Quartz Schedular in Grails - grails

Question

I have OperationLog class and I create 1000 records with the information which supplied by another class called Validator.
def list = {
params.max = Math.min(params.max ? params.int('max') : 10, 100)
[operationLogInstanceList: OperationLog.list(params), operationLogInstanceTotal: OperationLog.count()]
}
def create = {
def operationLogInstance = new OperationLog()
operationLogInstance.properties = params
operationLogInstance.validator = Validator.get(params.validatorId)
operationLogInstance.operation = Operation.get(params.operationId)
return [operationLogInstance: operationLogInstance]
}
def save = {
int i = 0;
1000.times {
def operationLogInstance = new OperationLog(params)
operationLogInstance.validator = Validator.get((i));
operationLogInstance.save(flush: true)
i ++;
}
redirect(action: "list")
}
}
My question is this. How can I create these records one by one with the help of quartz scheduler and each should be saved in 5 minutes.
Note: I created a job (MyJob.groovy) already. I have my execute and triggers method all empty.

Answer 1

As far as I understand you, you get data from the user? And you want to save this data 1000 times, every 5 minutes one?
So you want to call a service to do this (the data as a parameter)?
So this could be done via Threads (anywhere, should also work in controllers...
Thread.start {
1000.times {
def operationLogInstance = new OperationLog(params)
println(params.validator)
operationLogInstance.validator = Validator.get(params.validator.id);
operationLogInstance.save(flush: true)
}
wait(300000)
}
May be there is a OperationLog.withSession { ... } necessary around it.
Alternatively you could feed a quatz job (using a service that save the logs you want to save...)looking like this:
class OperationLogJob {
static triggers = {
simple name:'Operation Save', startDelay:0, repeatInterval:300000
}
def sessionRequired = true
def concurrent = false
def operationsLogService
def execute() {
def operationLogInstance = operationsLogService.getLogsToSave()
if(operationLogInstance) {
operationLogInstance.validator = Validator.get(params.validator.id);
operationLogInstance.save(flush: true)
}
}
}
}
The operationsLogService.getLogsToSave() method returns (and deletes) a value from a stack that you can fill in the controller method (eg. 1000.times {operationsLogService.addLog(log) })
