Java – Issue with Quartz persistent jobs while using with Spring

javaquartz-schedulerspring

I have configured a spring's method invoking job previously which is working fine. Now my requirement is to have this job as persistent which will run in a clustered environment.
After configuring the quartz as clustered and persistence, application is throwing the following exception at deployment:

java.io.NotSerializableException: Unable to serialize JobDataMap for
insertion into database because the value of property 'methodInvoker'
is not serializable:
org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean

I am using the following versions:

  • Spring version 3.1.4.RELEASE
  • Quartz version 2.1.7

Update: As per the documentation of MethodInvokingJobDetailFactoryBean:

JobDetails created via this FactoryBean are not serializable.

So, looking for some alternative approach to configure a persistent job in spring.

I have solved the problem by replacing MethodInvokingJobDetailFactoryBean with JobDetailFactoryBean. Configuration for the same is as follows:

<bean name="myJob" class="org.springframework.scheduling.quartz.JobDetailFactoryBean">
    <property name="jobClass" value="mypackage.MyJob" />
    <property name="group" value="MY_JOBS_GROUP" />
    <property name="durability" value="true" />
</bean>

However, to Autowire the spring managed beans in my job class mypackage.MyJob, I have added the following as first line in my execute method:

class MyJob implements Job {
    ...
    public void execute(final JobExecutionContext context) throws JobExecutionException {
        // Process @Autowired injection for the given target object, based on the current web application context. 
        SpringBeanAutowiringSupport.processInjectionBasedOnCurrentContext(this);
        ...
    }

}

Hope it it will help someone else facing the same issue.
