Java Buildpack Auto-Reconfiguration

This repository contains the auto-reconfiguration functionality for Spring and Play Framework auto-reconfiguration. It also contains a replacement Play Framework JPA Plugin that can be properly auto-reconfigured.

What is Auto-Reconfiguration?

Auto-reconfiguration consists of three parts.

it adds the cloud profile to Spring's list of active profiles
it exposes all of the properties contributed by Cloud Foundry as a PropertySource in the ApplicationContext
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
`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.orm.hibernate3.AbstractSessionFactoryBean`	Relational Data Services (e.g. ClearDB, ElephantSQL)
`org.springframework.orm.hibernate4.LocalSessionFactoryBean`	Relational Data Services (e.g. ClearDB, ElephantSQL)
`org.springframework.orm.jpa.AbstractEntityManagerFactoryBean`	Relational Data Services (e.g. ClearDB, ElephantSQL)
