一、根据第一节项目稍作修改即可,看截图需要修改的地方。???
?
?二、按画红线处依次贴出代码
UserDAOImpl.java
?
package com.iskyshop.dao.impl; import javax.annotation.Resource; import org.hibernate.Session; import org.hibernate.SessionFactory; import org.springframework.stereotype.Component; import com.iskyshop.dao.UserDAO; import com.iskyshop.model.User; @Component public class UserDAOImpl implements UserDAO { @Resource private SessionFactory sessionFactory; public SessionFactory getSessionFactory() { return sessionFactory; } public void setSessionFactory(SessionFactory sessionFactory) { this.sessionFactory = sessionFactory; } @Override public void saveUser(User user) { // TODO Auto-generated method stub Session session = sessionFactory.getCurrentSession(); session.save(user); // Session session = sessionFactory.openSession(); // session.beginTransaction(); // session.save(user); // session.getTransaction().commit(); } }
?UserServiceImpl.java
?
package com.iskyshop.service.impl; import javax.annotation.Resource; import org.springframework.stereotype.Service; import org.springframework.transaction.annotation.Transactional; import com.iskyshop.dao.UserDAO; import com.iskyshop.model.User; import com.iskyshop.service.UserService; @Service @Transactional public class UserServiceImpl implements UserService{ @Resource private UserDAO userDAO; public UserDAO getUserDAO() { return userDAO; } public void setUserDAO(UserDAO userDAO) { this.userDAO = userDAO; } @Override public void saveUser(User user) { // TODO Auto-generated method stub userDAO.saveUser(user); } }
?Test.java
package com.iskyshop.test; import java.util.Date; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; import com.iskyshop.model.User; import com.iskyshop.service.UserService; public class Test { public static void main(String args[]){ ApplicationContext ctx = new ClassPathXmlApplicationContext("beans.xml"); //因为动态代理是根据接口来动态生成 如果使用转换 会导致方法的丢失,所以下边这段代码应改为。 //UserServiceImpl usi = (UserServiceImpl) ctx.getBean("userServiceImpl"); UserService usi = (UserService) ctx.getBean("userServiceImpl"); User user = new User(); user.setUsername("iskyshop"); user.setPassword("www.iskyshop.com"); user.setAddTime(new Date()); usi.saveUser(user); } }
