Maven构建Struts2+Hibernate+Spring web项目
软件：
maven：3.3.9，jdk：1.7 ，Struts2：2.3.24.1，Hibernate：4.3.6，Spring：4.2.5，mysql：5.1.34，Junit：4，Myeclipse：2014；
源码下载：https://github.com/fansy1990/ssh_v3
1. 构建Maven工程
1.1 Maven 设置：
选择Maven的本地路径：
Window -》 Preference -> Maven4Myeclipse
修改setting.xml(视情况修改，先可以不修改，如果下载jar包下载有问题时，再改)
<mirror>
<id>nexus-osc</id>
<mirrorOf>*</mirrorOf>
<name>Nexus osc</name>
<url>http://maven.oschina.net/content/groups/public/</url>
</mirror>设置为开源中国的资源库，这样下载快
1.2 JDK设置：
新添加jdk，同时添加 Default VM Arguments: -Dmaven.multiModuleProjectDirectory=$M2_HOME1.3 新建Maven工程
1）File -> New -> Project -> Maven Project
2）选择webapp catalog
3）设置 group id 和artifact id:
建好的工程如下（上面起名改为v3，而非v2）：
2. 添加Web支持
1） 右键工程：Myeclipse -> Project Facets[Capabilities] -> Install Dynamic Web Module ;
不用添加tomcat的lib包到工程classpath中；
添加后的工程如下：
3. 添加Struts2、Hibernate、Spring
3.1 pom.xml:

3.2 web.xml:

<!-- 添加对spring的支持 -->

<!-- 当hibernate+spring配合使用的时候，如果设置了lazy=true,那么在读取数据的时候，当读取了父数据后，
hibernate会自动关闭session，这样，当要使用子数据的时候，系统会抛出lazyinit的错误，
这时就需要使用spring提供的 OpenSessionInView,OpenSessionInView主要是保持Session状态
知道request将全部页面发送到客户端，这样就可以解决延迟加载带来的问题 -->

3.3 添加resource目录（source），并修改输出目录：
拷贝下面的文件到resource目录：
struts.xml:
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC

<constant name="struts.enable.DynamicMethodInvocation" value="true" />
<!--设置编码形式为UTF-8-->
<constant name="struts.i18n.encoding" value="UTF-8"/>
<!-- 添加spring管理 -->
<constant name="struts.objectFactory" value="spring"/>
<!-- 添加test action测试 -->
<package name="test" extends="struts-default" namespace="/test">
<action name="user" class="demo.action.UserAction">
<result>/success.jsp</result>
</action>
</package>
</struts>
applicationContext.xml:

jdbc.properties:(根据实际情况修改)
jdbc.driverClassName=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://localhost:3306/hibernate jdbc.username=root jdbc.password=root
log4j.properties:
log4j.rootLogger=WARN, stdout 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
3.4 把maven jar包添加到lib中：
右键工程-> properties -> myeclipse -> Deployment Assembly
做好上面的步骤后，其工程目录如下：
