spring-projects/spring-boot — reverse-engineered prompt

Build me a Java framework that makes it really easy to create production ready Spring based apps without a lot of setup. I want developers to be able to start a simple web service fast, run it as a normal jar, and avoid XML configuration or generated code.

It should make sensible default choices, but still let people change things when their app gets more serious. Include common things people expect in real services, like an embedded web server, configuration from outside the app, health checks, metrics, and a path for adding security. Also include a small command line tool for running simple Spring scripts.

Please include a tiny Hello World web example, clear getting started docs, and a way to build and test everything locally. Look up current Spring and Java docs online if you need to.
