A large Java learning repository packed with hands-on example modules covering six Spring-related technology stacks: Spring Boot 2.X, Spring Cloud, Spring Cloud Alibaba, Dubbo, distributed message queues, and distributed transactions.
A large Java learning repository packed with hands-on example modules covering six Spring-related technology stacks: Spring Boot 2.X, Spring Cloud, Spring Cloud Alibaba, Dubbo, distributed message queues, and distributed transactions.Is this a working app or a tutorial series?It is not a single runnable app but a collection of standalone 'lab' Maven modules (lab-01, lab-23, labx-05, etc.), each demonstrating one technology and paired with a companion blog article explaining it.
It is not a single runnable app but a collection of standalone 'lab' Maven modules (lab-01, lab-23, labx-05, etc.), each demonstrating one technology and paired with a companion blog article explaining it.How do I run one of the labs?Clone the repo, pick the lab module you want (e.g. lab-11-spring-data-redis), and uncomment its entry in the root pom.xml, since every module is commented out by default because the repo has 50000+ lines of example code.
