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"
