您好正在使用注释编写一个简单的休眠程序，下面是我的 hibernate.cfg.xml 文件：

 <!DOCTYPE hibernate-configuration PUBLIC
    "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
    "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
 <session-factory>

    <!-- Database connection settings -->
    <property name="connection.driver_class">oracle.jdbc.OracleDriver</property>
    <property name="connection.url">jdbc:oracle:thin:@127.0.0.1:1521:XE</property>
    <property name="connection.username">vikas</property>
    <property name="connection.password">vikas</property>>

    <!-- JDBC connection pool (use the built-in) -->
    <property name="connection.pool_size">1</property>

    <!-- SQL dialect -->
    <property name="dialect">org.hibernate.dialect.Oracle10gDialect</property>

    <!-- Disable the second-level cache  -->
    <!-- <property name="cache.provider_class">org.hibernate.cache.internal.NoCacheProvider</property> -->

    <!-- Echo all executed SQL to stdout -->
    <property name="show_sql">true</property>

    <!-- Drop and re-create the database schema on startup -->
    <property name="hbm2ddl.auto">create</property>

    <!-- Name the annotated Entity -->
    <mapping class="org.vikas.hibernate.dto.UserDetails"></mapping>
</session-factory>

当我试图朗姆我的程序时，它会抛出以下异常：

   16:41:07.592 [main] ERROR org.hibernate.util.XMLHelper - Error parsing XML:

你能告诉我，我哪里出错了。

问题是文件中有一个错误字符或缺少字符。

例如在该行

   <property name="connection.password">vikas</property>>

最后你有一个额外的'>'。我不知道这是错误还是您删除评论时发生的错误。如果这不是错误，请查看其他错误字符。这甚至可能是一个不可见的字符（但不是一个简单的空间，它们是无害的）。</hibernate-configuration>有一次它发生在我身上，错误是标签后缺少换行符。
