  • 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"
    
    参考
