Purpose
Enables the Hibernate second-level cache for the domain class.
Examples
Description
Usage: cache(boolean/string/map)
Arguments:
-
usage- The cache usage. Can beread-only,read-write,nonstrict-read-writeortransactional -
include(optional) - Whether to include non-lazy associations. Can beallornon-lazy
You enable caching per domain class, for example:
static mapping = {
cache true
}This will configure the domain class to use a 'read-write' cache, but you can configure whatever cache policy is appropriate (and supported by the cache implementation):
static mapping = {
cache 'transactional'
}or
static mapping = {
cache usage: 'read-only', include: 'non-lazy'
}You can also configure the cache policy on a per-association basis:
class Author {
static hasMany = [books: Book]
static mapping = {
books cache: true // or 'read-write' etc.
}
