Inject a simple map into a Grails controller - grails

Question

I'm trying to inject a Map into a Grails controller. I want to inject the same map into many controllers so would like to define it in resources.groovy.
I've looked on the web but can't find an example of creating a simple map.
In Spring MVC I've used something like this:
<util:map id="diplomaPermissions">
<entry>
<key>1</key>
<value>Diploma_AQA_Building_And_Construction</value>
</entry>
<entry>
<key>1</key>
<value>Diploma_Edexcel_Building_And_Construction</value>
</entry>
</util:map>
With this in my xml header:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:util="http://www.springframework.org/schema/util"
xmlns:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://www.springframework.org/schema/util
http://www.springframework.org/schema/util/spring-util-2.5.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-2.5.xsd">
But this doesn't seem to work in grails if I use the spring xml files.
Any tips appreciated.

Answer 1

after further investigation, you can create the map in "resources.groovy"
beans = {
diplomaPermissions(org.springframework.beans.factory.config.MapFactoryBean) {
sourceMap = [
1:"Diploma_AQA_Building_And_Construction",
2:"Diploma_Edexcel_Building_And_Construction"
]
}
}

Answer 2

I think it might be related to the version of spring you are expecting; when using the old style for creating map, everything works fine.
try this in your resources.xml in the spring configuration directory
<bean id="testMap"
class="org.springframework.beans.factory.config.MapFactoryBean">
<property name="sourceMap">
<map>
<entry key="key1" value="value1"/>
<entry key="key2" value="value2"/>
</map>
</property>
</bean>
and this on your controller
class DisplayMapController {
def testMap
def index = {
render (contentType: "text/plain") {
div(id:"myDiv") { p "$testMap" }
}
}
}
