我正在使用此网站上提供的课程:https://www.oracle.com/technetwork/articles/dsl/jruby-oracle11g-330825.html

我正在设置SSL,我需要将java.util.properties列表传递给驱动程序管理器。

我认为我做这样的事...

# jdbc_connection.rb

require 'java'

java_import 'oracle.jdbc.OracleDriver'
java_import 'java.sql.DriverManager'
java_import 'java.util.Properties' #<---Import here

class OracleConnection

  @conn = nil

  def initialize (url)
    @url = url
    #I want to create the array of properties here and populate it with my SSL properties. I'm really lost here.

    # Load driver class
    oradriver = OracleDriver.new

    DriverManager.registerDriver oradriver
    #I want to pass the Properties to DriverManager.
    @conn = DriverManager.get_connection url, properties 
    @conn.auto_commit = false

  end

我想知道如何在ruby中创建属性并传递它们。有什么想法吗?

像Ruby一样处理java.util.Properties Java类(所有API方法都可用)

如果您查看文档Properties extends Hashtable,并且HashtableMap(实现),也是

JRuby为所有地图类型提供了扩展,使其非常像Ruby Hash

properties = java.util.Properties.new
properties.put 'a.ssl.key', 'A-VALUE' # Java style (put inherited from Hashtable)
properties['another.ssl.key'] = 'ANOTHER' # Ruby Hash style
