scala连接数据库

scala连接数据库

使用JDBC即可:

  • 在sbt中添加对应依赖
libraryDependencies ++= Seq(
  "mysql" % "mysql-connector-java" % "5.1.33"
)
  • 在代码中引用
import java.sql.{Connection, DriverManager}

    def insertMysql(date: String, dbDriver: String, dbAdd: String, dbTable: String, dbUser: String, dbPasswd: String, hostApk: String, aid: Long): Unit = {
      var connection:Connection = null
      try{
        Class.forName(dbDriver)
        connection = DriverManager.getConnection(dbAdd, dbUser, dbPasswd)
        val statement = connection.createStatement()

        val delSql = "delete from " + dbTable + " where dt=" + date.toInt + " and hostapk=" + """"""" + hostApk + """""""
        val insertSql = "insert into " + dbTable + "(dt, hostapk, aid)" + " values(" + date.toInt + "," + """"""" + hostApk + """"""" + "," + aid + ")"

        println("print the SQL statement:")
        println(delSql)
        println(insertSql)

        statement.execute(delSql)
        statement.execute(insertSql)
      }catch {
        case e: Exception => e.printStackTrace()
      }
      connection.close()
    }
  • 对应的参数如下:
dbDriver="com.mysql.jdbc.Driver"
dbAddr="jdbc:mysql://127.0.0.1/data"
dbTable="hah"
dbUser="hi"
dbPasswd="nihao"
