SpringMVC事务配置.docVIP

Spring MVC事务配置 要了解事务配置的所有方法，请看一下《Spring事务配置的5种方法》 本文介绍两种配置方法： ? 一、????? XML，使用tx标签配置拦截器实现事务 一、????? Annotation方式 以下所使用环境为Spring4.0.3、Hibernate4.3.5 ? 一、????? XML，使用tx标签配置拦截器实现事务 Entity类User.java，持久化类，对应数据库表user package com.lei.demo.entity; import javax.persistence.*; @Entity(name=users) public class Users { public Users(){ super(); } @Id @GeneratedValue(strategy=GenerationType.AUTO) @Column(name=id) private Integer id; @Column(name=user_name,length=32) private String user_name; @Column(name=age) private Integer age; @Column(name=nice_name,length=32) private String nice_name; //属性实现...... } ? UserDAO.javar，表user的一些操作，其中属性sessionFactory应该由Spring注入，如下： package com.lei.demo.dao; import java.util.List; import javax.annotation.Resource; import org.hibernate.Query; import org.hibernate.Session; import org.hibernate.SessionFactory; import org.springframework.stereotype.Repository; import com.lei.demo.entity.Users; public class UsersDAO { private SessionFactory sessionFactory; public void setSessionFactory(SessionFactory sessionFactory) { this.sessionFactory = sessionFactory; } public SessionFactory getSessionFactory() { return sessionFactory; } public ListUsers getAllUser(){ String hsql=from users; Session session = sessionFactory.getCurrentSession(); Query query = session.createQuery(hsql); return query.list(); } } ? UserService.java，业务实现类，如下 package com.lei.demo.service; import javax.annotation.Resource; import org.springframework.stereotype.Service; import org.springframework.transaction.annotation.Isolation; import org.springframework.transaction.annotation.Propagation; import org.springframework.transaction.annotation.Transactional; import com.lei.demo.dao.*; public class UserService { private UsersDAO userDao; public int userCount(){ return userDao.getAllUser().size(); }
