Question

我遇到了麻烦，我不知道为什么我无法连接到数据库，一切都还好。

IF(LEN(MID(A1;FIND("/";A1)+1;FIND("/";A1;FIND("/";A1)+1)−FIND("/";A1)−1))=1;"0"&MID(A1;FIND("/";A1)+1;FIND("/";A1;FIND("/";A1)+1)−FIND("/";A1)−1);MID(A1;FIND("/";A1)+1;FIND("/";A1;FIND("/";A1)+1)−FIND("/";A1)−1))

我的application.conf

Answer 1

我认为可能是HikariCP模块正在寻找connectionTestQuery而没有找到它（并抛出错误）。尝试将以下内容添加到application.conf：

slick.dbs.default.db.connectionTestQuery="/*ping*/ select 1" // or whatever

回答：Caused by: java.sql.SQLException: JDBC4 Connection.isValid() method not supported

使用slickpg和playframework的SQLTimeOutException
