SSH整合方案之一
SSH(方案一)1,导入spring,包含(ormDAO包)(web包)
2,导入hibernate,将hibernate的信息到写到Spring的applicationContext.xml中,使hibernate受spring管理,
配置如:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
<bean id="run" class="com.sk.run.RunHiber"><!—RunHiber类继承了HibernateDAOSupport抽象类,此类中有HibernateTemplate属性,so注入 -->
<property name="hibernateTemplate">
<ref bean="myHT"/>
</property>
</bean>
<bean id="myHT" class="org.springframework.orm.hibernate3.HibernateTemplate">
<property name="sessionFactory" >
<ref bean="mySessionFactory"/>
</property>
</bean>
<bean id="myDatasource"
class="org.apache.commons.dbcp.BasicDataSource">
<property name="driverClassName">
<value>com.microsoft.jdbc.sqlserver.SQLServerDriver</value>
</property>
<property name="url">
<value>jdbc:microsoft:sqlserver://127.0.0.1:1433</value>
</property>
<property name="username">
<value>sa</value>
</property>
</bean>
<bean id="mySessionFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource">
<ref bean="myDatasource" />
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">
org.hibernate.dialect.SQLServerDialect
</prop>
</props>
</property>
<property name="mappingResources">
<list>
<value>com/sk/bean/Student.hbm.xml</value>
</list>
</property>
</bean>
</beans>
3,导入struts()修改web.xml,添加spring的路径和监听
配置如:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.4" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
<servlet>
<servlet-name>action</servlet-name>
<servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
<init-param>
<param-name>config</param-name>
<param-value>/WEB-INF/struts-config.xml</param-value>
</init-param>
<init-param>
<param-name>debug</param-name>
<param-value>3</param-value>
</init-param>
<init-param>
<param-name>detail</param-name>
<param-value>3</param-value>
</init-param>
<load-on-startup>0</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>action</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
<!-- 指定applicationContext的位置其必须的监听器 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
</web-app>
4.所有的action都继承 ActionSupport类(此类是action的扩展类)
用WebApplicationContext 获取 spring管理的bean
代码如:
public class LoginAction extends ActionSupport {
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
LoginForm loginForm = (LoginForm) form;// TODO Auto-generated method stub
String name=loginForm.getName();
String password=loginForm.getPassword();
WebApplicationContext context=this.getWebApplicationContext();
RunHiber r=(RunHiber)context.getBean("run");
if(r.getStudent(name, password)!=null){
return mapping.findForward("succ");
}
return null;
}
}

Run类的内容:
package com.sk.run;
import java.util.Iterator;
import java.util.List;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.orm.hibernate3.HibernateTemplate;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import com.sk.bean.Student;
public class RunHiber extends HibernateDaoSupport{
public Student getStudent(String name,String password){
HibernateTemplate t= this.getHibernateTemplate();
String hql="from Student as s where s.username=?";
List list=t.find(hql, name);
Iterator i=list.iterator();
while(i.hasNext()){
Student s=(Student)i.next();
if(s.getPassword().equals(password)){
return s;
}
}
return null;
}
public static void main(String[] args) {
// TODO Auto-generated method stub
ApplicationContext context=new ClassPathXmlApplicationContext("applicationContext.xml");
RunHiber r=(RunHiber)context.getBean("run");
r.getStudent("aaa", "aaa");
}
}
