代码：

1.前端页面

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
    <%@ taglib prefix="s" uri="/struts-tags"%>
     <html> 
    	<head>
    		<title>登录</title>
    	</head>
    	<body>
    	   <s:form action="doLogin.action">
    	     <table>
    	       <tr>	       
    	        <s:textfield name="loginName" label="用户名"  /> 
    	       </tr>
    	       <tr>
    	         <s:textfield name="loginPwd" label="密码"  /> 
    	       </tr>
    	       <tr>
    	         <s:submit value="确认"  /> 
    	       </tr>	     
    	     </table>
    	   </s:form>
    		
    	</body>
    </html>

success.jsp

<%@ page language="java" import="java.util.*" pageEncoding="gbk"%>
    <%
    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 'success.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>
        登录成功!
      </body>
    </html>

error.jsp

2.配置文件

applicationContexrt.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"

    	http://www.springframework.org/schema/aop 
    	http://www.springframework.org/schema/aop/spring-aop-2.0.xsd">
    	
    	
    	<bean id="dataSource"
    		class="org.apache.commons.dbcp.BasicDataSource">
    		
    		<property name="driverClassName"
    			value="com.mysql.jdbc.Driver">
    		</property>
    		
    		<property name="url"
    			value="jdbc:mysql://localhost:3306/bookshop">

    	<bean id="sessionFactory"
    		class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
    		
    		<property name="dataSource">
    			<ref bean="dataSource" />
    		</property>
    		
    		<property name="hibernateProperties">
    			<props>
    			    
    				<prop key="hibernate.dialect">

    		</property>
    		<property name="mappingResources">
    			<list>

    		</property>
    	</bean>
    	
    	
    	<bean id="userDAO" class="com.ssh2test1.dao.UserDAOImpl">	
    	  <property name="sessionFactory" ref="sessionFactory"/>
    	</bean>
    	
    	
    	<bean id="userBiz" class="com.ssh2test1.biz.UserBizImpl">
    	 <property name="userDAO" ref="userDAO" />
    	</bean>
    	
    	
    	<bean id="umAction" class="com.ssh2test1.action.UserManagerAction">
    	  <property name="userBiz" ref="userBiz" />
    	</bean>
    </beans>

struts.xml

<?xml version="1.0" encoding="UTF-8" ?>
    <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">
    <struts>  
      <package name="default" extends="struts-default">
         
    	 <action name="doLogin" class="umAction">	
    	    
    	      <result name="error">error.jsp</result>
    	      <result name="success">success.jsp</result>
    	 </action>
      </package>
    </struts>

3.编写数据访问层

UserDAO.java

package com.ssh2test1.dao;
    
    import java.util.List;
    
    import com.ssh2test1.entity.Users;
    
    public interface UserDAO {
      public List search(Users condition);
    }

UserDAOImpl.java

package com.ssh2test1.dao;
    
    import java.sql.SQLException;
    import java.util.List;
    
    import org.hibernate.Criteria;
    import org.hibernate.HibernateException;
    import org.hibernate.Session;
    import org.hibernate.criterion.Restrictions;
    import org.springframework.orm.hibernate3.HibernateCallback;
    import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
    
    import com.ssh2test1.entity.Users;
    
    public class UserDAOImpl extends HibernateDaoSupport implements UserDAO {
    
    	@Override
    	public List search(final Users condition) {
    		// TODO Auto-generated method stub
    		return super.getHibernateTemplate().executeFind(new HibernateCallback() {
    			
    			@Override
    			public Object doInHibernate(Session session) throws HibernateException, SQLException {
    				// TODO Auto-generated method stub
    				Criteria c=session.createCriteria(Users.class);
    				if(condition!=null){
    					if(condition.getLoginName()!=null && !condition.getLoginName().equals("")){
    						c.add(Restrictions.eq("loginName", condition.getLoginName()));
    					}
    					if(condition.getLoginPwd()!=null && !condition.getLoginPwd().equals("")){
    						c.add(Restrictions.eq("loginPwd", condition.getLoginPwd()));
    					}
    				}
    				return c.list();
    			}
    		});
    	}
    
    }

4.编写业务逻辑层

UserBiz.java

package com.ssh2test1.biz;
    
    import java.util.List;
    
    import com.ssh2test1.entity.Users;
    
    public interface UserBiz {
       public List login(Users condition);
    }

UserBizImpl.java

package com.ssh2test1.biz;
    
    import java.util.List;
    
    import com.ssh2test1.dao.UserDAO;
    import com.ssh2test1.entity.Users;
    
    public class UserBizImpl implements UserBiz {
    
    	//使用UserDAO接口声明对象，并添加set方法用于依赖注入
    	UserDAO userDAO;
    	
    	public void setUserDAO(UserDAO userDAO){
    		this.userDAO=userDAO;
    	}
    	public List login(Users condition) {
    		// TODO Auto-generated method stub
    		return userDAO.search(condition);
    	}
    
    }

5.编写实体类及实体映射文件

Users.java

package com.ssh2test1.entity;
    
    import java.io.Serializable;
    
    public class Users implements Serializable {
    	private Integer id;
    	private String loginName;
    	private String loginPwd;
    	private String name;
    	private String address;
    	private String phone;
    	private String mail;
    	private Integer userRoleId;
    	private Integer userStateId;
    	public Users() {
    	}
    	public Users(String loginName, String loginPwd, String name,
    			String address, String phone, String mail, Integer userRoleId,
    			Integer userStateId) {
    		this.loginName = loginName;
    		this.loginPwd = loginPwd;
    		this.name = name;
    		this.address = address;
    		this.phone = phone;
    		this.mail = mail;
    		this.userRoleId = userRoleId;
    		this.userStateId = userStateId;
    	}
    	public Integer getId() {
    		return this.id;
    	}
    
    	public void setId(Integer id) {
    		this.id = id;
    	}
    
    	public String getLoginName() {
    		return this.loginName;
    	}
    
    	public void setLoginName(String loginName) {
    		this.loginName = loginName;
    	}
    
    	public String getLoginPwd() {
    		return this.loginPwd;
    	}
    
    	public void setLoginPwd(String loginPwd) {
    		this.loginPwd = loginPwd;
    	}
    
    	public String getName() {
    		return this.name;
    	}
    
    	public void setName(String name) {
    		this.name = name;
    	}
    
    	public String getAddress() {
    		return this.address;
    	}
    
    	public void setAddress(String address) {
    		this.address = address;
    	}
    
    	public String getPhone() {
    		return this.phone;
    	}
    
    	public void setPhone(String phone) {
    		this.phone = phone;
    	}
    
    	public String getMail() {
    		return this.mail;
    	}
    
    	public void setMail(String mail) {
    		this.mail = mail;
    	}
    
    	public Integer getUserRoleId() {
    		return this.userRoleId;
    	}
    
    	public void setUserRoleId(Integer userRoleId) {
    		this.userRoleId = userRoleId;
    	}
    
    	public Integer getUserStateId() {
    		return this.userStateId;
    	}
    
    	public void setUserStateId(Integer userStateId) {
    		this.userStateId = userStateId;
    	}
    }

Users.hbm.xml

<?xml version="1.0" encoding="utf-8"?>
    <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
    "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
    
    <hibernate-mapping>
        <class name="com.ssh2test1.entity.Users" table="users" catalog="bookshop">
            <id name="id" type="java.lang.Integer">
                <column name="Id" />
                <generator class="native"></generator>
            </id>
            <property name="loginName" type="java.lang.String">
                <column name="LoginName" length="50" />
            </property>
            <property name="loginPwd" type="java.lang.String">
                <column name="LoginPwd" length="16" />
            </property>
            <property name="name" type="java.lang.String">
                <column name="Name" length="16" />
            </property>
            <property name="address" type="java.lang.String">
                <column name="Address" length="16" />
            </property>
            <property name="phone" type="java.lang.String">
                <column name="Phone" length="16" />
            </property>
            <property name="mail" type="java.lang.String">
                <column name="Mail" length="16" />
            </property>
            <property name="userRoleId" type="java.lang.Integer">
                <column name="UserRoleId" />
            </property>
            <property name="userStateId" type="java.lang.Integer">
                <column name="UserStateId" />
            </property>
        </class>
    </hibernate-mapping>

6.编写action控制类

package com.ssh2test1.action;
    
    import java.util.List;
    
    import com.opensymphony.xwork2.ActionSupport;
    import com.ssh2test1.biz.UserBiz;
    import com.ssh2test1.entity.Users;
    
    public class UserManagerAction extends ActionSupport {
    	//定义用于保存用户登录表单参数的两个属性
    	private String loginName;
    	private String loginPwd;
    	public String getLoginName() {
    		return loginName;
    	}
    	public void setLoginName(String loginName) {
    		this.loginName = loginName;
    	}
    	public String getLoginPwd() {
    		return loginPwd;
    	}
    	public void setLoginPwd(String loginPwd) {
    		this.loginPwd = loginPwd;
    	}
    	//使用UserBiz声明一个对象，并添加set方法用于依赖注入
    	UserBiz userBiz;	
    	public void setUserBiz(UserBiz userBiz) {
    		this.userBiz = userBiz;
    	}
    	//重载execute方法用来处理登录请求
    	public String execute() throws Exception {
    		// TODO Auto-generated method stub
    		Users condition=new Users();
    		condition.setLoginName(loginName);
    		condition.setLoginPwd(loginPwd);		
    		List list=userBiz.login(condition);
    		if(list.size()>0){
    			//登录成功，转到success.jsp页面
    			return "success"; 
    		}else{
    			//登录失败，转到error.jsp页面
    			return "error";   
    		}		
    	}
    }
