hibernate.cfg.xml文件，必不可少的一个xml文件，上面附有数据库的用户名，密码，链接字符串，方言等信息，还包含映射的文件路径：
<?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"> <!-- Generated by MyEclipse Hibernate Tools. --> <hibernate-configuration> <session-factory> <property name="dialect"> org.hibernate.dialect.Oracle9Dialect </property> <property name="connection.url"> jdbc:oracle:thin:@127.0.0.1:1521:orcl </property> <property name="connection.username">pro</property> <property name="connection.password">pro</property> <property name="connection.driver_class"> oracle.jdbc.OracleDriver </property> <property name="myeclipse.connection.profile">pro</property> <property name="show_sql">true</property> <property name="format_sql">true</property> <property name="current_session_context_class">thread</property> <mapping resource="org/entity/Dept.hbm.xml" /> <mapping resource="org/entity/Emp.hbm.xml" /> </session-factory> </hibernate-configuration>
