This recipe guides you through the process of creating a Java Web Application using Spring Boot framework. By following this recipe, you'll learn how to set up your development environment, create a new Spring Boot project, manage project dependencies and configure your database. You'll then delve into creating your domain model, constructing repositories, developing service classes for business logic, and creating controller classes to handle HTTP requests. The recipe also covers creating dynamic web content with HTML, CSS, JavaScript, Bootstrap, and JavaServer Pages (JSP) or Thymeleaf. You'll learn how to run your application on a servlet container like Apache Tomcat, and test its functionality by accessing configured URLs in a web browser. Finally, we'll discuss adding security to your application using Spring Security to ensure safe and secure user authentication. By the end of this recipe, you'll have a fully functional, secure Java Web Application, and you'll have gained a solid understanding of how different components work together in a web application development.
Java, the language of choice for our web application, was originally developed by James Gosling at Sun Microsystems (which is now a subsidiary of Oracle Corporation) and released in 1995. It was designed to have the "look and feel" of the C++ language, but it is simpler to use and enforces an object-oriented programming model. Interestingly, Java was initially called "Oak" after an oak tree that stood outside Gosling's office. Later the project went by the name "Green" and was finally renamed "Java", from Java coffee, said to be consumed in heaps by the language's creators. Today, it's one of the most widely used programming languages especially for client-server web applications, and it has brought to life countless fascinating web apps worldwide.
