一、新建工程，添加ibatis、spring和struts的jars；

二、数据库设计.

mysql数据库：

use ibatis;
drop table if exists user;

create table if not exists  user(
       ID tinyint primary key auto_increment,
       LOGIN_NAME varchar(10) not null,
       PASS_WORD varchar(15) not null,       
       QX varchar(10) default 'guest' not null ,
       MEMO text              
      )
type=innodb
comment="user info";

insert into user(LOGIN_NAME,PASS_WORD,QX) values('leh','888','admin');
insert into user(LOGIN_NAME,PASS_WORD) values('lek','888');

commit;

数据源的配置

1）、配置文件db.properties （位置：resources/properties/db.properties，这里resources和src是一类文件）

driver=com.mysql.jdbc.Driver
url=jdbc\:mysql\://localhost\:3306/ibatis
username=root
password=54321

2）、注册数据源到spring

!-- spring load dataSource configuration property file -->
<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<list>
<value>properties/database.properties</value>
</list>
</property>
</bean>

<!-- dataSource -->
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="${driver}" />
<property name="url" value="${url}" />
<property name="username" value="${username}" />
<property name="password" value="${password}" />
</bean>

三、POJO类.

本例是User实例类：

package com.leadtone.ibatis.domain;

import java.io.Serializable;

public class User implements Serializable{

private int id;
private String name;
private String password;
private String qx;
private String memo;

public int getId() {
return id;
}
               /**
 *setter和getter方法省略
           */

四、pojo类配置文件编写

本例是User.xml:(位置：com.leadtone.sqlmap.User.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="com.leadtone.ibatis.domain.User"/>  

    <resultMap class="user" id="UserResult">  
        <result property="id" column="ID"/>      
        <result property="name" column="LOGIN_NAME"/>    
        <result property="password" column="PASS_WORD"/>     
        <result property="qx" column="QX"/>      
        <result property="memo" column="MEMO"/>      
    </resultMap>  

    <!-- query all Users -->  
    <select id="selectAllUsers" resultMap="UserResult">  
        select * from user   
    </select>  

    <!-- query user by id -->  
    <select id="selectUserById" parameterClass="int" resultMap="UserResult">  
        select ID,LOGIN_NAME,PASS_WORD,QX,MEMO from user where ID=#id#   
    </select>  

    <!-- query user by user -->  
    <select id="selectUserByUser2" parameterClass="map" resultMap="UserResult">  
        select ID,LOGIN_NAME,PASS_WORD,QX,MEMO 
        from user 
        <dynamic prepend="where">
        <isNotEmpty prepend="and" property="name">
        LOGIN_NAME=#name#
        </isNotEmpty>
        <isNotEmpty prepend="and" property="password">
        PASS_WORD=#password#
        </isNotEmpty>
        </dynamic>
    </select>  


    <select id="selectUserByUser" parameterClass="user" resultMap="UserResult">  
        select ID,LOGIN_NAME,PASS_WORD,QX,MEMO 
        from user 
        <dynamic prepend="where">
        <isNotEmpty prepend="and" property="name">
        LOGIN_NAME=#name#
        </isNotEmpty>
        <isNotEmpty prepend="and" property="password">
        PASS_WORD=#password#
        </isNotEmpty>
        </dynamic>
    </select>  

    <select id="selectUsersByName" parameterClass="String" resultMap="UserResult">  
        select ID,LOGIN_NAME,PASS_WORD,QX,MEMO 
        from user 
         <dynamic prepend="where">
        <isNotEmpty prepend="and" property="value">
        sname like '%$value$%'
        </isNotEmpty>
        </dynamic>
    </select>  

    <!--     
    <insert id="addUser" parameterClass="User">  
        insert into user(LOGIN_NAME,PASS_WORD,QX,MEMO ) 
        values(#name#,#birth#,#score#)   
        <selectKey keyProperty="id" resultClass="int">
             select last_insert_id()
        </selectKey>
    </insert> 
     <!-- 注意这里的keyProperty="id" 中的id就是User中的id属性，resultClass就是查询的的返回值 -->
    -->  

    <update id="updateUser" parameterClass="User">  
        update user set LOGIN_NAME=#name#,PASS_WORD=#password#,QX=#qx#,memo=#memo# where  ID=#id#   
    </update>  

    <delete id="deleteUser" parameterClass="int">  
        delete from user where ID=#id#   
    </delete>  

</sqlMap>

【补充：】动态sql：

一般来说，拼接动态sql是在查询时，指定多个查询条件的情况下用的，所以用到parameterClass= (map或具体类)，

但对于传递过来的参数就一个时，若如下代码就会出错：

<select id="selectUserById" parameterClass="int"  resultMap="UserResult">
      select sid,sname,smajor,sbirth,score from users 
                <dynamic prepend="where">
    <isNotEmpty prepend="and" property="id">
sid=#id#
    </isNotEmpty>
</dynamic>
</select>

会报错误如下：There is no READABLE property named 'id' in class 'java.lang.Integer'

因为你无缘故用了一个莫名其妙的property="id",id对ibatis来说不认识。

这时的解决办法有两种，一个是这里的property="id" 中的id用value来代替，所以下面的sid=#value#，这个value是ibatis内部指定个变量；另一个方法是直接把property="id"删除，不用property这个属性了。

五、ibatis主配置文件编写【主配置文件只剩下sqlMap了，事务和数据源都交给spring进行配置和管理】

本例为sql-map-config.xml:(位置：)

<?xml version="1.0" encoding="UTF-8" ?>  
<!DOCTYPE sqlMapConfig         
    PUBLIC "-//ibatis.apache.org//DTD SQL Map Config 2.0//EN"         
    "<a href="http://ibatis.apache.org/dtd/sql-map-config-2.dtd">http://ibatis.apache.org/dtd/sql-map-config-2.dtd</a>">  
<sqlMapConfig>  
     <sqlMap resource="com/leadtone/ibatis/sqlmap/User.xml"/>  
     
     <!-- 
     <sqlMap resource="com/leadtone/ibatis/sqlmap/User1.xml"/>  
     <sqlMap resource="com/leadtone/ibatis/sqlmap/User2.xml"/>  
     
     <sqlMap resource="com/leadtone/ibatis/sqlmap/Usern.xml"/> 
      -->
</sqlMapConfig>

六、dao接口和接口实现

1）、本例为UserDao：

package com.leadtone.ibatis.dao;

import java.util.List;
import com.leadtone.ibatis.domain.User;

public interface IUserDao {
public List<User> queryAllUsers();
public User queryUserById(int id);
public User queryUserByUser(User user);
public List<User> queryUserByName(String name);

public void addUser(User user);
public void addUserBySequence(User user);

public void updateUser(User user);

public void deleteUser(int id);
}

2）、实现类UserDaoImpl：

package com.leadtone.ibatis.dao.ibatis;

import java.util.List;
import org.springframework.orm.ibatis.support.SqlMapClientDaoSupport;
import com.leadtone.ibatis.dao.IUserDao;
import com.leadtone.ibatis.domain.User;

public class UserDaoImpl extends SqlMapClientDaoSupport implements IUserDao {

//注意这里的SqlMapClient接口的声明和下面的static静态代码都不需要了，



                // 因为这里继承了spring提供的ibatis模板template类SqlMapClientDaoSupport，不是用原生的SqlMapClient



                 //private static SqlMapClient sqlMapClient=null;
/*
static{
Reader reader=null;
try {
reader=Resources.getResourceAsReader("com/leadtone/ibatis/sqlmap/SqlMapConfig.xml");
sqlMapClient=SqlMapClientBuilder.buildSqlMapClient(reader);

reader.close();
} catch (IOException e) {
e.printStackTrace();
}

}
*/
public void addUser(User user) {
getSqlMapClientTemplate().insert("addUser", user);
}

public User queryUserByUser(User user) {
System.out.println("---UserDaoImpl---");
return (User) this.getSqlMapClientTemplate().queryForObject("selectUserByUser", user);

}
/*
* 这里主要演示一个模拟用户登录系统验证的操作，主要用了queryUserByUser(User user)方法
*/
}

3）、在spring配置文件中配置这个bean

<!--sqlMapClient  -->
<bean id="sqlMapClient"  class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">
<property name="configLocation" value="sqlmap/sql-map-config.xml"/>
<property name="dataSource" ref="dataSource" />
</bean>

<!-- validate loginUser -->
<!-- dao -->
<bean id="userDao" class="com.leadtone.ibatis.dao.ibatis.UserDaoImpl">
      <property name="sqlMapClient" ref="<span style="color: #000000;">sqlMapClient </span>"></property>
</bean>

七、service接口和接口实现

1）IUserLoginService接口

package com.leadtone.ibatis.service;

import com.leadtone.ibatis.domain.User;

public interface IUserLoginService {
public boolean isLoginUser(User user);
}

2）UserLoginSerivceImpl实现类

package com.leadtone.ibatis.service.impl;

import com.leadtone.ibatis.dao.IUserDao;
import com.leadtone.ibatis.domain.User;
import com.leadtone.ibatis.service.IUserLoginService;

public class UserLoginServiceImpl implements IUserLoginService {

private IUserDao userDao;

public IUserDao getUserDao() {
return userDao;
}

public void setUserDao(IUserDao userDao) {
this.userDao = userDao;
}
public boolean isLoginUser(User user) {
return null!=userDao.queryUserByUser(user)?true:false;
}

}

3）在spring中注册这个bean

<!-- service -->
<bean id="userLoginService" class="com.leadtone.ibatis.service.impl.UserLoginServiceImpl">
        <property name="userDao" ref="userDao"></property>
</bean>

八、struts action实现及struts-config.xml配置(牵扯到struts和spring的整合)

1）action：

package com.leadtone.web.struts.action;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;

import com.leadtone.ibatis.domain.User;
import com.leadtone.ibatis.service.IUserLoginService;
import com.leadtone.web.struts.form.LoginForm;

public class LoginAction extends Action {

private IUserLoginService userLoginService;

public IUserLoginService getUserLoginService() {
return userLoginService;
}

public void setUserLoginService(IUserLoginService userLoginService) {
this.userLoginService = userLoginService;
}

public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
LoginForm loginForm = (LoginForm) form;
String name=loginForm.getUsername();
String password=loginForm.getPassword();

User user=new User();
user.setName(name);
user.setPassword(password);
boolean isLogin=false;
isLogin = userLoginService.isLoginUser(user);
System.out.println(isLogin);
if(isLogin){
request.setAttribute("username", name);
return mapping.findForward("success");
}
else
return mapping.findForward("failure");
}
}

2）actionForm:

public class LoginForm extends ActionForm {

private String username;
private String password;
private String grade;

public ActionErrors validate(ActionMapping mapping,
HttpServletRequest request) {
return null;
}

public void reset(ActionMapping mapping, HttpServletRequest request) {
}

public String getPassword() {
return password;
}

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

public String getGrade() {
return grade;
}
public void setGrade(String grade) {
this.grade = grade;
}

public String getUsername() {
return username;
}

public void setUsername(String username) {
this.username = username;
}
}

3）xml：

<struts-config>
  <data-sources />
  <form-beans >
    <form-bean name="loginForm" type="com.leadtone.web.struts.form.LoginForm" />

  </form-beans>

  <global-exceptions />
  <global-forwards />
  <action-mappings >
    <action
      attribute="loginForm"
      input="/login.jsp"
      name="loginForm"
      path="/login"
      scope="request"
      type="org.springframework.web.struts.DelegatingActionProxy">

      <forward name="failure" path="/failure.jsp" />
      <forward name="success" path="/succ.jsp" />
    </action>


  </action-mappings>

  <controller processorClass="org.springframework.web.struts.DelegatingRequestProcessor"></controller>

  <message-resources parameter="com.leadtone.web.struts.ApplicationResources" />

  <plug-in className="org.springframework.web.struts.ContextLoaderPlugIn">
    <set-property property="contextConfigLocation" value="classpath:applicationContext.xml" />
  </plug-in>
</struts-config>

4）页面：

<body >
<center>
<html:form action="${Pagecontext.request.contextPath}/login" method="post">
<table border="1px" cellspacing="1px" cellpadding="1px" >
<tr>
<td>username : </td>
<td><html:text property="username"/></td>
<td><html:errors property="username"/></td>
</tr>
<tr>
<td>password : </td>
<td><html:password property="password"/></td>
<td><html:errors property="password"/></td>
</tr>
<tr>
<td>grade:  </td>
<td> <html:select property="grade">
<html:option value="guest">guest</html:option>
<html:option value="admin">admin</html:option>
</html:select>
</td>
<td><html:errors property="grade"/></td>
</tr>
<tr >
<td colspan="3" valign="middle" align="center"><html:submit/> <html:cancel/></td>

</tr>
</table>
</html:form>
</center>
</body>

succ.jsp

 <body>
   welcome ${username}, <br>
   login successfully!
 </body>



falure.jsp 

  <body>
      sorry,login error<a href="login.jsp">relogin</a>
  </body>

5)web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.5" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee   http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
  <servlet>
    <servlet-name>action</servlet-name>
    <servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
    <init-param>
      <param-name>config</param-name>
      <param-value>/WEB-INF/struts-config.xml</param-value>
    </init-param>    
    <init-param>
      <param-name>debug</param-name>
      <param-value>3</param-value>
    </init-param>
    <init-param>
      <param-name>detail</param-name>
      <param-value>3</param-value>
    </init-param>
    <load-on-startup>0</load-on-startup>
  </servlet>

  <servlet-mapping>
    <servlet-name>action</servlet-name>
    <url-pattern>*.do</url-pattern>
  </servlet-mapping>
  <welcome-file-list>
    <welcome-file>login.jsp</welcome-file>
  </welcome-file-list>
</web-app>

九、spring配置文件的内容【牵扯到ibatis和struts的整合】

<!-- action -->
<bean name="/login" class="com.leadtone.web.struts.action.LoginAction" abstract="false"
lazy-init="default" autowire="default" dependency-check="default">
<property name="userLoginService" ref="userLoginService"></property>
</bean>

十、测试

这里的测试包括单元测试。例如对dao层、service层、action层编写完成后都要进行junit4单元测试（Jmock或easyMock等）测试，这里就不添加了。

spring的配置文件中对事物拦截器的配置，也是必须的，这里没有配置
