1、新建一个web工程（这个就不说了）

2、添加Struts2.3

把Struts开发所需的jar复制到工程的lib文件中。开发struts必须包如下：

3、创建action类

声明：整个示例只有一个简单的用户登录。

本例中的action类名为 LoginAction，该类中的代码如下：

package com.riyun.action;     
    
     import com.opensymphony.xwork2.ActionSupport;  
     public class LoginAction extends ActionSupport{  
           
         private static final long serialVersionUID = 1L;  
              
        private String userName;  
    
        private String passWord;  
          
    
         public String getUserName() {  
    
             return userName;  
    
         }  
    
         public String getPassWord() {  
    
             return passWord;  
    
         }  
    
        public void setUserName(String userName) {  
    
            this.userName = userName;  
    
        }  
    
        public void setPassWord(String passWord) {  
    
             this.passWord = passWord;  
    
        }  
           
    
         public String   execute() throws Exception{  
    
            if(userName.equals("riyun")&&passWord.equals("123")){  
    
                   return SUCCESS;  
    
               }else{  
    
                    return ERROR;  
    
                }

至于该类为什么继承ActionSupport，相信网上讲述Struts1.X与Struts2.X的文章已经很多了，这里就不罗嗦了。

4、修改项目中的index.jsp代码，修改后的index.jsp代码如下：

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
    <%@taglib prefix="s" uri="/struts-tags" %>
    <%
    String path = request.getContextPath();
    String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
    %>
    
    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
    <html>
      <head>
        <base href="<%=basePath%>">
        
        <title>My JSP 'index.jsp' starting page</title>
    	<meta http-equiv="pragma" content="no-cache">
    	<meta http-equiv="cache-control" content="no-cache">
    	<meta http-equiv="expires" content="0">    
    	<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
    	<meta http-equiv="description" content="This is my page">
    	
      </head>
      
      <body>
        <s:form action="login">
        	<s:textfield name="userName" label="用户名" key="user"></s:textfield>
        	<s:password  name="passWord" label="密码" key="password"></s:password>
        	<s:submit key="login" value="提交"></s:submit>
        </s:form>
      </body>
    </html>

新建两个success.jsp、error.jsp页面。后面action处理结果跳转有用，如果登陆成功则跳转到success.jsp，反之则跳转到error.jsp！

5、 新建一个以struts.xml为名的xml文件

文件中的代码如下：

<?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>  
                  
           
         <package name="riyun" extends="struts-default">  
            <action name="login" class="com.riyun.action.LoginAction">  
                  
                <result name="success">/success.jsp</result>  
                <result name="error">/error.jsp</result>  
            </action>  
        </package>  
      </struts>

6、在web.xml中添加struts拦截器。

Web.xml的代码如下：

至此Struts2.3整合成功，接下来继续整合Spring3.2。

7、导入所需spring的jar包如下;

![20140510123136238.jpg][]

对于Spring的jar包没有研究过，所以我这里把spring所有的jar都复制到了lib目录中去了。另外还需要导入struts2-spring-plugin-2.3.4.1.jar包。

8、在web-inf目录中新建一个applicationContext.xml为名的xml文件（该文件与web.xml是在同一级目录）

该applicationContext.xml文件中的代码如下：

<?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" 
    "http://www.springframework.org/dtd/spring-beans.dtd">
    <beans>
    	<bean id="userDao" class="com.riyun.daoImpl.UserDaoImpl">  </bean>  
    	<bean id="login" class="com.riyun.action.LoginAction">  
      	 	<property name="userDao" ref="userDao" />  
    	</bean>  
    </beans>

9、修改struts.xml文件，修改后的struts.xml文件中的代码如下

<?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.objectFactory" value="spring"></constant>  
         
         <package name="riyun" extends="struts-default">
         	<action name="login" class="com.riyun.action.LoginAction">
         		
         		<result name="success">/success.jsp</result>
         		<result name="error">/error.jsp</result>
         	</action>
         </package>
      </struts>

10、修改web.xml文件，修改后的web.xml文件中的代码如下：

<?xml version="1.0" encoding="UTF-8"?>
    <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee  
      http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
      
      	
     	 <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>  
    	 
    	<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>
    	
    	
    	<welcome-file-list>
    	    <welcome-file>index.jsp</welcome-file>
    	</welcome-file-list>
    	
     </web-app>

ok，到此为此Struts2.3整合Spring3.2就可以了。那实际项目中不可能不跟数据库打交道。常见的dao层用的是hibernate。但其实还有一些跟hibernate功能相似而且相对于hibernate来说配置更简单的dao层应用可以供我们选择。这里我就选用了JDBC。利用JDBC作为dao层的应用，每个dao层都要继承JDBCSupport类。

11、添加dao层，添加UserDao接口、添加UserDaoImpl实现接口类

UserDao接口的代码如下：

package com.riyun.dao;
    
    public interface UserDao {
    	
    	/*用户登录
    	 * pram:userName,passWord
    	 * return:boolean
    	 */
    	public boolean login(String userName,String passWord);
    
    }

UserDaoImpl实现接口类的代码如下：

package com.riyun.daoImpl;
    
    import java.util.Map;
    
    
    import org.springframework.dao.EmptyResultDataAccessException;
    import org.springframework.jdbc.core.support.JdbcDaoSupport;
    
    import com.riyun.dao.UserDao;
    
    public class UserDaoImpl extends JdbcDaoSupport implements UserDao{
    
    	//用户登录
    	public boolean login(String userName, String passWord) {
    		// TODO Auto-generated method stub
    		String sql="select job,ename from emp where ename=?";
    		Map map=this.getJdbcTemplate().queryForMap(sql, new Object[] {userName});
    		try{
    			String pass=(String) map.get("job");
    			if(passWord.equals(pass)){			
    				return true;
    			}else{
    				return false;
    			}
    		}catch(EmptyResultDataAccessException e){
    			e.printStackTrace();
    			return false;
    		}		
    	}
    }

12、修改LoginAction类的代码，修改后的代码如下：

package com.riyun.action;
    
    import org.apache.log4j.Logger;
    
    import com.opensymphony.xwork2.ActionSupport;
    import com.riyun.dao.UserDao;
    
    public class LoginAction extends ActionSupport{
    	
    	private static final long serialVersionUID = 1L;
    	
    		
    	private UserDao userDao;
    	private String userName;
    	private String passWord;
    	
    	public UserDao getUserDao() {
    		return userDao;
    	}
    	public void setUserDao(UserDao userDao) {
    		this.userDao = userDao;
    	}
    
    	public String getUserName() {
    		return userName;
    	}
    	public String getPassWord() {
    		return passWord;
    	}
    	public void setUserName(String userName) {
    		this.userName = userName;
    	}
    	public void setPassWord(String passWord) {
    		this.passWord = passWord;
    	}
    	
    	
    	public String   execute() throws Exception{
    		if(userDao.login(userName, passWord)){
    			return SUCCESS;
    		}else{
    			return ERROR;
    		}
    	}
    	
    }

13、修改applicationContext.xml文件，修改后的文件代码如下：

<?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" 
    "http://www.springframework.org/dtd/spring-beans.dtd">
    <beans>
    	<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"  destroy-method="close" dependency-check="none">
    		    <property name="driverClass">
    		        <value>oracle.jdbc.driver.OracleDriver</value>
    		    </property>
    		    <property name="jdbcUrl">
    		        <value>jdbc:oracle:thin:@localhost:1521:orcl</value>
    		    </property>
    		    <property name="user">
    		        <value>scott</value>
    		    </property>
    		    <property name="password">
    		        <value>123</value>
    		    </property>
    		    
    	</bean>
    	<bean id="transactionManager"  class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    		<property name="dataSource">
    			<ref local="dataSource" />
    		</property>
    	</bean>
    	<bean id="txManager" abstract="true"
    		class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
    		<property name="transactionManager" ref="transactionManager" />
    		<property name="transactionAttributes">
    			<props>
    				<prop key="add*">
    					PROPAGATION_REQUIRED,-DataAccessException
    				</prop>
    				<prop key="save*">
    					PROPAGATION_REQUIRED,-DataAccessException
    				</prop>
    				<prop key="edit*">
    					PROPAGATION_REQUIRED,-DataAccessException
    				</prop>
    				<prop key="update*">
    					PROPAGATION_REQUIRED,-DataAccessException
    				</prop>
    				<prop key="del*">
    					PROPAGATION_REQUIRED,-DataAccessException
    				</prop>
    				<prop key="handle*">
    					PROPAGATION_REQUIRED,-DataAccessException
    				</prop>
    				<prop key="notify*">
    					PROPAGATION_REQUIRED,-DataAccessException
    				</prop>
    				<prop key="get*">PROPAGATION_REQUIRED,readOnly</prop>
    				<prop key="query*">PROPAGATION_REQUIRED,readOnly,-DataAccessException</prop>
    				<prop key="find*">PROPAGATION_REQUIRED,readOnly</prop>
    				<prop key="is*">PROPAGATION_REQUIRED,readOnly</prop>
    			</props>
    		</property>
    	</bean>
    	
    	<bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
       		<constructor-arg ref="dataSource" />
    	</bean>
    	<bean id="userDao" class="com.riyun.daoImpl.UserDaoImpl">  
              <property name="jdbcTemplate" ref="jdbcTemplate"></property>
    	</bean>  
    	<bean id="login" class="com.riyun.action.LoginAction">  
      	 	<property name="userDao" ref="userDao" />  
    	</bean>  
    </beans>

至此整个例子ok了。  
在dao层连接数据库的时候还需要导入各个数据库所必须的jar包以及c3p0-0.9.1.2.jar这样的包。

总结：整合过程中 碰到许许多多的问题，相信大家看我这篇文章也会碰到许许多多不一样的问题，但是有问题不可怕，我们要做的就是分析问题的原因。我在整合过程碰到最多的问题就是classnotfound类的问题，其实这类的问题就是没有导入相关jar包导致的错误或者jar冲突导致的。
