I am trying to implement spring-boot-integration-smpp, but getting null pointer exception.

integration-context.xml

<!--smpp integration-->

<int-smpp:outbound-gateway

        id="smppIntegrationOutboundGateway"

        request-channel="toSMPPChannel"

Looks like a bug in the SmppOutboundGateway: we can't start session so early from the onInit(). Please, raise an issue against https://github.com/spring-projects/spring-integration-extensions project.

Meanwhile as a workaround you can inject a reconnectingExecutor property on the SmppSessionFactoryBean:

<bean id="smppSession" class="org.springframework.integration.smpp.session.SmppSessionFactoryBean">

    <property name="host" value="xxxx"/>

    <property name="port" value="xx"/>

    <property name="systemId" value="LBS1"/>

    <property name="password" value="Bsl04n1"/>

    <property name="systemType" value="TCP"/>

    <property name="addrTon" value="INTERNATIONAL"/>

    <property name="addrNpi" value="ISDN"/>

    <property name="autoStartup" value="true"/>

    <property name="reconnectingExecutor" ref="reconnectingExecutorService"/>

</bean>
