"Invalid byte 1 of 1-byte UTF-8 sequence" occurs when posting xml in .jar but not in eclpise
提问by Jaskey
I have a problem where I am struggling, and I read many thread about "Invalid byte 1 of 1-byte UTF-8 sequence" , such as XML Invalid byte 1 of 1-byte UTF-8 sequence, MalformedByteSequenceException Invalid byte 1 of 1-byte UTF-8 sequence. But it does not solve my problem.
我在苦苦挣扎的地方遇到了一个问题，我阅读了许多关于“1 字节 UTF-8 序列的无效字节 1”的线程，例如 XML 无效字节 1 的 1 字节 UTF-8 序列， MalformedByteSequenceException Invalid byte 1 of 1 -byte UTF-8 序列。但这并不能解决我的问题。
I have a web application(living in a paas cloud), and it is working fine to handle the request from the mobile clients(not developed by myself).
我有一个 Web 应用程序（位于 paas 云中），它可以很好地处理来自移动客户端的请求（不是我自己开发的）。
In order to test the server application, I write a client application(say test-client)based on Swing to post the xml data through HTTP to my server.
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。
The strange problem is that when I run this test-client in eclipse , it works fine to submit the post and get the message from my server back.
奇怪的问题是，当我在 eclipse 中运行这个测试客户端时，提交帖子并从我的服务器取回消息可以正常工作。
But when I export it into Runnable jar, the exception is found in my server logs that " org.dom4j.DocumentException: Invalid byte 1 of 1-byte UTF-8 sequence. Nested exception: Invalid byte 1 of 1-byte UTF-8 sequence." when I post some xml data contains Chinese Character.
但是当我将它导出到Runnable jar时，org.dom4j.DocumentException: Invalid byte 1 of 1-byte UTF-8 sequence. Nested exception: Invalid byte 1 of 1-byte UTF-8 sequence.在我发布一些包含汉字的xml数据时，在我的服务器日志中发现“ ”异常。
I believe this is relative to the difference encoding between my computer and eclipse.
我相信这与我的计算机和 eclipse 之间的差异编码有关。
Please note that
请注意
1.I do not have xml to read,instead I construct the xml data from an object
1.我没有要读取的xml，而是从对象构造xml数据
2.my general/preference/workspace is encoded as UTF-8. And I have request.setCharacterEncoding("UTF-8");in my doPost;
2.我的general/preference/workspace 被编码为UTF-8。我request.setCharacterEncoding("UTF-8");在我的 doPost 中；
3.I hope to modify my test-client code to let it works fine since the server is now working fine in production with the mobile user.
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在生产中正常工作。
Below is how I post the xml data
以下是我发布 xml 数据的方式
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();
And the xmlstr comes from below
而 xmlstr 来自下面
(RequestTextMessage is a very easy class which only has getter, and one field of this Class will accept a input String, which may be Chinese):
（RequestTextMessage是一个很简单的类，只有getter，这个Class的一个字段会接受一个输入String，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);
}
}
};
}
});
For your information the exception from the server is below(I am sorry the exception is reverse):
供您参考，来自服务器的异常如下（很抱歉，异常是相反的）：

You need to choose the encoding used by your PrintWriter. Outside of Eclipse, your platform is presumably defaulting to something other than UTF-8.
您需要选择您的PrintWriter. 在 Eclipse 之外，您的平台可能默认为 UTF-8 以外的其他格式。
Try this code:
试试这个代码：
PrintWriter pw = new PrintWriter(new OutputStreamWriter(
conn.getOutputStream(), "UTF-8"));
