MicroProfile Config and Fault Tolerance

In this chapter, we will start by introducing MicroProfile Config as it is the basis for the configuration of other MicroProfile features, in addition to application-level configuration. The MicroProfile Config specification provides a common way to retrieve configuration coming from a variety of sources (properties files, system properties, environment variables, databases, and so on).

The topics we will cover include the following:

• Reading configuration from your application
• Providing additional sources of configuration to your application
• Providing conversion from plain configuration into application-specific objects
