How are contacty Spring mvc (DispatcherServlet/Context-param)?

No I think what is the relation between different settings of the spring context.
Here in the simplest version of all just

there are only a DispatcherServlet and sootvetsvenno Dispatcher-servlet.xml. If you wish, using init parameters you can rename it in servlet-context.xml. It's all clear.

But there, at the same web.xml add a block


And I can not understand what is the difference root-context.xml and the usual servlet-context.xml ?
Why have one if there's another ?

This is done in order not to bring down all the settings in one pile. In large projects single file with all the settings can be huge. It will be a long time to find the desired setting, if you want to edit, and easy to get confused. Therefore, the basic configuration and the announcement of bins in a single file, the security settings in other, settings to access the data in the third configuration mvc in fourth and so on. As a result, the context will be one, but the settings for it will be taken from different files. But it is better than multiple files to transfer in param-value and in root-context.xml to connect other files with the import Directive.

No, in the example above creates 2 context:
  1. Parent - raised with the help of ContextLoaderListener and files root-context.xml and spring-security.xml. This context is usually issued services, connection pooling, database, schedulers, etc.
  2. Child - For the MVC and is only available to the servlet DispatcherServlet. In the child context can see all of Bina from the parent + controller settings
