docker 踩坑日记The last packet sent successfully to the server was 0 milliseconds ago.
The last packet sent successfully to the server was 0 milliseconds ago.
今日遇到了这个坑,看似平白无奇。
首先,我定位到是数据库的问题。
做了如下处理:
- 仔细查看代码中数据库url的配置问题。
- 查看数据库的权限问题。
- 去tomcat的container ping了一下。
发现都没问题。
我他么。。 卡了一天。。 灵机一动,重启了一下mysql这个container,好使了。
总结一下就是:
在container做了修改后,必须重启一下,才能生效。
