Hibernate：无法解析配置：hibernate.cfg.xml？

问题描述

当试图在我的应用程序中使用 Hibernate 时出现以下错误：

  org.hibernate.HibernateException：无法解析配置：hibernate.cfg.xml 
  

这是什么造成的？请参阅 hibernate.cfg.xml ，输出和 Runner类 below？

注意：我已经看过

 <？xml version = 1.0encoding =UTF-8？> 
<！DOCTYPE hibernate-configuration PUBLIC 
 -  // Hibernate / Hibernate配置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>根< / property> 
< property name =hibernate.connection.password>根< / 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> 
  

I am getting the following error when trying to use Hibernate withing my application:

org.hibernate.HibernateException: Could not parse configuration: hibernate.cfg.xml

What is causing this? Please see hibernate.cfg.xml , output and Runner class below?

Note: I have looked at this answer and tried to fix it using suggestions, but with no luck.

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:3306/test-db</property>
            <property name="connection.username">user</property>
            <property name="connection.password">password</property>

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

            <!-- Echo all executed SQL to stdout -->
            <property name="show_sql">true</property>

            <!-- Use XML-based mapping metadata -->
            <!-- <mapping resource="domain/Message.hbm.xml"/> -->

            <!-- Use Annotation-based mapping metadata -->
            <mapping class="entity.Message"/>

        </session-factory>
    </hibernate-configuration>

解决方案

Can you check with the below CFG file which I have used and make sure the CFG file will present under the SRC directory. If you are keeping in another directory, make sure you are passing the path while getting configuration instance.

<?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">

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

        <property name="hibernate.connection.username"> root </property>
