The text provides a detailed guide on setting up a sample travel application using Couchbase Server and Spring Boot for Java, which was demonstrated at Couchbase Connect 2015. It outlines the prerequisites, including Apache Maven, JDK 1.7, Couchbase Server 4.0, and an IDE like IntelliJ IDEA. The process involves creating a new Java project, configuring Maven dependencies, setting up a Couchbase cluster and bucket, and implementing RESTful APIs for user registration, login, and flight information retrieval. It also covers handling Cross Origin Resource Sharing (CORS), creating database interaction classes, and testing the API endpoints using cURL. The guide concludes by suggesting the potential for integrating a front-end using frameworks like AngularJS, with the full project available on Couchbase Labs' GitHub channel.
