今天早上发了一笔交易 发现服务器上报错
可见这笔交易是9点半左右发出的 入库的时候发现连接已经断掉,第一反应先计算了一下断掉的时间30516920/3600/1000 = 8.4769222222222.
大概就是半夜一点钟断掉的.我又去查了一下上一次启动项目的时间,发现现在的进程已经不是我上一次启动的进程
我重启了一下,项目问题当然就解决了,但是这肯定不是解决问题的办法,因为没办法确定过段时间会不会出现该问题.所以还是要统计一下持续时间 ....去查启动日志 发现启动日志只有今天我启动后的记录了(这里可以调查一下).很明显启动记录的日志被覆盖了.我只能从这次开始计时了.
好了,现在开始找代码中的问题.
先说一下背景 这个项目是用mybatis .数据源配置是com.mchange.v2.c3p0.ComboPooledDataSource
所以从这两点着手.之前在网上查过解决办法,就是加上autoreconnect=true,然后就发现加了没卵用.过段时间照样断连.
看了一下配置的数据源,感觉问题是出在这里,是不是少配了东西.
参考了一些网上的配置 ,最后的配置如图.问题解决告一段落,如果过段时间还出问题,本文会继续更新,毕竟还有存疑的部分呢.
