XML 配置文件注释引起错误及解决方案

在配置war/src/webroot/META-INF/autoconf/news-resource.xml.vm时，在xml文件中有中文的注释。重新编译后启动时，产生下列的异常

从错误描述来看发现是ＸＭＬ文件中的注释引起的异常，去掉配置文件中的中文注释或改用英文描述则可以通过
后来发现是配置文件中采用：

单数个中文或字母后跟单数个中文再用“-->”结束注释（中文后不加空格） 
如：<!-- 单数个中文-->、<!-- a单数个中文--> 

时就会报此异常
争对此异常可以采用在左右边界加上空格的方式解决。
在Eclipse中开发时不太容易出现此异常，因为Eclipse的XML　格式化功能会自动在书写时加上空格，但如果用netbeans
开发时则要注意此项自己手动加上空格。
