仅限 当我离线时发生。在解析配置时，hibernate是否尝试读取DTD？这里的根本原因是什么？

这是我的hibernate.cfg.xml：

 <？xml version ='1.0'encoding ='utf-8'？> 
<！DOCTYPE hibernate-configuration PUBLIC 
 -  // Hibernate / Hibernate配置DTD 3.0 // EN
http://www.hibernate.org/dtd/hibernate-configuration -3.0.dtd> 
 
< hibernate-configuration> 
 
< session-factory>

解决方案

Hibernate可以本地解析DTD（无需网络连接）。

您的DOCTYPE正在使用新的命名空间（ http ：//www.hibernate.org/dtd/ ），因此您的类路径中可能会包含旧版Hibernate库。

升级到Hibernate 3.6.8.Final后，我遇到了同样的问题。我在类路径中有多个hibernate3.jar版本，导致旧版本的 DTD Entity Resolver 将被加载，它只适用于旧的命名空间（ http://hibernate.sourceforge.net/ ）。作为参考，这里是一个链接到新的 DTD Entity Resolver 。

我使用hibernate3-maven-plugin，它对旧版本的Hibernate所以我只需要在Hibernate 3.6.8.Final中指定一个插件依赖项。

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

Whenever I'm disconnected from the internet, I get the following exception:

org.hibernate.HibernateException: Could not parse configuration: com/mashlife/resources/hibernate.cfg.xml

This only happens when I'm offline. Does hibernate try to read the DTD when parsing the config? What's the root cause here?

Here is my 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>

解决方案

Hibernate can resolve the DTDs locally (without a network connection).

Your DOCTYPE is using the new namespace (http://www.hibernate.org/dtd/) for Hibernate 3.6, so you might have an older version of the Hibernate libraries in your classpath.

I experienced the same issue after upgrading to Hibernate 3.6.8.Final. I had multiple versions of hibernate3.jar on the classpath causing an old incompatible version of the DTD Entity Resolver to be loaded which only works with the old namespace (http://hibernate.sourceforge.net/). For reference, here's a link to the newer DTD Entity Resolver.

I'm using hibernate3-maven-plugin which has a transitive dependency on an older version of Hibernate so I just had to specify a plugin dependency on Hibernate 3.6.8.Final.

<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>
