Spring与iBATIS整合及Struts1文件的上传与下载1

案例是关于联系人信息列表展示,使用spring+struts+ibatis实现,附件有整个工程文件

 

1.联系人表的创建，使用的是MySQL

CREATE TABLE `contact` (
  `id` int(11) NOT NULL auto_increment,
  `firstName` varchar(20) default NULL,
  `lastName` varchar(20) default NULL,
  `email` varchar(20) default NULL,
  `imgPath` varchar(200) default 'None',
  `imgFileName` varchar(200) default 'None',
  PRIMARY KEY  (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=35 DEFAULT CHARSET=gbk;

 

 

2.联系人的表的映射

<?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="Contact">
    <!--- Showing data by ID -->
    <typeAlias alias="contact" type="cn.com.servyou.ibatis_learn.entity.Contact"/>
    <typeAlias alias="address" type="cn.com.servyou.ibatis_learn.entity.Address"/>
 
    <!-- Contact映射 -->
    <resultMap id="get_user_result" class="contact">   
        <result property="id" column="id"/>    
        <result property="firstName" column="firstName"/>   
        <result property="lastName" column="lastName"/>   
        <result property="email" column="email"/>
        <result property="imgPath" column="imgPath"/>
        <result property="imgFileName" column="imgFileName"/>
        <result property="addresses" column="id" select="Contact.getAddressesByContactId"/>
    </resultMap>      
   
    <!-- Address映射 -->
    <!-- 
    <resultMap id="get_address_result" class="address">
        <result property="id" column="id"/>
        <result property="addressName" column="addressName"/>
        <result property="zipCode" column="zipCode"/>
        <result property="contactId" column="contact_id"/>
    </resultMap>
    -->   
     
         
    <select id="getContactByLastName" resultClass="contact" resultMap="get_user_result" parameterClass="java.lang.String">         
        select * from contact    
        where lastName = #lastName#
    </select>  
   
    <select id="getAllContact" resultClass="contact" resultMap="get_user_result">         
        select * from contact    
    </select>  
      
     <select id="getAddressesByContactId" resultClass="address"  parameterClass="int" >
        select * from address
        where contact_id = #contact_id# 
    </select>  
        
       
    <insert id="insert" parameterClass="cn.com.servyou.ibatis_learn.entity.Contact">          
        insert into  contact  
                       (firstName,lastName,email,imgPath,imgFileName)          
        values
                    (#firstName#, #lastName#, #email#,#imgPath#,#imgFileName#)          
    </insert>    
   
    <delete id="delete" parameterClass="cn.com.servyou.ibatis_learn.entity.Contact">
        delete from contact
        where lastName = #lastName#
    </delete>  
   
    <delete id="deleteContactByLastName" parameterClass="java.lang.String">
        delete from contact         
        where lastName = #value#
    </delete>  
       
    <update id="update" parameterClass="java.lang.Integer">
            update  contact  
                    set email = '[e-mail]'
            where id = #id#  
    </update>
     
    <update id="updateByLastName" parameterClass="contact">
        update contact
                set email = #email#
            where lastName = #lastName#
    </update>
</sqlMap>   

 

 

 

3.关于联系人的Dao,与Service的实现类的代码就省略了，下面只是给出接口的定义

IContactDao:

 

public interface IContactDao  {
    public List<Contact> findAll() throws DAOException;
   
    public Contact findByLastName(String lastName) throws DAOException;
   
    public void insert(Contact contact) throws DAOException;
   
    public void delete(Contact contact) throws DAOException;
   
    public void deleteByLastName(String lastName) throws DAOException;
     
    public void updateById(Integer id) throws DAOException;
   
    public void updateByLastName(Contact contact) throws DAOException;
   
}

 

 

 

IContactService:

 

public interface IContactService {
    public List<Contact> getAll() throws ServiceException;

    public void addContact(Contact contact) throws ServiceException;

    public void deleteContact(Contact contact) throws ServiceException;
   
    public void deleteContactByLastName(String lastName) throws ServiceException;

    public void updateContactById(Integer id) throws ServiceException;

    public void updateContactByLastName(Contact contact)
            throws ServiceException;

    public Contact findContactByLastName(String lastName)
            throws ServiceException;
}
