我是熟悉hibernate的新手，并且很难理解错误是什么。用于休眠的jar文件是

hibernate-annotations.jar
hibernate-jpa-2.0-api-1.0.1.Final.jar
hibernate3.jar

我的hibernate.cfg.xml文件为

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration SYSTEM
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
 <hibernate-configuration>
    <session-factory>   


        <property name="connection.driver_class">com.mysql.jdbc.Driver</property>

Answer 1

我认为您在正确连接数据库时遇到问题。您确定用户名和密码是否正确？或者您是否已经拥有一个名为datacenter的数据库？

同时尝试将文档类型更改为

<!DOCTYPE hibernate-configuration PUBLIC
          "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
          "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

Answer 2

请参阅Can't parse hibernate.cfg.xml while offline

根据您的休眠版本，hibernate可能会尝试从互联网加载DTD，同时重置连接。

Answer 3

运行hibernate应用程序离线使用'hibernate-core jar'文件它会工作.. 无需更改您的Hibernate配置文件.Avvappa，BEL。

Answer 4

按如下方式更改您的Hibernate配置;

<hibernate-configuration
        xmlns="http://www.hibernate.org/xsd/hibernate-configuration"
        xsi:schemaLocation="http://www.hibernate.org/xsd/hibernate-configuration hibernate-configuration-4.0.xsd"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

----------------------------to as below -------------------------------------

<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD 3.5//EN"
        "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>

Answer 5

改变你的hiber配置，即

<hibernate-configuration
    xmlns="http://www.hibernate.org/xsd/hibernate-configuration"
    xsi:schemaLocation="http://www.hibernate.org/xsd/hibernate-configuration hibernate-configuration-4.0.xsd"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

----------------------------如下---------------- ---------------------

<!DOCTYPE hibernate-configuration PUBLIC
    "-//Hibernate/Hibernate Configuration DTD 3.5//EN"
    "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

Answer 6

尝试在系统连接到Internet时运行程序

我遇到了同样的问题。当我在网上搜索解决方案时发现这个线程有关同一问题。

我回去尝试再次运行该程序并且工作正常，所做的唯一更改是连接到Internet连接。我关闭了连接，程序再次给出了同样的错误。

我的猜测是Hibernate配置文件正在从互联网上下载DTD，当它无法这样做时，它会在创建SessionFactory对象时出错。

    <!DOCTYPE hibernate-configuration PUBLIC  
      "-//Hibernate/Hibernate Configuration DTD 3.0//EN"  
      "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

Answer 7

如果未解析配置文件，只需检查hibernate版本。如果是休眠3，则DTD应来自 Sourceforge 网站。如果它是更高版本的DTD应该是

<!DOCTYPE hibernate-configuration SYSTEM  
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
