首先应该配置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="dialect">
org.hibernate.dialect.Oracle9Dialect
</property>
<property name="connection.url">
hjdbc:oracle:thin:@localhost:1521:orcl
</property>
<property name="connection.username">chy</property>
<property name="connection.password">chy</property>
<property name="connection.driver_class">
oracle.jdbc.driver.OracleDriver
</property>
<property name="myeclipse.connection.profile">news</property>
<property name="show_sql">true</property>
<property name="connection.autocommit">true</property>
<property name="current_session_context_class">thread</property>
<property name="hbm2ddl.auto">save-update</property>
<mapping resource="bean/News.hbm.xml" />
<mapping resource="bean/Review.hbm.xml" />
<mapping resource="bean/Topic.hbm.xml" />
<mapping resource="bean/Users.hbm.xml" />
</session-factory>
</hibernate-configuration>
然后再类HibernateSessionFactory调用
package hibernate;
import org.hibernate.HibernateException;
import org.hibernate.Session;
import org.hibernate.cfg.Configuration;
/**
* Configures and provides access to Hibernate sessions, tied to the
* current thread of execution. Follows the Thread Local Session
* pattern, see {@link http://hibernate.org/42.html }.
*/
public class HibernateSessionFactory {
/**
* Location of hibernate.cfg.xml file.
* Location should be on the classpath as Hibernate uses
* #resourceAsStream style lookup for its configuration file.
* The default classpath location of the hibernate config file is
* in the default package. Use #setConfigFile() to update
* the location of the configuration file for the current session.
*/
private static String CONFIG_FILE_LOCATION = "/hibernate.cfg.xml";
private static final ThreadLocal<Session> threadLocal = new ThreadLocal<Session>();
private static Configuration configuration = new Configuration();
private static org.hibernate.SessionFactory sessionFactory;
private static String configFile = CONFIG_FILE_LOCATION;
static {
try {
configuration.configure(configFile);
sessionFactory = configuration.buildSessionFactory();
} catch (Exception e) {
System.err
.println("%%%% Error Creating SessionFactory %%%%");
e.printStackTrace();
}
}
private HibernateSessionFactory() {
}
/**
* Returns the ThreadLocal Session instance. Lazy initialize
* the <code>SessionFactory</code> if needed.
*
* @return Session
* @throws HibernateException
*/
public static Session getSession() throws HibernateException {
Session session = (Session) threadLocal.get();
if (session == null || !session.isOpen()) {
if (sessionFactory == null) {
rebuildSessionFactory();
}
session = (sessionFactory != null) ? sessionFactory.openSession()
: null;
threadLocal.set(session);
}
return session;
}
/**
* Rebuild hibernate session factory
*
*/
public static void rebuildSessionFactory() {
try {
configuration.configure(configFile);
sessionFactory = configuration.buildSessionFactory();
} catch (Exception e) {
System.err
.println("%%%% Error Creating SessionFactory %%%%");
e.printStackTrace();
}
}
/**
* Close the single hibernate session instance.
*
* @throws HibernateException
*/
public static void closeSession() throws HibernateException {
Session session = (Session) threadLocal.get();
threadLocal.set(null);
if (session != null) {
session.close();
}
}
/**
* return session factory
*
*/
public static org.hibernate.SessionFactory getSessionFactory() {
return sessionFactory;
}
/**
* return session factory
*
* session factory will be rebuilded in the next call
*/
public static void setConfigFile(String configFile) {
HibernateSessionFactory.configFile = configFile;
sessionFactory = null;
}
/**
* return hibernate configuration
*
*/
public static Configuration getConfiguration() {
return configuration;
}
}
然后再applicationContext.xml文件中把所有要用到的biz，dao,controller写在里面
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd"> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="configLocation" value="classpath:hibernate.cfg.xml"> </property> </bean> <bean id="TopicDAO" class="dao.TopicDAO"> <property name="sessionFactory"> <ref bean="sessionFactory" /> </property> </bean> <bean id="UsersDAO" class="dao.UsersDAO"> <property name="sessionFactory"> <ref bean="sessionFactory" /> </property> </bean> <bean id="ReviewDAO" class="dao.ReviewDAO"> <property name="sessionFactory"> <ref bean="sessionFactory" /> </property> </bean> <bean id="NewsDAO" class="dao.NewsDAO"> <property name="sessionFactory"> <ref bean="sessionFactory" /> </property> </bean> <bean id="UserBizImpl" class="biz.impl.UserBizImpl"> <property name="ud"> <ref bean="UsersDAO" /> </property> </bean> <bean id="UserAction" class="action.UserAction" > <property name="ub"> <ref bean="UserBizImpl" /> </property> </bean> <bean id="TopicBizImpl" class="biz.impl.TopicBizImpl"> <property name="td"> <ref bean="TopicDAO" /> </property> </bean> <bean id="TopicAction" class="action.TopicAction" > <property name="tb"> <ref bean="TopicBizImpl" /> </property> </bean> <bean id="NewsBizImpl" class="biz.impl.NewsBizImpl"> <property name="nd"> <ref bean="NewsDAO" /> </property> </bean> <bean id="NewsAction" class="action.NewsAction" > <property name="nb"> <ref bean="NewsBizImpl" /> </property> <property name="tb"> <ref bean="TopicBizImpl" /> </property> <property name="rb"> <ref bean="ReviewBizImpl" /> </property> </bean> <bean id="ReviewBizImpl" class="biz.impl.ReviewBizImpl"> <property name="rd"> <ref bean="ReviewDAO" /> </property> </bean> <bean id="ReviewAction" class="action.ReviewAction" > <property name="rb"> <ref bean="ReviewBizImpl" /> </property> <property name="nb"> <ref bean="NewsBizImpl" /> </property> </bean> </beans>
然后是最重要的文件，web.xml综合监听和配置
<?xml version="1.0" encoding="UTF-8"?> <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <filter> <filter-name>CharacterEncodingFilter</filter-name> <filter-class>filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> </filter> <filter-mapping> <filter-name>CharacterEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <filter> <filter-name>struts2</filter-name> <filter-class> org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> </web-app>
