初学spring，配置实例！！2011年10月12日, AM 11:05:17

1、在建立单纯的spring项目时，web.xml文件如下：

<?xml version="1.0"encoding="UTF-8"?>

<!DOCTYPE web-app PUBLIC "-//Sun Microsystems,Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">

<web-app>

??????<servlet>

?????????????<servlet-name>spring</servlet-name>

?????????????<servlet-class>

????????????????????org.springframework.web.servlet.DispatcherServlet

?????????????</servlet-class>

?????????????<init-param>

????????????????????<param-name>contextConfigLocation</param-name>

??????<param-value>/WEB-INF/application.xml</param-value>

?????????????</init-param>

?????? 上面加框的一段是用来指定spring配置文件的（可以为任意名，如上），也可以不写，不写时spring的配置文件默认名为:?? “<servlet-name>”名-servlet.xml。（如此处的<servlet-name>的值为“spring”,则配置文件名为：springt-servlet.xml）

<load-on-startup>1</load-on-startup>

??????</servlet>

??????<servlet-mapping>

?????????????<servlet-name>spring</servlet-name>

?????????????<url-pattern>*.do</url-pattern>

??????</servlet-mapping>

</web-app>

?

spring配置文件（这里假定为spring-servlet.xml）如下：

<?xml version="1.0"encoding="UTF-8"?>

<!DOCTYPE beans PUBLIC "-//SPRING//DTDBEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">

<!--? -Application context definition for "springapp"DispatcherServlet.? -->

<beans>

?????? <beanid="LoginAction" style="text-align: left;">在bean中配置有属性（包括bean格式的属性）时，bean对应的java文件内必须要定义一个与property的name名字一样的属性值，并且需要有这个属性值的getter和setter方法。

?????????????<property name="msg">????????????????????

<value>Hello World</value>

?????????????</property>

?????????????<property name="data">

????????????????????<ref bean="data1" />

当一个bean中有格式为bean的属性时，用“<ref bean="bean-name" />”来指定，在指定”bean-name”后还要在下面用”<bean></bean>”来指定这个bean格式的属性的值,此时”<bean></bean>”中的”id”必须与前面指定的”bean-name”一致。

?????????????</property>

??????</bean>

?????? <beanid="data1" style="text-align: left;">?????????????<property name="message">

????????????????????<value>liang</value>

?????????????</property>???????????????

??????</bean>

?????? <beanid="urlMapping"??????style="text-align: left;">?????????????<property name="mappings">

????????????????????<props>

??????????????????????????? <propkey="/login.do">LoginAction</prop>

????????????????????</props>

?????????????</property>

??????</bean>

</beans>

?

而在建立spring+struts项目时，web.xml文件按照struts项目的规格建立，在此不在多说，而在此时struts-config.xml如下：

<?xml version="1.0"encoding="UTF-8"?>

<!DOCTYPE struts-config PUBLIC "-//ApacheSoftware Foundation//DTD Struts Configuration 1.1//EN" "http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd">

<struts-config>

??????<form-beans>

???????????<form-bean name="loginForm"type="com.ln.struts.LoginForm" />

??????</form-beans>

?????? <action-mappings>

?????????????<action path="/login"

??????type="org.springframework.web.struts.DelegatingActionProxy"

????????????????????name="loginForm">

????????????????????<forward name="success" path="/main.jsp" />

????????????????????<forward name="failure" path="/loginfail.jsp"/>

?????????????</action>

??????</action-mappings>

?????? <plug-in

??????className="org.springframework.web.struts.ContextLoaderPlugIn">

?????????????<set-property property="contextConfigLocation"

????????????????????value="/WEB-INF/spring-servlet.xml" />

??????</plug-in>

</struts-config>

在这个配置文件中，由于使用spring来管理struts的action所以有两个地方要注意：

1．? Action的”type”指向spring里定义的用来处理action的类，而不是自己写的action.

2.增加了一个”<plug-in></plug-in>“来指定spring配置文件。

?

?

?

?

此时spring-servlet.xml配置文件如下：

<?xml version="1.0"encoding="UTF-8"?>

<!DOCTYPE beans PUBLIC "-//SPRING//DTDBEAN//EN"

"http://www.springframework.org/dtd/spring-beans.dtd">

<beans>

?????? <beanname="/login" style="text-align: left;">?????????????singleton="false">

此处的bean与struts-config.xml中的action相对应，name与struts-config.xml中action的path一致

?????????????<property name="msg">

????????????????????<value>Hello World</value>

?????????? ???</property>

??????</bean>

</beans>

?

2、Spring配置文件总结??

首先来看一个标准的Spring配置文件 applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

?<!-- 配置数据持久层 -->

3、Spring事务配置的五种方式

??? 前段时间对Spring的事务配置做了比较深入的研究，在此之间对Spring的事务配置虽说也配置过，但是一直没有一个清楚的认识。通过这次的学习发觉Spring的事务配置只要把思路理清，还是比较好掌握的。

??? 总结如下：

??? Spring配置文件中关于事务配置总是由三个组成部分，分别是DataSource、TransactionManager和代理机制这三部分，无论哪种配置方式，一般变化的只是代理机制这部分。

??? DataSource、TransactionManager这两部分只是会根据数据访问方式有所变化，比如使用Hibernate进行数据访问 时，DataSource实际为SessionFactory，TransactionManager的实现为 HibernateTransactionManager。

??? 具体如下图：

<!--[if gte vml 1]><v:shapetype id="_x0000_t75" coordsize="21600,21600" o:spt="75" o:preferrelative="t" path="m@4@5l@4@11@9@11@9@5xe" filled="f" stroked="f"> <v:stroke joinstyle="miter" /> <v:formulas> <v:f eqn="if lineDrawn pixelLineWidth 0" /> <v:f eqn="sum @0 1 0" /> <v:f eqn="sum 0 0 @1" /> <v:f eqn="prod @2 1 2" /> <v:f eqn="prod @3 21600 pixelWidth" /> <v:f eqn="prod @3 21600 pixelHeight" /> <v:f eqn="sum @0 0 1" /> <v:f eqn="prod @6 1 2" /> <v:f eqn="prod @7 21600 pixelWidth" /> <v:f eqn="sum @8 21600 0" /> <v:f eqn="prod @7 21600 pixelHeight" /> <v:f eqn="sum @10 21600 0" /> </v:formulas> <v:path o:extrusionok="f" gradientshapeok="t" o:connecttype="rect" /> <o:lock v:ext="edit" aspectratio="t" /></v:shapetype><v:shape id="图片_x0020_1" o:spid="_x0000_i1026" type="#_x0000_t75" alt="初学spring，配备实例！2011年10月12日, AM 11:05:17" href="http://www.blogjava.net/images/blogjava_net/robbie/WindowsLiveWriter/Spring_9C9C/Spring%E4%BA%8B%E5%8A%A1%E9%85%8D%E7%BD%AE%20(2).jpg" style='width:490.5pt;height:283.5pt;visibility:visible;mso-wrap-style:square' o:button="t"> <v:fill o:detectmouseclick="t" /> <v:imagedata src="file:///C:\Users\ADMINI~1\AppData\Local\Temp\msohtmlclip1\01\clip_image001.jpg" o:title="Spring事务配置 (2)" /></v:shape><![endif]--><!--[if !vml]-->初学spring，配备实例！2011年10月12日, AM 11:05:17<!--[endif]-->

第三种方式：使用拦截器

<?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:context="http://www.springframework.org/schema/context"
??? xmlns:aop="http://www.springframework.org/schema/aop"

?
??? <!-- 配置DAO -->
??? <bean id="userDao" class="com.bluesky.spring.dao.UserDaoImpl">
??????? <propertyname="sessionFactory" ref="sessionFactory"?/>
??? </bean>
</beans>

第四种方式：使用tx标签配置的拦截器

<?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:context="http://www.springframework.org/schema/context"

??????????http://www.springframework.org/schema/context
??????????http://www.springframework.org/schema/context/spring-context-2.5.xsd
??????????http://www.springframework.org/schema/aophttp://www.springframework.org/schema/aop/spring-aop-2.5.xsd
??????????http://www.springframework.org/schema/txhttp://www.springframework.org/schema/tx/spring-tx-2.5.xsd">

??? <context:annotation-config />
??? <context:component-scan base-package="com.bluesky"?/>

??? <bean id="sessionFactory"?
??????????? class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">?
??????? <propertyname="configLocation" value="classpath:hibernate.cfg.xml"?/>?
??????? <propertyname="configurationClass" value="org.hibernate.cfg.AnnotationConfiguration"?/>
??? </bean>?

??? <!-- 定义事务管理器（声明式的事务） -->?
??? <bean id="transactionManager"
??????? class="org.springframework.orm.hibernate3.HibernateTransactionManager">
??????? <propertyname="sessionFactory" ref="sessionFactory"?/>
??? </bean>

??? <tx:advice id="txAdvice" transaction-manager="transactionManager">
??????? <tx:attributes>
??????????? <tx:method name="*" propagation="REQUIRED"?/>
??????? </tx:attributes>
??? </tx:advice>
???
??? <aop:config>
??????? <aop:pointcutid="interceptorPointCuts"
??????????? expression="execution(*com.bluesky.spring.dao.*.*(..))"?/>
??????? <aop:advisoradvice-ref="txAdvice"
??????????? pointcut-ref="interceptorPointCuts"?/>???????
??? </aop:config>?????
</beans>

第五种方式：全注解

<?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:context="http://www.springframework.org/schema/context"
??? xmlns:aop="http://www.springframework.org/schema/aop"
??? xmlns:tx="http://www.springframework.org/schema/tx"
??? xsi:schemaLocation="http://www.springframework.org/schema/beans
??????????http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
??????????http://www.springframework.org/schema/context
?????????? http://www.springframework.org/schema/context/spring-context-2.5.xsd
??????????http://www.springframework.org/schema/aophttp://www.springframework.org/schema/aop/spring-aop-2.5.xsd
??????????http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd">

??? <context:annotation-config />
??? <context:component-scan base-package="com.bluesky"?/>

??? <tx:annotation-driven transaction-manager="transactionManager"/>

??? <bean id="sessionFactory"?
??????????? class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">?
??????? <propertyname="configLocation" value="classpath:hibernate.cfg.xml"?/>?
??????? <propertyname="configurationClass" value="org.hibernate.cfg.AnnotationConfiguration"?/>
??? </bean>?

??? <!-- 定义事务管理器（声明式的事务） -->?
??? <bean id="transactionManager"
??????? class="org.springframework.orm.hibernate3.HibernateTransactionManager">
??????? <propertyname="sessionFactory" ref="sessionFactory"?/>
??? </bean>
???
</beans>

此时在DAO上需加上@Transactional注解，如下：

package com.bluesky.spring.dao;

import java.util.List;

import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
importorg.springframework.orm.hibernate3.support.HibernateDaoSupport;
import org.springframework.stereotype.Component;

import com.bluesky.spring.domain.User;

@Transactional
@Component("userDao")
public?class UserDaoImpl extendsHibernateDaoSupport implements UserDao {

??? public List<User> listUsers() {
??????? return?this.getSession().createQuery("from User").list();
??? }
???
??? <!--[if gte vml 1]><v:shape id="图片_x0020_2" o:spid="_x0000_i1025" type="#_x0000_t75" alt="初学spring，配备实例！2011年10月12日, AM 11:05:17" style='width:11.25pt;height:15pt;visibility:visible;mso-wrap-style:square'> <v:imagedata src="file:///C:\Users\ADMINI~1\AppData\Local\Temp\msohtmlclip1\01\clip_image002.gif" o:title="dot" /></v:shape><![endif]--><!--[if !vml]-->初学spring，配备实例！2011年10月12日, AM 11:05:17<!--[endif]-->
