Strut2+Spring整合框架搭建
参考：http://lukuijun.iteye.com/blog/350750
以下为我自己整理的步骤：
Struts2和Spring整合,创建一个web项目TestSS
1、整合struts2
1)导入strut2的jar包:
commons-logging-1.0.4.jar,
freemarker-2.3.8.jar,
ognl-2.6.11.jar,
struts2-core-2.0.12.jar,
xwork-2.06.jar,
javassist-3.11.0.GA.jar,
commons-fileupload-1.2.2.jar
commons-lang-2.5.jar。暂时导入这些jar包，到时候需要再导入。
2)将struts.xml文件放置在TestSS工程的src目录下。
<?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.objectFactory.spring.autoWire" value="name"></constant>
<package name="struts2" extends="struts-default" >
<action name="login" class="com.test.action.LoginAction">
<result name="input">/login.jsp</result>
<result >/success.jsp</result>
</action>
</package>
</struts>
3)在web.xml里面配置struts2用到的核心过滤器。
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
2、整合spring
1)导入spring的jar包:
spring.jar
struts2-core-2.2.3.1.jar
spring-web-2.5.6.jar
spring-core-2.5.6.jar
spring-context-2.5.6.jar
spring-beans-2.5.6.jar
2)将applicationContext.xml文件放置在TestStrut2工程的WEB-INF目录下。
<?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: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/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" default-autowire="byName">
<!-- 构造注入 -->
<!--
<bean id="loginDao" class="com.test.dao.impl.LoginDaoImpl"></bean>
<bean id="loginService" class="com.test.service.impl.LoginServiceImpl">
<property name="loginDao" ref="loginDao"></property>
</bean>
<bean id="loginAction" class="com.test.action.LoginAction" scope="prototype">
<property name="loginService" ref="loginService"></property>
</bean>
-->
<!-- 改成自动装配如下 default-autowire="byName" -->
<bean id="loginDao" class="com.test.dao.impl.LoginDaoImpl"/>
<bean id="loginService" class="com.test.service.impl.LoginServiceImpl"/>
</beans>
3)在web.xml里面配置spring用到的监听器。
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
4)添加struts2-spring整合的插件:struts2-spring-plugin-2.2.3.1.jar,如果不使用这个插件，则需要在struts.xml里面配置:
<constant name="struts.objectFactory" value="org.apache.struts2.spring.StrutsSpringObjectFactory" />
5)可以在web-inf下加入log4j的lib，在web.xml配置如下：
<context-param>
<param-name>webAppRootKey</param-name>
<param-value>TestSS.root</param-value>
</context-param>
<context-param>
<param-name>log4jConfigLocation</param-name>
<param-value>/WEB-INF/log4j.properties</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
</listener>
3、测试struts2和spring整合对不对? 以下代码为项目配置完成后所有代码。
代码如下：
applicationContest.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: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/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" default-autowire="byName"> <!-- 构造注入 --> <!-- <bean id="loginDao" class="com.test.dao.impl.LoginDaoImpl"></bean> <bean id="loginService" class="com.test.service.impl.LoginServiceImpl"> <property name="loginDao" ref="loginDao"></property> </bean> <bean id="loginAction" class="com.test.action.LoginAction" scope="prototype"> <property name="loginService" ref="loginService"></property> </bean> --> <!-- 改成自动装配如下 default-autowire="byName" --> <bean id="loginDao" class="com.test.dao.impl.LoginDaoImpl"/> <bean id="loginService" class="com.test.service.impl.LoginServiceImpl"/> </beans>
log4j中xml的配置
# For JBoss: Avoid to setup Log4J outside $JBOSS_HOME/server/default/deploy/log4j.xml!
# For all other servers: Comment out the Log4J listener in web.xml to activate Log4J.
log4j.rootLogger=INFO, stdout, logfile
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d %p [%c] - %m%n
log4j.appender.logfile=org.apache.log4j.RollingFileAppender
log4j.appender.logfile.File=${TestSS.root}/WEB-INF/petstore.log
log4j.appender.logfile.MaxFileSize=512KB
# Keep three backup files.
log4j.appender.logfile.MaxBackupIndex=3
# Pattern to output: date priority [category] - message
log4j.appender.logfile.layout=org.apache.log4j.PatternLayout
log4j.appender.logfile.layout.ConversionPattern=%d %p [%c] - %m%n

输入用户名和密码，点提交后后台打印出
user----
is valid user
