5 Spring Boot Features You Should Be Using

Spring Boot 3 brings a wealth of features that make building production-ready applications easier than ever.

Spring Boot architecture

1. Native compilation

GraalVM native images let you ship tiny, fast-startup binaries ideal for microservices and serverless.

Java 21 virtual threads dramatically simplify concurrent programming:

java

Thread.startVirtualThread(() -> doWork());

A unified observability API that bridges Micrometer, tracing and metrics.

Declarative HTTP clients, like Spring Data repositories but for REST:

java

@GetExchange("/users/{id}")
User getUser(@PathVariable String id);

Built-in structured logging support for easier log analysis.
