Spring Cloud Annotations With Examples

by devs5003 - 0

Introduction of new Annotations reduces the development efforts day by day. Needless to say, as a developer, we can't think of the development of an enterprise level application without using annotations, especially in applications that use Spring or related frameworks. Furthermore, we come across the Spring Cloud framework when we develop a Microservices based application. Now-a-days, there is a high demand of Microservices based applications in the industry. Therefore, it becomes very crucial to know the annotations used in Spring Cloud. Hence, in this article, we are going to discuss 'Spring Cloud Annotations With Examples'. We can't deny from the fact that the cloud is the future and, in the upcoming days, we will be seeing a lot of Java based

How to reduce boilerplate code in REST API Spring Data REST

by devs5003 - 5

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

We can take help of it on performing some

Lombok Spring Boot And Lombok Annotations

by devs5003 - 17

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 - 1

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

Sealed Class In Java

by devs5003 - 0

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 - 2

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.
