文档根元素“持久性”，必须匹配DOCTYPE根"null“。对于persistence.xml JPA
提问于 2016-06-03 18:39:19
我收到以下错误
文档根元素“持久性”，必须与DOCTYPE根"null“匹配。
下面是导致它的XML文件。
<?xml version="1.0" encoding="UTF-8" ?>
<persistence xmlns="http://xmlns.jcp.org/xml/ns/persistence"

</persistence>Stacktrace

<?xml version="1.0" encoding="UTF-8" ?>

</persistence>但是，上面也没有说明文件必须由>关闭。它指的是</persistence>旁边的红线。

更新1-更新1
我试过这样做：
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE persistence PUBLIC
"http://xmlns.jcp.org/xml/ns/persistence"
"http://www.w3.org/2001/XMLSchema-instance"

http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd" version="2.1">错误：:org.xml.sax.SAXParseException:The public identifier must begin with either a single or double quote character.
和
<?xml version="1.0" encoding="UTF-8" ?>

您的第二个" XML“文档是一个混乱的XSD和DTD构造，最终的结果是一个根本不是XML的文档--格式不太好，更不用说有效了。
您的第一个XML文档对于通过@schemaLocation声明的XSD是有效的。错误消息是基于DTD的，而不是基于XSD的。根据@schemaLocation中暗示的XSD解析它，您就会没事了。
