在用XStream將xml
還原序列化 為Javabean時報錯，資訊如下：

   產生的原因：
簡單的說就是XML檔案的編碼和解析XML時用的編碼不一致產生的問題。

       由於檔案會以系統的預設編碼對檔案進行儲存，在中文版的window下Java的預設的編碼為GBK，所以預設產生的xml檔案是以GBK格式來儲存的，所以我們使用GBK、GB2312編碼來產生xml檔案能正確的被解析，而以UTF-8格式產生的檔案不能被xml解析器所解析的原因，其實和之前文章碰到的問題類似：http://sjsky.iteye.com/blog/1053931

 

 
解決辦法 ：

 

    就是為DOM解析器指定好編碼utf-8，代碼如下

1.XStream xStream = new XStream(new DomDriver("utf-8"));
