Spring+SpringMVC+Hibernate整合注解版

这次是Spring+SpringMVC+Hibernate整合的注解版

   结果目录如下：

 

 bean层：

  Student：

package cn.happy.bean;import javax.persistence.*;/** * Created by lenovo on 2017/10/13. */@Entity@Table(name = "studentnew")public class Student {    @Id    @GeneratedValue    private int sid;    @Column    private String sname;    public int getSid() {        return sid;    }    public void setSid(int sid) {        this.sid = sid;    }    public String getSname() {        return sname;    }    public void setSname(String sname) {        this.sname = sname;    }}

controller层：

 StudentCTR：

package cn.happy.controller;import cn.happy.bean.Student;import cn.happy.service.StudentService;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import javax.annotation.Resource;/** * Created by lenovo on 2017/10/13. */@Controllerpublic class StudentCTR {    @Resource(name = "studentService")    private StudentService studentService;    @RequestMapping("/add")    public String add(Student student){               studentService.add(student);        return "index";    }}

dao层：

  StudentDao：

  

package cn.happy.dao;import cn.happy.bean.Student;import org.hibernate.Session;/** * Created by lenovo on 2017/10/13. */public interface StudentDao {    public int add(Student student);}

  StudentDaoImpl：

package cn.happy.dao;import cn.happy.bean.Student;import org.hibernate.Session;import org.hibernate.SessionFactory;import org.springframework.stereotype.Repository;import javax.annotation.Resource;import java.io.Serializable;/** * Created by lenovo on 2017/10/13. */@Repository("studentdao")public class StudnetDaoImpl implements StudentDao {@Resourceprivate SessionFactory sessionFactory;    public int add(Student student) {        Serializable s=sessionFactory.getCurrentSession().save(student);        return (Integer) s;    }}

service：

StudentService：

package cn.happy.service;import cn.happy.bean.Student;/** * Created by lenovo on 2017/10/13. */public interface StudentService {    public int add(Student student);}

StudentServiceImpl：

package cn.happy.service;import cn.happy.dao.StudentDao;import cn.happy.bean.Student;import org.hibernate.Session;import org.hibernate.SessionFactory;import org.springframework.stereotype.Service;import org.springframework.transaction.annotation.Transactional;import javax.annotation.Resource;/** * Created by lenovo on 2017/10/13. */@Service("studentService")public class StudentServiceImpl implements StudentService {    @Resource(name = "studentdao")    private StudentDao dao;    @Transactional    public int add(Student student) {        int result=dao.add(student);        return result;    }    public StudentDao getDao() {        return dao;    }    public void setDao(StudentDao dao) {        this.dao = dao;    }}

applicationContext.xml：

其他和之前没什么不同，就省略了。
