本篇介绍如果设置使用Slick的Scala开发环境,这里我们使用SBT命令行,SBT使用的目录结构和Maven一样,我们可以创建一个目录,比如Slick,然后创建如下的缺省目录结构:
src
main
java
resources
scala
test
java
resources
scala
因为我们打算使用MySQL数据库,并使用Slick来访问数据库,因此我们在Slick的根目录下创建一个build.sbt,添加相关引用:
name := "Scala Slick Examples" version := "1.0" scalaVersion := "2.10.4" libraryDependencies += "com.typesafe.slick" %% "slick" % "2.0.2" libraryDependencies += "org.slf4j" % "slf4j-nop" % "1.6.4" libraryDependencies += "mysql" % "mysql-connector-java" % "5.1.18"
Slick使用SLF4J 作为日志库文件。
我们的MySQL数据库 Chinook 安装在本地服务器上面,我们在使用Slick可以手工创建数据库表Schema的定义,也可以使用自动代码生成工具从已有的数据库创建Table的Schema定义。
我们在命令行输入 sbt ,进入SBT控制台。
然后我们使用console,进入Scala控制台,注意此时SBT自动把build.sbt中引用到的库比如slick, mysql添加到Scala控制台,我们使用如下命令:
scala.slick.model.codegen.SourceCodeGenerator.main( Array(slickDriver, jdbcDriver, url, outputFolder, pkg, user, password) )
相关参数如下:
slickDriver Fully qualified name of Slick driver class, e.g. “scala.slick.driver.H2Driver”
jdbcDriver Fully qualified name of jdbc driver class, e.g. “org.h2.Driver”
url jdbc url, e.g. “jdbc:postgresql://localhost/test”
outputFolder Place where the package folder structure should be put
pkg Scala package the generated code should be places in
user database connection user name
password database connection password
例如对于,我们使用mysql数据库,可以在命令行输入如下命令:注意修改你的用户名和密码:
scala.slick.model.codegen.SourceCodeGenerator.main(
Array("scala.slick.driver.MySQLDriver", "com.mysql.jdbc.Driver",
"jdbc:mysql://127.0.0.1/Chinook",
"./src/main/scala",
"com.guidebee.slick.example", "user", "password")
)
这样自动代码生成工具,就在/src/main/scala目录下生成了Tables.scala文件
package com.guidebee.slick.example
