ibatis+spring整合简单完整例子

Spring和Ibatis框架整合的思路与spring和hibernate框架的整合思路基本一致。 
步骤一：新建立一个项目。 
步骤二：为该项目添加spring的应用环境。 
步骤三：导入Ibatis的必须JAR包以及数据库JAR包。 
步骤四：新建实体Bean。如下： 
package cn.test.entity; 
import java.io.Serializable; 
/** 
* @author Administrator 
* 
*学生实体Bean 
* 
*/ 
public class Student implements Serializable { 
/** 
* 
*/ 
private static final long serialVersionUID = 1L; 
private Integer id; 

private String studentname; 

private Integer studentage; 

private String studentaddress; 
public Integer getId() { 
return id; 
} 
public void setId(Integer id) { 
this.id = id; 
} 
public String getStudentname() { 
return studentname; 
} 
public void setStudentname(String studentname) { 
this.studentname = studentname; 
} 
public Integer getStudentage() { 
return studentage; 
} 
public void setStudentage(Integer studentage) { 
this.studentage = studentage; 
} 
public String getStudentaddress() { 
return studentaddress; 
} 
public void setStudentaddress(String studentaddress) { 
this.studentaddress = studentaddress; 
} 
} 
步骤五：新建相应的Bean的配置文件。如下：Student.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> 
<!– 查询操作 –> 
<select id=”getAllStudent” resultClass=”cn.test.entity.Student”> 
select * from student where 1=1 
</select> 
<!– 通过编号获取信息 –> 
<select id=”getStudentById” resultClass=”cn.test.entity.Student” parameterClass=”Integer”> 
select * from student where id=#ids# 
</select> 
</sqlMap> 
步骤六：新建Ibatis的应用配置文件。sql-map-config.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> 
<!– 通知spring到哪里去寻找配置文件 –> 
<sqlMap resource=”cn/test/configfile/Student.xml”/> 
</sqlMapConfig> 
步骤七：修改spring的applicationContext.xml文件。添加如下代码： 
<!– 配置数据源 –> 
<bean id=”dataSource”> 
<property name=”driverClassName”> 
<value>com.mysql.jdbc.Driver</value> 
</property> 
<property name=”url”> 
<value>jdbc:mysql://localhost:3306/test</value> 
</property> 
<property name=”username”> 
<value>root</value> 
</property> 
<property name=”password”> 
<value>root</value> 
</property> 
</bean> 
<!– spring的ibatis 配制 –> 
<bean id=”sqlMapClient”> 
<property name=”dataSource”> 
<ref bean=”dataSource”/> 
</property> 
<property name=”configLocation”> 
<value>cn/test/configfile/sql-map-config.xml</value> 
</property> 
</bean> 
<!– 配置模板 –> 
<bean id=”sqlMapClientTemplate”> 
<property name=”sqlMapClient”> 
<ref bean=”sqlMapClient”/> 
</property> 
</bean> 
步骤八：书写数据持久层次以及业务层代码。数据持久层代码如下： 
public class StudentDAOImple implements IStudentDAO{ 
private SqlMapClientTemplate sqlMapClientTemplate; 
public void setSqlMapClientTemplate(SqlMapClientTemplate sqlMapClientTemplate) { 
this.sqlMapClientTemplate = sqlMapClientTemplate; 
} 
public List<Student> getAllStudent() { 

List<Student> list = sqlMapClientTemplate.queryForList(“getAllStudent”); 

return list; 

} 

} 
以及修改修改spring的applicationContext.xml文件 
<!– DAO –> 
<bean id=”studentDAO”> 
<property name=”sqlMapClientTemplate”> 
<ref bean=”sqlMapClientTemplate”/> 
</property> 
</bean> 
步骤九：建立测试类以及测试方法。 
public class Test { 
/** 
* @param args 
*/ 
public static void main(String[] args) { 

ApplicationContext factory = new ClassPathXmlApplicationContext(“applicationContext.xml”); 

IStudentDAO dao = (IStudentDAO) factory.getBean(“studentDAO”); 
List<Student> list = dao.getAllStudent(); 

for (int i = 0; i < list.size(); i++) { 

Student stu = list.get(i); 

System.out.println(stu.getId()+”:”+stu.getStudentname()+”:”+stu.getStudentage()+”:”+stu.getStudentaddress());

} 
} 
}
