SSH程序框架之Spring与HIbernate整合

spring整合hibernate 有两种方式 1、注解方式 2、xml方式实现

　　Spring整合Hibernate有什么好处？

　　1、由IOC容器来管理Hibernate的SessionFactory

　　2、让Hibernate使用上Spring的声明式事务

1.xml方式：

   大概架构：                                 

                                  

我们将会创建一个账户类，实现添加的功能 

首先先添加Spring 和 HIbernate的jar包节点：

 <dependencies>
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.3</version>
            <scope>test</scope>
        </dependency>

        <!--jta的jar包-->
        <dependency>
            <groupId>javax.transaction</groupId>
            <artifactId>jta</artifactId>
            <version>1.1</version>
        </dependency>

        <!--mysql数据库驱动-->
        <dependency>
            <groupId>org.wisdom-framework</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>5.1.34_1</version>
        </dependency>

        <dependency>
            <groupId>org.hibernate</groupId>
            <artifactId>hibernate-core</artifactId>
            <version>5.0.6.Final</version>
        </dependency>

        <!--以上是HIbernate的jar包配置-->

        <!--下面是Spring相关的jar包配置-->
        <!--c3p0-->
        <dependency>
            <groupId>com.mchange</groupId>
            <artifactId>c3p0</artifactId>
            <version>0.9.5.2</version>
        </dependency>

        <!--AOP的相关jar-->
        <dependency>
            <groupId> org.aspectj</groupId >
            <artifactId> aspectjweaver</artifactId >
            <version> 1.8.7</version >
        </dependency>

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context</artifactId>
            <version>4.2.0.RELEASE</version>
        </dependency>

        <!--Spring-ORM-->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-orm</artifactId>
            <version> 4.2.2.RELEASE</version>
        </dependency>
        
    </dependencies>

Stock(账户类)：

package cn.happy.beans;

/**
 * 股票类
 * Created by CKW on 2017/4/2.
 */
public class Stock {
    private Integer sid;//编号
    private String sname;//名称
    private Integer scount;//余额股

    public Stock(String sname, Integer scount) {
        this.sname = sname;
        this.scount = scount;
    }

    public Integer getSid() {
        return sid;
    }

    public void setSid(Integer sid) {
        this.sid = sid;
    }

    public String getSname() {
        return sname;
    }

    public void setSname(String sname) {
        this.sname = sname;
    }

    public Integer getScount() {
        return scount;
    }

    public void setScount(Integer scount) {
        this.scount = scount;
    }
}

dao层接口(StockDao)：

package cn.happy.dao;


import cn.happy.beans.Stock;

/**
 * Created by CKW on 2017/4/2.
 */
public interface StockDao {
    //添加
    public int addStock(Stock stock);
}

dao层实现类(StockDaoImpl)：

package cn.happy.dao.impl;


import cn.happy.beans.Stock;
import cn.happy.dao.StockDao;
import org.hibernate.Session;
import org.hibernate.SessionFactory;

import java.io.Serializable;

/**
 * Created by CKW on 2017/4/2.
 */

public class StockDaoImpl implements StockDao {

    //植入一个工厂对象
    private SessionFactory sessionFactory;

    public int addStock(Stock stock) {
        Session session = sessionFactory.getCurrentSession();
        Serializable count = session.save(stock);
        return (Integer)count;
    }

    public SessionFactory getSessionFactory() {
        return sessionFactory;
    }

    public void setSessionFactory(SessionFactory sessionFactory) {
        this.sessionFactory = sessionFactory;
    }
}

service层接口(AccountService)：

package cn.happy.service;


import cn.happy.beans.Stock;

/**
 * Created by CKW on 2017/4/2.
 */
public interface AccountService {

    //添加
    public int addStock(Stock stock);

}

service层实现类()：

package cn.happy.service.impl;



import cn.happy.beans.Stock;
import cn.happy.dao.StockDao;
import cn.happy.service.AccountService;

import org.springframework.transaction.annotation.Transactional;

/**
 * Created by CKW on 2017/4/2.
 */
public class AccountServiceImpl implements AccountService {
    private StockDao stockDao;

    @Transactional
    public int addStock(Stock stock) {
        return stockDao.addStock(stock);
    }

    public StockDao getStockDao() {
        return stockDao;
    }

    public void setStockDao(StockDao stockDao) {
        this.stockDao = stockDao;
    }
}
