spring+struts2+ibatis整合

与spring+springmvc+ibatis相比,只需作相应的修改即可完成框架的整合。具体配置如下:

web.xml

<?xml version="1.0" encoding="UTF-8"?><web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"	xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"	id="WebApp_ID" version="2.5">	<display-name>SSI</display-name>	<listener>      <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>    </listener>	<context-param>		<param-name>contextConfigLocation</param-name>		<param-value>classpath:applicationContext.xml</param-value>	</context-param>	<filter>        <filter-name>struts2</filter-name>        <filter-class>            org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter        </filter-class>    </filter>    <filter-mapping>        <filter-name>struts2</filter-name>        <url-pattern>*.action</url-pattern>    </filter-mapping>    </web-app>

applicationContext.xml

<?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:p="http://www.springframework.org/schema/p"xmlns:context="http://www.springframework.org/schema/context"xmlns:mvc="http://www.springframework.org/schema/mvc"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans-3.0.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context-3.0.xsdhttp://www.springframework.org/schema/mvchttp://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd"><context:component-scan base-package="com.qs"/><mvc:annotation-driven/><mvc:default-servlet-handler/><bean id="myDataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">	<property name="driverClassName" value="http://www.mamicode.com/com.mysql.jdbc.Driver"/>	<property name="url" value="http://www.mamicode.com/jdbc:mysql://localhost:3306/test"/>	<property name="username" value="http://www.mamicode.com/root"/>	<property name="password" value="http://www.mamicode.com/123456"/></bean><bean id="sqlMapClient" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">	<property name="configLocation" value="http://www.mamicode.com/classpath:SqlMapConfig.xml"/>	<property name="dataSource" ref="myDataSource"/></bean><bean name="baseAction" class="com.qs.action.BaseAction" scope="prototype"></bean><bean name="userAction" class="com.qs.action.UserAction" scope="prototype"></bean></beans>

 struts.xml

<?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.objectFactory" value="http://www.mamicode.com/spring"/>	<constant name="struts.action.extension" value="http://www.mamicode.com/action"/>	<constant name="struts.devMode" value="http://www.mamicode.com/true" />		<package name="user" extends="struts-default" namespace="/user">		<action name="user_*" class="userAction" method="{1}">			<result name="SUCCESS">/index.jsp</result>		</action>	</package></struts>

 

使用<constant name="struts.objectFactory" value=http://www.mamicode.com/"spring"/> 即将struts交给spring进行管理,需导入struts2-spring-plugin-2.3.16.3.jar

 

 

在整合过程中,针对struts2有如下几点需注意:

1、宜建BaseAction让所有action类继承,BaseAction用来提供一些仅有的属性及方法。

BaseAction

public class BaseAction extends ActionSupport implements SessionAware,ServletRequestAware,ServletResponseAware,ServletContextAware{	/**	 * 	 */	private static final long serialVersionUID = 2861696572454127047L;		private ServletContext context;	private HttpServletRequest request;	private HttpServletResponse response;	private Map<String, Object> session;	@Override	public void setServletContext(ServletContext context) {		this.context=context;	}	@Override	public void setServletResponse(HttpServletResponse response) {		this.response=response;	}	@Override	public void setServletRequest(HttpServletRequest request) {		this.request=request;	}	@Override	public void setSession(Map<String, Object> session) {		this.session=session;	}		public ApplicationContext getApplicationContext(){		return WebApplicationContextUtils.getWebApplicationContext(context);	}		public Object getObject(String beanName){		return getApplicationContext().getBean(beanName);	}}

 2、struts的配置文件命名需符合规范

  struts-default.xml

  struts-plugin.xml

  struts.xml

  struts.properties

  web.xml

  越往后,级别越高,即:前面配置和后面的相同时,后面的配置文件会把前面的覆盖掉。

3、<result>中跳转页面的路径

  <result name="SUCCESS">/index.jsp</result>

  /index.jsp表示的路径为:/AppName/WebContent/index.jsp

 4、struts2与jsp页面的值传递

  传递方式为在action定义类的属性及相应的set方法
