Question

您正在使用anotation编写一个简单的hibernate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>

当我试图朗读我的程序时，它会引发异常：

请你告诉我，我哪里出错了。

Answer 1

问题是文件中有一个错误的字符或缺少字符。

例如在行

中

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

你有一个额外的'＆gt;'在末尾。我不知道这是错误还是在您删除评论时发生的错误。如果这不是错误，那么请查看其他错误字符。这甚至可能是一个看不见的角色（但不是一个简单的空间，它们是无害的）。有一次它发生在我身上，错误是</hibernate-configuration>标记后缺少换行符。
