dataSource
is a bean which gets auto injected in services
when used. All beans are auto wired in grails artifacts (controllers, services etc) by default. In your case you are using a POGO and I suppose it would be inside src/groovy
.
You can inject the dataSource
bean explicitly to POGO class by making it a bean by itself
//resources.groovy
beans = {
myPogo(MyPogo){
dataSource = ref('dataSource')
}
}
//MyPogo.groovy
MyPogo {
def dataSource
....
}
This is an expensive operation. If you already are accessing applicationContext
or grailsApplication
in POGO then you need not create a bean as mentioned above.
dataSource
bean can be directly fetched from the context as:
//ctx being ApplicationContext
def dataSource = ctx.getBean('dataSource')
//or if grailsApplication is available
def dataSource = grailsApplication.mainContext.getBean('dataSource')
If you are invoking the POGO class methods from a grails artifact then use below approach than all of the above approaches. For example:
//service class
class MyService {
def dataSource //autowired
def serviceMethod(){
MyPogo pogo = new MyPogo()
pogo.dataSource = dataSource //set dataSource in POGO
}
}
