hibernate和spring的整合

1.导入spring和hibernate必备的jar包文件

2.新建一个源文件config

3.项目分包和建类

4.hibernate.cfg.xml的总配置文件
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<!-- 配置方言 -->
<property name="dialect">org.hibernate.dialect.MySQLDialect</property>

<!-- 自动创建表 -->
<property name="hbm2ddl.auto">update</property>

<!-- 在控制台打印sql -->
<property name="show_sql">true</property>
<!-- 格式化sql -->
<property name="format_sql">true</property>
</session-factory>
</hibernate-configuration>

5.spring中的bean.xml总配置文件;

<?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:util="http://www.springframework.org/schema/util"

http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd">
<!-- 开启注解扫描 -->
<context:component-scan
base-package="com.eduask" />
<mvc:annotation-driven />
<!-- 引入外部资源 数据库配置文件-->
<context:property-placeholder location="classpath:db.properties"/>
<!-- 配置dbcp连接池 -->
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
<property name="url" value="${url}" />
<property name="username" value="${user}" />
<property name="password" value="${pwd}" />
<property name="driverClassName" value="${driver}" />
</bean>

<!-- 配置sessionfactory hibernate总的配置文件-->
<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="configLocation" value="classpath:hibernate/hibernate.cfg.xml"></property>
<!-- 设置数据源 -->
<property name="dataSource" ref="dataSource"/>
<!-- 配置扫描 com/eduask/pojo/mapper路径下的 mapper.xml文件-->
<property name="mappingLocations" value="classpath:com/eduask/pojo/mapper/*.hbm.xml"></property>
</bean>
<!-- 配置声明式事务 -->
<bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>
<!-- 启用事务注解 -->
<tx:annotation-driven transaction-manager="transactionManager"/>
<!-- hibernateTemplate-->
<bean id="hibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>
</beans>

6.StudentDao类

package com.eduask.dao;
import java.util.List;
import com.eduask.pojo.Student;
//定义一个StudentDao的接口;
public interface StudentDao {
//根据id查询;
Student getStudentById(int id) throws Exception ;
//查询所有;
List<Student> getStudents() throws Exception;
//添加;
void insertStudent(Student student) throws Exception;
//删除;
void deleteStudent(int id) throws Exception;
//修改;
void updateStudent(Student student) throws Exception;
}

7.StudentDaoImpl类;

package com.eduask.dao.impl;
import java.util.List;
import javax.annotation.Resource;
import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.springframework.stereotype.Repository;
import com.eduask.dao.StudentDao;
import com.eduask.pojo.Student;
@Repository
public class StudentDaoImpl implements StudentDao {
private Session session=null;
@Resource(name="sessionFactory")
public void setSessionFactory(SessionFactory sessionFactory){
this.session=sessionFactory.openSession();
}
public Student getStudentById(int id) throws Exception {
// TODO Auto-generated method stub
return (Student) session.get(Student.class, id);
}
public List<Student> getStudents() throws Exception {
//Student为大写;
String hql="from Student";
Query query=session.createQuery(hql);
return query.list();
}
public void insertStudent(Student student) throws Exception {
Transaction tr=session.beginTransaction();
session.save(student);
tr.commit();
session.close();
}
public void deleteStudent(int id) throws Exception {
// TODO Auto-generated method stub
Student student=getStudentById(id);
Transaction tr=session.beginTransaction();
session.delete(student);
tr.commit();
session.close();
}
public void updateStudent(Student student) throws Exception {
// TODO Auto-generated method stub
Transaction tr=session.beginTransaction();
session.update(student);
tr.commit();
session.close();
}
}

8.StudentTest类

package com.eduask.test;
import java.util.ArrayList;
import java.util.List;
import org.hibernate.Session;
import org.hibernate.Transaction;
import org.junit.Before;
import org.junit.Test;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.eduask.dao.StudentDao;
import com.eduask.dao.impl.StudentDaoImpl;
import com.eduask.pojo.Student;
public class StudentTest {
//引入spring中的bean.xml配置文件;
private ClassPathXmlApplicationContext cx=null;
@Before
public void setUp(){
cx=new ClassPathXmlApplicationContext("spring/bean.xml");
}
//增加;
@Test
public void testInsertStudent() throws Exception{
StudentDao studentDao=cx.getBean(StudentDaoImpl.class);
Student student=new Student();
student.setName("link");
student.setPwd("123456");
studentDao.insertStudent(student);
}
//删除
//删除需要获得id，在StudentDaoImpl类中删除方法中调用获得id的方法;
@Test
public void testDeleteStudent() throws Exception{
StudentDao studentDao=cx.getBean(StudentDaoImpl.class);
studentDao.deleteStudent(1);
}
//修改;
//修改需要获得id;
@Test
public void testUpdateStudent() throws Exception{
StudentDao studentDao=cx.getBean(StudentDaoImpl.class);
Student student=new Student();
student=studentDao.getStudentById(2);
student.setPwd("12345678");
studentDao.updateStudent(student);
}
//查询通过id;
@Test
public void testSelectStudent() throws Exception{
StudentDao studentDao=cx.getBean(StudentDaoImpl.class);
System.out.println(studentDao.getStudentById(2));
}
//查询所有;
@Test
public void testSelectAllStudent() throws Exception{
StudentDao studentDao=cx.getBean(StudentDaoImpl.class);
List<Student> students=studentDao.getStudents();
for (Student student : students) {
System.out.println(student);
}

}
}
