首先我们需要导入所有需要使用的包的核心依赖：

<!-- 加入servlet的核心依赖 -->
	<dependency>
	    <groupId>javax.servlet</groupId>
	    <artifactId>javax.servlet-api</artifactId>
	    <version>4.0.0-b07</version>
	    <scope>provided</scope>
	</dependency>
    
    <!-- 加入hibernate核心库 -->
    <dependency>
	    <groupId>org.hibernate</groupId>
	    <artifactId>hibernate-core</artifactId>
	    <version>5.2.10.Final</version>
	</dependency>
	
	
	<!-- 引入Spring核心库 -->
	<dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context</artifactId>
        <version>4.3.10.RELEASE</version>
    </dependency>
	
	 <!-- MySQL  -->
    <dependency>
	    <groupId>mysql</groupId>
	    <artifactId>mysql-connector-java</artifactId>
	    <version>5.1.43</version>
	</dependency>

	<!-- 引入c3p0数据库连接池 -->
	<dependency>
	    <groupId>com.mchange</groupId>
	    <artifactId>c3p0</artifactId>
	    <version>0.9.5.2</version>
	</dependency>

	<!-- Spring整合Hibernate依赖 -->
	<dependency>
	    <groupId>org.springframework</groupId>
	    <artifactId>spring-orm</artifactId>
	    <version>4.3.10.RELEASE</version>
	</dependency>
	
	<!-- spring 的AspectJ依赖，解析事务切点 -->
	<dependency>
	    <groupId>org.springframework</groupId>
	    <artifactId>spring-aspects</artifactId>
	    <version>4.3.10.RELEASE</version>
	</dependency>
	
	
	<!-- 引入struts2依赖 -->
	<dependency>
	    <groupId>org.apache.struts</groupId>
	    <artifactId>struts2-core</artifactId>
	    <version>2.3.33</version>
	</dependency>
	
	<!-- struts2整合Spring的整合包 -->
	<dependency>
	    <groupId>org.apache.struts</groupId>
	    <artifactId>struts2-spring-plugin</artifactId>
	    <version>2.5.12</version>
	</dependency>
	
	<!-- 日志记录核心 -->
	<dependency>
	    <groupId>org.apache.logging.log4j</groupId>
	    <artifactId>log4j-core</artifactId>
	    <version>2.8.2</version>
	</dependency>

二、在web.xml的配置中添加struts的过滤配置和一个监听器、加载器

<web-app>
	<!-- 加载spring的配置文件 -->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:applicationContext.xml</param-value>
	</context-param>
	
	<!-- struts的过滤配置 -->
	<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>/*</url-pattern>
	</filter-mapping>
	  <!-- spring工作监听 -->
	<listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
	  
</web-app>

三、写一个测试的Action（测试struts和spring整合是否成功）。

public class TestAction extends ActionSupport{
	//简单的输出测试就可以了
	public void test(){
		System.out.println("测试成功！");
	}
	
}

四、在resources文件夹下创建struts和spring-action的配置文件和spring-core的配置文件

<struts>
    	<package name="default" namespace="/" extends="struts-default">
    	    <!-- 属性class的只改为spring建的action的id或者name -->
    		<action name="testAction_*" class="testAction" method="{1}">
    			
    		</action>

    	</package>
    </struts>

<?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.xsd">
    

    //spring创建TestAction
	<bean id="testAction" class="com.xb.action.TestAction" scope="prototype">
		
	</bean>
</beans>

<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns:tx="http://www.springframework.org/schema/tx"
	xmlns:aop="http://www.springframework.org/schema/aop"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
						http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd
						http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd">
	

    <!-- 数据库连接使用c3p0数据库连接池 -->
	<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
		<property name="jdbcUrl" value="jdbc:mysql://localhost:3306/test"></property>
		<property name="user" value="root"></property>
		<property name="password" value="123456"></property>
		<property name="maxPoolSize" value="10"></property>
		<property name="initialPoolSize" value="3"></property>
		<property name="driverClass" value="com.mysql.jdbc.Driver"></property>
	</bean>
	<!-- session工厂配置 -->
	<bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
		<property name="dataSource" ref="dataSource"></property>
		<property name="mappingLocations" value="classpath:com/xb/entity/*.hbm.xml"></property>
		<property name="hibernateProperties">
			<props>
				<prop key="hibernate.show_sql">true</prop>
				<prop key="hibernate.format_sql">true</prop>
				<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
			</props>
		</property>
	</bean>

	<!--事务管理配置 -->
	<bean id="transactionManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager">
		<property name="sessionFactory" ref="sessionFactory"></property>
	</bean>
	
	
	<!-- 切面过滤 -->
	<tx:advice id="txAdvice">
		<tx:attributes>
			<tx:method name="add*" propagation="REQUIRED"/>
			<tx:method name="update*" propagation="REQUIRED"/>
			<tx:method name="delete*" propagation="REQUIRED"/>
			<tx:method name="*" read-only="true"/>
		</tx:attributes>
	</tx:advice>
	<!-- 切面配置 -->
	<aop:config>
		<aop:pointcut expression="execution(* com.xb.biz.impl.*.*(..))" id="pointcut"/>
		<aop:advisor advice-ref="txAdvice" pointcut-ref="pointcut"/>
	</aop:config>
	
	
</beans>

在这时候开启服务访问测试方法测试！！！

五、创建dao包（数据层）和biz包（业务层）在两个包下分别写出对应的接口。接下来在创建对应的实现类的文件夹写出实现类.......

public class UserDaoImpl implements UserDao{//dao层的实现类
	//spring 自动生成对象
	private SessionFactory factory;
	
	public void setFactory(SessionFactory factory) {
		this.factory = factory;
	}
	
	public void addUser(User user) {
		//通过session工厂获取当前session保存对象
		factory.getCurrentSession().save(user);
	}

}

public class UserBizImpl implements UserBiz{//biz层实现类
    //spring自动生成对象实例
	private UserDao userDao;

	public void setUserDao(UserDao userDao) {
		this.userDao = userDao;
	}
	
	public void addUser(User user) {
        //调用dao层方法
		userDao.addUser(user);
	}

}

两个接口比较简单就不详细说了。

六、两个spring配置文件------dao和biz的配置

<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.xsd">

	<!-- dao层配置 -->
	<bean id="userDao" class="com.xb.dao.impl.UserDaoImpl">
		<property name="factory" ref="sessionFactory"></property>
	</bean>
	
</beans>

<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.xsd">

	
	<bean id="userBiz" class="com.xb.biz.impl.UserBizImpl">
		<property name="userDao" ref="userDao"></property>
	</bean>
	
</beans>

注意：在配置biz的时候应该想到事务的管理，所以要到spring核心配置文件中配置
