参考网上的例子，自己做了个简单的struts2.0+ibatis+spring2.0登陆的例子。
链接：http://blog.csdn.net/jinlong0/archive/2008/01/11/2034732.aspx
1. 新建web工程

点击“finish”。
2. 加入jar包
将下面的jar包加入WEB-INF/lib下
antlr-2.7.2.jar
aopalliance.jar
cglib-2.1.3.jar
commons-collections.jar
commons-dbcp.jar
commons-logging-1.0.4.jar
commons-pool.jar
freemarker-2.3.8.jar
ibatis-2.3.1.710.jar
mysql-connector-java-5.0.4-bin.jar
ognl-2.6.11.jar
oro-2.0.8.jar
spring.jar
struts2-core-2.0.11.1.jar
struts2-spring-plugin-2.0.11.1.jar
xwork-2.0.4.jar
3. 配置web.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" 
    xmlns="http://java.sun.com/xml/ns/j2ee" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee 
    http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
  <welcome-file-list>
    <welcome-file>login.jsp</welcome-file>
  </welcome-file-list>
  <context-param>  
		<param-name>contextConfigLocation</param-name>
		<param-value>/WEB-INF/classes/applicationContext.xml</param-value> 
	</context-param> 
  <listener>
      <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  <filter>
      <filter-name>struts2</filter-name>
      <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
  </filter>
  <filter-mapping>
      <filter-name>struts2</filter-name>
      <url-pattern>/*</url-pattern>
  </filter-mapping>
</web-app>

4. 创建类与类包
结构如下图

5. 映射数据库表Users.java

package org.login.vo;

public class Users {
	private Integer id;
    private String userName;
    private String password;
        
    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public Users() {
        
    }

    public Users(Integer id, String userName, String password) {
        super();
        this.id = id;
        this.userName = userName;
        this.password = password;
    }

}

6. 映射xml（users.xml）

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE sqlMap      
    PUBLIC "-//ibatis.apache.org//DTD SQL Map 2.0//EN"      
    "http://ibatis.apache.org/dtd/sql-map-2.dtd">
<sqlMap namespace="User">
    <typeAlias alias="user" type="org.login.vo.Users"/>
    
    <select id="recordCount" resultClass="int">
		select count(*) as count from users
	</select>
	<select id="firstPage" resultClass="user" parameterClass="user">
		select top $pagesize$ * from users order by id desc
	</select>

	<!--分页排序-->
	<sql id="paginationStart">
		<![CDATA[
		   select * from (select row_.*, rownum rownum_ from (
		  ]]>
	</sql>
	<sql id="paginationEnd">
		<![CDATA[
		   )row_ where rownum<=#end# ) where rownum_>=#start#
		  ]]>
	</sql>

	<select id="otherPage" resultClass="user" parameterClass="map">
        <include refid="paginationStart"/>
        <![CDATA[
            SELECT 
             * 
            FROM 
             users
        ]]>
        <include refid="paginationEnd"/> 
	</select>
	
    <select id="checkUser" parameterClass="user" resultClass="user">
        <![CDATA[
            SELECT id, username, password FROM users WHERE username = #userName# and password = #password#
        ]]>
    </select>
    
    <select id="getUserById" parameterClass="java.lang.Integer" resultClass="user">
        <![CDATA[
            SELECT id, username, password FROM users WHERE id = #id#
        ]]>
    </select>
    
    <select id="getAllUser" resultClass="user" parameterClass="map">
        <![CDATA[
            SELECT id, username, password FROM users limit #start# ,#end#
        ]]>
    </select>
    
    <insert id="insertUser" parameterClass="user">
        <![CDATA[
            INSERT INTO users (username, password) VALUES (#userName#, #password#)
        ]]>
    </insert>
    
    <update id="updateUser" parameterClass="user">
        <![CDATA[
            UPDATE users SET username=#userName#, password=#password# WHERE id=#id#
        ]]>
    </update>
    
    <delete id="deleteUser" parameterClass="java.lang.Integer">
        <![CDATA[
            DELETE FROM users WHERE id = #id#
        ]]>
    </delete>
</sqlMap>

7. 接口及实现
接口IUserDAO.java

package org.login.dao;

import java.util.List;
import org.login.vo.Users;

public interface IUserDAO {
    List<Users> getAllUser();   
    Users getUserById(Integer id);   
    boolean isLogin(Users user);
    boolean insertUser(Users user);
    boolean updateUser(Users user);  
    boolean deleteUser(Integer id);
}

实现UserDAO

package org.login.dao.Impl;

import java.sql.SQLException;
import java.util.List;

import org.login.dao.IUserDAO;
import org.login.vo.Users;
import com.ibatis.sqlmap.client.SqlMapClient;


public class UserDAO implements IUserDAO {

    private SqlMapClient client = null;

    public SqlMapClient getClient() {
        return client;
    }

    public void setClient(SqlMapClient client) {
        this.client = client;
    }

    
    public boolean deleteUser(Integer id) {
        try {
            client.delete("deleteUser", id);
            return true;
        } catch (SQLException e) {
            e.printStackTrace();
        }
        return false;
    }

  
    public List<Users> getAllUser() {
        List<Users> list = null;
        try {
            list =  client.queryForList("getAllUser");
        } catch (SQLException e) {
            e.printStackTrace();
        }
        return list;
    }

   
    public boolean insertUser(Users user) {
        try {
            client.insert("insertUser", user);
            return true;
        } catch (SQLException e) {
            e.printStackTrace();
        }
        return false;
    }

  
    public boolean updateUser(Users user) {
        try {
            client.update("updateUser", user);
            return true;
        } catch (SQLException e) {
            e.printStackTrace();
        }
        return false;
    }

  
    public boolean isLogin(Users user) {
        try {
            Users u = (Users) client.queryForObject("checkUser", user);
            if (u != null) {
                return true;
            }
        } catch (SQLException e) {
            e.printStackTrace();
        }
        return false;
    }

  
    public Users getUserById(Integer id) {
        Users u = null;
        try {
            u = (Users) client.queryForObject("getUserById", id);
        } catch (SQLException e) {
            e.printStackTrace();
        }
        return u;
    }

}

服务层接口IUserService.java

package org.login.service;

import java.util.List;

import org.login.vo.Users;

public interface IUserService {
    
    List<Users> getAllUser();
    
    Users getUserById(Integer id);
    
    boolean isLogin(Users user);
    
    boolean insertUser(Users user);
    
    boolean updateUser(Users user);
    
    boolean deleteUser(Integer id);
}

服务层实现UserService.java

package org.login.service.Impl;

import java.util.List;

import org.login.dao.IUserDAO;
import org.login.service.IUserService;
import org.login.vo.Users;



public class UserService implements IUserService {

    private IUserDAO userDAO = null;
    
    public IUserDAO getUserDAO() {
        return userDAO;
    }

    public void setUserDAO(IUserDAO userDAO) {
        this.userDAO = userDAO;
    }

    
    public boolean deleteUser(Integer id) {
        
        return userDAO.deleteUser(id);
    }

  
    public List<Users> getAllUser() {
        
        return userDAO.getAllUser();
    }

  
    public boolean insertUser(Users user) {
        
        return userDAO.insertUser(user);
    }

   
    public boolean isLogin(Users user) {
        
        return userDAO.isLogin(user);
    }

  
    public boolean updateUser(Users user) {
        
        return userDAO.updateUser(user);
    }

   
    public Users getUserById(Integer id) {
        
        return userDAO.getUserById(id);
    }

}

Struts中Action实现Login.java

package org.login.actions;

import java.util.HashMap;
import java.util.List;
import java.util.Map;

import javax.servlet.http.HttpServletRequest;
import javax.xml.registry.infomodel.User;

import com.opensymphony.xwork2.Preparable;

public class Login extends ActionSupport implements ModelDriven<Users>, Preparable {
    private IUserService userService ; 
    private String id ;
    private int pageIndex=1 ;
	private String pageBar ;
	private List<Users> list;
	private Users user;
    
    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }
    
    public IUserService getUserService() {
        return userService;
    }

    public void setUserService(IUserService userService) {
        this.userService = userService;
    }

	public int getPageIndex() {
		return pageIndex;
	}

	public void setPageIndex(int pageIndex) {
		this.pageIndex = pageIndex;
	}
	

	public String getPageBar() {
		return pageBar;
	}

	public void setPageBar(String pageBar) {
		this.pageBar = pageBar;
	}
	

	public List<Users> getList() {
		return list;
	}

	public void setList(List<Users> list) {
		this.list = list;
	}
	
	public Users getUser() {
		return user;
	}

	public void setUser(Users user) {
		this.user = user;
	}
    
	public void prepare() throws Exception {
		if (id == null || id.length() == 0)
			user = new Users();
		else
			user = getUserService().getUserById(Integer.parseInt(id));
	}
	
    public String execute() throws Exception {
        if (getUserService().isLogin(user)) {
            return SUCCESS;
        }
        return INPUT;
    }
    
    public String save() throws Exception {
        if (getUserService().insertUser(user)) {
            return SUCCESS;
        }
        return ERROR;
    }

    public String edit() {
		return SUCCESS;
	}
    
    public String update() throws Exception {    
        if (getUserService().updateUser(user)) {
                return SUCCESS;
        }    
        return ERROR;
    }
    
    public String delete() throws Exception {
        if (getUserService().deleteUser(Integer.valueOf(id))) {
            return SUCCESS;
        }
        return ERROR;
    }
    
    
    public String findAllUsers() throws Exception {
    	PageUtil page = new PageUtil();	
		int count = getUserService().getCount();
		page.setCurPage(pageIndex);

		Map<String,Integer> pageMap = new HashMap<String,Integer>();
		pageMap.put("start", page.getStart());
		pageMap.put("end", page.getPageSize());
        list = getUserService().getAllUser(pageMap); 
        return SUCCESS;
    }
    
    public Users getModel() {
		return user;
	}



}
