Play / Slick：SQLTimeoutException：等待连接1001ms后的超时

时间：2015-11-16 14:37:04

标签： postgresql playframework slick playframework-2.4 play-slick

我创建了一个空的（激活模板play-scala）使用PostgreSQL 9.4数据库播放2.4.3应用程序并尝试使用Slick 3.1.0，但是它引发了错误：

play.api.UnexpectedException: Unexpected exception[SQLTimeoutException: Timeout after 1000ms of waiting for a connection.]

这是我的build.sbt：

name := """et"""

version := "1.0-SNAPSHOT"

lazy val root = (project in file(".")).enablePlugins(PlayScala)

scalaVersion := "2.11.7"

libraryDependencies ++= Seq(
    cache,
    ws,
    "com.typesafe.slick" %% "slick" % "3.1.0",
    "org.slf4j" % "slf4j-nop" % "1.6.4",
    "com.typesafe.play" %% "play-slick" % "1.1.1",
    "com.typesafe.play" %% "play-slick-evolutions" % "1.1.1",
    "org.postgresql" % "postgresql" % "9.4-1205-jdbc42"
)

resolvers += "scalaz-bintray" at "http://dl.bintray.com/scalaz/releases"

routesGenerator := InjectedRoutesGenerator

和application.conf：

play.evolutions.db.default.enabled = true

slick.dbs.default.driver = "slick.driver.PostgresDriver$"
slick.dbs.default.db.driver = "org.postgresql.Driver"
slick.dbs.default.db.dataSourceClass = "slick.jdbc.DatabaseUrlDataSource"
slick.dbs.default.db.properties.driver = "org.postgresql.Driver"
slick.dbs.default.db.url = "jdbc:postgresql://localhost:5432/mydb"
slick.dbs.default.user = "postgres"
slick.dbs.default.password = "postgres"

根据文档（https://www.playframework.com/documentation/2.4.x/PlaySlick），一切都应该没问题，那么这里可能出现什么问题呢？

更新：我注意到的一件重要事情 - 我只有一次数据库演变，一旦删除它，错误就消失了。我确实需要进化，所以问题仍然存在。

UPDATE2：所以我在github上发现了一些相关问题，但没有解决方案： https://github.com/playframework/play-slick/issues/275 https://github.com/playframework/playframework/issues/4675

问题在于配置，这是一个有效的例子：

slick.dbs.default.driver = "slick.driver.PostgresDriver$"
slick.dbs.default.db.driver = "org.postgresql.Driver"
slick.dbs.default.db.url = "jdbc:postgresql://localhost:5432/mydb"
slick.dbs.default.db.user = "postgres"
slick.dbs.default.db.password = "postgres"

答案 1 :(得分：3)

我在Play 2.5.9和Slick 3.11中遇到过这个问题。我通过添加slick.dbs.default.db.properties.url来解决它：

slick.dbs.default.db.url="jdbc:postgresql://<hostname>:<port>/<db>"
slick.dbs.default.db.properties.url="jdbc:postgresql://<hostname>:<port>/<db>"

答案 2 :(得分：0)

请注意，如果您输入了错误的登录详细信息，它仍将作为超时而非Auth错误或类似信息返回。
