对于 SqlServer，请通过 DatabaseConfig.setDatabasePlatformName 明确选择 sqlserver16 或 sqlserver17 作为平台
For SqlServer please explicitly choose either sqlserver16 or sqlserver17 as the platform via DatabaseConfig.setDatabasePlatformName
我正在使用 sbt 1.6.2 和 Scala 2.13.8 开发 Java Play Framework 模板 2.8.13，我从 2.1.5 升级到上述版本。问题是当我尝试连接到 SQL 服务器时（SQL Server Management Studio v18.4，服务器版本为 14.0.1000.169）
我的application.conf:
play.db {
config = "db"
default = "default"
prototype {
# Sets a fixed JDBC connection pool size of 50
hikaricp.minimumIdle = 5
hikaricp.maximumPoolSize = 5
}
}
db {
default.hikaricp.connectionTestQuery="SELECT 1"
default.driver=net.sourceforge.jtds.jdbc.Driver
default.url="jdbc:jtds:sqlserver://127.0.0.1:1433/dbName"
default.username="sa"
default.password="test12"
default.databasePlatformName="sqlserver17"
default.logstatements=true
}
ebean.default = ["models.*"]

我的Global.java

我已经试过了
- 验证与 SQL 的连接 > OK
- 新 driver 喜欢：
db.default.driver=com.microsoft.sqlserver.jdbc.SQLServerDriver
db.default.url="jdbc:sqlserver://localhost\MSSQLSERVER:1433;databaseName=dbName"
db.default.username=sa
db.default.password="test12"
db.default.logSql=true
db.default.hikaricp.connectionTestQuery="SELECT 1"
和变体。最后一个是 运行 一个旧版本的 play 2.1.5
项目
现在不知道如何连接。
那么，也许有人有 SQL 服务器的示例 application.conf？
