Web项目中加入struts2 的支持
2. 在web.xml中添加配置
<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>*.do</url-pattern>
</filter-mapping>
3. 在src下添加 struts2的配置文件
Web项目中添加spring的支持
2. 在web.xml中添加spring的配置信息
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/classes/applicationContext.xml
</param-value>
</context-param>
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
3. 在src下加入spring的配置文件
在web项目中整合struts2和spring(个人认为是代码最优的一种方式)
l Action由struts2创建
<action name="showname"
class="net.wanggd.mobile_scm.test.action.TestAction">
l struts2中用到的spring中的bean有spring自动注入
1. struts的配置文件default.properties文件由如下配置struts.objectFactory.spring.autoWire = name
2. spring的配置文件中有
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
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/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd" default-autowire="byName" >
整合步骤:
2. Struts.xml中配置的内容的写法和没有引入spring之前的写法一样,不用变
<?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.action.extension" value="do" />
<constant name="struts.devMode" value="false" />
<package name="default" namespace="/" extends="struts-default">
<action name="welcome">
<result>/WEB-INF/jsp/MyJsp.jsp</result>
</action>
<action name="showname"
class="net.wanggd.mobile_scm.test.action.TestAction">
<result name="ret">/WEB-INF/jsp/index2.jsp</result>
</action>
</package>
</struts>
3. Spring的配置文件写法
<?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/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/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd" default-autowire="byName" >
<bean id="testService"
class="net.wanggd.mobile_scm.test.service.TestServiceImpl" >
</bean>
</beans>
Web项目中配置文件在src下面
当部署到tomcat下后,src下面的东西会自动出现在classpath下面
