Create a Cron Using Cron Expressions

Use this SDK to implement crons to schedule the submission of jobs to job pools. However, the configuration of the cron will be defined using regex-like expressions called Cron Expressions.

Ensure the following packages have been imported:

    

        
copy
        

            

        
    
    

         import com.zc.component.jobscheduling.beans.cron.ZCCronDetails;
import com.zc.component.jobscheduling.beans.cron.ZCCronBuilder;
import com.zc.component.jobscheduling.beans.job.ZCJobBuilder;
import com.zc.component.jobscheduling.beans.job.ZCJobMetaDetail;
import org.json.simple.JSONObject;

    

    

        
copy
        

            

        
    
    

         // generate function job meta
ZCJobMetaDetail jobMeta = ZCJobBuilder.functionJobBuilder() // get function job builder
    .setJobConfig(2, 15 * 60 l) // set job config - job retries => 2 retries in 15 mins (optional)
    .setJobpoolName("functions_jobpool") // set the name of the function jobpool (optional) (either jobpoolId or jobpoolName is mandatory)
    // .setJobpoolId(1234567890L) // set the Id of the function jobpool (optional) (either jobpoolId or jobpoolName is mandatory)
    .setTargetName("target_function") // set target function's name (optional) (either TargetName or TargetId is mandatory)
    // .setTargetId(1234567890L) // set the target function's Id (optional) (either TargetName or TargetId is mandatory)
    .setParams(new JSONObject() {
        {
            put("arg1", "job");
            put("arg2", "test");
        }
    }) // set params to be passed to target function (optional)
    .setJobName("job_name") // set job name
    .build(); // build job meta

// generate cron details
ZCCronDetails expressionCronDetails = ZCCronBuilder.zcExpressionCronBuilder() // get expression corn builder
    .setCronStatus(true) // set cron as enabled
    .setCronExpression("0 0 * 1 1") // set the UNIX cron expression
    // .setTimezone("America/Los_Angeles") // set the timezone (optional)
    .setCronName("expression_cron") // set cron name
    .setCronDescription("expression_cron") // set corn description (optional)
    .setJobMeta(jobMeta) // set job meta
    .build(); // build cron details

// create expression cron
ZCCronDetails expressionCron = jobScheduling.cron.createCron(expressionCronDetails);
