This section refers to '''property injection''', or the process through which external data that is provided to the application runtime at startup or while it is running, in form of properties, environment variables and other means, and which can potentially modify the behavior of the application. The component configuration, or bean wiring, is addressed in the "[[Spring_Dependency_Injection_and_Inversion_of_Control_Container_Concepts#Configuration_Model|Dependency Injection and Inversion of Control Container Concepts - Configuration Model]]" section.

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.

Profile

TODO

  • How do I read the effective values of all configuration properties during testing and at runtime?
  • You can figure out the active profile from within a Spring application by @Autowire-ing org.springframework.core.env.Environment and inspecting it.
