我们修改配置文件Hibernate.cfg.xml
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration
PUBLIC "-//Hibernate/Hibernate Configuration DTD//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-2.0.dtd">
<hibernate-configuration>
<session-factory>
<property name="connection.datasource">java:comp/env/jdbc/mysql</property>
<property name="show_sql">false</property>
<property name="dialect">net.sf.hibernate.dialect.MySQLDialect</property>
<mapping resource="com/yjsoft/hbm/UserInfo.hbm.xml"/>
</session-factory>
</hibernate-configuration>
修改web.xml添加
<servlet>
<servlet-name>testConnectionPooler</servlet-name>
<servlet-class>com.test.web.TestHBMServlet</servlet-class>
<load-on-startup>2</load-on-startup>
</servlet>
测试的Servlet如下
package com.test.web;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import net.sf.hibernate.HibernateException;
import net.sf.hibernate.MappingException;
import net.sf.hibernate.Session;
import net.sf.hibernate.SessionFactory;
import net.sf.hibernate.cfg.Configuration;
import org.apache.log4j.Logger;
import com.yjsoft.hbm.UserInfo;
