SpringMVC+Mybatis 用阿里的 druid 做数据库线程池 出现的莫名其妙的问题 求救

2016-01-29 00:09:07 +08:00

环境是 SpringMVC4.2.4+MyBatis3.3,用 maven 搭建的环境，用 JDK7 和 Tomcat7 ，系统 mac

之前一直是这个环境在使用，今天突然发现启动 tomcat ， druid 曝出了

The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.

去搜索引擎都了解了下，很多都是上线后 8 小时或更久出现，因数据库回收了连接，系统缓存不知导致？目前我的情况是启动 Tomcat 就会出现，无法正常启动项目，尝试过：

都无效。

最后尝试用 jdk8 和 tomcat8 就可以顺利启动并连接数据库成功，那现在很疑问的猜测 jdk7 坏了？但是强制 rm 掉 jdk7 （ mac 当时能想到的方法就只有这个），重新去官网下载了 jdk7 的 pkg 包安装，还是报一样的问题。

那现在请问大家还有什么其他排查思路吗？或者有遇到类似情况的？

下提有报错日志(最下面)， applicationContext.xml ， spring.xml,web.xml,

spring.xml

@ghostsf delete id=0 删表数据，遇到过两次，无法重现 bug ，一次是大项目中出现，一个就是我现在这个做的小的。好几次内存泄露严重。

mysql-connector 换低版本的试试，你用的最新版怕是有问题，另外你应该把 myabtis 的配置贴出来， mysql 的连接加上 autoReconnect=true

@li24361
@sherlocktheplant
是 SS 的问题，虽然网络设置没有设置全局代理。但是 jdk7 的 socket 还是走了代理，然后出现了问题。
为啥-。-jdk8 没这个问题呢，迷醉。重置了网络设置就好了。


@ququzone 这不是生产环境。是一启动就有。
@Infernalzero mybatis 其实没有什么配置就开启了 cache 。
@zacard 解决了，出现问题时是用 13
@Infernalzero 解决了， thk
