本文使用Struts+iBatis+Spring三层框架开实现对user表的CRUD。

分层如下：

iBatis配置文件（sqlMapConfig.xml）：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE sqlMapConfig      
    PUBLIC "-//ibatis.apache.org//DTD SQL Map Config 2.0//EN"      
    "http://ibatis.apache.org/dtd/sql-map-config-2.dtd">
<sqlMapConfig>

    <settings cacheModelsEnabled="true" enhancementEnabled="true"
        lazyLoadingEnabled="true" errorTracingEnabled="true" maxRequests="32"
        maxSessions="10" maxTransactions="5" useStatementNamespaces="false" />

    <sqlMap resource="com/tiantian/ibatis/model/user.xml" />
    
</sqlMapConfig>

struts.xml：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
    "http://struts.apache.org/dtds/struts-2.3.dtd">

<struts>

        <!-- 注册User action -->
        <action name="registerUser" class="registerUserAction">

        <!-- 删除User action -->
        <action name="deleteUser" class="deleteUserAction">
        </action>
        <!-- 更新User action -->
        <action name="updateUser" class="updateUserAction">
        </action>
        <!-- 查询所有User action -->
        <action name="findAllUsers" class="findAllUsersAction">
        </action>
        <!-- 查询指定id的User action -->
        <action name="findUserById" class="findUserByIdAction">
        </action>
        <!-- 模糊查询User action -->
        <action name="findUsersBykeyword" class="findUsersBykeywordAction">
        </action>
        
    </package>
    
</struts>

user.xml配置文件：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE sqlMap      
    PUBLIC "-//ibatis.apache.org//DTD SQL Map 2.0//EN"

    <typeAlias alias="UserAlias" type="com.tiantian.ibatis.model.User"/>
    
    <!-- 配置表和实体Bean之间的映射关系 -->  
    <resultMap id="userMap" class="com.tiantian.ibatis.model.User">  
        <result property="id" column="id"/>
        <result property="username" column="username"/>
        <result property="password" column="password"/>
        <result property="age" column="age"/>
    </resultMap>
    <!-- 添加数据 -->
    <insert id="registerUser" parameterClass="UserAlias">
        INSERT INTO user VALUES (NULL, #username#, #password#, #age#);
    </insert>
    <!-- 删除指定id的数据 -->
    <delete id="deleteUser" parameterClass="UserAlias">
        DELETE FROM user WHERE id = #id#;
    </delete>
    <!-- 修改指定id的数据 -->
    <update id="updateUser" parameterClass="UserAlias">
        UPDATE user 
        SET username = #username#, password = #password#, age = #age#
        WHERE id = #id#;
    </update>
    <!-- 查询所有User信息 -->
    <select id="findAllUsers" resultMap="userMap">
        SELECT * FROM user;
    </select>
    <!-- 查询指定id的User信息 -->
    <select id="findUserById" resultMap="userMap">
        SELECT * FROM user WHERE id = #id#;
    </select>
    <!-- 模糊查询 -->
    <select id="findUsersByKeyword" resultMap="userMap">
        SELECT * FROM user WHERE username LIKE '%$keyword$%';
    </select>
    
</sqlMap>

DAO接口：

/**
 * @author wangjie
 * @version 创建时间：2013-3-1 下午5:44:21
 */
public interface UserDao {
    public void registerUser(User user);
    public boolean deleteUser(User user);
    public boolean updateUser(User user);
    public List<User> findAllUsers();
    public User findUserById(User user);
    public List<User> findUsersByKeyword(String keyword);
}

DAO实现类（执行各个Action所需的数据库查询操作）：

package com.tiantian.ibatis.dao.impl;

import java.util.List;

import org.springframework.orm.ibatis.support.SqlMapClientDaoSupport;

import com.tiantian.ibatis.dao.UserDao;
import com.tiantian.ibatis.model.User;

/**
 * @author wangjie
 * @version 创建时间：2013-3-1 下午6:09:53
 */
public class UserDaoImpl extends SqlMapClientDaoSupport implements UserDao{

    public void registerUser(User user) {
        getSqlMapClientTemplate().insert("registerUser", user);
    }

    public boolean deleteUser(User user) {
        boolean result = false;
        int effectedRow = getSqlMapClientTemplate().delete("deleteUser", user);
        System.out.println("delete effectedRow: " + effectedRow);
        result = effectedRow > 0 ? true : false;
        return result;
    }

    public boolean updateUser(User user) {
        boolean result = false;
        int effectedRow = getSqlMapClientTemplate().update("updateUser", user);
        System.out.println("update effectedRow: " + effectedRow);
        result = effectedRow > 0 ? true : false;
        return result;
    }

    public List<User> findAllUsers() {
        return (List<User>)getSqlMapClientTemplate().queryForList("findAllUsers");
    }

    public User findUserById(User user) {
        return (User) getSqlMapClientTemplate().queryForObject("findUserById", user);
    }

    public List<User> findUsersByKeyword(String keyword) {
        return (List<User>)getSqlMapClientTemplate().queryForList("findUsersByKeyword", keyword);
    }
    
    
}

Action类（以RegisterUserAction为例）：

package com.tiantian.ibatis.action.user;

import com.opensymphony.xwork2.ActionSupport;
import com.tiantian.ibatis.model.User;
import com.tiantian.ibatis.service.UserService;
import com.tiantian.ibatis.service.impl.UserServiceImpl;

/**
 * @author wangjie
 * @version 创建时间：2013-3-2 下午11:26:18
 */
public class RegisterUserAction extends ActionSupport{
    private UserService userService;
    private User user;
    
    public User getUser() {
        return user;
    }

    public void setUser(User user) {
        this.user = user;
    }
    
    public UserService getUserService() {
        return userService;
    }

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

    @Override
    public String execute() throws Exception {
        userService.registerUser(user);
        System.out.println("数据已经插入");
        return null;
    }
}
