1、准备Jar包：
struts2、hibernate、spring所需jar包struts-core-2.x.x.jar
----struts核心包 xwork-core-2.x.x.jarognl-2.6.x.jar
----对象导航语言 freemarker-2.3.x.jar
------struts2的ui标签的模板使用commons-fileupload-1.2.x.jar
----文件上传组件 2.1.6版本后需加入此文件struts-spring-plugin-2.x.x.jar
---用于struts2继承spring的插件hibernate核心安装包下的（下载路径：http://www.hibernate.org/
，点击Hibernate Core 右边的download） hibernate2.jarlibytecodehibernate-cglib-repack-2.1_3.jarlib
equired*.jarhibernate安装包下的（下载路径：http://www.hibernate.org/;点击Hibernate
Annotations 右边的下载） hibernate-annotations.jarlibejb3-persistence.jar、hibernate-commons-annotations.jarhibernate针对JPA的实现包（下载路径：http://www.hibernate.org/
，点击Hibernate Entitymanager右边下载） hibernate-entitymanager.jarlib estlog4j.jar、
slf4j-log4j12.jarspring安装包下的distspring.jarlibc3p0c3p0-0.9.1.2.jarlibaspectiaspectjweaver.jaraspectjrt.jarlibcolibcglib-nodep-2.1_3.jarlibj2eecommon-annotations.jarvliblog4jlog4j-1.2.15.jarlibjakarta-commonscommons_loggin.jar数据库驱动包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

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;
}
