离线时无法解析hibernate.cfg.xml

hibernate

每当我断开互联网连接时,都会收到以下异常:

org.hibernate.HibernateException: Could not parse configuration: com/mashlife/resources/hibernate.cfg.xml
    at org.hibernate.cfg.Configuration.doConfigure(Configuration.java:1542)
    at org.hibernate.cfg.AnnotationConfiguration.doConfigure(AnnotationConfiguration.java:1035)

在我离线时发生。hibernate时,在解析配置时是否尝试读取DTD?根本原因是什么?

这是我的hibernate.cfg.xml:

<?xml version='1.0' encoding='utf-8'?>
<!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">com.mysql.jdbc.Driver</property>
        <property name="connection.url">jdbc:mysql://localhost/foo</property>
        <property name="connection.username">user</property>
        <property name="connection.password">pass</property>

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

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

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

        <!-- DO NOT Echo all executed SQL to stdout -->
        <property name="show_sql">false</property>

        <!-- Names the annotated entity class -->
        <!--<mapping class="org.hibernate.tutorial.annotations.Event"/>-->

    </session-factory>

</hibernate-configuration>

Hibernate可以在本地解析DTD(无需网络连接)。

您的DOCTYPE使用的是Hibernate 3.6
的新名称空间(http://www.hibernate.org/dtd/),因此您的类路径中可能具有较旧版本的Hibernate库。

升级到Hibernate
3.6.8.Final后,我遇到了相同的问题。我在类路径上有hibernate3.jar的多个版本,导致加载了旧的不兼容版本的DTD实体解析器,该版本仅适用于旧的命名空间(http://hibernate.sourceforge.net/)。作为参考,这是更新的DTD实体解析器的链接。

我正在使用hibernate3-maven-plugin,它对较旧版本的Hibernate具有传递依赖,因此我只需要指定对Hibernate
3.6.8.Final的插件依赖即可。

<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>hibernate3-maven-plugin</artifactId>
<version>2.2</version>
<configuration>
    ...
</configuration>
<dependencies>
    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-core</artifactId>
        <version>3.6.8.Final</version>
    </dependency>
</dependencies>
</plugin>
