通过plsql客户端发现oracle是可以连接的，为啥用hibernate来连接报连接拒绝呢？ 
找了半天发现是 hibernate.cfg.xml 
view plain
  1. <?xml version='1.0' encoding='utf-8'?>  
  2. <!DOCTYPE hibernate-configuration PUBLIC  
  3. "-//Hibernate/Hibernate Configuration DTD 3.0//EN"  
  4. "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">  
  5.   
  6. <hibernate-configuration>  
  7. <session-factory>  
  8.     <!-- Database connection settings -->  
  9.     <property name="connection.driver_class">oracle.jdbc.driver.OracleDriver</property>  
  10.     <property name="connection.url">jdbc:oracle:thin:@localhost:1522:orcl</property>  
  11.     <property name="connection.username">scott</property>  
  12.     <property name="connection.password">tiger</property>  
  13.   
  14.     
  15.     <property name="dialect">  
  16.         org.hibernate.dialect.MySQLDialect  
  17.     </property>  
  18.   
  19.   
  20.     <property name="show_sql">true</property>  
  21.   
  22.     <mapping resource="com/ztesoft/hibernate/helloworld/dto/Student.hbm.xml" />  
  23.       
  24. </session-factory>  
  25. </hibernate-configuration>  

配置文件中配置项
view plain
  1. <property name="connection.url">jdbc:oracle:thin:@localhost:1521:orcl</property>  
配置的有问题，由于之前在本地安装过两个oracle实例，现在正用的oracle实例的监听端口为 1522，把上面的配置项中的监听端口1521改成1522就OK了
