【问题描述】：

我正在尝试找出我的持久性文件中的一个错误，我需要您的专家指导来帮助我解决这个问题。持久性文件如下所示：

<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_1.xsd" version="2.1">
    <persistence-unit name="ArchiveTicket">
        <provider>org.hibernate.ejb.HibernatePersistence</provider>
        <non-jta-data-source>jdbc/archiveDbDatasource</non-jta-data-source>

        <class>blah blah</class>
        <class>blah blah</class>
        <class>blah blah</class>
        <class>blah blah</class>
        <class>blah blah</class>
        <class>blah blah</class>
        <class>blah blah</class>
        <properties>
            <property name="hibernate.query.factory_class" value="org.hibernate.hql.classic.ClassicQueryTranslatorFactory"/>
        </properties>
    </persistence-unit>
</persistence>

错误是：

org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 7 in XML document from class path resource [archive-ticket-persistence.xml] is invalid; nested exception is org.xml.sax.SAXParseException; systemId: http://www.oracle.com/technetwork/java/index.html; lineNumber: 7; columnNumber: 41; s4s-elt-character: Non-whitespace characters are not allowed in schema elements other than 'xs:appinfo' and 'xs:documentation'.

我尝试更改版本，但都是徒劳的。我不确定这里有什么问题。任何有关解决此问题的建议都会有所帮助。谢谢

【参考方案1】：

我认为这里发生的情况是http://java.sun.com/xml/ns/persistence/persistence_2_1.xsd 位置没有架构，当 XML 解析器去这个位置寻找架构时，它会被重定向到 Oracle 网站上的 HTML 页面，该页面无法被解析为模式；架构处理器在读取 HTML 页面上的一些随机 javascript 时检测到错误，因此报告完全无用的错误消息。

这里似乎给出了正确的架构位置：How to specify JPA 2.1 in persistence.xml?

【讨论】：

从提供的链接添加 xmlns 后出现新错误 - Configuration problem: Unable to locate Spring NamespaceHandler for XML schema namespace [http://xmlns.jcp.org/xml/ns/persistence] Offending resource: class path resource [archive-ticket-persistence.xml]

恐怕帮不了你。
