Spring Read configuration file

Description

Typically, the project will have the need to read the configuration file, which can be used for property files, XML files, and so on. Here, Spring uses the object feature to be read, and to write a sample of the property.

Demo two properties indicate items that are frequently used first, the map object of key, value relationship (similar property file), List object
