我正在尝试使用 tminglei/slick-pg v9.0.0使用光滑的 3.0.0 并且我收到了 IllegalAccessException
:

HikariCP 是 slick 3.0.0 中的默认连接池
我已经定义了驱动程序类,就像在 example 中一样。 :
trait MyPostgresDriver extends ExPostgresDriver with PgArraySupport
with PgEnumSupport
with PgRangeSupport
with PgHStoreSupport
with PgSearchSupport{
override val api = new MyAPI {}
//////
trait MyAPI extends API
with ArrayImplicits
with RangeImplicits
with HStoreImplicits
with SearchImplicits
with SearchAssistants
}
object MyPostgresDriver extends MyPostgresDriver
我的数据库配置非常简单[类型安全配置的摘录如下]:
slick.dbs.default {
driver="com.github.tminglei.MyPostgresDriver$"
db {
driver="org.postgresql.Driver"
url="jdbc:postgresql://hostname:port/dbname"
user=user
password="pass"
}
}
似乎它不应该工作,但是......
我应该以某种方式更改我的驱动程序类吗?是别的吗?
注意:从我使用的堆栈跟踪中可以看出
最后,通过 Class.class 中的 jdk 代码调试时(反编译的第 143 行)
Constructor tmpConstructor1 = this.cachedConstructor;
我得到以下(toString'ed)值(如intellij所示):
private com.github.tminglei.MyPostgresDriver$()
这能说明问题吗?如果是这样,我应该如何修复它?
编辑
我已经用股票 PostgresDriver 替换了自定义驱动程序配置,如下所示:
slick.dbs.default {
driver="slick.driver.PostgresDriver$"
db {
driver="org.postgresql.Driver"
url="jdbc:postgresql://hostname:port/dbname"
user=user
password="pass"
}
}
错误是一样的:
akka.actor.ActorInitializationException: exception during creation
...
Caused by: java.lang.RuntimeException: driverClassName specified class 'slick.driver.PostgresDriver$' could not be loaded
...
Caused by: java.lang.IllegalAccessException: Class com.zaxxer.hikari.AbstractHikariConfig can not access a member of class slick.driver.PostgresDriver$ with modifiers "private"
最佳答案
我有一个类似的问题。
我认为您正在使用 Database.forConfig("slick.dbs.default")
但你的配置文件在 DatabaseConfig格式。
相反,请尝试使用:
val dbConfig: DatabaseConfig[PostgresDriver] = DatabaseConfig.forConfig("slick.dbs.default")
val db = dbConfig.db
关于scala - 未加载 HikariCP 驱动程序的 3.0.0 - IllegalAccessException : AbstractHikariConfig can not access a member with modifiers "private",我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/31155042/
