      最近一直在看spring和ibatis的东西，由于目前SSH的流行，大多讲Spring和Hibernate的整合开发，作者一直对Hibernate不是很感冒，也许是因为日常开发程序对性能要求比较高，和Hibernate比较起来Ibatis更合适。虽然网络上有很多讲Spring和Ibatis整合的文章，但查看了许多，发现能顺利开发下去的文章太少，于是我就为大家准备了这篇Spring+Ibatis的入门级整合文章。

环境介绍

      先来介绍一下本入门级整合文章所用到的环境：Spring2.5.5、Ibatis2.3.0、JDK1.6、Oracle数据库，如果没有用过Oracle的读者读到这里请不要慌张，因为本实例还会讲解Mysql和SqlServer的。

程序介绍

      实例中要求完成Spring与Ibatis的整合，并往数据库的UserInfo表中插入用户信息。

开发部分

好了，下面我们开始边开发边讲解吧，Let's go！

1、首先我们一起先来看看本实例的整个目录结构

从图中，我们可以看出，这个spring_ibatis工程下有2个代码包：study.spring.dao、study.spring.manager

                                                                       2个文件夹：properties、sqlmap

                                                                除jdk外的jar包：ibatis下的jar包：ibatis-2.3.0.677.jar

                                                                                       oracle下的jar包：classes12.jar

                                                                                       spring下的jar包：spring.jar、commons-logging.jar、log4j.jar

其中：properties文件夹下放置这spring的配置文件applicationContext.xml和Ibatis的配置文件SqlMapConfig.xml

         sqlmap文件夹下放置的是Ibatis的SqlMap配置文件（最终转化成可执行的SQL语句）

         包study.spring.dao下有3个java文件：

                                                               1）UserInfo：用户类

                                                               2）UserDao：数据库操作接口

                                                               3）User4OracleImpl：数据库操作实现类，继承与UserDao接口

        包study.spring.manager下有2个java文件：

                                                               1）UserManager：数据库操作管理类

                                                               2）Client：测试主类

2、在数据库中新建一张UserInfo表

CREATE TABLE userinfo
(
   userid     varchar2 (10),  --用户ID
   username   varchar2 (20),  --用户名
   password   varchar2 (16),  --密码
   age        int             --年龄
);

 

3、在study.spring.dao下建立一个与数据库Userinfo表对应的Java类

package study.spring.dao;
public class UserInfo {

    private String userid;

    private String username;

    private String password;

    private int age;
    public int getAge() {
        return age;
    }
    public void setAge(int age) {
        this.age = age;
    }
    public String getPassword() {
        return password;
    }
    public void setPassword(String password) {
        this.password = password;
    }
    public String getUserid() {
        return userid;
    }
    public void setUserid(String userid) {
        this.userid = userid;
    }
    public String getUsername() {
        return username;
    }
    public void setUsername(String username) {
        this.username = username;
    }
}

 

4、配置Ibatis的数据库连接信息

在properties下的SqlMapClient.xml中添加如下语句

<?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>
    <!-- MySQL 连接的配置信息-->
    <!--
        <transactionManager type="JDBC" commitRequired="false">
        <dataSource type="SIMPLE">
        <property name="JDBC.Driver" value="com.mysql.jdbc.Driver"/>
        <property name="JDBC.ConnectionURL" value="jdbc:mysql://localhost:3306/test"/>
        <property name="JDBC.Username" value="root"/>
        <property name="JDBC.Password" value="root"/>
        </dataSource>
        </transactionManager>
    -->
    <!-- Oracle 连接的配置信息 -->
        <transactionManager type="JDBC">
        <dataSource type="SIMPLE">
        <property name="JDBC.Driver" value="oracle.jdbc.driver.OracleDriver"/>
        <property name="JDBC.ConnectionURL" value="jdbc:oracle:thin:@10.60.108.11:1550:cdbeff"/>
        <property name="JDBC.Username" value="cdbeff"/>
        <property name="JDBC.Password" value="password"/>
        <property name="Pool.MaximumActiveConnections" value="10"/>
        <property name="Pool.MaximumIdleConnections" value="5"/>
        <property name="Pool.MaximumCheckoutTime" value="120000"/>
        <property name="Pool.TimeToWait" value="500"/>
        <property name="Pool.PingQuery" value="select 1 from dual"/>
        <property name="Pool.PingEnabled" value="false"/>
        <property name="Pool.PingConnectionsOlderThan" value="1"/>
        <property name="Pool.PingConnectionsNotUsedFor" value="1"/>
        </dataSource>
        </transactionManager>
    <!-- SQL Server 连接的配置信息
    <transactionManager type="JDBC" commitRequired="false">
        <dataSource type="SIMPLE">
            <property name="JDBC.Driver"
                value="com.microsoft.jdbc.sqlserver.SQLServerDriver" />
            <property name="JDBC.ConnectionURL"
                value="jdbc:microsoft:sqlserver://localhost:1433;databaseName=pubs;SelectMethod=Cursor" />
            <property name="JDBC.Username" value="sa" />
            <property name="JDBC.Password" value="" />
        </dataSource>
    </transactionManager>
     -->
    <!-- SqlMap的配置文件 -->
    <sqlMap resource="sqlmap/SqlMap_UserInfo.xml" />
</sqlMapConfig>

 

5、整合spring和ibatis

在properties的applicationContext.xml中添加如下语句

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xmlns:aop="http://www.springframework.org/schema/aop"
        xmlns:tx="http://www.springframework.org/schema/tx"
        xsi:schemaLocation="
            http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
            http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd
            http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd">

        <!-- 整合ibatis -->
        <bean id="SqlMapClientFactoryBean" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">
            <property name="configLocations">
                <value>properties/SqlMapConfig.xml</value>
            </property>
        </bean>
        <bean id="userInfo" class="study.spring.dao.UserInfo">
            <property name="userid" value="51048"></property>
            <property name="username" value="zhanhj"></property>
            <property name="password" value="dcfszhj09"></property>
            <property name="age" value="24"></property>
        </bean>
        <bean id="userDao4OracleImpl" class="study.spring.dao.User4OracleImpl">
            <!-- sqlMapClient虽不是类userDao4OracleImpl的属性，但此处sqlMapClient必须要配置 -->
            <property name="sqlMapClient" ref="SqlMapClientFactoryBean"></property>
        </bean>
        <bean id="userManager" class="study.spring.manager.UserManager">
            <property name="userDao" ref="userDao4OracleImpl"></property>
        </bean>
</beans>

 

在此文件中，其中整合ibatis的为如下语句，其余的配置信息为本程序的其他实现类的bean

<!-- 整合ibatis -->
<bean id="SqlMapClientFactoryBean" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">
<property name="configLocations">
<value>properties/SqlMapConfig.xml</value>
</property>
</bean>

 

6、UserDao的实现

package study.spring.dao;
import com.ibatis.sqlmap.client.SqlMapClient;
public interface UserDao {

    public void save(SqlMapClient client, UserInfo user);
    public void delete(SqlMapClient client, UserInfo user);
}

 

7、User4OracleImpl的实现

package study.spring.dao;
import java.sql.SQLException;
import org.springframework.orm.ibatis.support.SqlMapClientDaoSupport;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import com.ibatis.sqlmap.client.SqlMapClient;
public class User4OracleImpl extends SqlMapClientDaoSupport implements UserDao {
    private Log log = LogFactory.getLog(User4OracleImpl.class);
    // 删除用户信息
    public void delete(SqlMapClient client, UserInfo user) {
        try {
            client.delete(user.getUserid());
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }
    // 保存用户信息
    public void save(SqlMapClient client, UserInfo user) {
        try {
            client.startTransaction();
            client.insert("insertUserInfo", user);
            log.info(user.getUserid() + "的信息插入成功!");
            client.commitTransaction();
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }
}

 

8、UserManager的实现

package study.spring.manager;
import com.ibatis.sqlmap.client.SqlMapClient;
import study.spring.dao.UserDao;
import study.spring.dao.UserInfo;
public class UserManager {
    public UserDao userDao;
    public void setUserDao(UserDao userDao) {
        this.userDao = userDao;
    }
    public void save(SqlMapClient client, UserInfo user) {
        userDao.save(client, user);
    }
    public void delete(SqlMapClient client, UserInfo user) {
        userDao.delete(client, user);
    }
}

 

9、SqlMap的配置文件信息

<?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>
  <typeAlias alias="Userinfo" type="study.spring.dao.UserInfo"/>
  <resultMap id="queryResult" class="Userinfo">
    <result property="userid" column="userid"/>
    <result property="username" column="username"/>
    <result property="password" column="password"/>
    <result property="age" column="age"/>
  </resultMap>
  <select id="selectAllusers" resultMap="queryResult">
    select * from userinfo
  </select>

  <!-- Insert example, using the Userinfo parameter class -->
  <insert id="insertUserInfo" parameterClass="Userinfo">
    insert into userinfo (
      userid,
      username,
      password,
      age)
    values (
      #userid#, #username#, #password#, #age#
    )
  </insert>
  <!-- Delete example, using an String as the parameter class -->
  <delete id="deleteUserById" parameterClass="java.lang.String">
    delete from userinfo where userid = #userid#
  </delete>

</sqlMap>

 

10、Client测试主类的实现

package study.spring.manager;
import org.springframework.beans.factory.BeanFactory;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.ibatis.sqlmap.client.SqlMapClient;
import study.spring.dao.UserInfo;
import junit.framework.TestCase;
public class Client extends TestCase{

    public static void main(String[] args) {
        BeanFactory factory = new ClassPathXmlApplicationContext("properties/applicationContext.xml");
        UserManager userManager = (UserManager) factory.getBean("userManager");
        UserInfo user = (UserInfo)factory.getBean("userInfo");
        SqlMapClient client = (SqlMapClient)factory.getBean("SqlMapClientFactoryBean");
        userManager.save(client,user);

    }
}

 

11、测试结果

2010-11-22 20:05:47,187 INFO [org.springframework.context.support.ClassPathXmlApplicationContext] - Refreshing org.springframework.context.support.ClassPathXmlApplicationContext@197d257: display name [org.springframework.context.support.ClassPathXmlApplicationContext@197d257]; startup date [Mon Nov 22 20:05:47 CST 2010]; root of context hierarchy

到这里，需要讲解的内容就结束了，下面我们一起来总结一下：

      1、spring整合ibatis：在applicationContext.xml中将ibatis的sqlMapClient注入（参考第5点）

      2、ibatis配置数据库连接信息（包括Oracle、MySql、Sql Server，参考第4点）

其他的各位一一理解吧，今天先到这里，再见！
