Java Buildpack Auto-Reconfiguration

This repository contains the auto-reconfiguration functionality for Spring auto-reconfiguration.

NOTE: This project has been deprecated and is in maintenance mode. We will continue to release security-related updates but will not address enhancement requests. It will be archived after Dec 2022. Refer to this issue to log comments.

What is Auto-Reconfiguration?

Auto-reconfiguration consists of three parts.

1. it adds the cloud profile to Spring’s list of active profiles
2. it exposes all of the properties contributed by Cloud Foundry as a PropertySource in the ApplicationContext
3. it re-writes the bean definitions of various types to connect automatically with services bound to the application.

The types that are rewritten are as follows:

Bean Type	Service Type
com.datastax.driver.core.Cluster	Cassandra Service
javax.sql.DataSource	Relational Data Services (e.g. ClearDB, ElephantSQL)
org.springframework.amqp.rabbit.connection.ConnectionFactory	RabbitMQ Service (e.g. CloudAMQP)
org.springframework.data.mongodb.MongoDbFactory	Mongo Service (e.g. MongoLab)
org.springframework.data.redis.connection.RedisConnectionFactory	Redis Service (e.g. Redis Cloud)
org.springframework.mail.javamail.JavaMailSender	SMTP Service
