scala-jdbc-scalike操作jdbc數據庫

1, 引入maven依賴

 <!-- 使用 sclaikeJDBC -->
        <dependency>
            <groupId>org.scalikejdbc</groupId>
            <artifactId>scalikejdbc_2.11</artifactId>
            <version>3.3.1</version>
        </dependency>
        <dependency>
            <groupId>org.scalikejdbc</groupId>
            <artifactId>scalikejdbc-core_2.11</artifactId>
            <version>3.3.1</version>
        </dependency>
        <dependency>
            <groupId>org.scalikejdbc</groupId>
            <artifactId>scalikejdbc-config_2.11</artifactId>
            <version>3.3.1</version>
        </dependency>

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>5.1.45</version>
</dependency>

2, 在resource下使用配置文件 

application.conf

// 使用 scalike
db.pvuv.driver="com.mysql.jdbc.Driver"
db.pvuv.url="jdbc:mysql://10.110.123.84:3306/spark?characterEncoding=utf-8"
db.pvuv.user="wenbronk"
db.pvuv.password="a75767626"

3, 使用scalike進行讀取或者插入操作

import scalikejdbc._
import scalikejdbc.config.{DBs, DBsWithEnv}

object ScalikeJDBCTests {

  def main(args: Array[String]): Unit = {
    DBs.setup('pvuv)
//    DBs.setupAll()
//    DBsWithEnv("prod").setup('pvuv)
    NamedDB('pvuv) readOnly(implicit session => {
      sql"select * from host_dict".map(_.long(1)).list().apply()
    })
  }

}

 

也可以對環境進行區分

development.db.default.driver="org.h2.Driver"
development.db.default.url="jdbc:h2:file:./db/default"
development.db.default.user="sa"
development.db.default.password=""

prod {
  db {
    sandbox {
      driver="org.h2.Driver"
      url="jdbc:h2:file:./are-you-sure-in-production"
      user="user"
      password="pass"
    }
  }
}

配置文件的加載方式為: 

DBsWithEnv("development").setupAll()
DBsWithEnv("prod").setup('sandbox)
