1.导入maven节点  <dependencies>

//测试用的

    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>

      <artifactId> aspectjweaver</artifactId >
      <version> 1.8.7</version >
    </dependency>
//mysql驱动

    <dependency>
      <groupId>org.wisdom-framework</groupId>
      <artifactId>mysql-connector-java</artifactId>
      <version>5.1.34_1</version>
    </dependency>
//c3p0数据源（选用）

    <dependency>
      <groupId>c3p0</groupId>
      <artifactId>c3p0</artifactId>
      <version>0.9.1.2</version>
    </dependency>
//spring事务

    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-tx</artifactId>
      <version>4.3.3.RELEASE</version>
    </dependency>
//sqring核心

    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-context</artifactId>
      <version>4.3.0.RELEASE</version>
    </dependency>
//hibernate核心

    <dependency>
      <groupId>org.hibernate</groupId>
      <artifactId>hibernate-core</artifactId>
      <version>5.2.6.Final</version>
    </dependency>
//spring和hibernate整合相关

    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-orm</artifactId>
      <version> 4.2.2.RELEASE</version>
    </dependency>
//测试

    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>4.11</version>
    </dependency>

  </dependencies>
//用于解决idea读取不到非resource目录下配置文件问题

  <build>
    <resources>
      <resource>
        <directory>src/main/java</directory>
        <includes>
          <include>**/*.*</include>
        </includes>
      </resource>
    </resources>
  </build>

2.建立分层

3.建立实体类Stuck

package cn.lhl.entity;

/**
 * Created by Administrator on 2017/4/2/002.
 */
//股票类

public class Stuck {
//id
    private int sid;
//股票名
    private String sname;
//持股数
    private int scount;
//相关geter，setter
    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;
    }

    public int getScount() {
        return scount;
    }

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

4.创建Stuck的映射文件Stuck.hbm.xml

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
        "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
        "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
<hibernate-mapping package="cn.lhl.entity">
    <class name="Stuck">
        <id name="sid">
            <generator class="native"></generator>
        </id>
        <property name="scount"/>
        <property name="sname"/>
    </class>
</hibernate-mapping>

5.创建dao接口IStuckDao和实现类StuckDaoImpl

package cn.lhl.dao;

import cn.lhl.entity.Stuck;

/**
 * Created by Administrator on 2017/4/4/004.
 */
public interface IStuckDao {
    int addStuck(Stuck stuck);
}

package cn.lhl.dao.impl;

import cn.lhl.dao.IStuckDao;
import cn.lhl.entity.Stuck;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.transaction.annotation.Transactional;

import java.io.Serializable;

/**
 * Created by Administrator on 2017/4/4/004.
 */
public class StuckDaoImpl implements IStuckDao {
//创建session工厂
    private SessionFactory sessionFactory;
//事务注解（执行该方法时打开事务）
    @Transactional
//添加股票的方法
    public int addStuck(Stuck stuck) {
        Session session = sessionFactory.getCurrentSession();
        Serializable save = session.save(stuck);
        return (Integer)save;
    }

    public SessionFactory getSessionFactory() {
        return sessionFactory;
    }

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

6.创建service层接口IStuckService和实现类StuckServiceImpl

package cn.lhl.service;

import cn.lhl.entity.Stuck;

/**
 * Created by Administrator on 2017/4/4/004.
 */
public interface IStuckService {
    int addStuck(Stuck stuck);
}

package cn.lhl.service.impl;

import cn.lhl.dao.IStuckDao;
import cn.lhl.entity.Stuck;
import cn.lhl.service.IStuckService;

/**
 * Created by Administrator on 2017/4/4/004.
 */
public class StuckServiceImpl implements IStuckService {
    private IStuckDao iStuckDao;
    public int addStuck(Stuck stuck) {
        return iStuckDao.addStuck(stuck);
    }

    public IStuckDao getiStuckDao() {
        return iStuckDao;
    }

    public void setiStuckDao(IStuckDao iStuckDao) {
        this.iStuckDao = iStuckDao;
    }
}

7.创建spring配置文件applicationContext.xml<?xml version="1.0" encoding="UTF-8"?<beans xmlns="http://www.springframework.org/schema/beans"

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
       http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd
       http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
    <!--配置数据源-->
    <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource" p:driverClassName="com.mysql.jdbc.Driver" p:url="jdbc:mysql:///gupiao" p:username="root" p:password="qq1684547081">
    </bean>
    <!--配置sessionFactory-->
    <bean name="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
        <!--引入数据源-->
        <property name="dataSource" ref="dataSource"></property>
        <!--设置hibernate相关配置-->
        <property name="hibernateProperties">
            <props>
                <!--sql方言-->
                <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</prop>
                <!--是否显示sql-->
                <prop key="hibernate.show_sql">true</prop>
                <!--设置于线程绑定的session-->
                <prop key="hibernate.current_session_context_class">org.springframework.orm.hibernate5.SpringSessionContext</prop>
                <!--设置自动更新表结构-->
                <prop key="hibernate.hbm2ddl.auto">update</prop>
            </props>
        </property>
        <!--扫描hibernate小配置-->
        <property name="mappingDirectoryLocations" value="classpath:cn/lhl/entity"></property>
    </bean>
    <!--dao代理bean-->
    <bean name="stuckDaoImpl" class="cn.lhl.dao.impl.StuckDaoImpl">
        <!--植入sessionFactory-->
        <property name="sessionFactory" ref="sessionFactory"></property>
    </bean>
    <!--service代理bean-->
    <bean name="stuckService" class="cn.lhl.service.impl.StuckServiceImpl">
        <!--植入dao-->
        <property name="iStuckDao" ref="stuckDaoImpl"></property>
    </bean>
    <!--设置事务管理器-->
    <bean name="transactionManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager">
        <!--引入sessionFactory-->
        <property name="sessionFactory" ref="sessionFactory"></property>
    </bean>
    <!--配置注解事务扫描器-->
    <tx:annotation-driven transaction-manager="transactionManager"></tx:annotation-driven>
</beans>

8.创建测试类

package cn.lhl.test;

import cn.lhl.entity.Stuck;
import cn.lhl.service.impl.StuckServiceImpl;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

/**
 * Created by Administrator on 2017/4/4/004.
 */
public class SSHTest {
    @Test
    public void add(){
        ApplicationContext context=new ClassPathXmlApplicationContext("applicationContext.xml");
        StuckServiceImpl  stuckService=(StuckServiceImpl) context.getBean("stuckService");
        Stuck stuck=new Stuck();
        stuck.setSname("龙骨");
        stuck.setSname("1");
        stuckService.addStuck(stuck);
    }
}

整合完成
