Spring Boot has greatly simplified how to develop applications with Spring. Its auto-configuration and many starters has fostered a Spring renaissance that makes developing Spring apps fun again!
Stormpath's Spring Boot starter is one of the most sophisticated in the land! It works with and without Spring Security, providing standard authentication flows as well as sophisticated standards compliant authorization flows (e.g. OAuth2 and OpenID Connect). Stormpath also supports adding to a Zuul gateway to secure your microservices infrastructure. Stormpath has also recently released Juiser, which allows you to auto-create an authenticated user object from an X-Forwarded-User header.
Stormpath Evangelists, Micah Silverman and Matt Raible, demonstrate the wonders of Spring Boot and Stormpath's unique starter that provides an incredible amount of functionality.
