Spring2.5+Struts2+Jpa(Hibernate实现)整合之二

改篇主要编写整合struts2相关的配置文件。

修改web.xml文件，修改后的代码如下：

<?xml version="1.0" encoding="UTF-8"?> <web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <!-- 对Spring进行实例化 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- spirng解决乱码 --> <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> <filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class> <!-- <init-param> <param-name>struts.action.extension</param-name> <param-value>zyg</param-value> </init-param> --> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> </web-app>

在src下创建struts配置文件struts.xml文件，其代码如下：

<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" "http://struts.apache.org/dtds/struts-2.0.dtd"> <struts> <constant name="struts.i18n.encoding" value="UTF-8"/> <constant name="struts.objectFactory" value="spring"/> <constant name="struts.devMode" value="true" /> <constant name="struts.server.browserCache" value="false"/> <constant name="struts.configuration.xml.reload" value="true"/> <constant name="struts.ui.theme" value="simple"/> <!-- Add packages here --> <package name="student" namespace="/student" extends="struts-default"> <global-results> <result name="message">/WEB-INF/pages/message.jsp</result> </global-results> <action name="action_*" class="studentAction" method="{1}"> <result name="list">/WEB-INF/pages/studentlist.jsp</result> <result name="add">/WEB-INF/pages/addStudent.jsp</result> <result name="save">/WEB-INF/pages/message.jsp</result> <result name="edit">/WEB-INF/pages/editStudent.jsp</result> <result name="delResult" type="redirect">action_list.action</result> <result name="editResult" type="redirect">action_list.action</result> </action> </package> </struts>

Spring整合Struts1.3.8需要在struts的配置文件struts-config.xml文件添加如下代码:

<controller> <set-property property="processorClass" value="org.springframework.web.struts .DelegatingRequestProcessor"/> </controller>

上面配置的意思是让spring来代理对struts的请求。

       Spring整合struts2更加简单，连上面的配置都不要，我们加入的struts2-spring-plugin-2.0.11.1.jar已经完成了spring和struts2的整合工作。我们只需要在struts.xml中配置struts的action时将action的class属性设置为spring容器中的bean就可以了。

       Src下applicationContext.xml文件的代码如下：

<?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/> <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalEntityManagerFactoryBean"> <property name="persistenceUnitName" value="zyg_db"></property> </bean> <bean id="txManger" class="org.springframework.orm.jpa.JpaTransactionManager"> <property name="entityManagerFactory" ref="entityManagerFactory"/> </bean> <tx:annotation-driven transaction-manager="txManger"/> <bean id="studentDao" class="com.zyg.ssj.dao.jpa.StudentDaoImpl"/> <bean id="studentService" class="com.zyg.ssj.service.impl.StudentServiceImpl"/> <!-- Spring 管理struts的action --> <bean id="studentAction" class="com.zyg.ssj.web.action.StudentAction"></bean> </beans>

 

至此，该篇完成了Spring与struts2整合相关配置文件的编写。下一篇开始编写整合struts2的bean和action。
