Hibernate Dialect must be explicitly set的异常

wangxy_2003

我的配置文件是这样
<?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.username">sa</property>
    <property name="hibernate.connection.url">jdbc:microsoft:sqlserver://localhost:1433:pethospital</property>
    <property name="hibernate.dialect">org.hibernate.dialect.SQLServerDialect</property>
    <property name="hibernate.connection.driver_class">com.microsoft.jdbc.sqlserver.SQLServerDriver</property>

    <mapping resource="pethospital/Host/hibernate/bean/HostInfo.hbm.xml"></mapping>
    <mapping resource="pethospital/Host/hibernate/bean/PetInfo.hbm.xml"></mapping>
  </session-factory>

</hibernate-configuration>

异常是这样
org.hibernate.HibernateException: Hibernate Dialect must be explicitly set

        at org.hibernate.dialect.DialectFactory.determineDialect(DialectFactory.java:57)

        at org.hibernate.dialect.DialectFactory.buildDialect(DialectFactory.java:39)

请问如何解决

有可能是你的hibernate配置文件找不到你的映射文件
<mapping resource="pethospital/Host/hibernate/bean/PetInfo.hbm.xml"></mapping>
注意这句，你的包路径

正确写法：public  void save(Login login) {
       
               
                        Configuration config = new Configuration();       
                        [color=#FF0000]SessionFactory sf=config.configure().buildSessionFactory();[/color]                        Session s=sf.openSession();
                        Transaction t =s.beginTransaction();
                        s.save(login);
                        t.commit();
                        s.close();
               
        }
}
错误写法：public  void save(Login login) {
       
               
                        Configuration config = new Configuration();       
                        [color=#0000FF]SessionFactory sf=config.buildSessionFactory();[/color]                        Session s=sf.openSession();
                        Transaction t =s.beginTransaction();
                        s.save(login);
                        t.commit();
                        s.close();
               
        }
}
