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>”-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//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">

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

<beans>

       <bean id="LoginAction" class="com.ln.spring.LoginAction">

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propertyname名字一样的属性值,并且需要有这个属性值的gettersetter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>

       <bean id="data1" class="com.ln.spring.MyAction">

              <property name="message">

                     <value>liang</value>

              </property>               

       </bean>

       <bean id="urlMapping"       class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">

              <property name="mappings">

                     <props>

                            <prop key="/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 "-//Apache Software 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strutsaction所以有两个地方要注意:

1  Action”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//DTD BEAN//EN"

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

<beans>

       <bean name="/login" class="com.ln.struts.LoginAction"

              singleton="false">

此处的beanstruts-config.xml中的action相对应,namestruts-config.xmlactionpath一致

              <property name="msg">

                     <value>Hello World</value>

              </property>

       </bean>

</beans>

 


 

2Spring配置文件总结  

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

3Spring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DataSourceTransactionManager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。

    DataSourceTransactionManager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SessionFactoryTransactionManager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="Spring事务配置 (2)" 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]-->Spring事务配置 (2)<!--[endif]-->

    根据代理机制的不同,总结了五种Spring事务的配置方式,配置文件如下:

    第一种方式:每个Bean都有一个代理

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi
="http://www.w3.org/2001/XMLSchema-instance"

    xsi:schemaLocation

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


   
<bean id="sessionFactory" 
            class
="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> 
       
<property name="configLocation" value="classpath:hibernate.cfg.xml" /> 
       
<property name="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">
       
<property name="sessionFactory" ref="sessionFactory" />
   
</bean>
   
   
<!-- 配置DAO -->
   
<bean id="userDaoTarget" class="com.bluesky.spring.dao.UserDaoImpl">
       
<property name="sessionFactory" ref="sessionFactory" />
   
</bean>
   
   
<bean id="userDao" 
        class
="org.springframework.transaction.interceptor.TransactionProxyFactoryBean"> 
          
<!-- 配置事务管理器 --> 
          
<property name="transactionManager" ref="transactionManager" />    
       
<property name="target" ref="userDaoTarget" /> 
        
<property name="proxyInterfaces" value="com.bluesky.spring.dao.GeneratorDao" />
       
<!-- 配置事务属性 --> 
       
<property name="transactionAttributes">

<prop key="*">PROPAGATION_REQUIRED</prop>
           
</props> 
       
</property> 
   
</bean> 
</beans>

    第二种方式:所有Bean共享一个代理基类

<?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

    xmlns:aop

           http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd">


   
<bean id="sessionFactory" 
            class
="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> 
       
<property name="configLocation" value="classpath:hibernate.cfg.xml" /> 
       
<property name="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">
       
<property name="sessionFactory" ref="sessionFactory" />
   
</bean>
   
   
<bean id="transactionBase" 
            class
="org.springframework.transaction.interceptor.TransactionProxyFactoryBean" 
            lazy-init
="true" abstract="true"> 
       
<!-- 配置事务管理器 --> 
       
<property name="transactionManager" ref="transactionManager" /> 
       
<!-- 配置事务属性 --> 
       
<property name="transactionAttributes"> 
           
<props> 
               
<prop key="*">PROPAGATION_REQUIRED</prop> 
           
</props> 
       
</property> 
   
</bean>   
  
   
<!-- 配置DAO -->
   
<bean id="userDaoTarget" class="com.bluesky.spring.dao.UserDaoImpl">
       
<property name="sessionFactory" ref="sessionFactory" />
   
</bean>
   
   
<bean id="userDao" parent="transactionBase" > 
       
<property name="target" ref="userDaoTarget" />  
   
</bean>
</beans>

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"
    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/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd">


   
<bean id="sessionFactory" 
            class
="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> 
       
<property name="configLocation" value="classpath:hibernate.cfg.xml" /> 
       
<property name="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">
       
<property name="sessionFactory" ref="sessionFactory" />
   
</bean> 
  
   
<bean id="transactionInterceptor" 
        class
="org.springframework.transaction.interceptor.TransactionInterceptor"> 
       
<property name="transactionManager" ref="transactionManager" /> 
       
<!-- 配置事务属性 --> 
       
<property name="transactionAttributes"> 
           
<props> 
               
<prop key="*">PROPAGATION_REQUIRED</prop> 
           
</props> 
       
</property> 
   
</bean>
     
   
<bean class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator"> 
       
<property name="beanNames"> 
           
<list> 
               
<value>*Dao</value>
           
</list> 
       
</property> 
       
<property name="interceptorNames"> 
           
<list> 
               
<value>transactionInterceptor</value> 
           
</list> 
       
</property> 
   
</bean> 
 
   
<!-- 配置DAO -->
   
<bean id="userDao" class="com.bluesky.spring.dao.UserDaoImpl">
       
<property name="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"
    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/aop http://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" />

   
<bean id="sessionFactory" 
            class
="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> 
       
<property name="configLocation" value="classpath:hibernate.cfg.xml" /> 
       
<property name="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">
       
<property name="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:pointcut id="interceptorPointCuts"
            expression
="execution(* com.bluesky.spring.dao.*.*(..))" />
       
<aop:advisor advice-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/aop http://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"> 
       
<property name="configLocation" value="classpath:hibernate.cfg.xml" /> 
       
<property name="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">
       
<property name="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;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import org.springframework.stereotype.Component;

import com.bluesky.spring.domain.User;

@Transactional
@Component("userDao")
public class UserDaoImpl extends HibernateDaoSupport 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="http://www.blogjava.net/Images/dot.gif" 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]-->http://www.blogjava.net/Images/dot.gif<!--[endif]-->
}
