Why Apache Camel result on Graceful shutdown - kotlin

Question

Hello I have an app written in Kotlin and using Spring boot Framework and Apache Camel:
https://camel.apache.org/components/latest/smpp-component.html#_spring_boot_auto_configuration
So I am new in Smpp protocol I am suppuse trying to connecto to SMC simulator so I guess my
"client" should be wait for a message from SMC in this case when I run the application it
appears just stop and anymore. As it just stops I would think something is wrong.
#Bean
fun camelContextConfiguration(): CamelContextConfiguration{
return object : CamelContextConfiguration {
override fun afterApplicationStart(camelContext: CamelContext?) {
logger.info("*********************************************************************************")
//var query : Query?
//val oldRoute : List<Route> = camelContext!!.routes
camelContext!!.routes
//logger.info("Old Routes")
//logger.info(oldRoute.size.toString())
// for(route:Route in oldRoute) {
// logger.info("Route with routeId {} is deleted",route.id)
// camelContext.stopRoute(route.id)
// camelContext.removeRoute(route.id)
// }
camelContext.isUseMDCLogging=true
logger.info("ROUTES")
val routeDefinition = RouteDefinition()
routeDefinition.id="1"
routeDefinition.onException(Exception::class.java).handled(true)
.process(exceptionProcessor())
.end()
routeDefinition.from("smpp://smppclient#smscsim.melroselabs.com:2775?password=password&enquireLinkTimer=3000&transactionTimer=5000&systemId=145244&systemType='Receiver'")
routeDefinition.to("log:com.app.smppdispenser.infraestructure.smpp?showBody=true&showHeaders=true")
routeDefinition.process(messageProcessor())
camelContext.addRouteDefinition(routeDefinition)
//routeDefinition.setHeader("CamelSmppCommandId", constant("query_sm"))
//routeDefinition.setHeader("CamelSmppSequenceNumber", constant("1"))
logger.info("Route is added with routeId {} ",routeDefinition.id)
//}
logger.info("CamelConfiguration afterApplicationStart OK")
}
override fun beforeApplicationStart(camelContext: CamelContext?) {
logger.info("CamelConfiguration beforeApplicationStart")
}
}
}
This is the log>

Edit
I have added thse option: camel.springboot.main-run-controller = true then I see this new line in my log but it finish of the same way.

Answer 1

there are some options:
add a spring boot starter web which starts a web server and keep the application running
use a property as explained here: https://camel.apache.org/camel-spring-boot/3.7.x/spring-boot.html#SpringBoot-Keepingapplicationalive
