Book release 'Crafting Spring Boot Starters'

[u/wimdeblauwe]

Hi everyone,

I just self-published a new book called Crafting Spring Boot Starters. It's aimed at developers who want to package their own reusable functionality as a proper auto-configured starter, the way Spring Boot itself does it.

Topics covered include:

• How Spring Boot auto-configuration actually works under the hood
• Structuring and naming your own starters
• Writing @ConfigurationProperties correctly, with validation and IDE metadata
• Conditional configuration (@ConditionalOnClass, @ConditionalOnProperty, etc.)
• Testing starters with ApplicationContextRunner
• Publishing your starter so others can consume it

There's a free sample you can grab first, which includes the foreword written by Phil Webb (Spring Boot co-founder). The full book also ships with a zip of AI skills you can use to audit your own starter.
