Mica Auto uses the Annotation Processor, which is not a new technology. It's been around since JDK 1.6. The Annotation Processor is a tool of javac that scans and processes annotations at compile time. Using the Annotation Processor, you can obtain information about annotations and annotated objects, and then automatically generate Java code based on annotations, eliminating manual writing and improving coding efficiency. Lombok is also famous for this technology.
It is mainly used to avoid the inconsistency between the Spring Boot main project package and the subproject or submodule package, and avoid the problem that the package cannot be scanned. .Customize the Spring Boot starter. .Subprojects in a multi-module project (adding MICA-Auto to a master project is not recommended).
- Automatically generate
spring.factories,spring-devtools.propertiesconfiguration (spring Boot starter development tools). - Generate the
FeignClientin the spring.factories for automated Feign configuration in the mica-cloud. - Generate the
Java Spiconfiguration, you need to add the@AutoServiceannotation.

Note: If you are using Lombok in your project, place the mica-Auto dependency behind Lombok。
