ActiveRecord拒绝更改端口

Question

使用以下代码：

require 'activerecord-jdbc-adapter'
require 'activerecord-jdbcmssql-adapter'
require_relative 'sqljdbc42.jar'

ActiveRecord::Base.establish_connection(
                      :adapter => 'jdbcmssql',
                      :driver => 'com.microsoft.sqlserver.jdbc.SQLServerDriver',
                      :username => 'pcp_admin',
                      :password => 'pcp_admin01',
                      :port => 1021,
                      :database => 'pcp',
                      :url => 'jdbc:sqlserver://OHNALWBD0145.nwie.net',
)
@connection = ActiveRecord::Base.connection

这是要使用的所有正确信息。但是，当我尝试运行它时，我收到以下错误：

ActiveRecord::JDBCError: com.microsoft.sqlserver.jdbc.SQLServerException: The TCP/IP connection to the host OHNALWBD0145.nwie.net, port 1433 has failed. Error: "Connection refused: no further information. Verify the connection properties. Make sure that an instance of SQL Server is running on the host and accepting TCP/IP connections at the port. Make sure that TCP connections to the port are not blocked by a firewall.".

我发现此错误消息特别奇怪，因为我已将端口输入方法1021，而不是1433.我不知道为什么它尝试使用端口1433.我知道这是默认端口SQLServer，但我应该重写，或者我认为。
