## Description

This project is a comprehensive reference collection of practical implementation examples and patterns for building applications with Spring Boot. It serves as a Java web application template and a showcase for developing functional web services featuring REST endpoints, template engines, and global exception handling.

The repository distinguishes itself by providing detailed demonstrations of enterprise-grade features, including distributed locking, task scheduling, and asynchronous message exchange using brokers like RabbitMQ. It also includes reference implementations for automated API documentation and a variety of data integration patterns.

The project covers a broad range of capability areas, including enterprise authentication and security via JWT, LDAP, and third-party providers. It demonstrates extensive data storage integration across relational databases with sharding and multi-datasource routing, as well as NoSQL stores such as MongoDB, Redis, and Elasticsearch. Additional coverage includes real-time bidirectional communication systems, monitoring and observability tools, and traffic management through local and distributed rate limiting.
