3 service层
1 CustomerServie接口
package www.test.service;
import java.util.List;
import www.test.domain.Customer;
public interface CustomerService {
//保存客户
void save(Customer customer);
//获取客户列表
List<Customer> findAllCustomerList();
}
2 CustomerServiceImpl实现类
@Override
//获取客户列表,这里实际上不需要事务控制，只是为了练习而已
public List<Customer> findAllCustomerList() {
//获得session
Session session = HibernateUtils.getCurrentSession();
//控制事务
Transaction transaction = session.beginTransaction();
List<Customer> customerList =null;
try {
//调用dao层获取客户列表
customerList = dao.findAllCustomerList();
} catch (Exception e) {
e.printStackTrace();
transaction.rollback();
}finally{
transaction.commit();
}
4 dao层
1 CustomerDao接口
package www.test.dao;
import java.util.List;
import www.test.domain.Customer;
public interface CustomerDao {
//保存客户
void save(Customer customer);
//获取客户列表
List<Customer> findAllCustomerList();
}
2 CustomerDaoImpl实现类
@Override
//获取客户列表
public List<Customer> findAllCustomerList() {
//获得session
Session session = HibernateUtils.getCurrentSession();
//创建执行者对象
Criteria criteria = session.createCriteria(Customer.class);
//执行操作
List<Customer> list = criteria.list();
return list;
}
5 再次复习记忆
1 BaseServlet
package www.test.web.servlet;
import java.io.IOException;
import java.lang.reflect.Method;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
@SuppressWarnings("all")
public class BaseServlet extends HttpServlet {
@Override
protected void service(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
//解决乱码问题
resp.setContentType("text/html;charset=UTF-8");
try {
// 1 获得请求的method方法
String methodName = req.getParameter("method");
// 2获得当前被访问的对象的字节码对象
Class clazz = this.getClass(); //ProductServlet.class --- UserServlet.class
// 3 获取当前字节码对象中指定的方法
Method method = clazz.getMethod(methodName,HttpServletRequest.class,HttpServletResponse.class);
// 4 执行相应的方法
method.invoke(this,req,resp);
} catch (Exception e) {
e.printStackTrace();
}
}
}
2 BeanFactory工具类
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();
}
return null;
}
}
