我正在使用Play 2.4在Scala中开发一个Web应用程序，它需要连接到DB2，Vertica，MySQL等。
Vertica和MySql配置工作正常，但我无法连接到DB2，版本10.5，修订包5。
这是application.conf设置
db.db2.driver=com.ibm.db2.jcc.DB2Driver
db.db2.url="jdbc:db2://host:port/database"
db.db2.username="user"
db.db2.password="pass"
db.db2.logStatements=false
db.db2.initSQL="select 1 from sysibm.sysdummy1"
我正在使用以下类型4 JDBC驱动程序：
db2jcc.jar db2jcc4.jar
但是，我收到以下错误（为长错误消息道歉）：
Unexpected exception
CreationException: Unable to create injector, see the following errors:

我猜你错过了这个：
引起：java.sql.SQLException：不支持JDBC4 Connection.isValid（）方法，必须配置连接测试查询
由于您同时提供JDBC 3.0（db2jcc.jar）和JDBC 4.0（db2jcc4.jar）驱动程序，因此无法保证将加载两个驱动程序中的哪一个。
确保JDBC 4功能仅在类路径中保留db2jcc4.jar。
