Spring和hibernate的整合

1.Bean

package com.zhidi.entity;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;

@Entity
@Table(name="student")
public class Student {
    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    private Integer id;
    private String name;
    private String sex;
    public Integer getId() {
        return id;
    }
    public void setId(Integer id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public String getSex() {
        return sex;
    }
    public void setSex(String sex) {
        this.sex = sex;
    }
    
}

2.Dao

package com.zhidi.dao;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;

import com.zhidi.entity.Student;

@Repository
public class StudentDao {
    @Autowired
    private SessionFactory sessionFactory;
    public Integer save(Student stu)
    {
       Session session=sessionFactory.getCurrentSession();
       //开启事务
       session.beginTransaction();
       Integer in=(Integer)session.save(stu);
       //提交事务
       session.getTransaction().commit();
     
     return in;
    }
}

3.Test

package com.zhidi.test;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.zhidi.dao.StudentDao;
import com.zhidi.entity.Student;

public class Test {

    public static void main(String[] args) {
        ApplicationContext context= new ClassPathXmlApplicationContext("applicationContext.xml");
        Student stu=new Student();
        stu.setName("张全蛋");
        stu.setSex("女");
        //从Spring中获得StudentDao实例
        StudentDao studentDao=context.getBean(StudentDao.class);
        studentDao.save(stu);
        System.out.println(studentDao.save(stu));
        
        
    }
}

4.applicationContext.xml
