Exploring Spring Boot Clients: A Comprehensive Overview
summary
Starts with a surprising history: the jdbc template dates to 2001 (predating Spring), Spring is ~20 years old and Spring Boot ~10, and templates still run in production. Shows concrete options: use the new jdbc client (Spring Boot 3.2 auto-configures it) instead of raw templates, prefer the synchronous rest client (defaults to the Java HTTP Client) over new RestTemplate, and use the reactive web client only if you accept Reactor. Demonstrates interface-based proxy clients, Builder-based configuration, and when each approach actually simplifies error handling, resource cleanup, or token refresh.
