# 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](https://github.com/cloudfoundry/java-buildpack/issues/951) 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
