异常：无法解析配置：hibernate.cfg.xml [英] Exception:Could not parse configuration: hibernate.cfg.xml

问题描述

其实我正在尝试做hibernate日志记录。这是我的hibernate.cfg.xml文件

 <？xml version ='1.0'encoding ='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 =hbm2ddl.auto>更新< / property> 
< property name =dialect> org.hibernate.dialect.MySQLDialect< / property> 
< property name =connection.url> jdbc：mysql：// localhost：3306 / temp< / property> 
< property name =connection.username> root< / property> 
< property name =connection.password> root< / property> 
< property name =connection.driver_class> com.mysql.jdbc.Driver< / property> 
< mapping resource =employee.hbm.xml/> 
< / session-factory> 
< / hibernate-configuration> 
  

以下是例外情况...

  log4j：WARN记录器（org.hibernate.cfg.Environment）中找不到appender。 
 log4j：WARN请正确初始化log4j系统。

这是员工。 hbm.xml

 <？xml version ='1.0'encoding ='UTF-8'？> 
<！DOCTYPE hibernate-mapping PUBLIC 
 -  // Hibernate / Hibernate映射DTD 3.0 // EN
http://hibernate.sourceforge.net/hibernate-mapping-3.0 .dtd> 
 
< hibernate-mapping> 
< class name =com.subhas.mypackage.Employeetable =emp1000> 
< id name =id> 
< generator class =assigned>< / generator> 
< / id> 
 
< property name =firstName>< / property> 
< property name =lastName>< / property> 
 
< / class> 
 
< / hibernate-mapping> 
  

这是我的主要课程

  public class StoreData {
 public static void main（String [] args）{
 
 //创建配置对象
配置cfg =新配置（）; 
 cfg.configure（hibernate.cfg.xml）; 
 
 //创建会话工厂对象
 SessionFactory factory = cfg.buildSessionFactory（）; 
 
 
 //创建会话对象
会话会话= factory.openSession（）; 
 
 
 //创建交易对象
交易记录= session.beginTransaction（）; 
 
 Employee employee = new Employee（）; 
 
 employee.setId（5000）; 
 employee.setfName（Subhas）; 
 employee.setlName（Gupta）; 
 
 
 //坚持对象
 session.persist（employee）; 
 
 //提交交易对象
 transaction.commit（）; 
 session.close（）; 
 
 System.out.println（成功保存的数据）; 
 
 
 
 
 $ b  

我无法找到一个完美的解决方案。有人可以帮助我吗？谢谢。

解决方案

尝试将DOCTYPE更改为此：

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

Actually I am trying to do hibernate logging. This 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://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">  

    <hibernate-configuration>  

        <session-factory>  
            <property name="hbm2ddl.auto">update</property>  
            <property name="dialect">org.hibernate.dialect.MySQLDialect</property>  
            <property name="connection.url">jdbc:mysql://localhost:3306/temp</property>  
            <property name="connection.username">root</property>  
            <property name="connection.password">root</property>  
            <property name="connection.driver_class">com.mysql.jdbc.Driver</property>  
        <mapping resource="employee.hbm.xml"/>  
        </session-factory>   
    </hibernate-configuration>  

Here is the exception...

log4j:WARN No appenders could be found for logger (org.hibernate.cfg.Environment).
log4j:WARN Please initialize the log4j system properly.

this is employee.hbm.xml

<?xml version='1.0' encoding='UTF-8'?>  
    <!DOCTYPE hibernate-mapping PUBLIC  
     "-//Hibernate/Hibernate Mapping DTD 3.0//EN"  
     "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">  

     <hibernate-mapping>  
      <class name="com.subhas.mypackage.Employee" table="emp1000">  
        <id name="id">  
         <generator class="assigned"></generator>  
        </id>  

        <property name="firstName"></property>  
        <property name="lastName"></property>  

      </class>  

     </hibernate-mapping>  

this is my main class

public class StoreData {
public static void main(String[] args) {

    //creating configuration object
    Configuration cfg=new Configuration();
    cfg.configure("hibernate.cfg.xml");

     //creating session factory object
     SessionFactory factory=cfg.buildSessionFactory();


     //creating session object
     Session session=factory.openSession();


     //creating transaction object
     Transaction transaction=session.beginTransaction();

     Employee employee=new Employee();

     employee.setId(5000);
     employee.setfName("Subhas");
     employee.setlName("Gupta");


     //persisting the object
     session.persist(employee);

     //commit the transaction object
     transaction.commit();
     session.close();

     System.out.println("Data Saved Successfully");


    }

  }

I am unable to find a perfect solution for this. Could someone help me.? Thanks.

Try changing the DOCTYPE to this:

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