Generally, all applications have some data in some form. In enterprise applications, we deal with large volume of data. Sometimes processing a single operation faster is not sufficient due to the large volume of data. This requires a robust transactional control and failure recovery mechanisms, which are complex to implement. In order to handle all this, Spring Framework provides a module 'Spring Batch' for the Batch Processing. Therefore, our topic for discussion is 'Spring Batch Tutorial'. Spring Batch Processing offers processing of data in the form of batch jobs. Spring Batch offers reusable functions for processing large volume of records. It also includes logging/tracing, transaction management, job processing statics, skip, job restart, and resource management. Spring Batch has taken care of

How to Write Spring Boot Application Properties Files
If you are a Spring Boot developer, you must have come across the 'application.properties' or 'application.yml' file. Needless to say, these files reduces your development effort by minimizing the amount of XMLs that you were writing in a standard Spring based project. Moreover, we accommodate the common properties of our project in the form of key-value pairs in these files. Therefore, it becomes more than important to know all about these files. These are application properties file with the extension of either '.properties' or '.yml'. Hence, our topic for this article is 'How to Write Spring Boot Application Properties Files'.

MCQ on Spring and Hibernate
Details on this page are a little bit different than at other pages. Rather than going through some theoretical or practical way of learning Spring & Hibernate frameworks, we will test our understanding of Spring & hibernate via solving multiple choice questions (MCQs). In this page, we will talk about 'MCQ on Spring and Hibernate'. Answer & Explanation of each question are given at the bottom of this page. You will find these questions for the first time on the web as they are created after putting a strong effort. You may also find these questions in some other websites/blogs after publishing this page. Someone who likes the questions & interested in copying the questions can just provide a reference of this

Spring Boot Annotations With Examples
Prior to Annotations, the Spring Framework's configuration was largely dependent on XMLs. Using XML configurations was not only a tedious process, but also an error-prone. If you committed any syntactical mistake in XML, sometimes it takes time to fix. But now-a-days annotations, particularly Spring Boot Annotations provide us remarkable capabilities in configuring Spring Framework's behavior. Moreover, Annotations caused major changes in programming style and slowly making the XML-based configurations outdated. The Java Programming introduced support for Annotations from JDK 1.5. However Spring Framework started supporting annotations from the release 2.5. Obviously, we are going to discuss about Spring Boot Annotations With Examples and their usages. Here in this article on 'Spring Boot Annotations With Examples', we will discuss about all annotations
