尝试在我的应用程序中使用Hibernate
时出现以下错误:
org.hibernate.HibernateException: Could not parse configuration: hibernate.cfg.xml
造成这种情况的原因是什么?请参阅下面的hibernate.cfg.xml
,output
和Runner class
?
注意:我查看了this answer并尝试使用建议进行修复,但没有运气。
hibernate.cfg.xml中:
<?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:3306/test-db</property>
<property name="connection.username">user</property>
<property name="connection.password">password</property>
<!-- SQL dialect -->

<!-- Use XML-based mapping metadata -->
<!-- <mapping resource="domain/Message.hbm.xml"/> -->
<!-- Use Annotation-based mapping metadata -->
<mapping class="entity.Message"/>
</session-factory>
</hibernate-configuration>
输出:

这是因为您的互联网阻止从该DTD获取数据。 只需下载所有在xml文件中提及的DTD,并在所有xml文件中提供这样的位置。 这对我有用
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "C:\Downloads\hibernate-mapping-3.0.dtd"> <hibernate-configuration>

为了解析为xml,你的hibernate.cfg.xml应该以:
开头<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
检查hibernate.cfg.xml中的以下内容:
<?xml ?>
<?xml ?>
定义<?xml ?>

您可以尝试使用以下配置详细信息,并确保已将 hibernate.cfg.xml 文件放在SRC目录下。如果必须放置除SRC之外的cfg文件,则必须在创建SessionFactory时在Configuration()中指定路径。
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<property name="hibernate.connection.driver_class"> com.mysql.jdbc.Driver </property>
<property name="hibernate.connection.url"> jdbc:mysql://localhost:3306/hibernatex </property>
<property name="hibernate.connection.username"> root </property>
<property name="hibernate.connection.password"> root </property>
<property name="hibernate.dialect"> org.hibernate.dialect.MySQLDialect </property>
<mapping resource="com/ora/hibernate/examples/Employee.hbm.xml"
package="com.ora.hibernate.examples" />
</session-factory>
</hibernate-configuration>

我遇到了同样的问题,所以我刚刚下载了配置文件中提到的文件并将其放在'/home/ist/Downloads/hibernate-configuration-3.0.dtd'的路径中,并将该路径提供给配置文件,它工作。希望它对你也有帮助。
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"/home/ist/Downloads/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<!-- JDBC Database connection settings -->
<property name="connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="connection.url">jdbc:mysql://localhost:3306/HibernateDB</property>
<property name="connection.username">root</property>
<property name="connection.password">root</property>
<!-- JDBC connection pool settings ... using built-in test pool -->
<property name="connection.pool_size">10</property>
<!-- Select our SQL dialect -->
<property name="dialect">org.hibernate.dialect.MySQLDialect</property>
<!-- Echo the SQL to stdout -->
<property name="show_sql">true</property>
<property name="format_sql">true</property>

配置文件的第二行出错了。尝试更改DTD文件的位置,如下所示。
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-configuration SYSTEM
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
希望这有帮助。

我能够解决问题所在。问题是我的hibernate.cfg.xml
文件不在我项目中的&#34; resources&#34; 目录下。
这解决了我遇到的所有问题,并且不需要更改文件中的代码。

很多时候,由于系统上没有连接Internet导致发生这种情况。在Hibernate Internet上工作是强制性的。
