In this post of Spring Batch, I will explain with an example how to chain multiple ItemProcessors. For my example, I will create an ItemProcessor which will go through employee records one item at a time and filter out odd records. Below is the code of the ItemProcessor package xml.package11; import org.springframework.batch.item.ItemProcessor; public class EmployeeFilterItemProcessor…… Continue reading Chaining multiple ItemProcessor
ItemReadListener, ItemWriteListener, and ItemProcessListener Example
In this post under Spring Batch, I will explain how to create listeners during 1) reading of an item2) writing of an items3) processing of an item with an example. We create listeners by implementing the three interfaces ItemReadListener, ItemWriteListener, and ItemProcessListener. The class that implements ItemReadListener<T> interface must provide implementation for the below three…… Continue reading ItemReadListener, ItemWriteListener, and ItemProcessListener Example
Quartz JobDataMap Example Part 2
In the previous post under Quartz Scheduler, I explained what JobDataMap is about and I also mentioned that JobDataMap can be passed to an instance of Job through JobDetail and Trigger. In the previous post I explained with an example on how to pass JobDataMap to an instance of Job through JobDetail. In this post…… Continue reading Quartz JobDataMap Example Part 2
DefaultTask example
In all my previous post under Gradle, I have executed a task by entering the below command in the command line. gradle taskName where taskName is the name of the task to be executed If we just type gradle, the output will be as shown below Output E:\Projects\GradleConcepts\package3>gradle Starting a Gradle Daemon, 1 incompatible Daemon…… Continue reading DefaultTask example
Adding Chunk Level Listeners using ChunkListener
In this post of Spring Batch, I will explain how to add chunk level listeners. In Spring Batch, items are read one at a time, but written to file as a chunk (a collection of records written as one unit). So if total records are 100 and chunk size is 50, they will be two…… Continue reading Adding Chunk Level Listeners using ChunkListener
Excluding tasks from execution
In this post of Gradle, I will show how to exclude a particular task from execution. Below is the gradle script with three tasks build.gradle task task1 { doFirst { println ‘I am task1’ } } task task2 { doFirst { println ‘I am task2’ } } task task3 { doFirst { println ‘I am…… Continue reading Excluding tasks from execution
Executing multiple tasks
In this post of Gradle, I will show how to execute multiple tasks from command line. Below is the gradle script with three tasks build.gradle task task1 { doFirst { println ‘I am task1’ } } task task2 { doFirst { println ‘I am task2’ } } task task3 { doFirst { println ‘I am…… Continue reading Executing multiple tasks
Selecting elements that are descendants of another element

Below is the complete html code that will be used as an example 1 <html> 2 <head> 3 https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js 4 </head> 5 <body> 6 7 function selectElementByHierarchy1() { 8 var $element = $(‘#Items1 > li’); 9…… Continue reading Selecting elements that are direct children of another element
Adding Step Level Listeners using StepExecutionListener
In this post of Spring Batch, I will explain how to add step level listeners. Spring Batch provides a facility to add listeners at step level. The listeners are executed before the step is started and after the step is finished. This post explains how to create step level listeners and integrate them with the…… Continue reading Adding Step Level Listeners using StepExecutionListener
