我正在使用SOAP Web服務,我需要將信息從應用程序級別(這是我的主客戶機級別)傳遞到客戶機處理程序級別以供進一步評估。我在下面列出了我的客戶端和我的客戶端處理程序。我想掃描用戶的值並存儲在處理程序中的「discountVal」變量中,以便我可以將一個文本節點添加到SOAPHeader中。將信息從應用程序傳遞到處理程序級別SOAP

任何幫助將不勝感激!我有一種感覺,使用MessageContext是一種方法,但我不確定從哪裏開始。

你說得對,使用MessageContext是一種將信息從客戶端傳遞到處理程序的方法。以下是如何做到這一點:

1)客戶端類添加

((BindingProvider)port).getRequestContext().put("discountID", discount); 

2)然後到處理器

if(context.containsKey("discountID")){ 
    discountVal = context.get("discountID"); 
} 

而這一切。
