切记hibernate? Pojo的配置文件一定要正确

还有必须要在hibernate.cfg.xml中配置正确数据库的连接

?

hibernate.cfg.xml

<?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="connection.username">root</property>
??<property name="connection.url">
???jdbc:mysql://127.0.0.1:3306/timemngs
??</property>
??<property name="dialect">
???org.hibernate.dialect.MySQLDialect
??</property>
??<property name="myeclipse.connection.profile">product</property>
??<property name="connection.password"></property>
??<property name="connection.driver_class">
???com.mysql.jdbc.Driver
??</property>
??<property name="show_sql">false</property>
??<property name="hibernate.jdbc.batch_size">0</property>
??<property name="format_sql">true</property>
??<!-- ========== 映射 ============ -->
??<mapping resource="com/entity/xml/SysUser.hbm.xml" />
??<mapping resource="com/entity/xml/Sysmenu.hbm.xml" />
??<mapping resource="com/entity/xml/SysLog.hbm.xml" />
?</session-factory>
</hibernate-configuration>

创建一个工具类

?public static void main(String[] args) {
??// TODO Auto-generated method stub
??Configuration cfg = new Configuration().configure();
??SchemaExport se = new SchemaExport(cfg);
??se.create(true, true);
?}

?

运行着个类? 切记配置文件要正确?? 一定要在hibernate.cfg.xml中配置连接属性
