我能做些什么"无法解析配置"来自Hibernate的错误？ [英] What can I do with "Could not parse configuration" error from Hibernate?

问题描述

我遵循YouTube的 Java Hibernate教程。在我尝试运行应该在Apache Derby服务器上创建表Employee的代码之前，一切看起来都很棒。我试图先使用SQL服务器（2008），并得到相同的错误。
无法解析配置：hibernate.cfg.xml ，并且还存在超时错误。我感谢任何帮助。感谢。

以下是我得到的错误：

 这是我的hibernate.cfg.xml文件： 
 <？xml version ='1.0'encoding ='utf-8'？>

 以下是我正在运行的代码： 
  package com.hibernate.chapter1; 
 import org.hibernate.cfg.AnnotationConfiguration; 
 import org.hibernate.tool.hbm2ddl.SchemaExport; 
 public class TestEmployee {
 public static void main（String [] args）{
 AnnotationConfiguration config = new AnnotationConfiguration（）; 
 config.addAnnotatedClass（Employee.class）; 
 config.configure（hibernate.cfg.xml）; 
 
新建SchemaExport（config）.create（true，true）; 
 
 
 $ / code> 
我做错了什么？
解决方案
这意味着hibernate.dtd无法解析 - 它的解析是在服务器上尝试的。 dtd包含在jar文件中 - 请参阅此处和< a href =http://forum.springsource.org/showthread.php?80886-How-to-configure-hibernate.cfg.xml-to-work-offline =noreferrer> here  for如何解决它。
 
I am following Java Hibernate tutorial example from YouTube. Everything looks great until I try to run code which is supposed to create table Employee on Apache Derby server. I tried to use SQL server (2008) first and I was getting the same error.
Could not parse configuration: hibernate.cfg.xml and there is also timeout error. I appreciate any help. Thanks.

Here is the error I get:

Here is my hibernate.cfg.xml file:
<?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">org.apache.derby.jdbc.ClientDriver</property>
        <property name="connection.url">jdbc:derby://localhost:1527/HibernateDb;create=true</property>
        <property name="connection.username">user</property>
        <property name="connection.password">password</property>

        <!-- JDBC connection pool (use the built-in) -->
        <property name="connection.pool_size">2</property>

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

        <!-- Enable Hibernate's current session context -->
        <property name="current_session_context_class">thread</property>

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

    </session-factory>

</hibernate-configuration>
And, here is the code I am running:
package com.hibernate.chapter1;   
import org.hibernate.cfg.AnnotationConfiguration;
import org.hibernate.tool.hbm2ddl.SchemaExport;
public class TestEmployee {
    public static void main(String[] args) {
        AnnotationConfiguration config = new AnnotationConfiguration();
        config.addAnnotatedClass(Employee.class);
        config.configure("hibernate.cfg.xml");

        new SchemaExport(config).create(true, true);
    }    
}
What did I do wrong?
解决方案
This means the hibernate.dtd cannot be resolved - its resolution is attempted on the server. The dtd is contained in the jars files - see here and here for how to resolve it.
