001——Spring、Hibernate整合

1.       引入jar包：

2.       根目录下创建spring.xml配置信息： 

3.       建立接口：

package com.sinosoft.manage;

 

public interface UserManage {

  

   public static final String uname="XSY";

  

   public abstract void testHib();

}

4.       实现接口：

package com.sinosoft.manage.impl;

 

import java.util.Iterator;

import java.util.List;

 

import org.hibernate.Session;

import org.hibernate.SessionFactory;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

import org.springframework.stereotype.Service;

 

import com.sinosoft.manage.UserManage;

import com.sinosoft.po.User;

 

@Service

public class UserManageImpl extends HibernateDaoSupport implements UserManage {

 

   @Autowired

   public void setSF(SessionFactory sessionFactory){

            //给父类复制

            setSessionFactory(sessionFactory);

   }

  

   @Override

   public void testHib() {

            //获取父类的方法  hibernate中的

            Session session = getSession();

            List list = session.createQuery(" from User").list();

            for (Iterator iterator = list.iterator(); iterator.hasNext();) {

                     User user = (User) iterator.next();

                     System.out.println(user.getUname());

            }

           

            //三个hibernate特有的方法

//                  List users = getHibernateTemplate().find(" from User");

//                  long count = (Long) getHibernateTemplate().find("select count(*) from User where id < ?",6).get(0);

//                  long count1 = (Long) session.createQuery("select count(*) from User where id < ?").setInteger(0, 6).uniqueResult();

 

            User user = new User();

            user.setUname("xsy");

            session.save(user);

            //发生错误信息   事物回退 不进行提交操作

            int i  = 1/0;

   }

}

5.       建立pojo实体对象：

package com.sinosoft.po;

 

public class User {

   private String uname;

   private String pwd;

   private String sex;

   public User() {

      super();

      // TODO Auto-generated constructor stub

   }

 

   public User(String uname, String pwd, String sex) {

      super();

      this.uname = uname;

      this.pwd = pwd;

      this.sex = sex;

   }

 

   //get set 方法

}

6.  在pojo同一级别创建映射文件 TbUser.hbm.xml

7.  测试：

package test;

 

import org.junit.Test;

import org.springframework.beans.factory.annotation.Autowired;

 

import com.sinosoft.manage.UserManage;

import com.sinosoft.manage.impl.UserManageImpl;

 

public class SpringTest {

 

@Autowired

private UserManage userManage = new UserManageImpl();

 

@Test

public void test(){

    userManage.testHib();

}

}
