1、Scala连接mysql数据库:

import java.sql.{Connection, DriverManager, PreparedStatement, ResultSet}object mysqlConn {def main(args: Array[String]): Unit = {Class.forName("com.mysql.jdbc.Driver")val conn: Connection = DriverManager.getConnection("jdbc:mysql://bash/User?useUnicode=true&characterEncoding=utf8&useSSL=false", "root", "123456")println(conn)val statement: PreparedStatement = conn.prepareStatement("select * from stuInfo")val result: ResultSet = statement.executeQuery()while (result.next()){val number: String = result.getString("stuNumber")val name: String = result.getString("stuName")val password: String = result.getString("password")println(s"学号：${number},姓名：${name},密码：${password}")}}}

2、Scala连接redis数据库:

import redis.clients.jedis.Jedisobject redisConn {def main(args: Array[String]): Unit = {//之前创建过redis集群，所以启动集群的里面的redis配置文件，就要启动整个集群//启动单独的redis就要关闭集群设置就行val jedis = new Jedis("master", 7000)jedis.set("name","少帅")val name: String = jedis.get("name")println(name)}}
