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

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. <hibernate-configuration>
6. <session-factory>
7. <!-- Database connection settings -->
8. <property name="connection.driver_class">oracle.jdbc.driver.OracleDriver</property>
9. <property name="connection.url">jdbc:oracle:thin:@localhost:1522:orcl</property>
10. <property name="connection.username">scott</property>
11. <property name="connection.password">tiger</property>
12. <property name="dialect">
13. org.hibernate.dialect.MySQLDialect
14. </property>
15. <property name="show_sql">true</property>
16. <mapping resource="com/ztesoft/hibernate/helloworld/dto/Student.hbm.xml" />
17. </session-factory>
18. </hibernate-configuration>

配置文件中配置项

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
