seata启动报错

目录

一、说是druid连接失败的问题

二、有可能也是因为内存不足，

---

我遇到的问题如下：

INFO --- [ctionPool-Create-18213909] com.alibaba.druid.pool.DruidDataSource   : put physical connection to pool failed.

一、说是druid连接失败的问题

厚礼蟹！！这玩意儿反复横跳，几乎每秒报错100次+！

 解决：

这个是因为数据库是8.0版本系列的mysql，因此需要加上  cj  和  时区  ，如下：

com.mysql.cj.jdbc.Driver

store.db.url=jdbc:mysql://127.0.0.1:3306/seata?useUnicode=true&serverTimezone=Asia/Shanghai&useSSL=false

二、有可能也是因为内存不足，

这时候编辑一下你的seata-server.bat文件，内存调低试试。

 调整完：

 也可以试着清理一下后台运行的软件，实在不行可以考虑重启电脑。
