JavaWeb is a Java technology-based Web development model for building dynamic and interactive Web applications. It is a technology stack for developing web applications using the Java language, including Java Servlet, JavaServer Pages (JSP), JavaServer Faces (JSF), etc. JavaWeb provides a set of standard APIs and development models, enabling developers to process HTTP requests and responses, and build database connections, business logic processing, page rendering and other functions.
Spring is an open source Java framework that provides a comprehensive set of enterprise-level application development solutions. It simplifies many common tasks in the Java development process, such as dependency injection, aspect-oriented programming, transaction management, etc. The Spring framework contains multiple modules, which can be selected and integrated according to needs. The core module is the Spring core container, which is responsible for managing the life cycle and configuration of Java objects.
Spring MVC is a module in the Spring framework for developing web applications based on the MVC (Model-View-Controller) pattern. It provides a well-structured framework for processing web requests and responses, and mapping requests to corresponding controller, view, and model components. Spring MVC enables developers to better organize and manage code and achieve scalable web applications by separating the different layers of the application.
Spring Boot is a rapid development framework based on the Spring framework, designed to simplify the configuration and deployment of Spring applications. It provides a convention-over-configuration approach that reduces developer effort through automatic configuration and default values. Spring Boot also integrates an embedded web server, making it easier to build stand-alone, runnable web applications. It also supports automatic configuration of common functions such as database, message queue, security, etc., enabling developers to focus more on the implementation of business logic.
Therefore, JavaWeb is a technology stack for developing Web applications, Spring is a comprehensive enterprise-level application development framework, Spring MVC is the Web development module of the Spring framework, and Spring Boot is a rapid development framework based on the Spring framework. They can be used in conjunction with each other to provide functions at different levels and domains to help developers build Java Web applications more efficiently.
