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. 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

How to deploy Spring Boot Application in Docker?

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

Spring Boot MVC REST Annotations With Examples

by devs5003 - July 24, 2023January 9, 20241

In this article, we will discuss on 'Spring Boot MVC REST Annotations With Examples'. Needless to say, these annotations are very important for creating a web application in Spring Boot. If you want to learn all annotations which are generally used in a Spring Boot Project, kindly visit our article 'Spring Boot Annotations with Examples'. Let's discuss about 'Spring Boot MVC REST Annotations With Examples' here only. Spring Boot MVC REST Annotations With Examples Spring MVC and Spring REST are two different aspects of the Spring Framework. These both deal with building web applications, but they fulfil different purposes and use slightly different sets of annotations. Spring MVC (Model-View-Controller) is a design for building web applications that follow the traditional Model-View-Controller pattern. We

Spring Boot Bean Annotations With Examples

In this article we will discuss on 'Spring Boot Bean Annotations with Examples'. Needless to say, these annotations play a crucial role in creating basic as well as enterprise level Spring Boot Applications. If you want to learn all annotations which are generally used in a Spring Boot Project, kindly visit our article 'Spring Boot Annotations with Examples'. Let's discuss about 'Spring Boot Bean Annotations with Examples' here only. What is a Java Bean? Java Bean is a simple java helper class, used to transfer data between classes or applications. Typically, it doesn't act as a main class, but like postman or delivery boy between two classes. It doesn't contain any logic. There are some standard guidelines to develop a Java Bean class: 1.

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 Redis CRUD Example

by devs5003 - June 26, 2023November 15, 20256

As a Java developer, if we talk about data layer, we can’t develop an insightful application without the use of CRUD Operations. We might have developed CRUD operations multiple times using a relational database such as My SQL, SQL Server, Oracle etc. However, this time we are going to use a NoSQL Database which is different than a relational database. Here, we will use the Redis database to implement CRUD operations using Spring Boot. Hence, our article for the discussion is 'Spring Boot Redis CRUD Example'. 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

Spring Boot MongoDB Java Tutorial With Examples

by devs5003 - June 10, 2023April 9, 20264

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
