Using resources.groovy for Spring DSL with Environment switch

I was having issues trying to get my Spring DSL to operate in ./grails-app/spring/resources.groovy. I have been able to use XML formatting in resources.xml, but I wanted to leverage groovy as well as be able to replace certain beans based on environment such as using Mock objects during test.

There are several issues I had in my conversion.

First: I needed to use equal signs (=)  instead of colon (:) for assignments. I see the colon notation everywhere, and even in some Spring examples, but it did not work for me.

So this: serviceName : “RoutingLookupService”

changed into: serviceName = “RoutingLookupService”

Second: I had another issue trying to get my external configuration from ${userHome}/.grails/${appName}-config.groovy into this bean declaration.

So this: wsdlDocumentUrl = “${routingLookupService.wsdlDocumentUrl}

changed into: wsdlDocumentUrl = ConfigurationHolder.config.routingLookupService.wsdlDocumentUrl

In the end, I has ended up with the following declaration for resources.groovy

import org.codehaus.groovy.grails.commons.ConfigurationHolder

beans = {
    println "~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~"

    switch (grails.util.GrailsUtil.environment) {

        case "production":
            println "Creating production Spring beans"
            routingLookupService(org.springframework.remoting.jaxws.JaxWsPortProxyFactoryBean) {
                serviceInterface = "com.comcast.ivr.das.services.RoutingLookupServicePortType"
                wsdlDocumentUrl = ConfigurationHolder.config.routingLookupService.wsdlDocumentUrl
                namespaceUri = "http://services.das.ivr.comcast.com"
                serviceName = "RoutingLookupService"
                endpointAddress = ConfigurationHolder.config.routingLookupService.endpointAddress
                maintainSession = "true"
            }
            break

        case "test":
            println "Creating test Spring beans"
            routingLookupService(org.easymock.EasyMock,
                    "com.comcast.ivr.das.services.RoutingLookupServicePortType") {bean ->
                bean.factoryMethod = "createMock"
            }
            break

        case "development":
            println "Creating development Spring beans"
            routingLookupService(org.springframework.remoting.jaxws.JaxWsPortProxyFactoryBean) {
                serviceInterface = "com.comcast.ivr.das.services.RoutingLookupServicePortType"
                wsdlDocumentUrl = ConfigurationHolder.config.routingLookupService.wsdlDocumentUrl
                namespaceUri = "http://services.das.ivr.comcast.com"
                serviceName = "RoutingLookupService"
                endpointAddress = ConfigurationHolder.config.routingLookupService.endpointAddress
                maintainSession = "true"
            }

            break
    } // switch

    routingLookupServiceClient(com.comcast.ivr.das.domain.routinglookup.xsd.RoutingLookupServiceClient)
    println "~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~"

} // End beans.
