Unleash the power of your applications with Micronaut and GraalVM
summary
Shows a working Micronaut service assembled with Micronaut Data (JDBC repo), H2 and Flyway and compiled with GraalVM Native Image into a native executable in about one minute. Claims compile time DI via annotation processors so runtime has no reflection or proxying, resulting in tiny stack traces, much lower memory, and blistering startup like 31 milliseconds for the demo binary. Demonstrates HTTP endpoints, an integration test that runs in 437 ms, and how Micronaut 4 targets Java 17 with smaller optional dependencies.
