boot-starter-smpp</artifactId>
  <version>latest</version>
</dependency>

Gradle:

dependencies {
    implementation 'com.github.mikesafonov:spring-boot-starter-smpp:latest'
}

Configure spring-boot application via properties (see Configuration section).

Use SenderManager to send SMS:

public class RoundRobinApplicationService {
    private final SenderManager senderManager;

    public void sendMessage(String from, String to, String text) {
        Message message = Message.simple(text)
                .from(from)
                .to(to)
                .build();
        senderManager.getClient().send(message);
    }
}

The following tables show the available configuration:

Configuration example for .properties file:

smpp.connections.one.credentials.host=localhost
smpp.connections.one.credentials.username=user
smpp.connections.one.credentials.password=pass
smpp.connections.one.credentials.port=1111
smpp.connections.two.credentials.host=localhost
smpp.connections.two.credentials.username=user2
smpp.connections.two.credentials.password=pass2
smpp.connections.two.credentials.port=2222

Configuration example for .yaml file:

smpp:
    default:
        maxTry: 10
        ucs2Only: true
    connections:
        one:
           credentials:
                host: localhost
                username: user
                password: pass
                port: 1111
        two:
           credentials:
                host: localhost
                username: user2
                password: pass2
                port: 2222

You can build application using following command:

./gradlew clean build -x signArchives

JDK >= 1.8

You can run unit tests using following command:

./gradlew test

You can run mutation tests using following command:

./grdlew pitest

You will be able to find pitest report in build/reports/pitest/ folder.

You can run integration tests using following command:

./grdlew testIntegration

This starter provides several abstractions:

This interface represents smpp protocol TRANSMITTER or TRANSCEIVER (see connectionType property) client. This is entry point to sending any messages. Spring-boot-starter-smpp comes with several implementations:

This is default implementation. DefaultSenderClient creates real smpp connection and performing all requests.

TestSenderClient should be used for testing purpose. TestSenderClient client may provide real smpp connection via proxy implementation of SenderClient. Every incoming request will be redirected to real SenderClient only if destination phone contains in list of allowed phone (smpp.connections.<name>.allowedPhones property). Otherwise response will be generated by SmppResultGenerator.

MockSenderClient does not perform any connection via smpp and only generate response using SmppResultGenerator.

Implementations of this interface is used by MockSenderClient and TestSenderClient clients to generate request response.

Starter by default use AlwaysSuccessSmppResultGenerator which always generate success response with random smsc message id.

You can implement own SmppResultGenerator to add custom logic.

DefaultSenderClient use implementation of TypeOfAddressParser to detect TON and NPI parameters for source and destination address of message. Starter provide DefaultTypeOfAddressParser and UnknownTypeOfAddressParser implementations.

By default starter use DefaultTypeOfAddressParser. DefaultTypeOfAddressParser supports international and alphanumeric ton parameters, otherwise return UNKNOWN ton/npi.

UnknownTypeOfAddressParser always return UNKNOWN ton/npi. This means what your SMS center must detect this parameters by himself.

This abstraction represent connection via SMPP with RECEIVER or TRANSCEIVER (see connectionType property) type. Key purpose is listening delivery receipts. By default starter use DefaultResponseClient. This class keeping smpp connection and pushing all incoming PDU to SmppSessionListener.

This class dedicated to listening all incoming PDU traffic. By default starter use ResponseSmppSessionHandler. This class find delivery receipts and push to DeliveryReportConsumer.

DeliveryReportConsumer dedicated to handle DeliveryReport on client side. Client may build custom logic on receiving delivery receipts by implementing this interface. Starter use by default NullDeliveryReportConsumer if client doesnt provide any implementation of DeliveryReportConsumer. NullDeliveryReportConsumer ignore any delivery receipts.

You can use custom SmppSessionListener by creating appropriate bean.

This is high level abstraction over sender clients.

This starter comes with one default implementation - StrategySenderManager. StrategySenderManager holds list of smsc connections and return sender client based on some rules which implemented by IndexDetectionStrategy

There are two default implementation of IndexDetectionStrategy - RandomIndexDetectionStrategy(return random sender client) and RoundRobinIndexDetectionStrategy (return sender client based on round and robbin algorithm). RoundRobinIndexDetectionStrategy strategy used by default.
