Job scheduling Framework Quartz Learning Notes (vi)-handling when job is ill (throws an exception)

We haven't gone too far to complete a job class because it's closely related to your actual application, but in your job process

What happens if an exception is made? Sir you look down ... .....

------------------------------------I'm a split line------------------------------------------------

If Sir looked at the previous few rotten dregs of the article, will know that the following will first paste code, a job class, a scheduling class.

But this time a little different is not rotten slag, but rotten more slag,-.-

Two job classes: Badjob1.java and Badjob2.java

A scheduling class: Jobexceptionexample.java

Badjob1.java[Java]  View plain copy import java.text.simpledateformat;   import java.util.date;      import org.quartz.disallowconcurrentexecution;   import org.quartz.job;    import org.quartz.jobexecutioncontext;   import org.quartz.jobexecutionexception;    import org.quartz.persistjobdataafterexecution;      @ persistjobdataafterexecution   @DisallowConcurrentExecution    Public class badjob2  implements Job {           @Override         public void execute (jobexecutioncontext context)                 throws JobExecutionException {            //  Task Execution Time             simpledateFormat dateformat = new simpledateformat ("Yyyy-mm-dd hh:mm:ss");            string jobname = context.getjobdetail (). GetKey ().

Badjob2.java [Java]   View plain copy import java.text.simpledateformat;    import java.util.date;      import org.quartz.disallowconcurrentexecution;    import org.quartz.job;   import org.quartz.jobexecutioncontext;   import org.quartz.jobexecutionexception;   import org.quartz.persistjobdataafterexecution;       @PersistJobDataAfterExecution    @DisallowConcurrentExecution    public class badjob2 implements job {           @Override        public void execute (jobexecutioncontext context)
