com.liferay.portal.kernel.job.JobExecutionException：org.postgresql.util.PSQLException：这个连接已经关闭

我用的PostgreSQL 9.3和5.2的Liferaycom.liferay.portal.kernel.job.JobExecutionException：org.postgresql.util.PSQLException：这个连接已经关闭

系统工作正常，但一段时间后，我有我在日志文件中有连接丢失问题。

这是我在配置portal-ext.properties：

# 
# PostgreSQL 
# 
jdbc.default.driverClassName=org.postgresql.Driver 
jdbc.default.url=jdbc:postgresql://192.168.2.3:5432/portal 
jdbc.default.username=postgres 
jdbc.default.password=postgres

，我尝试添加这些行，但错误依然出现：

jdbc.default.testConnectionOnCheckout=true 
jdbc.default.preferredTestQuery=SELECT 1 
jdbc.default.acquireIncrement=1 
jdbc.default.maxIdleTime=10800 
jdbc.default.maxConnectionAge=14400 
jdbc.default.numHelperThreads=20

我无法理解错误，可能是postgresql设置或liferay连接池设置中的问题

我此行postgresql.conf中可以改变来解决这个问题：

#synchronous_standby_names = '' # standby servers that provide sync rep 
       # comma-separated list of application_name 
       # from standby(s); '*' = all

更新时间：

显示此错误日志文件中几次，但第一次出现是在一分钟后可能需要1小时。

我在Docker容器中运行Postgresql。

liferay和数据库容器在同一台物理服务器上。

我不知道为什么数据库连接在某些时候无法访问。

这是泊坞窗版本：

哇，Liferay的5.2？这是一段时间...

第一个问题是：这是否经常/每次都会出现？你能重现它还是只是一次？发生这种情况的一个常见原因是，Postgresql更新并重新启动时。如果在事务中发生这种情况，我希望Postgresql可以优雅地关闭，例如在关闭之前完成交易。

另一方面，在它再次启动之前，它将在一段时间内无法访问。即使Liferay（或连接池）确定当前连接无效（请参阅testQuery），它在服务器关闭期间将无法重新连接。如果Postgresql在不同于运行Liferay的服务器上运行的服务器上运行，它不仅可以重新启动数据库本身，还可以完全重启操作系统。自然，Liferay将在此期间失去联系。

由于您没有提供任何其他重现步骤的指示，我会说这是一个很好的开始猜测。否则需要更多信息。

感谢您的回复，我已经更新了我的问题，我使用了数据库容器，我认为postgreSQL没有与Docker一起使用的问题，这个错误在日志文件中多次显示，但是第一次出现是在一些分钟可能需要1个小时。 – franco
