It offers CRUD operations, role-based access, and authentication out of the box with minimal setup, providing a zero-code solution. This tutorial guides on running RESTHeart locally or via Docker, setting up authentication, and performing CRUD operations both through REST and GraphQL APIs.
Baeldung·1yStream Gatherers in Java
Java 24 introduces the Gatherer interface, enhancing Java Stream APIs by allowing more flexible intermediate operations. Gatherers facilitate custom data transformations and support asynchronous processing. The article explores built-in Gatherers and demonstrates creating custom Gatherers for diverse input-output mappings, demonstrating how these can be used for one-to-one, one-to-many, many-to-one, and many-to-many relationships.
Baeldung·1yConditional Logging With Logback
Explore the conditional logging capabilities of the Logback framework, which allow dynamic control of log outputs based on runtime conditions. The post covers the setup using Maven dependencies, the use of conditional tags in configuration files, and practical implementations with system properties. It also discusses the EvaluatorFilter for runtime expression evaluation and offers alternatives such as Spring profiles and environment-specific variables for cleaner configuration.
