我可以在Java SDK 0.9.0中爲Azure服務總線連接設置代理嗎？

Question

我正在與第三方進行整合，第三方爲我們提供了Azure服務總線隊列以接收消息。 （我們使用的0.9.0 Azure的罐子從下載鏈接https://azure.microsoft.com/en-us/documentation/articles/java-download-azure-sdk/）

我成立了像這樣的連接：

Configuration config = new Configuration(); 
config = ServiceBusConfiguration.configureWithConnectionString(null, config, connectionString); 
ServiceBusContract azureService = ServiceBusService.create(config); 

和接收消息，像這樣：

ReceiveQueueMessageResult resultQM = azureService.receiveQueueMessage(queueName, receiveMessageOptions); 

這在正常情況下工作正常。然而，在辦公室，我必須去通過代理，並且連接失敗，此錯誤：

現在，當我看documentation爲com.microsoft.windowsazure.Configuration，它顯示常量兩個屬性：

• PROPERTY_HTTP_PROXY_HOST（字符串值 「http.proxyHost」）
• PROPERTY_HTTP_PROXY_PORT（字符串值 「把http.proxyPort」）

但是，這些常量似乎不存在於0.9.0中。我已經嘗試使用字符串文字向配置添加屬性，但是這並沒有明顯的效果。

我是否在正確的軌道上？有沒有辦法在0.9.0中設置服務總線合同的代理？

根據類別Configuration的源代碼，將屬性PROPERTY_HTTP_PROXY_HOST & PROPERTY_HTTP_PROXY_PORT定義爲靜態最終變量。所以你不能通過方法setProperty來改變它們的值。

據我所知，支持Java代理的方法有兩種，可以在當前場景中使用。

1. 命令行JVM設置：代理設置經由命令行參數提供給JVM：

   的java -Dhttp.proxyHost = proxyhostURL -Dhttp.proxyPort = proxyPortNumber -Dhttp.proxyUser = someUserName -Dhttp .proxyPassword = somePassword

2. 在代碼中設置系統屬性在Java代碼中添加以下行，以便JVM使用代理進行HTTP調用。這當然會要求你重新編譯你的Java源代碼。 （其他方法不需要任何重新編譯）：

   System.setProperty（「http.proxyPort」，「someProxyPort」）; System.setProperty（「http.proxyUser」，「someUserName」）; System.setProperty（「http.proxyPassword」，「somePassword」）; System.setProperty（「http。ProxyHost的」， 「someProxyURL」）;
