Problem with persistent quartz jobs when used with Spring

Question

I configured the spring method, which previously ran a job that works fine. Now my requirement is that this work be permanent, which will work in a cluster environment. After configuring quartz as a cluster and persistent application, the application deploys the following exception:

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

I use the following versions:

• Spring version 3.1.4.RELEASE
• Quartz version 2.1.7

Update : according to the documentation MethodInvokingJobDetailFactoryBean:

JobDetails created via this FactoryBean are not serializable.

So, we are looking for an alternative approach for setting up constant work in spring.

Answer 1

I solved the problem by replacing MethodInvokingJobDetailFactoryBeanwith JobDetailFactoryBean. The configuration for it 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, for Autowirespring managed beans in my job class, mypackage.MyJobI added the following as the first line in my execution 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 this helps someone else facing the same problem.

When you use constant quartz jobs, you must set the property org.quartz.jobStore.usePropertiesto true. This forces the job data to be saved as strings instead of Java Serialized objects.

Spring, .
