jruby jdbc连接oracle

jruby jdbc连接oracle

require 'java'

import 'oracle.jdbc.driver.OracleDriver'

module JavaLang

  include_package "java.lang"

end

module JavaSql

  include_package "java.sql"

end

#JavaLang::Class.forName("oracle.jdbc.driver.OracleDriver").newInstance

##发现如果直接用Class.forName话根本找不到类。看来jruby是预先导入的直接用import CLASS即可

con =

  JavaSql::DriverManager.getConnection( \

    "jdbc:oracle:thin:@132.228.129.104:1521:ods","ods","ods")

  sql = con.createStatement()

  result = sql.executeQuery("select * from dual")

  while result.next

    puts result.getString(1)

  end
