案例41-hibernate练习-添加客户

1 utils部分

1 HibernateUtils

package www.test.utils;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;

public class HibernateUtils {

    private static SessionFactory sf;
    static{
        // 1 创建,调用空参构造
        Configuration conf = new Configuration().configure();
        // 2 根据配置信息,创建 SessionFactory对象
        sf = conf.buildSessionFactory();
    }

    // 获得session==>获得全新的session
    public static Session openSession() {
        // 3 获得session
        Session session = sf.openSession();
        return session;
    }
    // 获得session==>获得与线程绑定的session
    public static Session getCurrentSession() {
        // 3 获得session
        Session session = sf.getCurrentSession();
        return session;
    }
    /*public static void main(String[] args) {
        System.out.println(HibernateUtils.openSession());
    }*/
}

2 BeanFactory

package www.test.utils;

import org.dom4j.Document;
import org.dom4j.Element;
import org.dom4j.io.SAXReader;
@SuppressWarnings("all")
public class BeanFactory {

    public static Object getBean(String id){
        //生成对象--根据清单生产--配置文件--将每一个bean对象的生产细节配置到配置文件中

        //使用dom4j的xml解析技术 导入两个jar包
        // dom4j-1.6.1.jar 和 jaxen-1.1-beta-6.jar

        try {
            // 1 创建解析器
            SAXReader reader = new SAXReader();
            // 2 解析文档--bean.xml 在src下面
            String path = BeanFactory.class.getClassLoader().getResource("bean.xml").getPath();
              //读取
            Document doc = reader.read(path);

            // 3 获得元素--参数是xpath规则
            Element element = (Element) doc.selectSingleNode("//bean[@id='"+id+"']");
            //<bean id="adminService" class="www.test.service.impl.AdminServiceImpl"></bean>
            String className = element.attributeValue("class");
            //www.test.service.impl.AdminServiceImpl

            //使用反射创建对象
            Class clazz = Class.forName(className);
            Object object = clazz.getDeclaredConstructor().newInstance();

            return object;

        } catch (Exception e) {

            e.printStackTrace();

        String[] values = parameterMap.get(name);
        if (values == null) {
            return null;

        return values[0]; // 取回参数的第一个值
    }

    @Override

    }

}

package www.test.service;

import www.test.domain.Customer;

public interface CustomerService {

    //保存客户
    void save(Customer customer);

}

2 CustomerServiceImpl实现类

package www.test.service.impl;

public class CustomerServiceImpl implements CustomerService {

    private CustomerDao customerDao = (CustomerDao) BeanFactory.getBean("customerDao");

    @Override
    public void save(Customer customer) {
        //调用Dao保存客户
        customerDao .save(customer);
    }

}

5 Dao层

1 CustomerDao接口

package www.test.dao;

import www.test.domain.Customer;

public interface CustomerDao {

    //保存客户
    void save(Customer customer);

}

2 CustomerDaoImpl实现类

package www.test.dao.impl;

import org.hibernate.Session;
import org.hibernate.Transaction;

import www.test.dao.CustomerDao;
import www.test.domain.Customer;
import www.test.utils.HibernateUtils;

public class CustomerDaoImpl implements CustomerDao {

    @Override
    //保存客户
    public void save(Customer customer) {
        // 1 获得session
        Session session = HibernateUtils.openSession();
        // 2 打开事务
        Transaction transaction = session.beginTransaction();
        // 3执行保存
        session.save(customer);
        // 4提交事务
        transaction.commit();
        // 5关闭资源
        session.close();
    }

}
