Customize your Spring Boot experience by writing your own Spring Boot starter
summary
Shows how to build a reusable Spring Boot starter that actually works: a two-module layout (optional dependency starter + auto-configure) using spring.factories to register auto-configuration, Java @Configuration beans and conditionals such as ConditionalOnClass, ConditionalOnMissingBean and property checks to avoid breaking apps. Demonstrates a Thymeleaf custom dialect that renders an HTML banner, a cache-backed banner variant guarded by a custom condition built with AllNestedConditions, and uses the actuator autoconfig report to prove which configurations match.
