📒 笔记文档

步骤

• 确定springboot版本，这个很重要，微服务项目springcloud和spirngboot版本有一定关系。
• 确认JDK版本，springboot和jDK版本有关系
• springcloud版本确认，通过maven版本管理引入spirngcloud。spring-cloud-dependencies
• 引入spring-cloud-alibaba-dependencies微服务组件的作用，alibaba有更好的配置中心nacos，熔断限流Sentinel，更好的消息中间件MQ。
• 子项目中就能直接使用spirngcloud相关的组件，比如alibaba的nacos，springboot本来就支持的gateway，loadbanlace等组件，而且子项目引入相关依赖不需要指定版本。
• 设置打包项目，版本
