#从头搭建spring cloud + spring cloud alibaba踩坑日志<一>

报红不一定报错
报红不一定报错
报红不一定报错

版本对应选择

spring cloud与spring cloud alibaba与spring boot的版本对应可以对应github选择
github.com/alibaba/spr…
我的选择是

spring-boot	spring-cloud	spring-cloud-alibaba
2.6.11	2021.0.4	2021.0.4.0

踩的坑

• 父工程没有写packaging标签
• 由于父工程使用maven创建，创建时没有写parent标签
• 子工程启动的时候bootstrap.yml没生效：加上spring-cloud-starter-bootstrap依赖
• 还有各种奇怪的报红，依赖找不到：建议不要理会，实际以项目启动报错为准
