A comprehensive tutorial walks through building a REST API with Solon, an independent enterprise Java framework, starting from a basic greeting endpoint and extending it into a task management API backed by H2 and MyBatis-Flex. It covers Solon's architecture, dependency injection, configuration layering, HTTP handling, and testing with solon-test, drawing comparisons to Spring Boot concepts throughout. The example uses Solon 4.1.0, Java 21, Maven 3.9.16, and MyBatis-Flex 1.11.8, with full source code available on GitHub.
