SpringBoot 2.0 + Apache Dubbo 2.7.3 Latest Version Integration Scheme

Keywords: Java Dubbo Apache Spring Zookeeper

Preface

On February 16, 2018, Apache Dubbo joined the Apache Foundation incubator. On May 16, 2019, the board of directors of the Apache Software Foundation approved the graduation application of Apache Dubbo, which means that Apache Dubbo has officially become Apache's top project.

To configure

When Dubbo donates sperm to Apache, it means that the coordinates of Dubbo and spring-boot-starter have changed. Of course, the former ones are still available, but it's recommended here to use the new version.
