那个大神帮忙解决一下

Caused by: com.thoughtworks.xstream.io.StreamException: : The document type declaration for root element type "html" must end with '>'.

Caused by: org.xml.sax.SAXParseException: The document type declaration for root element type "html" must end with '>'.

检查一下配置文件或者js文件里面的某个标签的结尾应该少了一个>尖括号
