如何在 Slick-HikariCP 中设置配置参数

Question

我正在使用 Slick 和 Mysql。收到错误：

Failed to validate connection com.mysql.jdbc.JDBC4Connection@58e7cfcd (No operations allowed after connection closed.). Possibly consider using a shorter maxLifetime value."

我明白这个问题，但不知道如何在 slick on config 中设置 maxLifetime。这是我的配置：

mysqldb {
    driver = "com.mysql.cj.jdbc.Driver"
    url = "jdbc:mysql://localhost:3306"
    user = root
    password = root
    connectionTimeout = 10000
    queueSize = 50000
    minConnections = 20
    maxConnections = 40
    numThreads = 40
}

如有任何帮助，我们将不胜感激。

你可以在数据库配置下设置：

mysqldb {
    driver = "com.mysql.cj.jdbc.Driver"
    url = "jdbc:mysql://localhost:3306"
    user = root
    password = root
    connectionTimeout = 10000
    queueSize = 50000
    minConnections = 20
    maxConnections = 40
    numThreads = 40
    idleTimeout = 85000 // should be less than maxLifetime
    maxLifetime = 90000 //time is in millsecods and should be less than database wait_timeout
}
