Grails .findBy doesn't work with redis

Question

I have a very simple test case I am using to try to understand redis. I did install-plugin redis-gorm.

Domain Object:

class BenchGroup {
  String groupName
  /*static mapWith = "redis"
  static mapping = {
    groupName(index:true)
  }*/
  static constraints = {
  }
}

Bootstrap Code:

def everyoneGroup = new BenchGroup(groupName:'everyoneGroup')
everyoneGroup.save()
if(everyoneGroup.hasErrors()){
  println everyoneGroup.errors
}
println everyoneGroup
def dammit = BenchGroup.findByGroupName('everyoneGroup')
println dammit

When I leave the redis map line commented it uses HSQL and outputs this:

stupidbenchmarks.BenchGroup : 2
stupidbenchmarks.BenchGroup : 2

When I switch to redis it does this:

stupidbenchmarks.BenchGroup : 2
null

ie .findBy doesn't work.

Hibernate在执行查询之前会进行刷新（在本例中为findByGroupName ），但是NoSQL GORM Datastore实现尚未实现（因此），因此我假设您只需要刷新就可以将保存的实例推送到数据存储中，以便查询将其提取：

everyoneGroup.save(flush: true)
