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
[c-sharp] view plain copy 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
[java] view plain copy 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
[c-sharp] view plain copy <?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
[xhtml] view plain copy <?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
[xhtml] view plain copy <!-- 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
[java] view plain copy 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
[java] view plain copy 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
[java] view plain copy 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
[xhtml] view plain copy <?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
[java] view plain copy 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
[xhtml] view plain copy 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 2010-11-22 20:05:47,492 INFO [org.springframework.beans.factory.xml.XmlBeanDefinitionReader] - Loading XML bean definitions from class path resource [properties/applicationContext.xml] 2010-11-22 20:05:48,188 INFO [org.springframework.context.support.ClassPathXmlApplicationContext] - Bean factory for application context [org.springframework.context.support.ClassPathXmlApplicationContext@197d257]: org.springframework.beans.factory.support.DefaultListableBeanFactory@1319c 2010-11-22 20:05:48,255 INFO [org.springframework.beans.factory.support.DefaultListableBeanFactory] - Pre-instantiating singletons in org.springframework.beans.factory.support.DefaultListableBeanFactory@1319c: defining beans [SqlMapClientFactoryBean,userInfo,userDao4OracleImpl,userManager]; root of factory hierarchy 2010-11-22 20:05:51,194 INFO [study.spring.dao.User4OracleImpl] - 51048的信息插入成功!
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！
