Spring MVC Practices

Used Dependency Versions

Project: spring-mvc-xml(XML Configuration)

This configuration approach utilizes XML files to configure Spring MVC components such as controllers, view resolvers, and handler mappings. It's a traditional method where beans and their dependencies are defined in XML files, offering flexibility and separation of concerns. Spring MVC XML config.

In this project I practiced

• Setting up tomcat
• Spring MVC configuration using xml
• JSP, EL & Bootstrap
• Passing data to and from controller using Model, ModelMap, and ModelAndView.
• Initializing and logging with slf4j
• demonstrated various ways of fetching data from views:
  • Servlet API: Directly use HttpServletRequest and HttpSession.
  • @RequestParam: Extract individual query or form parameters.
  • Command/Model: Object: Bind all form fields to a JavaBean.
  • @PathVariable: Extract values from the URL path.
  • @ModelAttribute: Bind method parameters or return values to model attributes.
  • @CookieValue: Extract data from cookies.

Project: spring-mvc (Java Configuration)

This modern approach uses Java-based configuration classes to set up Spring MVC components. It leverages annotations like @Configuration and @EnableWebMvc to configure the application context, controllers, view resolvers, and other settings. It offers more concise and readable configuration compared to XML. Spring MVC Java config.

In this project I practiced

• Spring MVC using Java configuration.
• More complex form handling and persisting data using Hibernate and MySQL.
• Practiced Thymeleaf, Hibernate, Lombok, etc.
• Practiced form validation.
