2、配置beans.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:p="http://www.springframework.org/schema/p"
	xmlns:context="http://www.springframework.org/schema/context" 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-3.1.xsd
	http://www.springframework.org/schema/context
	http://www.springframework.org/schema/context/spring-context-3.1.xsd
	http://www.springframework.org/schema/tx
	http://www.springframework.org/schema/tx/spring-tx-3.1.xsd
	http://www.springframework.org/schema/aop
	http://www.springframework.org/schema/aop/spring-aop-3.1.xsd">

	<!-- 1.配置Spring管理 -->
	<!-- 将bean交由spring管理可以 用<bean></bean>和扫描加注 -->
	<!-- 在xml配置了这个标签后，spring可以自动去扫描base-pack下面或者子包下面的java文件， 如果扫描到有@Component
		@Controller@Service等这些注解的类，则把这些类注册为bean 注意：如果配置了<context:component-scan>那么<context:annotation-config/>
		标签就可以不用再xml中配置了，因为前者包含了后者。另外<context:annotation-config/>还提供了两个子标签 -->
	<!-- 扫描该包及该包下的子包 -->
	<context:component-scan base-package="cn.pp" />

	<!-- 2.配置数据库连接 -->
	<!-- 集成hibernate sessionFactory单例模式 线程安全 创建耗内存 -->
	<!-- 数据库的连接池 在xml中配置和数据库相关联，并用c3p0来配置数据库连接池 -->
	<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"
		destroy-method="close">
		<property name="driverClass" value="com.mysql.jdbc.Driver" />
		<property name="jdbcUrl"
			value="jdbc:mysql://localhost:3306/spring?useUnicode=true&characterEncoding=UTF-8" />
		<property name="user" value="root" />
		<property name="password" value="" />
		<!--初始化时获取的连接数，取值应在minPoolSize与maxPoolSize之间。Default: 3 -->
		<property name="initialPoolSize" value="1" />
		<!--连接池中保留的最小连接数。 -->
		<property name="minPoolSize" value="1" />
		<!--连接池中保留的最大连接数。Default: 15 -->
		<property name="maxPoolSize" value="300" />
		<!--最大空闲时间,60秒内未使用则连接被丢弃。若为0则永不丢弃。Default: 0 -->
		<property name="maxIdleTime" value="60" />
		<!--当连接池中的连接耗尽的时候c3p0一次同时获取的连接数。Default: 3 -->
		<property name="acquireIncrement" value="5" />
		<!--每60秒检查所有连接池中的空闲连接。Default: 0 -->
		<property name="idleConnectionTestPeriod" value="60" />
	</bean>

	<!-- 3.配置SessionFactory -->
	<bean id="sessionFactory" name="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
		<property name="dataSource" ref="dataSource" />
		<!-- 放置hibernate的配置文件 -->
		<property name="mappingResources">
			<list>
				<value>cn/pp/bean/Employee.hbm.xml</value>
			</list>
		</property>
		<property name="hibernateProperties">
			<value>
				hibernate.dialect=org.hibernate.dialect.MySQL5Dialect
				hibernate.hbm2ddl.auto=update
				hibernate.show_sql=true
				hibernate.format_sql=false
			</value>
		</property>
	</bean>

	<!-- 4.配置事务 -->
	<!--hibernate事务管理器配置 -->
	<bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
		<property name="sessionFactory" ref="sessionFactory"></property>
	</bean>
	<!--spring可以用xml和注解来配置事务 声明 -->
	<tx:annotation-driven transaction-manager="transactionManager" />
</beans>

3、Spring实例

import java.util.List;

import cn.pp.params.Employee;

public interface EmployeeIService {
	public boolean save(Employee employee);
	public boolean update(Employee employee);
	public Employee find(String userId);
	public boolean delete(String... userIds);
	public List<Employee> findAll();
}

import java.util.List;
import javax.annotation.Resource;
import org.apache.log4j.Logger;
import org.hibernate.Criteria;
import org.hibernate.SessionFactory;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import cn.pp.params.Employee;
import cn.pp.service.EmployeeIService;

@Service
@Transactional
public class EmployeeServiceImpl implements EmployeeIService {
	private static Logger logger = Logger.getLogger(Employee.class);
	@Resource(name="sessionFactory")
	SessionFactory factory;

	@Override
	public boolean save(Employee employee) {
		try {
			factory.getCurrentSession().save(employee);
		} catch (Exception e) {
			logger.error(e.getMessage());
			return false;
		}
		return true;
	}

	@Override
	public boolean update(Employee employee) {
		try {
			factory.getCurrentSession().update(employee);
		} catch (Exception e) {
			logger.error(e.getMessage());
			return false;
		}
		return true;
	}

	//@Transactional(propagation=Propagation.NOT_SUPPORTED)
	@Override
	public Employee find(String userId) {
		try {
			return (Employee)factory.getCurrentSession().get(Employee.class,userId);
		} catch (Exception e) {
			logger.error(e.getMessage());
		}
		return null;
	}

	@Override
	public boolean delete(String... userIds) {
		try {
			for (String userId : userIds) {
				Employee employee=(Employee)factory.getCurrentSession().load(Employee.class,userId);
				factory.getCurrentSession().delete(employee);
			}
		} catch (Exception e) {
			logger.error(e.getMessage());
			return false;
		}
		return true;
	}

	@SuppressWarnings("unchecked")
	//@Transactional(propagation=Propagation.NOT_SUPPORTED)
	@Override
	public List<Employee> findAll() {
		try {
			//return factory.getCurrentSession().createQuery("from Employee").list();
			Criteria criteria=factory.getCurrentSession().createCriteria(Employee.class);
			return criteria.list();
		} catch (Exception e) {
			logger.error(e.getMessage());
		}
		return null;
	}

}

数据库表映射文件

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
	<class name="cn.pp.params.Employee" table="EMPLOYEE"  lazy="true">
		<id name="userId" column="USER_ID" type="java.lang.String">
			<generator class="uuid" />
		</id>
		<property name="userName" column="USER_NAME" type="java.lang.String" />
		<property name="address" column="ADDRESS" type="java.lang.String" />
		<property name="birthday" column="BIRTHDAY" type="java.util.Date" />
	</class>
</hibernate-mapping>

测试用例：

import java.util.Calendar;
import java.util.Date;
import java.util.GregorianCalendar;
import java.util.List;
import org.junit.BeforeClass;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import cn.pp.params.Employee;
import cn.pp.service.EmployeeIService;

public class EmployeeIServiceTest {

	private static EmployeeIService employeeIService;

	@BeforeClass
	public static void initContext() {
		ApplicationContext context = new ClassPathXmlApplicationContext("beans.xml");
		employeeIService = (EmployeeIService) context.getBean("employeeServiceImpl");
	}

	@Test
	public void testSave() {
		Employee e=new Employee();
		e.setUserName("杰克");
		e.setAddress("北京");
		Calendar c = new GregorianCalendar(1991, 5, 5, 0,0,0);
		Date date=c.getTime();
		e.setBirthday(date);
		employeeIService.save(e);
	}

	@Test
	public void testUpdate() {
		Employee e=employeeIService.find("4028826a507f660001507f6601620000");
		e.setUserName("螺丝");
		employeeIService.update(e);
	}

	@Test
	public void testFind() {
		Employee e=employeeIService.find("4028826a507f660001507f6601620000");
		System.out.println(e.getUserName());
	}

	@Test
	public void testDelete() {
		employeeIService.delete("4028826a507f660001507f6601620000");
	}

	@Test
	public void testFindAll() {
		List<Employee> list=employeeIService.findAll();
		for(Employee e : list){
			System.out.println(e.getUserName());
			employeeIService.delete(e.getUserId());
		}
	}
}

4、Struts配置：

<struts>
	<!-- 指定默认 编码集，作用于HttpServletRequest 的setCharacterEncoding方法和freemarker velocity的输出 -->
    <constant name="struts.118n.encoding" value="UTF-8"></constant>
    <!-- 该属性用于指定Struts2请求处理的后缀，默认为.action 可以处理所有后缀是.action的处理，如果
   		   需要指定多个请求处理后缀，后缀之间用逗号隔开 -->
    <constant name="struts.action.extension" value="do,action"></constant>
    <!-- 将struts的action交由spring管理  不在由struts的工厂介入 -->
    <constant name="struts.objectFactory" value="spring" /> 

    <package name="employeePackage" namespace="/pg" extends="struts-default" >
    	<action name="employee_*" class="cn.actions.EmployeeAction" method="{1}">
    		<result name="message">/WEB-INF/message.jsp</result>
    		<result name="list">/WEB-INF/list.jsp</result>
    	</action>
    </package>
</struts> 

测试实例：

action:

// spring 默认scope 是单例模式    @Scope("prototype") 表示每次接收一个请求创建一个Action对象
@Controller @Scope("prototype")
public class EmployeeAction {
	@Resource EmployeeIService employeeIService;
	private String message;
	private HttpServletRequest request;
	private ServletContext context;
	private Employee employee;

	public EmployeeAction(){
		request=ServletActionContext.getRequest();
		context=ServletActionContext.getServletContext();
	}
	public String list(){
		List<Employee> list=employeeIService.findAll();
		request.setAttribute("list", list);
		return "list";
	}
	public String add(){
		if(employee!=null){
			employeeIService.save(employee);
		}else{
			setMessage("部分人员信息为空！");
			return "message";
		}
		setMessage("添加成功");
		return "message";
	}
	public String getMessage() {
		return message;
	}
	public void setMessage(String message) {
		this.message = message;
	}
	public Employee getEmployee() {
		return employee;
	}
	public void setEmployee(Employee employee) {
		this.employee = employee;
	}
}

package cn.pp.params;

import java.util.Date;

public class Employee {
	private String userId;
	private String userName;
	private String address;
	private Date birthday;
	public String getUserId() {
		return userId;
	}
	public void setUserId(String userId) {
		this.userId = userId;
	}
	public String getUserName() {
		return userName;
	}
	public void setUserName(String userName) {
		this.userName = userName;
	}
	public String getAddress() {
		return address;
	}
	public void setAddress(String address) {
		this.address = address;
	}
	public Date getBirthday() {
		return birthday;
	}
	public void setBirthday(Date birthday) {
		this.birthday = birthday;
	}

}
