Cache plugin not caching - caching

Question

Could some wise guru give me a hand to get the Cache Plugin to work? I have been given this project that uses:
Grails 3.3.0
gradle 3.0
GORM 6.1.6.Release
Cache Plugin 4.0.0
I'm following https://grails-plugins.github.io/grails-cache/snapshot/guide/index.html#usage to enable Caching though the app can be started without error, the method that is annotated by #Cacheable doesn't seem to be caching. This is what my myWebApp**build.gradle** looks like:
:
compile group: 'org.grails.plugins', name: 'cache', version: '4.0.0'
compile group: 'org.grails.plugins', name: 'async'
:
This is my grails-app/conf/application.yml:
---
grails:
cache:
caches:
name: 'mycache'
---
This is how I enable cache in grails-app/conf/application.groovy:
:
grails.cache.enabled = true
grails.cache.clearAtStartup = true
:
This is my myWebApp/Application.groovy:
package myWebApp
:
class Application extends GrailsAutoConfiguration {
static void main(String[] args) {
GrailsApp.run(Application, args)
}
}
This is the method in a controller with #Cachable (grails-app/controllers/data/mycontroller.groovy):
package data
:
import org.springframework.cache.annotation.Cacheable
:
#Transactinal
class MyController {
:
#Cacheable(value='mycache')
def getSomeId() {
return anId
}
:
}
In the same controller, I am calling this method for quick test:
:
def index() {
def id = getSomeId()
:
}
:
The problem is getSomeId() didn't seem to be cached. Everytime getSomeId() was called, the body was executed in full length (I set a break point to verify). I just want to use a quick and simple cache mechanism for simple things like this.
What did I do wrong?
Thanks for all you folks, the cache finally works in my project. HOWEVER, the import for annotation must come from the plugin: grails.plugin.cache.Cacheable works, but org.springframework.annotation.Cacheable doesn't.
