1、首先創(chuàng)建封裝Hibernate的Dao類

import java.io.Serializable;
import java.util.List;

import javax.annotation.Resource;

import org.springframework.orm.hibernate5.HibernateTemplate;
import org.springframework.stereotype.Component;

@Component
public class UserDao<T> {
?? ?
?? ?@Resource(name="hibernateTemplate")
?? ?private HibernateTemplate hibernateTemplate;
?? ?
?? ?public void add(Object o){
?? ??? ?hibernateTemplate.save(o);
?? ?}
?? ?public List<T> select(String ?hql){
?? ??? ?List<T> stus=(List<T>) hibernateTemplate.find(hql);
?? ??? ?return stus;
?? ?}
?? ?
?? ?public Object get(Class clazz,Serializable id) {
?? ??? ?Object obj = hibernateTemplate.get(clazz, id);
?? ??? ?return obj;
?? ?}
?? ?public Object getbyid(Class class1,Long id){
?? ??? ?Object object = hibernateTemplate.get(class1, id);
?? ??? ?return object;
?? ?}
?? ?
?? ?public void delete(Class clazz,Serializable id) {
?? ??? ?hibernateTemplate.delete(this.get(clazz, id));
?? ?}
?? ?
?? ?public void update(Object o) {
?? ??? ?hibernateTemplate.update(o);
?? ?}
?? ?
}

2、中間服務類

import java.util.List;

import javax.annotation.Resource;

import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import com.ssh.bean.Student;
import com.ssh.bean.Userinfodz;
import com.ssh.dao.UserDao;

@Transactional
@Service
public class UserService {
?? ?
?? ?@Resource(name="userDao")
?? ?private UserDao userDao;
?? ?
?? ?public void add(Student stu){
?? ??? ?userDao.add(stu);
?? ?}
?? ?
?? ?public List<Student> showUser(){
//?? ??? ?List<Student> stus = userDao.select("from Student");//查詢所有
?? ??? ?List<Student> stus = userDao.select("from Student where pword LIKE ?'%1%'");//條件查詢
?? ??? ?/*users=(List<Student>)hibernateTemplate.find("from User where uname=?","秦維");*/
?? ??? ?return stus;
?? ?}
?? ?public List<Userinfodz> showinfo(){
?? ??? ?
?? ??? ?List<Userinfodz> inList = userDao.select("from Userinfodz");
?? ??? ?
?? ??? ?return inList;
?? ?}
?? ?public Userinfodz getobjUserinfodzbyid (Long ab){
?? ??? ?Userinfodz userinfodz = (Userinfodz) userDao.getbyid(Userinfodz.class,ab );
?? ??? ?
?? ??? ?return userinfodz;
?? ?}
?? ?public void adduserinfo(Userinfodz userinfodz){
?? ??? ?userDao.add(userinfodz);
?? ?}
}

3、測試類：

?? ?@Resource(name="userService")
?? ?private UserService userService;

Userinfodz userinfodz2 = userService.getobjUserinfodzbyid(11L);

（1）、查詢

//?? ??? ?List<Student> stus = userDao.select("from Student");//查詢所有
?? ??? ?List<Student> stus = userDao.select("from Student where pword LIKE ?'%1%'");//條件查詢

?

根據(jù)id查詢

?? ?public Userinfodz getobjUserinfodzbyid (Long ab){
?? ??? ?Userinfodz userinfodz = (Userinfodz) userDao.getbyid(Userinfodz.class,ab );
?? ??? ?
?? ??? ?return userinfodz;
?? ?}

（2）、插入數(shù)據(jù)

?? ??? ?Userinfodz userinfodz = new Userinfodz();
?? ??? ?userinfodz.setUsername("sqlname");
?? ??? ?userinfodz.setUserno(999);
?? ??? ?userinfodz.setUserpwd("sqlpwd");
?? ??? ?userService.adduserinfo(userinfodz);

@Resource(name="hibernateTemplate")
?? ?private HibernateTemplate hibernateTemplate;

hibernateTemplate.save(userinfodz);

（3）刪除數(shù)據(jù)

dao方法

?? ?public Object getbyid(Class class1,Long id){
?? ??? ?Object object = hibernateTemplate.get(class1, id);
?? ??? ?return object;
?? ?}
?? ?
?? ?public void deletebyid(Class class1,Long id){
?? ??? ?hibernateTemplate.delete(this.getbyid(class1, id));
?? ?}

中間服務

?? ?public void deletebyid(Long ab){
?? ??? ?userDao.deletebyid(Userinfodz.class, ab);
?? ?}

測試

userService.deletebyid(10L);

（4）修改數(shù)據(jù)

?? ?public void updatebyid(Class class1,String uname,String upwd,Long id){
?? ??? ?Userinfodz userinfodz = (Userinfodz) this.getbyid(class1,id );
?? ??? ?userinfodz.setUsername(uname);
?? ??? ?userinfodz.setUserpwd(upwd);
?? ??? ?hibernateTemplate.update(userinfodz);
?? ?}

?? ?public void updatebyid(Class class1,String uname,String upwd,Long id){
?? ??? ?userDao.updatebyid(class1,uname,upwd, id);
?? ?}

userService.updatebyid(Userinfodz.class,"修改的銘2","修改的pwd2", 7L);

?

?
