No, they’re not mutually exclusive.
ContextLoaderListenermanages an appcontext which is associated with the whole webapp.DispatcherServletmanages a context associated with that specific servlet. The webapp context is the “parent” of the servlet appcontext, and all beans in the webapp appcontext are visible to beans in the servlet appcontext.If you have only one servlet, there’s not many reasons to use
ContextLoaderListener. If you have multiple servlets, it’s good to put the shared beans in the webbapp context where practical, so they can be reused.
