此次整合的版本是：struts2.1.8 + spring2.5.6 + hibernate3.3.2

一.先整合hibernate和spring：

hibernate所需要jar包：antlr- 2.7.6.jar、commons-collections-3.1.jar、dom4j-1.6.1.jar、hibernate3.jar、 javassist-3.9.0.GA.jar、jta-1.1.jar、slf4j-api-1.5.8.jar、log4j.jar、slf4j- log4j12-1.5.8.jar （slf4j接口以log4j形式實現），因為采用了注解的方式所以還需(annotation3.4的包)：ejb3-persistence.jar、hibernate-annotations.jar、 hibernate-commons-annotations.jar、hibernate-entitymanager.jar、hibernate- validator.jar、jboss-archive-browsing.jar ，采用了c3p0連接池，還需要：c3p0-0.9.1.2.jar

spring所需要jar包：spring.jar、 commons-logging.jar ，spring注解需要：common-annotations.jar ，aop需要：aspectjrt.jar、 aspectjweaver.jar、cglib-nodep-2.1_3.jar

hibernate.cfg.xml配置：

<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE hibernate-configuration PUBLIC

<!-- 每次都驗證連接是否可用 -->
<property name="hibernate.c3p0.validate">true</property>
<mapping class="com.fsj.model.User" />
</session-factory>
</hibernate-configuration>

 applicationContext.xml配置如下：

<?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:context="http://www.springframework.org/schema/context"

<context:component-scan base-package="com.fsj" /><!-- 啟用自動掃描 -->
<!-- 基于hibernate注解的sessionFactory -->
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="configLocation" value="classpath:hibernate.cfg.xml">

</bean>
<!-- 基于hibernate的事務管理器 -->

<property name="sessionFactory" ref="sessionFactory" />
</bean>
<!-- 采用注解形式的聲明式事務管理 -->
<tx:annotation-driven transaction-manager="txManager"/>
</beans>

User類采用hibernate的注解形式：

package com.fsj.model;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import static javax.persistence.GenerationType.IDENTITY;
import javax.persistence.Id;
import javax.persistence.Table;
@Entity
@Table(name = "_user")
public class User implements java.io.Serializable {
private static final long serialVersionUID = -3564872478826196506L;
private Integer uid;
private String uname;
private String upwd;
@Id
@GeneratedValue(strategy = IDENTITY)
@Column(name = "u_id", unique = true, nullable = false)
public Integer getUid() {
return this.uid;
}
public void setUid(Integer UId) {
this.uid = UId;
}
@Column(name = "u_name", length = 20)
public String getUname() {
return this.uname;
}
public void setUname(String UName) {
this.uname = UName;
}
@Column(name = "u_pwd", length = 20)
public String getUpwd() {
return this.upwd;
}
public void setUpwd(String UPwd) {
this.upwd = UPwd;
}
}

DAO層的實現類為：

package com.fsj.dao.impl;
import java.util.List;
import javax.annotation.Resource;
import org.hibernate.SessionFactory;
import org.springframework.orm.hibernate3.HibernateTemplate;
import org.springframework.stereotype.Repository;
import com.fsj.dao.UserDao;
import com.fsj.model.User;
@Repository("userDao")
public class UserDaoImpl implements UserDao {
private HibernateTemplate hibernateTemplate;
@Resource
public void setSessionFactory(SessionFactory sessionFactory)
{
this.hibernateTemplate = new HibernateTemplate(sessionFactory);
}
@SuppressWarnings("unchecked")
public User login(String name, String pwd) {
List<User> users= hibernateTemplate.find("from User where uname=? and upwd=?",new Object[]{name,pwd});
System.out.println(users.size()+"-------------");
return (users==null || users.size()==0)?null:(User)users.get(0);
}
}

 service層的實現類采用事務管理：

package com.fsj.sevice.impl;
import java.util.List;
import javax.annotation.Resource;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Propagation;
import org.springframework.transaction.annotation.Transactional;
import com.fsj.dao.UserDao;
import com.fsj.model.User;
import com.fsj.sevice.UserService;
@Service("userService")
@Transactional(rollbackFor = Exception.class)
public class UserServiceImpl implements UserService {
@Resource
private UserDao userDao;
@Transactional(readOnly = true, propagation = Propagation.NOT_SUPPORTED)
public User login(String name, String pwd) {
return userDao.login(name, pwd);
}
}

junit測試成功后，再加入struts2：

加入包：xwork-core-2.1.6.jar、 struts2-core-2.1.8.jar、ognl-2.7.3.jar、freemarker-2.3.15.jar、commons-io- 1.3.2.jar、commons-fileupload-1.2.1.jar、struts2-spring-plugin-2.1.8.jar

web.xml如下設置：

<?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"

struts.xml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">

<package name="user" namespace="/user" extends="myDefault">

<result name="success">/WEB-INF/user/loginSuccess.jsp</result>
<result name="input">/login.jsp</result>
</action>
</package>
</struts>

 UserAction類：

package com.fsj.web;
import java.util.Map;
import javax.annotation.Resource;
import org.apache.struts2.interceptor.SessionAware;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Controller;
import com.fsj.model.User;
import com.fsj.sevice.UserService;
import com.opensymphony.xwork2.ActionSupport;
@Controller("userAction")@Scope("prototype")
public class UserAction extends ActionSupport implements SessionAware{
private Map<String, Object> session;
private User user;
@Resource
private UserService userService;
public String getResult() {
return result;
}
public String login()
{
User logindUser = userService.login(user.getUname(), user.getUpwd());
if(logindUser==null)
{
addActionError("用戶名或密碼錯誤，請重新輸入。");
return INPUT;
}
session.put("user", logindUser);
return SUCCESS;
}
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
public void setSession(Map<String, Object> session) {
this.session = session;
}
}

與UserAction同一包中建立驗證文件：UserAction-validation.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE validators PUBLIC
"-//OpenSymphony Group//XWork Validator 1.0.2//EN"
"http://www.opensymphony.com/xwork/xwork-validator-1.0.2.dtd">

<field name="user.uname">
<field-validator type="requiredstring">

<field-validator type="regex">
<param name="expression">^[a-zA-Z][a-zA-Z0-9_]{3,14}$</param>
<message>登錄的用戶名必須以字母開始，后面跟字母、數字或_，長度為4-15位</message>
</field-validator>
</field>
<field name="user.upwd">

</field-validator>
<field-validator type="regex">

<message>登錄的密碼可以由字母、數字和! @ # 組成，長度為4-15位</message>
</field-validator>
</field>
</validators>

 login.jsp頁面：

<%@ 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+"/";
