1.整合spring与hibernate，spring的ioc与hibernate均运用注解，hibernate操作数据库用hibernateTemplate,加上了声明式事务管理。
2.
hibernate需要的包：
spring需要的相关包:
连接 oracle 所需包：
3.新建Java项目，创建lib文件夹，将以上jar包复制在里面，并且右键jar包，add to build path,将其加入构建路径。
4.加入model层，包括Student和Teacher
package com.model;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.SequenceGenerator;
@Entity
public class Student {
private int id;
private String name;
private int age;
@SequenceGenerator(name="sequenceGenerator",sequenceName="student_sequence",allocationSize=1)
@GeneratedValue(strategy=GenerationType.SEQUENCE, generator="sequenceGenerator")
@Id
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
}
package com.model;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.SequenceGenerator;
@Entity
public class Teacher {
private int id;
private String name;
private int wage;
@SequenceGenerator(name="sequenceGenerator",sequenceName="teacher_sequence",allocationSize=1)
@GeneratedValue(strategy=GenerationType.SEQUENCE, generator="sequenceGenerator")
@Id
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getWage() {
return wage;
}
public void setWage(int wage) {
this.wage = wage;
}
}
5.加入dao层，包括StudentDao和TeacherDao
package com.dao;
import java.util.List;
import com.model.Student;
public interface StudentDao {
public void save(Student s);
public List<Student> queryByName(String name);
}
package com.dao;
import java.util.List;
import com.model.Teacher;
public interface TeacherDao {
public void save(Teacher t);
public List<Teacher> queryByName(String name);
}
6.加入DaoImpl层，包括StudentDaoImpl和TeacherDaoImpl
package com.dao.impl;
import java.util.List;
import javax.annotation.Resource;
import org.springframework.orm.hibernate3.HibernateTemplate;
import org.springframework.stereotype.Component;
import com.dao.StudentDao;
import com.model.Student;
@Component
public class StudentDaoImpl implements StudentDao {
private HibernateTemplate hibernateTemplate;
public HibernateTemplate getHibernateTemplate() {
return hibernateTemplate;
}
@Resource
public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {
this.hibernateTemplate = hibernateTemplate;
}
public void save(Student s) {
hibernateTemplate.save(s);
}
public List<Student> queryByName(String name){
String sql = "from Student s where s.name=?";
List<Student> list = hibernateTemplate.find(sql,name);
return list;
}
}
package com.dao.impl;
import java.util.List;
import javax.annotation.Resource;
import org.springframework.orm.hibernate3.HibernateTemplate;
import org.springframework.stereotype.Component;
import com.dao.TeacherDao;
import com.model.Teacher;
@Component
public class TeacherDaoImpl implements TeacherDao{
private HibernateTemplate hibernateTemplate;
public HibernateTemplate getHibernateTemplate() {
return hibernateTemplate;
}
@Resource
public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {
this.hibernateTemplate = hibernateTemplate;
}
public void save(Teacher t){
hibernateTemplate.save(t);
}
@SuppressWarnings("unchecked")
public List<Teacher> queryByName(String name){
String sql = "from Teacher t where t.name=?";
List<Teacher> list = hibernateTemplate.find(sql,name);
return list;
}
}7.加入service层，包括ST_Service
package com.service;
import javax.annotation.Resource;
import org.springframework.stereotype.Component;
import com.dao.StudentDao;
import com.dao.TeacherDao;
import com.model.Student;
import com.model.Teacher;
@Component("sT_Service")
public class ST_Service {
private StudentDao studentDao;
private TeacherDao teacherDao;
public StudentDao getStudentDao() {
return studentDao;
}
@Resource(name="studentDaoImpl")
public void setStudentDao(StudentDao studentDao) {
this.studentDao = studentDao;
}
public TeacherDao getTeacherDao() {
return teacherDao;
}
@Resource(name="teacherDaoImpl")
public void setTeacherDao(TeacherDao teacherDao) {
this.teacherDao = teacherDao;
}
public void addStudentAndTeacher(Student s,Teacher t){
studentDao.save(s);
teacherDao.save(t);
}
}
8.在src目录下加入bean.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" xmlns:context="http://www.springframework.org/schema/context" 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/context http://www.springframework.org/schema/context/spring-context-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">
<context:annotation-config />
<context:component-scan base-package="com.dao.impl,com.service" />
<bean id="myDataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">

<property name="url" value="jdbc:oracle:thin:@127.0.0.1:1521:orcl"/>
<property name="username" value="cat"/>
<property name="password" value="cat"/>
</bean>
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="dataSource" ref="myDataSource" />
<property name="packagesToScan">
<list>
<value>com.model</value>
</list>
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.OracleDialect</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.format_sql">true</prop>
<prop key="hibernate.hbm2ddl.auto">update</prop>
<prop key="hibernate.max_fetch_depth">1</prop>
<prop key="hibernate.use_sql_comments">true</prop>
</props>
</property>
</bean>
<bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"/>
</bean>
<tx:advice id="txAdvice" transaction-manager="txManager">
<tx:attributes>
<tx:method name="get*" read-only="true"/>
<tx:method name="*"/>
</tx:attributes>
</tx:advice>
<aop:config>
<aop:pointcut id="serviceOperation" expression="execution(public * com.service.*.*(..))"/>
<aop:advisor advice-ref="txAdvice" pointcut-ref="serviceOperation"/>
</aop:config>
<bean id="hibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>
</beans>9.加入测试类 Test
package com.test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.model.Student;
import com.model.Teacher;
import com.service.ST_Service;
public class Test {
public static void main(String[] args) {
Student s = new Student();
s.setName("tom");
s.setAge(11);
Teacher t = new Teacher();
t.setName("lily");
t.setWage(3000000);
ApplicationContext context = new ClassPathXmlApplicationContext("beans.xml");
ST_Service ss = (ST_Service)context.getBean("sT_Service");
ss.addStudentAndTeacher(s, t);
}
}
