아래 실습에서 사용되는 XML파일들은 모두 src/main/resources 아래에 만들었음.
이전 스프링, 하이버네이트 예제와 크게 다른 점은
- 자바파일에 Annotation을 이용하여 작성(Entity Class인 MyEmp.java 파일이 많이 바뀜)
- XML파일(myemp.hmb.xml,myemp.xml 파일 삭제됨)
- Hibernate xml 파일의 sessionFactory 클래스 파일이 AnnotationSessionFactoryBean으로 바뀜
- Beanlocations.xml에 context:component-scan 패키지 경로 추가
1. 이클립스에서 하이버네이트 유틸리티 프로젝트 나 간단히 스프링프로젝트 하나 만들자.
프로젝트 전체 모양은 아래와 같다.
2. pom.xml은 다음과 같다.

3. onj.edu.hibernate.model 클래스
[MyEmp.java]
package onj.edu.hibernate.model;
import java.io.Serializable;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;
//myemp 테이블의 도메인 클래스
@Entity
@Table(name="myemp")
public class MyEmp implementsSerializable{
@Column(name="empno", unique=true, nullable=false)
private Integer empno;
private String ename;
public Integer getEmpno() {
return empno;
}
public void setEmpno(Integer empno) {
this.empno = empno;
}
public StringgetEname() {
return ename;
}
public void setEname(String ename) {
this.ename = ename;
}
}
4. 다은은 BusinessObject 클래스를 만들자
[MyEmpBo.java]
package onj.edu.hibernate.bo;
import onj.edu.hibernate.model.MyEmp;
public interface MyEmpBo {
// empno를 key로 데이터 selcet
public MyEmpgetMyEmp(int empno);
// insert
public void setMyEmp(MyEmp myEmp);
// update
public void updateMyEmp(MyEmp myEmp);
// 이름으로 데이터 select
public MyEmpfindEmpByName(String name);
}
[MyEmpBoImpl.java]
package onj.edu.hibernate.bo;
import onj.edu.hibernate.dao.MyEmpDao;
import onj.edu.hibernate.model.MyEmp;
importorg.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
@Service("myEmpBo")
public class MyEmpBoImpl implements MyEmpBo {
@Autowired
MyEmpDao myEmpDao;
public void setMyEmpDao(MyEmpDao myEmpDao) {
this.myEmpDao = myEmpDao;
}
public MyEmpgetMyEmp(int empno) {
return myEmpDao.getMyEmp(empno);
}
public void setMyEmp(MyEmp myEmp) {
myEmpDao.setMyEmp(myEmp);
}
public void updateMyEmp(MyEmp myEmp) {
myEmpDao.updateMyEmp(myEmp);
}
public MyEmpfindEmpByName(String name) {
return myEmpDao.findEmpByName(name);
}
}
5. Data Access Object(DAO) 관련 클래스
[MyEmpDao.java]
package onj.edu.hibernate.dao;
import onj.edu.hibernate.model.MyEmp;
public interface MyEmpDao {
//empno를 key로 데이터 selcet
public MyEmp getMyEmp(int empno);
//insert
public void setMyEmp(MyEmp myEmp);
//update
public void updateMyEmp(MyEmp myEmp);
//이름으로 데이터 select
public MyEmp findEmpByName(String name);
}
[MyEmpHibernateDaoSupport.java]
package onj.edu.hibernate.util;
import org.hibernate.SessionFactory;
importorg.springframework.beans.factory.annotation.Autowired;
importorg.springframework.orm.hibernate3.support.HibernateDaoSupport;
//Annotation Mode에서 DAO클래스가 직접HibernateDaoSupport을 상속받는것은 불가능
//DAO에서 sessionFactory bean을 Autowired하는것은 불가능
public abstract class MyEmpHibernateDaoSupport extends HibernateDaoSupport
{
@Autowired
public void anyMethodName(SessionFactorysessionFactory)
{
setSessionFactory(sessionFactory);
}
}
[MyEmpDaoImpl.java]
package onj.edu.hibernate.dao;
import java.util.List;
import onj.edu.hibernate.model.MyEmp;
importonj.edu.hibernate.util.MyEmpHibernateDaoSupport;
import org.springframework.stereotype.Repository;
//Annotation Mode에서 DAO클래스가 직접HibernateDaoSupport을 상속받는것은 불가능
//DAO에서 sessionFactory bean을 Autowired하는것은 불가능
@Repository("myEmpDao")
public class MyEmpDaoImpl extendsMyEmpHibernateDaoSupport
implements MyEmpDao {
//아래에서 MyEmp.class는 Entity 클래스
public MyEmpgetMyEmp(int empno) {
return getHibernateTemplate().get(MyEmp.class, empno);
}
public void setMyEmp(MyEmp myEmp) {
getHibernateTemplate().save(myEmp);
}
public void updateMyEmp(MyEmp myEmp) {
getHibernateTemplate().update(myEmp);
}
//주의 : 아래 from절다음의 테이블명 자리에는 실제 DB테이블명이 아니라 myemp.hbm.xml 파일의 CLASS명과 속성명이 와야한다.
//대소문자 주의!! DB의 테이블명과 컬럼명이 아님.
//
public MyEmpfindEmpByName(String name) {
List list = getHibernateTemplate().find("from MyEmp where ename = ?", name);
return(MyEmp)list.get(0);
}
}
6. 다음은 하이버네이트 관계된 설정을 하자.
[hibernate.xml]
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.2.xsd">
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="dataSource">
<ref bean="dataSource"/>
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</prop>
<prop key="hibernate.show_sql">true</prop>
</props>
</property>
<!--
<propertyname="mappingResources">
<list>
<value>myemp.hbm.xml</value>
</list>
</property>
-->
<property name="annotatedClasses">
<list>
<value>onj.edu.hibernate.model.MyEmp</value>
</list>
</property>
</bean>
</beans>
7. 다음은 데이터베이스 관련 설정을 하자.
[database.properties]
jdbc.driverClassName=oracle.jdbc.driver.OracleDriver
jdbc.url=jdbc:oracle:thin:@192.168.0.7:1521:onj
jdbc.username=scott
jdbc.password=tiger
[datasource.xml]
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.2.xsd">
<bean
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location">
<value>database.properties</value>
</property>
</bean>
<bean id="dataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="${jdbc.driverClassName}" />
<property name="url" value="${jdbc.url}"/>
<property name="username" value="${jdbc.username}"/>
<property name="password" value="${jdbc.password}"/>
</bean>
</beans>
8 .지금까지 설정한 XML 파일을모으자.
[beanlocations.xml]
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.2.xsd">
<!-- DatabaseConfiguration -->
<import resource="datasource.xml"/>
<import resource="hibernate.xml"/>
<!--Auto scan the components -->
<context:component-scan base-package="onj.edu.hibernate.dao,onj.edu.hibernate.bo" />
</beans>
9. 테스트를 위한 ClientProgram
package onj.edu.hibernate.client;
import onj.edu.hibernate.bo.MyEmpBo;
import onj.edu.hibernate.model.MyEmp;
importorg.springframework.context.ApplicationContext;
importorg.springframework.context.support.ClassPathXmlApplicationContext;
public class HibernateClient
{
public static void main( String[] args )
{
ApplicationContext appContext =
newClassPathXmlApplicationContext("beanlocations.xml");
MyEmpBo myEmpBo =(MyEmpBo)appContext.getBean("myEmpBo");
//insert
MyEmp myEmp = new MyEmp();
myEmp.setEmpno(59192);
myEmp.setEname("오라클자바");
myEmpBo.setMyEmp(myEmp);
//ename으로 select
MyEmp myEmp2 =myEmpBo.findEmpByName("오라클자바");
System.out.println(myEmp2);
//empno로 select
MyEmp myEmp3 = myEmpBo.getMyEmp(59192);
System.out.println(myEmp2);
//update
myEmp3.setEname("OracleJava");
myEmpBo.updateMyEmp(myEmp3);
}
}
10. HibernateClient 를 실행
