In my grails application I want to read some values from properties file and set it to Grails Domain class static property at startup.
Example
Class A{
static myValues="1,2";
}
class B{
static myValues="2,3";
}
In the above example I have directly given the inputs..Instead of that I want to read it from one config.properties file which will have the following
A=1,2
B=2,3
Is it possible to do that in grails.Help me please.
If you put config.properties in grails-app/conf then it'll be in the classpath and this code in grails-app/conf/BootStrap.groovy will load the properties and set the values:
class BootStrap {
def init = { servletContext ->
def props = new Properties()
def cl = Thread.currentThread().contextClassLoader
props.load cl.getResourceAsStream('config.properties')
props.each { key, value ->
def clazz = Class.forName(key, true, cl)
clazz.myValues = value
}
}
}
Obviously you'll need to check that the properties file is available, that the classes, exist, etc.
