===============Spring+Hibernate+Struts配置===============
spring加载log4j
web.xml
< param - name > log4jConfigLocation </ param - name >
< param - value >/ WEB - INF / classes / log4j.properties </ param - value >
</ context - param >
< listener >
< listener - class > org.springframework.web.util.Log4jConfigListener </ listener - class >
</ listener >
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><!--hbm映射文件-->
<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" /> <!--所代理的bean-->
</property>
<property name="transactionAttributes">
<props>
<prop key="insert*">PROPAGATION_REQUIRED</prop> <!--以insert开头的方法加入事务管理-->
<prop key="get*">PROPAGATION_REQUIRED,readOnly</prop> <!--以get开头的方法只读-->
</props>
</property>
</bean>
6.action bean
<bean name="/loginAction" class="com.derek.action.LoginAction" singleton="false">
<property name="login">
<ref bean="loginBOProxy" /> <!--要将其使用的DAO bean加入事务管理,就必须ref他的代理bean,且在LoginAction中该属性须由其接口强制类型转换-->
</property>
</bean>

LoginInterface
public interface LoginInterface {
public boolean check(String name,String pwd);
}
Login
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
import java.util.List;
import hbm.OvertimeRecord;
public interface IRecordDao {
public List findAll(String hsql);
public void insert(OvertimeRecord or);
}
RecordDao
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)
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)
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。
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 " );
