MySQLNonTransientConnectionException : Communications link failure during commit(). 事务解析未知

标签 mysql svn jdbc ant sonarqube

每当我在 Hudson 中构建作业时，在尝试将结果存储到数据库中时总是会在最后失败。整个工作通常需要大约一个小时的时间来构建和失败。

源文件存储在SVN服务器上，可在本地下载和编辑。一旦我验证作业能够在本地成功构建，我就将所有更改提交到 SVN。

我最近改用了一种基于 ANT 的方法，该方法使 ant 目标与 session 审阅者相匹配。所以我创建了一个sonar.xml文件，其中包含一个名为sonar_scan的目标，在项目的build.xml文件中调用。

我已将 net_read_timeout、net_write_timeout 和 innodb_lock_wait_timeout 设置为 10 分钟，而不是它们的默认值 60 秒或更短。 wait_timeout 设置为 8 小时，所以我知道 wait_timeout 不是问题。

  • 我使用的数据库是mysql version 5.6.25
  • 我使用的 Sonar 版本是 5.1

我收到的完整错误信息是:

我到处寻找可能的解决方案，但到目前为止我还没有找到。如果有人可以建议我还没有做过的事情，那么我将不胜感激。

最佳答案

网络不稳定

重现代码:

con.query()
sleep(10) //when sleep shutdown your network 
conn.roolback()
