解析XML报错：

UTFDataFormatException: invalid byte 2 of 2-byte UTF-8 sequence (0xfa)

解决方案：

将

SAXReader reader = new SAXReader();
org.dom4j.Document document = reader.read(new ByteArrayInputStream(s.getBytes());

改成：

SAXReader reader = new SAXReader();
org.dom4j.Document document = reader.read(new ByteArrayInputStream(s.getBytes("UTF-8")));
