Overview

This section refers to property injection, which is the process that allows external data to be provided to the application runtime at startup or while it is running, in form of properties, environment variables and other means. The component configuration, or bean wiring, is addressed in the "Dependency Injection and Inversion of Control Container Concepts - Configuration Model" section.
