The plugin provides possibility to use Spring Cache together with Hibernate L2 cache and EHCache

Grails 4 & 3.3 supported

Interesting things:

• Provided SimpleCacheKeyGenerator can be used as Spring customCacheKeyGenerator
• CowsDBService has method for direct sql quering inside current Hibernate transaction: sqlUpdate, sqlExecute, sqlFirstRow, sqlEachRow, sqlRows
• The plugin includes EHCache administrative UI with cache size manipulation possibilities and listing cache content (/adminCache/index)

Add the following dependencies in build.gradle

repositories {
...
  maven { url "http:https://dl.bintray.com/purpleraven/plugins" }
...
}
dependencies {
...
    compile 'org.grails.plugins:grails-cows-cache-plugin:2.1'
...
}

Add following spring security configuration runtime.groovy to protect UI from access

grails.plugin.springsecurity.controllerAnnotations.staticRules = [
    [pattern: '/adminCache/**', access:["hasAuthority('YOUR_ADMIN_PERMISSION')"]]
]

Add customCacheKeyGenerator(SimpleCacheKeyGenerator) in resource.groovy (optional)

ehcache.xml can be placed in grails-app/conf directory
