如何防止在JDeveloper中使用Web服務代理類時轉換爲<

Question

我正在調用發送HTML電子郵件的BPM Web服務。我在JDeveloper 11.1.1.7中生成了一個Web服務代理。電子郵件正文的類型是xsd：string，它應該映射到java String。我知道某些字符（例如<> &）在代理操作期間在xml文檔創建期間被保留和轉換。

使用SOAPUI來調用服務，我可以傳遞正文<h1>My Heading</h1>和服務正確響應，發送電子郵件與預期的HTML。當從調用代理的POJO執行相同操作時，<h1>轉換爲<h1>My heading</h1>。

我試過將身體作爲CDATA部分傳遞，但這並沒有什麼區別。我曾嘗試將該體轉換爲字節，然後在調用之前返回到UTF-8字符串，但仍然沒有區別。我有權訪問BPM服務代碼。有沒有一種方法可以將HTML從代理髮送到服務，並保留特殊字符？

我終於明白了這一點。雖然JDeveloper Web服務代理生成器在大多數情況下都很有用，但在這種情況下，並不是因爲我需要將xml特殊字符發送到服務。也許有辦法操縱代理代碼來做你想做的事情，但我無法弄清楚。

特別的幫助是this AMIS blog entry。如果您在JAXB編組過程中需要處理特殊字符，this entry will help you too。 steps to use the java URLConnection class is here的一個偉大的總結，並回答points to a library that would probably make life even easier。

所以這裏是下面的原始包裝代碼。我們編寫的特定BPM電子郵件服務也寫入日誌，並解釋了原始xml輸入中的複雜類型。當然，我會從主sendMail包裝方法中傳入的POJO對象中填充電子郵件的值。
