在.jar中发布xml而在eclpise中发布时，会出现“1字节UTF-8序列的无效字节1”

标签： java xml eclipse encoding utf-8

我有一个问题，我正在努力，我读了很多关于＆＃34; 1字节UTF-8序列的无效字节1＆＃34; ， 如 XML Invalid byte 1 of 1-byte UTF-8 sequence ， MalformedByteSequenceException Invalid byte 1 of 1-byte UTF-8 sequence。但它并没有解决我的问题。

我有一个Web应用程序（生活在paas云中），它可以正常处理来自移动客户端的请求（不是我自己开发的）。

为了测试服务器应用程序，我编写了一个基于Swing的客户端应用程序（比如test-client），通过HTTP将xml数据发布到我的服务器上。

奇怪的问题是，当我在eclipse中运行这个测试客户端时，它可以正常提交帖子并从我的服务器上获取消息。

但是当我将它导出到Runnable jar时，在我的服务器日志中发现异常＆＃34; org.dom4j.DocumentException: Invalid byte 1 of 1-byte UTF-8 sequence. Nested exception: Invalid byte 1 of 1-byte UTF-8 sequence.＆＃34;当我发布一些包含中文字符的xml数据时。

我相信这与我的电脑和日食之间的差异编码有关。

请注意

1.我没有要读取的xml，而是从对象

构造xml数据

2.my general / preference / workspace被编码为UTF-8。我的doPost中有request.setCharacterEncoding("UTF-8");;

3.我希望修改我的测试客户端代码以使其正常工作，因为服务器现在可以与移动用户一起正常生产。

以下是我发布xml数据的方法

        URL url = new URL(address);
        URLConnection uc = url.openConnection();
        HttpURLConnection conn = (HttpURLConnection) uc;
        conn.setDoInput(true);
        conn.setDoOutput(true);
        conn.setRequestMethod("POST");
        conn.setRequestProperty("Content-type", "text/xml");
        System.out.println("before POST:\n"+xmlstr);
        PrintWriter pw = new PrintWriter(conn.getOutputStream());
        pw.write(xmlstr);
        pw.close();

xmlstr来自下面

（RequestTextMessage是一个非常简单的类，只有getter，这个Class的一个字段将接受一个输入字符串，可能是中文）：

 xmlStr= XMLRequest.textMessageToXml(msg);

public static String textMessageToXml(RequestTextMessage textMsg){
    xstream.alias("xml", textMsg.getClass());
    return xstream.toXML(textMsg);
}
   private static XStream xstream = new XStream(new XppDriver() {

        @Override
        public HierarchicalStreamWriter createWriter(Writer out) {  
            return new PrettyPrintWriter(out) {  
                boolean cdata = true;  

                protected void writeText(QuickWriter writer, String text) {  
                    if (cdata) {  
                        writer.write("<![CDATA[");  
                        writer.write(text);  
                        writer.write("]]>");  
                    } else {  
                        writer.write(text);  
                    }  
                }  
            };  
        }  
    });

答案 0 :(得分：3)

您需要选择PrintWriter使用的编码。在Eclipse之外，您的平台可能默认为UTF-8以外的其他东西。

试试这段代码：

PrintWriter pw = new PrintWriter(new OutputStreamWriter(
    conn.getOutputStream(), "UTF-8"));
