Spring Modulith: What the What?
summary
A working demo pulls USGS sensor JSON, transforms it into creek-status objects, and streams them between containers using Spring Cloud Stream with RabbitMQ and MariaDB in Docker Compose; the microservice set (producer, transformer, storage, consumers) runs end-to-end. That architecture is then consolidated into a single Spring Boot app organized by Spring Modulith modules that communicate via application events persisted by JPA; application module test and modules.verify both generate UML docs and catch illegal package dependencies.
