You can use this SpringBeanJobFactory to automatically autowire quartz objects using spring: import There is a pretty useful DZone article about using rabbitmq via spring-integration (a set of prebuilt pattern implementations that help with connecting things to each other). You can assign one or more threads to the listener, meaning that you should find it easy to tune the performance of the report generator. You'd have a custom listener on the queue, passing requests to a report generator whenever it runs. With the jms architecture you'd post user requests to the queue, which you'd configured to be persistent. For a messaging service I'd look at RabbitMQ, because again it's pretty simple. If you want to make it easy on yourself I'd recommend using spring-jms as a wrapper around the basic Java EE JMS api - the spring wrappers are simply simpler than basic jms. In addition to that, it also explains Batch Processing and Spring Batch extensively. This detailed article explains Spring Batch Scheduling with a relevant example. Given that you talk about queues and their persistence however it sounds a lot like your problem would fit into a simple jms model. Spring Batch processing can assist in developing robust batch processing applications and even manage event-driven operations using Spring Batch Scheduler. They aren't competing technologies, they are complimentary. You could use quartz to schedule batch jobs to run at specific times. So, quartz is a scheduler and batch is a process. You would use a quartz job if you wanted to check for new jobs every few seconds/minutes/hours/etc, and process one/many of them at that specified time interval. If all data are consumed, then a null value will be returned by this method.You would use spring-batch if you wanted to process all report requests at the same time, perhaps at night when your servers are not otherwise occupied processing real-time user requests (or even during the day during slow periods). We use it to get data by read() method. This will read string from array one by one and forward to processor. we will create a Reader.java class which implements a ItemReader interface.Create Steps: Reader, Processor and Writer There are two methods beforeJob () and afterJob ().This job will perform its task in one step and this step will have a reader that will read a string value from an array, a processor that will transform a string value in uppercase and a writer that will print transformed string on console.Ģ. JobExecutionListener provides interceptions and life-cycle methods for spring batch Jobs. We will build a job that will read a string value from an array, convert it into upper case and print on console. When all jobs are done then the batch can be declared as done. Now, the above diagram is a better description of a batch job which includes multiple jobs. Let us try to visualize a batch job with following image: The following figure define a simple batch jobĪbove image describe a job only, not a batch job.
