在我的Java项目中，我通过http://x-stream.github.io/解析传入的xml
这是我的代码：
try {
Account account = (Account) xstream.fromXML(oneM2DocumentAsString);
} catch (StreamException ex) {
logger.error("Error message " + ex.getMessage(), ex);
}
在xml中使用符号“＆”时，出现错误：
[java] [26.08.2018 14:49:05.641] myproject.M2XMLParser.parseOne(M2XMLParser.java:229) ERROR:

但是我需要知道：
