SSH整合之配置文件

1. web.xml文件的配置：

<?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"> <!-- 配置字符編碼過濾器（解決亂碼問題） <filter> <filter-name>encoding</filter-name> <filter-class> org.springframework.web.filter.CharacterEncodingFilter </filter-class> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> </filter> <filter-mapping> <filter-name>encoding</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> --> <!-- 解決因session關閉而導致的延遲加載例外的問題 --> <filter> <filter-name>OpenSessionInViewFilter</filter-name> <filter-class> org.springframework.orm.hibernate3.support.OpenSessionInViewFilter </filter-class> </filter> <filter-mapping> <filter-name>OpenSessionInViewFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 指定spring的配置文件，默認從web根目錄尋找配置文件，我們可以通過spring提供的classpath:前綴指定從類路徑下尋找 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <!-- 對Spring容器進行實例化,並把實例存放在application的屬性裏 --> <listener> <listener-class> org.springframework.web.context.ContextLoaderListener </listener-class> </listener> <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> <welcome-file-list> <welcome-file>Login.html</welcome-file> </welcome-file-list> </web-app>

 

Web.xml配置文件需要做以下幾件事情:配置ActionServlet,Spring容器監聽器（字符處理，session已關閉異常處理)括號內爲可選。

 

需要注意的地方:

  a.過濾器的配置必須寫在Servlet配置前，比如字符處理   org.springframework.web.filter.CharacterEncodingFilter 必須配置在ActionServlet註冊之前。

  b.過濾器名和參數名要正確，是固定不變的。比如在配置Spring容器監聽時,上下文參數名稱必須爲contextConfigLocation. 等等

 

2.applicationContext.xml

<?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="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="configLocation" value="classpath:hibernate.cfg.xml"> </property> </bean> <bean id="template" class="org.springframework.orm.hibernate3.HibernateTemplate"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <bean id="common" class="com.ssh.common.Common"> <property name="hibernateTemplate" ref="template"></property> </bean> <bean id="pdao" class="com.ssh.dao.impl.ProductsDao"> <property name="common" ref="common"></property> </bean> <bean id="sdao" class="com.ssh.dao.impl.SalesmanDao"> <property name="common" ref="common"></property> </bean> <bean id="salemService" class="com.ssh.service.impl.SaleManagerService"> <property name="prodao" ref="pdao"></property> <property name="saldao" ref="sdao"></property> </bean> <!-- Action配置 --> <bean name="/pdt" class="com.ssh.action.ProductsManagerAction"> <property name="ss" ref="salemService"></property> </bean> <!-- 事務管理器 --> <bean id="htm" class="org.springframework.orm.hibernate3.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <!-- 定義事務攔截器 --> <bean id="transactionInterceptor" class="org.springframework.transaction.interceptor.TransactionInterceptor"> <property name="transactionManager" ref="htm"></property> <property name="transactionAttributes"> <props> <prop key="insert*">PROPAGATION_REQUIRED</prop> <prop key="update*">PROPAGATION_REQUIRED</prop> <prop key="delete*">PROPAGATION_REQUIRED</prop> <prop key="query*">PROPAGATION_REQUIRED,readOnly</prop> <prop key="get*">PROPAGATION_REQUIRED,readOnly</prop> <prop key="validate*">PROPAGATION_REQUIRED</prop> </props> </property> </bean> <!-- 自動代理 --> <bean id="auto" class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator"> <!-- beanNames --> <property name="beanNames"> <value>*Service</value> </property> <property name="interceptorNames"> <list> <value>transactionInterceptor</value> </list> </property> </bean> </beans><?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="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="configLocation" value="classpath:hibernate.cfg.xml"> </property> </bean> <bean id="template" class="org.springframework.orm.hibernate3.HibernateTemplate"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <bean id="common" class="com.ssh.common.Common"> <property name="hibernateTemplate" ref="template"></property> </bean> <bean id="pdao" class="com.ssh.dao.impl.ProductsDao"> <property name="common" ref="common"></property> </bean> <bean id="sdao" class="com.ssh.dao.impl.SalesmanDao"> <property name="common" ref="common"></property> </bean> <bean id="salemService" class="com.ssh.service.impl.SaleManagerService"> <property name="prodao" ref="pdao"></property> <property name="saldao" ref="sdao"></property> </bean> <!-- Action配置 --> <bean name="/pdt" class="com.ssh.action.ProductsManagerAction"> <property name="ss" ref="salemService"></property> </bean> <!-- 事務管理器 --> <bean id="htm" class="org.springframework.orm.hibernate3.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <!-- 定義事務攔截器 --> <bean id="transactionInterceptor" class="org.springframework.transaction.interceptor.TransactionInterceptor"> <property name="transactionManager" ref="htm"></property> <property name="transactionAttributes"> <props> <prop key="insert*">PROPAGATION_REQUIRED</prop> <prop key="update*">PROPAGATION_REQUIRED</prop> <prop key="delete*">PROPAGATION_REQUIRED</prop> <prop key="query*">PROPAGATION_REQUIRED,readOnly</prop> <prop key="get*">PROPAGATION_REQUIRED,readOnly</prop>

 

以上是Struts1.0的寫法。

applicationContext.xml需要做以下幾件事情: 數據源的配置(可以在hibernate-config.xml配置),Common層，Dao層，Service層，Action層(也可以單獨配置，然後採用Struts的插件plug-In將其添入),事務配置。

 

注意點:

    a.在配置 SessionFactory 時，其屬性configLocation的值爲applicationContext.xml在發佈之後的路徑,若它位於src目錄下，則可以直接使用 classpath:; 若其位於WEB-INF下則爲 /WEB-INF/classes/applicationContext.xml

    b.如果採用的是Struts1，則配置Action Bean時，用name代替id屬性，其值爲struts-config.xml中相應Action的path屬性值。class值爲Action的類路徑，struts-config.xml中type屬性爲DelegatingActionProxy 代理類的路徑

    c.在自動代理配置中beanNames屬性爲Service層Bean組件的id值。

 

 

3.Struts-config.xml

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.3//EN" "http://struts.apache.org/dtds/struts-config_1_3.dtd"> <struts-config> <form-beans> <form-bean name="userForm" type="com.ssh.action.form.UserForm"></form-bean> </form-beans> <global-exceptions /> <global-forwards /> <action-mappings> <action path="/pdt" name="userForm" type="org.springframework.web.struts.DelegatingActionProxy" parameter="pm" scope="request"> <forward name="showDetails" path="/showDetails.jsp"></forward> <forward name="error" path="/Login.html"></forward> </action> </action-mappings> <!-- <controller> <set-property property="processorClass" value="org.springframework.web.struts.DelegatingRequestProcessor"/> </controller> --> <controller processorClass="com.ssh.action.MyRequestProcessor"></controller> <message-resources parameter="com.yourcompany.struts.ApplicationResources" /> </struts-config>

 

Struts大家都很熟悉，在此不作解釋。
