Question

Play framework 2.1.0使用MSSQL数据库

，我们遇到了一个奇怪的问题

申请表：

db.default.url="jdbc:jtds:sqlserver://localhost:1433/PlayApp;instance=SQL2008"
db.default.driver=net.sourceforge.jtds.jdbc.Driver
db.default.user=sa
db.default.pass=test
db.default.partitionCount=1
db.default.maxConnectionsPerPartition=5
db.default.minConnectionsPerPartition=5
db.default.acquireIncrement=1
db.default.acquireRetryAttempts=1
db.default.acquireRetryDelay=5

以下例外：

--- (Running the application from SBT, auto-reloading is enabled) ---

[info] play - Listening for HTTP on /0.0.0.0:9000

(Server started, use Ctrl+D to stop and go back to the console...)

[error] c.j.b.h.AbstractConnectionHook - Failed to acquire connection Sleeping for 5ms and trying again. Attempts left: 1. Exception: null

        at scala.collection.TraversableLike$$anonfun$map$1.apply(TraversableLike.scala:244) ~[scala-library.jar:na]
[error] application -

我试图对问题进行排序，但我每次遇到此错误都需要重新启动我的Sql实例是否存在连接池问题？

任何一个人都能回答？

Answer 1

你可以尝试改变

db.default.acquireRetryDelay=5

通过

db.default.acquireRetryDelay=5 seconds

Play Framework一段时间后无法连接到DB
