Lombok Spring Boot And Lombok Annotations

by devs5003 - September 16, 2023December 11, 202517

While developing a project in Java, we tend to repeat the similar kind of code for each class we create. Such kind of repetitive code is generally called boilerplate code. Our next question might be like 'Can we get rid of such multiple lines of code in real time development?' Then answer of your question is simply 'Yes'. The next question should be 'How can we reduce such kind of boilerplate code?' Now the answer is 'with the help of Lombok API, some people call it Lombok Project'. However, as the title "Lombok Spring Boot and Lombok Annotations" suggests, our focus in this article will be on the Lombok API Annotations. Furthermore, the 'Lombok API' is highly being used in the

MCQ on Spring and Hibernate

by devs5003 - September 14, 2023May 5, 20251

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 article, we will talk about 'MCQ on Spring and Hibernate'. Answer & Explanation of each question are provided next to each question. These questions are newly introduced on the web for the first time, having been created with significant 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 page as a link rather than copying the whole questions.

Sealed Class In Java

by devs5003 - August 28, 2023May 1, 20250

Java has transformed remarkably over the years, introducing new features and enhancements to make the language more robust and secure. One such feature introduced in Java 15 as a preview is the 'sealed' keyword for classes and interfaces. It was included in Java 17 as a final feature. Sealed classes and interfaces provide improved control over the inheritance hierarchy. In this article, we will explore sealed class in Java & sealed interfaces, including their syntax, rules, code examples, and related concepts. What is a sealed keyword in Java? In Java, the sealed keyword is used to control and restrict the inheritance hierarchy of classes and interfaces. It allows us to specify which classes or interfaces are allowed to extend or implement a

logback xml Configuration Examples

by devs5003 - August 23, 2023November 9, 20252

When it comes to implementing Logging feature in our application, especially in Spring Boot based applications, Logback comes into the picture. Typically, logback configuration comes in the form of XML file (logback.xml) for the developers to use. It provides a powerful, responsive, and reliable solution in configuring the application's logging. It ensures consistent and customizable logging behavior, simplify maintenance, and offers dynamic adjustments. All of them are crucial for effective application monitoring, debugging, and troubleshooting. Logback is an open-source project with a strong engagement to reliability and robustness. Logback offers a broad range of configuration options through logback.xml, allowing us to customize our logging setup to accurately match our application's requirement. We can control log levels, formats, destinations, and filtering rules.

Logger In Spring Boot

by devs5003 - August 15, 2023November 9, 20251

We often pay very less attention on the implementation of logging during the development phase of an application. On the other hand, it becomes mandatory when we deploy the application in production. Sometimes we just insert 'System.out.println' statements as a shortest path, which is a bad practice in the production level applications. Logging serves as a crucial tool for developers by providing insights into the inner workings of an application. It also assists in diagnosing issues, and helping in the overall monitoring and maintenance of the software. In this article, we will learn logger in Spring Boot and related concepts with extensive amount of examples. What is a Log? In software development, "log" represents a report containing the history of events, activities, or

by devs5003 - July 29, 2023April 7, 20264

Have you ever observed that an application runs successfully in development environment, but the same application with the same code creates multiple issues while running in the production environment? If not, you may observe this in near future when you follow traditional deployment procedure. Generally in traditional deployment, we copy the code from development server to the production server and carry out some other configurations. Further to avoid issues generated during production deployment, we should once think of Docker concept. Therefore, we are going to learn 'Spring Boot Docker: How to deploy Spring Boot Application in Docker?'. If you are a Java developer working in IT industry for the last few years, then you must have heard about Docker. Docker and
