Spring boot integrationn smpp: нулевой указатель

Я пытаюсь реализовать spring -boot-integration-smpp, но получаю исключение с нулевым указателем.

интеграция-context.xml

<!--smpp integration-->
<int-smpp:outbound-gateway
        id = "smppIntegrationOutboundGateway"
        request-channel = "toSMPPChannel"
        source-address = "Indosat"
        smpp-session-ref = "smppSession"
        reply-channel = "fromSMPPChannel"/>

<int:service-activator ref = "printService" method = "print" input-channel = "fromSMPPChannel">
    <int:poller fixed-delay = "1"/>
</int:service-activator>

<int:gateway id = "smsGateway" service-interface = "com.omexit.niger.smsworker.service.SMSGateway" default-request-channel = "toSMPPChannel"/>

<!-- connect to the local broker using the default user name and password -->
<bean id = "rabbitConnectionFactory" class = "org.springframework.amqp.rabbit.connection.CachingConnectionFactory">
    <constructor-arg value = "${spring.rabbitmq.host}"/>
    <constructor-arg value = "${spring.rabbitmq.port}"/>
    <property name = "username" value = "${spring.rabbitmq.username}"/>
    <property name = "password" value = "${spring.rabbitmq.password}"/>
</bean>

<bean id = "smppSession" class = "org.springframework.integration.smpp.session.SmppSessionFactoryBean">
    <property name = "host" value = "xxxx"/>
    <property name = "port" value = "xx"/>
