关于 Invalid byte 1 of 1-byte UTF-8 sequence
不知各位有没遇到过这样的问题呢？
问题描述：像一个url请求，获取得到的参数response如下
Java code<?xml version='1.0' encoding='UTF-8'?><applyPrivilegeRet><formnum>100010</formnum><retn>-1</retn><desc>用户已经开通XXX套餐，不需要重复开通</desc><packages><opertype>1</opertype><privID>122216</privID><startdate>20120705</startdate></packages></applyPrivilegeRet>
通过以下代码解析该返回值，
Java code /** * 将xml输入流转成map对象 * @param in -- xml输入流 * @return -- map对象 */ public static Map toMap(InputStream in) { try { SAXReader reader = new SAXReader(); Document doc = reader.read(in); return toMap(doc.getRootElement()); } catch (Exception ex) { throw new RuntimeException("解析xml成map对象异常", ex); } } public static Map toMap(String xml) { ByteArrayInputStream sin = new ByteArrayInputStream(xml.getBytes()); return toMap(sin); } public MyTest(String xml){ toMap(response);}
在两台linux服务器上，一台解析是没有任何问题的，另外一台出现java.lang.RuntimeException: 解析xml成map对象异常

环境说明：两台linux服务器，用了同样的jdk，都是用jetty7。
好纠结~~~
[解决办法]
应该又是编码问题，中文读取错误了。
<?xml version='1.0' encoding='UTF-8'?>这里指定encoding是UTF-8，但实际传递的可能是GBK编码。
改成，<?xml version="1.0" encoding="GB2312"?>试一试行不行。
[解决办法]
或者
ByteArrayInputStream sin = new ByteArrayInputStream(xml.getBytes());
改成
ByteArrayInputStream sin = new ByteArrayInputStream(xml.getBytes("UTF-8"));
试试

是不是第二台机子的环境编码和程序里的编码不一样
