Play Framework 2.0。升级bonecp

Question

在Scala中有一个Play 2.0项目。我在bonecp 0.7.1数据库连接中遇到了一个已知的bug，希望将这个库升级到0.8.0版本。在/project/plugins.sbt文件中，我添加了以下内容：

resolvers += "Sonatype OSS Snapshots" at "https://oss.sonatype.org/content/repositories/snapshots/"

libraryDependencies += "com.jolbox" % "bonecp" % "0.8.0-rc2-SNAPSHOT"

但是在编译和发行版构建之后，我得到了一个包含bonecp 0.7.1的归档文件。我应该怎么做才能让Play Framework使用bonecp 0.8.0？

Answer 1

在Build.scala中appDependencies中加载项

"com.jolbox" % "bonecp" % "0.8.0-rc1",  
"org.reflections" % "reflections" % "0.9.8"

Answer 2

如果是同一个bug，我们可以通过在application.conf中添加以下代码来解决它

# There's a bug in BoneCP 0.7.1: It doesn't actually close expired 
# connections until garbage collection, so they leak. If the application 
# is quiet, garbage collection runs may be very far out (days). We work
# around it by not expiring connections.
# See https://groups.google.com/forum/#!topic/play-framework/RM1QwOFz-2A for 
# more info

db.default.maxConnectionAge=0
