How to reduce boilerplate code in REST API Spring Data REST

by devs5003 - October 20, 2023June 19, 20255

In previous article on REST API Development, we have already seen that how we can develop a REST API with minimum lines of code. Still, we have more scope to reduce lines of code using a concept called 'Spring Data REST' in Spring Boot. So, our title of the article is 'How to reduce boilerplate code in REST API Spring Data REST'. In Spring Data REST concept we don't have to write even RestController and its methods. The Spring Data REST dependency will take care of it using HATEOAS (Hypertext as the Engine of Application State). HATEOAS project is a library of APIs that we can use to easily create REST representations. Spring Data REST provides hyperlinks to access REST operations

MCQ on Spring and Hibernate

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. Examiners, test conductors are encouraged to make use

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

Spring Boot MVC REST Annotations With Examples

ORM In Java

by devs5003 - July 12, 2023May 1, 20250

In software development, in order to build robust and scalable applications, effective data management is very important. In contrast to the traditional JDBC technique, Object-Relational Mapping (ORM) plays an important role in simplifying database operations by reducing the gap between object-oriented programming and relational databases. In this article, we will explore ORM In Java (ORM in the context of Java), its basic concepts, and how it improves productivity and maintainability in application development. Hibernate, one of the most popular ORM frameworks, offers a comprehensive set of features and has a large community of users. EclipseLink, another notable framework, is known for its performance optimizations and support for Java EE standards. Additionally, frameworks like Apache Cayenne and MyBatis provide alternative approaches to

Spring Boot MongoDB Java Tutorial With Examples

by devs5003 - June 10, 2023November 11, 20254

As a Java developer, we can't develop an insightful application without the use of a database software. Traditionally, we use a relational database to work with an application. Of course, A relational database is a structured database and contains multiple tables to maintain meaningful relations between them. Additionally, it uses SQL like queries to operate with data stored in the tables. In contrast, suppose we have to work with a large amount of unstructured data which is not beneficial to store in the form of tables, keeping other factors in mind as well, then how will we store our data? The simple answer is 'we should use MongoDB' in that case. Further, you might even have some other questions in your
