## What it is
Greenhouse is a Java web application serving as the official reference application for Spring technologies such as Spring MVC, Security, Social, Mobile, and Integration. It also provided community features like member sign-up, badges, event management, and social network connections.

## Use cases
- learn how to build a full web application with Spring MVC and Spring Security
- see an example of OAuth-based social login with Twitter, Facebook, and LinkedIn
- study a reference implementation of Spring Social and Spring Mobile
- find sample code for Spring Integration and email templating
- understand how to structure a Spring web app deployed to Tomcat

## When to choose
- you are maintaining or studying legacy Spring projects and want a historical reference implementation
- you want to see how Spring Social, Mobile, and Security were used together in a real app

## When to avoid
- you are starting a new Spring project and want current best practices
- you need actively maintained software with recent releases and support
- you use modern Spring Boot instead of classic Spring MVC with WAR deployment

## Facets
- artifact type: application
- maturity: abandoned
- function: web-framework, auth, http-server, templating, middleware
- domain: web-development, developer-tools, education
- platform: jvm, cross-platform
- tags: spring-framework, reference-application, spring-social, spring-security, oauth, sample-app, archived, web-server
