播放，Ebeans：启动具有多个数据库的应用程序时出现 NullPointerException
Play, Ebeans: NullPointerException when starting application with multiple DBs
我在尝试启动需要能够连接到两个数据库（一个具有实体的主数据库，另一个具有与说的实体）。我的项目结构如下。
在我的 build.sbt 中，我有以下行
playEbeanModels in Compile := Seq("models.sentinel.*", "models.kodi.*")
在我的 application.conf 中，我有以下指向包含实体
的包
ebean.sentinel = ["models.sentinel.*"]
ebean.kodi = ["models.kodi.*"]
并这样配置数据源
db {
sentinel {
hikaricp {
dataSourceClassName = "com.mysql.jdbc.jdbc2.optional.MysqlDataSource"
maxLifetime=900000
idleTimeout=300000
maximumPoolSize=100
minimumIdle=5
username = sentinel
password = sentinelAdmin
dataSource {
user = *******
password = "*************"
databaseName = "sentinel"
serverName = "**********"
portNumber = 3306
interactiveClient=true
useUnicode=true
autoReconnect=true
prepStmtCacheSqlLimit=2048
cachePrepStmts=true
prepStmtCacheSize=250
useServerPrepStmts=true
}
}
}
kodi {
hikaricp {
dataSourceClassName = "com.mysql.jdbc.jdbc2.optional.MysqlDataSource"
maxLifetime=900000
idleTimeout=300000
maximumPoolSize=100
minimumIdle=5
username = kodi
password = kodiAdmin
dataSource {
user = ******
password = "********"
databaseName = "kodi"
serverName = "********"
portNumber = 3306
interactiveClient=true
useUnicode=true
autoReconnect=true
prepStmtCacheSqlLimit=2048
cachePrepStmts=true
prepStmtCacheSize=250
useServerPrepStmts=true
}
}
}
}
当我尝试编译并跟踪堆栈跟踪（截断以适合）时

过去一周我一直在研究这个问题，如果能深入了解可能导致此问题的原因，我将不胜感激
您的配置应如下所示：
db {
sentinel {
driver=com.mysql.jdbc.Driver
url="**********"
username=****
password="*******"
hikaricp {
...
}
}
kodi {
driver=com.mysql.jdbc.Driver
url="******"
username=****
password="****"
hikaricp {
...
}
}
}
我继续清理我的常春藤缓存。我重新运行 sbt 构建并解决了正确的依赖关系。
我在尝试启动需要能够连接到两个数据库（一个具有实体的主数据库，另一个具有与说的实体）。我的项目结构如下。 在我的 build.sbt 中，我有以下行
playEbeanModels in Compile := Seq("models.sentinel.*", "models.kodi.*")
在我的 application.conf 中，我有以下指向包含实体
的包ebean.sentinel = ["models.sentinel.*"]
ebean.kodi = ["models.kodi.*"]
并这样配置数据源
db {
sentinel {
hikaricp {
dataSourceClassName = "com.mysql.jdbc.jdbc2.optional.MysqlDataSource"
maxLifetime=900000
idleTimeout=300000
maximumPoolSize=100
minimumIdle=5
username = sentinel
password = sentinelAdmin
dataSource {
user = *******
password = "*************"
databaseName = "sentinel"
serverName = "**********"
portNumber = 3306
interactiveClient=true
useUnicode=true
autoReconnect=true
prepStmtCacheSqlLimit=2048
cachePrepStmts=true
prepStmtCacheSize=250
useServerPrepStmts=true
}
}
}
kodi {
hikaricp {
dataSourceClassName = "com.mysql.jdbc.jdbc2.optional.MysqlDataSource"
maxLifetime=900000
idleTimeout=300000
maximumPoolSize=100
minimumIdle=5
username = kodi
password = kodiAdmin
dataSource {
user = ******
password = "********"
databaseName = "kodi"
serverName = "********"
portNumber = 3306
interactiveClient=true
useUnicode=true
autoReconnect=true
prepStmtCacheSqlLimit=2048
cachePrepStmts=true
prepStmtCacheSize=250
useServerPrepStmts=true
}
}
}
}

过去一周我一直在研究这个问题，如果能深入了解可能导致此问题的原因，我将不胜感激
您的配置应如下所示：
db {
sentinel {
driver=com.mysql.jdbc.Driver
url="**********"
username=****
password="*******"
hikaricp {
...
}
}
kodi {
driver=com.mysql.jdbc.Driver
url="******"
username=****
password="****"
hikaricp {
...
}
}
}
我继续清理我的常春藤缓存。我重新运行 sbt 构建并解决了正确的依赖关系。
