Dead Letter Arriving When Spray-Servlet Loads

Question

I'm working with spray-servlet (using Tomcat 8 as the servlet container) and spray-routing.

Whenever I deploy my WAR, my serviceActor receives a message. This message goes to a specific path and it's always the same path and always once. The sender is the system's dead letters actor.

I am not sure where this message is coming from. Would appreciate any help debugging this issue.

Answer 1

As is mostly the case, the issue was user error.

My routes were defined like this:

... {
    doStuff()
    complete(OK)
}

Causing the loading phase of spray-routing to execute the code before stopping at complete.

I changed my code to look like this:

... {
    complete {
        doStuff()
        OK
    }
}

And everything's working as it should.
