Maven dependency spring-web vs spring-webmvc
spring-web provides core HTTP integration, including some handy Servlet filters, Spring HTTP Invoker, infrastructure to integrate with other web frameworks and HTTP technologies e.g. Hessian, Burlap.
spring-webmvc is an implementation of Spring MVC. spring-webmvc depends on on spring-web, thus including it will transitively add spring-web. You don't have to add spring-web explicitly.
You should depend only on spring-web if you don't use Spring MVC but want to take advantage of other web-related technologies that Spring supports.
From the official doc:The spring-web module provides basic web-oriented integration features such as multipart file upload functionality and the initialization of the IoC container using Servlet listeners and a web-oriented application context. It also contains an HTTP client and the web-related parts of Spring’s remoting support.
The spring-webmvc module (also known as the Web-Servlet module) contains Spring’s model-view-controller (MVC) and REST Web Services implementation for web applications. Spring’s MVC framework provides a clean separation between domain model code and web forms and integrates with all of the other features of the Spring Framework.
The spring-webmvc-portlet module (also known as the Web-Portlet module) provides the MVC implementation to be used in a Portlet environment and mirrors the functionality of the Servlet-based spring-webmvc module.
