Spring+Hibernate+Struts配置( http://www.blogjava.net/envoydada/archive/2006/07/24/45438.html)

一.spring+struts
1.加载springContext
      通过struts-config.xml中增加plug-in插件来加载springContext
   <plug-in className="org.springframework.web.struts.ContextLoaderPlugIn">
     <set-property property="contextConfigLocation" value="/WEB-INF/ applicationContext.xml" />
   </plug-in>
   applicationContext.xml为spring的配置文件

2.将strutsAction交给Spring容器进行管理
      修改struts-config.xml中的action属性,action的type值不指定具体的实现类,统一修改成代理类
   <action input="/login.jsp"
         name="loginActionForm"
         path="/loginAction"
        scope="request"
         type="org.springframework.web.struts.DelegatingActionProxy"
         validate="false">
      <forward name="success" path="/success.jsp" />
      <forward name="failure" path="/failure.jsp" />
    </action>

3.在applicationContext.xml中的bean name值设定与struts-config.xml中action path值相对应,以使代理类 DelegatingActionProxy能够根据传入的path在springContext中找到相应的bean,并将实例返回给struts.
<bean name="/loginAction" class="com.derek.action.LoginAction" singleton="false">
<property name="login">
    <ref bean="loginBOProxy" />
</property>
</bean>

二.spring+hibernate
   1.dateSource
      在springContext中设置dateSource Bean
     <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="net.sourceforge.jtds.jdbc.Driver"></property>
      <property name="url" value="jdbc:jtds:sqlserver://192.168.56.32:1433/testDB"></property>
       <property name="username" value="it"></property>
        <property name="password" value="it"></property>
     </bean>
     2.sessionFactory
       在springContext中设置sessionFactory Bean
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource"></property>
    <property name="mappingResources">
        <list>
          <value>hbm\OvertimeRecord.hbm.xml</value>
          <value>hbm\OvertimePermit.hbm.xml</value>
        </list>
    </property>
    <property name="hibernateProperties">
        <props>
           <prop key="hibernate.dialect">org.hibernate.dialect.SQLServerDialect</prop>
           <prop key="hibernate.show_sql">true</prop>
           <prop key="hibernate.jdbc.fetch_size">50</prop>
           <prop key="hibernate.jdbc.batch_size">20</prop>
        </props>
    </property>
  </bean>

3.transactionManager
   在springContext中设置transactionManager Bean
   <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
     <property name="sessionFactory">
       <ref local="sessionFactory" />
     </property>
   </bean>

   4.DAO bean
      <bean id="Ilogin" class="com.derek.business.Login">
         <property name="sessionFactory">
              <ref local="sessionFactory"/>
        </property>
      </bean>
      public class Login extends HibernateDaoSupport implements LoginInterface
      DAO 继承HibernateDaoSupport
      HibernateSupport实现了HibernateTemplate和SessionFactory实例的关联, HibernateTemplate对Hibernate Session操作进行了封装，HibernateTemplate.execute方法则是一封装机制的核心. 借助HibernateTemplate我们可以脱离每次数据操作必须首先获得Session实例、启动事务、提交/回滚事务以及烦杂的try/catch/finally的繁琐操作.
        Spring中的事务管理实际上是基于动态AOP机制实现，为了实现动态AOP，Spring在默认情况下会使用Java DynamicProxy，但是，Dynamic Proxy要求其代理的对象必须实现一个接口，该接口定义了准备进行代理的方法。而对于没有实现任何接口的Java Class，需要采用其他方式，Spring通过CGLib实现这一功能。

   5.DAOProxy 代理bean
        通过代理,将上面的DAO bean 纳入到spring容器的事务管理中,并在其中设置对哪些方法进行事务管理
     <bean id="loginBOProxy" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
           <property name="transactionManager">
                <ref bean="transactionManager" />
           </property>
           <property name="target">
                <ref local="Ilogin" /> 
           </property>
           <property name="transactionAttributes">
                <props>
                     <prop key="insert*">PROPAGATION_REQUIRED</prop> 
                     <prop key="get*">PROPAGATION_REQUIRED,readOnly</prop> 
                </props>
           </property>
      </bean>

    6.action bean
      <bean name="/loginAction" class="com.derek.action.LoginAction" singleton="false">
        <property name="login">
            <ref bean="loginBOProxy" /> 
         </property>
      </bean>

LoginInterface

package com.derek.myinterface;

public interface LoginInterface {
public boolean check(String name,String pwd);
}

package com.derek.business;

import com.derek.myinterface.LoginInterface;
import org.hibernate.SessionFactory;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import java.util.List;

public class Login extends HibernateDaoSupport implements LoginInterface{
     private SessionFactory sessionFactory;
     private String hsql = " from OvertimePermit where account=? and password=? " ;
     public Login() {}
     public boolean check(String name,String pwd){
        String condition[] = {name, pwd}; // 查询条件
         /**
         * 借助HibernateTemplate我们可以脱离每次数据操作必须首先
         * 获得Session实例、启动事务、提交/回滚事务以及烦杂的try/catch/finally的繁琐操作
          */
        List l = this .getHibernateTemplate().find(hsql, condition);

         if (l.size() > 0 ) return true ;
           else return false ;
    }
}

RecordDaoInterface

package com.derek.myinterface;

import java.util.List;
import hbm.OvertimeRecord;

public interface IRecordDao {
public List findAll(String hsql);
public void insert(OvertimeRecord or);
}

RecordDao

package com.derek.business;

import com.derek.myinterface.IRecordDao;
import java.util.List;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import org.hibernate.SessionFactory;
import hbm.OvertimeRecord;

public class RecordDao extends HibernateDaoSupport implements IRecordDao{
     private SessionFactory sessionFactory;
     public RecordDao() {
    }

     public List findAll(String hsql) {
        return this .getHibernateTemplate().find(hsql);
    }

     public void insert(OvertimeRecord or) {
         this .getHibernateTemplate().saveOrUpdate(or);
    }
}

LoginAction通过容器注入的Login实例完成业务操作(必须由接口强制类型转化)

package com.derek.action;

import javax.servlet.http. * ;
import com.derek.form. * ;
import org.apache.struts.action. * ;
import org.apache.log4j.Logger;
import com.derek.myinterface.LoginInterface;

public class LoginAction extends Action {
     private LoginInterface login;
     public ActionForward execute(ActionMapping actionMapping,
                                 ActionForm actionForm,
                                 HttpServletRequest servletRequest,
                                 HttpServletResponse servletResponse) {
        Logger log = Logger.getLogger( this .getClass().getName());
        LoginActionForm loginActionForm = (LoginActionForm) actionForm;
        String name = loginActionForm.getName();
        String pwd = loginActionForm.getPwd();
         boolean TF = login.check(name,pwd);
         if (TF){ log.warn( " LoginSuccess------------ " );; return actionMapping.findForward( " success " );}
           else { log.warn( " LoginFailure------------ " );; return actionMapping.findForward( " failure " );}
    }
     public void setLogin(LoginInterface Ilogin) { this .login = Ilogin;}
     public LoginInterface getLogin() { return login;}
}

类中直接通过Context获得bean实例(必须通过代理类获得实例且由其接口强制类型转化)

package com.derek.pub;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;
import com.derek.myinterface.IRecordDao;
import java.util.List;
import hbm.OvertimeRecord;

public class Untitled1 {
     public Untitled1() {
    ApplicationContext ctx = new FileSystemXmlApplicationContext( " applicationContext.xml " );
    IRecordDao recordDao = (IRecordDao)ctx.getBean( " RecordDaoProxy " );
    OvertimeRecord newor = new OvertimeRecord( " 004104 " , "dada " , "1 00120 " , "it " , " 2006/04/02 " , " 2006/04/02 " , " 001145 " , "david " , " 001145 " , "david " , " 00 " , " 00 " , " 1 " , " 1 " , " 1 " , " 1 " );
    newor.setMark( " 0 " );
    recordDao.insert(newor);
    List l = recordDao.findAll( " from OvertimeRecord " );
     for ( int i = 0 ;i < l.size();i ++ ){
    OvertimeRecord or = (OvertimeRecord)l.get(i);
    System.out.println(or.getId());
    }
    }
     public static void main(String[] a){
    Untitled1 u = new Untitled1();
    }
}

一个Spring application context的定义能够被很多种不同的上下文实现所读取，比如FileSystemXmlApplicationContext 和 ClassPathXmlApplicationContext以及XmlWebApplicationContext。默认的情况下，一个web应用程序会从”WEB-INF/applicationContext.xml”中得到root context。在所有的Spring应用中，XML文件中定义的application context会把所有相关的application beans连接起来，包括Hibernate session factory以及数据访问和业务对象（就像上面定义的那些bean）。它们中的大部分都不会意识到被Spring容器所管理，甚至在同其他bean合作的时候，因为它们仅仅遵循JavaBeans的规范。一个bean属性及可以表示值参数，也可以是其他的合作bean。下面的bean定义能够作为Spring web MVC context的一部分，在最基础的 application context中访问business beans。

ApplicationContext context = WebApplicationContextUtils.getWebApplicationContext(servletContext);
ProductService productService = (ProductService) context.getBean( " myProductService " );
ApplicationContext context =
     new FileSystemXmlApplicationContext( " C:/myContext.xml " );
ProductService productService =
    (ProductService) context.getBean( " myProductService " );
ApplicationContext context =
     new ClassPathXmlApplicationContext( " myContext.xml " );
ProductService productService =
    (ProductService) context.getBean( " myProductService " );

# re: Spring+Hibernate+Struts 2006-07-25 09:15 Derek.G

你用的是hibernate3.0吧! 但你的spring配置文件中不是
<bean id="sessionFactory" class="org.springframework.orm.hibernate.LocalSessionFactoryBean">

应该是:
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
你试试! 回复

# re: Spring+Hibernate+Struts 2006-07-25 09:22 Derek.G

在spring配置文件中配置一下action 如:
<bean name="/loginAction" class="com.derek.action.LoginAction" singleton="false">
<property name="login">
<ref bean="loginBOProxy" />
</property>
</bean>

和在struts-config配置文件中声明loginAction的
type = "org.springframework.web.struts.DelegatingActionProxy "

那么在action中有set,get方法, spring 会帮你注入你定义的bean,无须你再自己用WebApplicationContextUtils去获得bean实例
