Configuration

spray supports a number of configuration parameters that you can use to tweak sprays behavior. These config setting reside next to the akka section in your akka.conf file, in a section called spray. The Template Project comes with a very basic configuration that you can use as the basis for own.

Currently spray supports the following config settings:

• "root-actor-id", a string containing the id of the RootService actor. You should rarely need to change this. The default is "spray-root-service"
• "timeout", an integer value representing the number of milliseconds in which a request has to be responded before triggering an async timeout error response. The default is 1000.
• "set-connection-close-header", a boolean value signifying whether spray should add a Connection: close header to all responses not already having a Connection header. The default is true.
• "set-date-header", a boolean value signifying whether spray should add a proper Date header to all responses. The default is false since most of the time the web server / servlet container you deploy you spray app in already takes care of setting the Date header.
• "root-path", an optional string that, if set, is expected as a prefix of all requests URI paths received by the application and automatically removed before route processing. Useful for example in servlet containers where the spray application is deployed under a certain base URL. The default is "not set".
• "compact-json-printing", a boolean value signifying whether spray should use the CompactPrinter rather than the PrettyPrinter when using SprayJsonMarshalling (also see the Marshalling and Unmarshalling chapter). The default is false.

Additionally the spray config section may contain a sub section called users which contains username / password combinations for the FromConfigUserPassAuthenticator as discussed in the Authentication/Authorization chapter.

Example:

spray {
    timeout = 1000
    users {
        alice = "banana"
        bob = "coconut"
    }
}
