Using the Java SDK for Couchbase: The Basics of Get & Upsert

This tutorial provides a step-by-step guide for Java developers on how to interact with Couchbase using the Java SDK, focusing on creating and fetching JSON documents. It begins by setting up a Java development environment with necessary tools like OpenJDK and the Coding Pack for Java, followed by connecting to a Couchbase cluster using the java-client dependency in Maven. The tutorial illustrates how to connect to a Couchbase bucket and retrieve documents using document IDs, with examples from the travel-sample bucket. It also covers creating or upserting documents by forming and submitting JSON objects with unique IDs, which either adds new documents or updates existing ones. The process is demonstrated with minimal code samples, making it accessible for beginners, and concludes with a full code example and an invitation to explore further features like Query and Full-Text Search in future tutorials.
