Java 突然间，我用mariadb（mysql）和jdbc得到了一个StackOverflower错误，为什么？

我刚刚重建了我公司的一个应用程序 （在生产过程中工作良好，主分支机构没有任何变化）， 突然间我得到了一个

java.lang.StackOverflower错误

。 我的同事也在他的机器上构建了这个应用程序，他也得到了同样的错误，这很奇怪，因为我们使用单独的本地

MySQL

数据库

最近是否更改了

mariaDB

的依赖项

以下是一个完全例外：

如果代码中真的没有差异， 然后，本地数据库实例中的数据与生产数据库实例中的数据之间存在差异

在MYCOMPANY.liferay.view.singleTimeline.SingleTimelineImpl或任何使用它的东西中，都有一个无限循环（或只是一个超深循环）

当您要求人们“请查看我的异常转储以帮助我”时，请考虑包含整个异常转储。

我认为罪魁祸首不是

MySQL

/

MariaDB

，但是中间件

EclipseLink

…永无止境地循环

refreshgraphicalTimeline

…

RecalCandDateIfOverlappingInterval

。

getGraphicalTimeline

。@Usagi您能指定吗？@Carlos谢谢，但这些是不同的时间线
