緣由是由於：

雖然是spring boot和mysql使用docker-compose部署，但服務自己不識別mysql容器，應該使用實際的IP作鏈接！！

 

最重要的是，若是你打包從新上傳，屢次的執行了

docker-compose up

docker-compose stop

docker-compose rm

 

以後依舊報這個錯，緣由多是由於，雖然屢次的中止了啓動，重啓，移除，可是 實際上你的鏡像文件並無移除。

須要

docker images

查看spring boot服務的鏡像文件，使用命令移除掉，而後從新上傳jar包並從新建立鏡像才能夠。

docker rmi 鏡像名
