ajax第二课.docVIP

第二课 ssh+jquery的easyUI框架实现ajax分页显示及CRUD 数据库和表准备如下: create database mydb go use mydb go create table admin( aid int identity primary key, aname varchar(50), passwd varchar(50) ) select * from admin 建立web工程引入struts.2+spring2.5+hibernate3.3的组件包(步骤参考前面课程的讲解) 生成POJO和DAO类，改写dao类中的方法，代码如下: package com.dao; import java.util.List; import org.hibernate.LockMode; import org.hibernate.Query; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.context.ApplicationContext; import org.springframework.orm.hibernate3.support.HibernateDaoSupport; import com.po.Admin; /** * A data access object (DAO) providing persistence and search support for Admin * entities. Transaction control of the save(), update() and delete() operations * can directly support Spring container-managed transactions or they can be * augmented to handle user-managed Spring transactions. Each of these methods * provides additional information for how to configure it for the desired type * of transaction control. * * @see com.po.Admin * @author MyEclipse Persistence Tools */ public class AdminDAO extends HibernateDaoSupport { private static final Logger log = LoggerFactory.getLogger(AdminDAO.class); // property constants public static final String ANAME = aname; public static final String PASSWD = passwd; protected void initDao() { // do nothing } public void save(Admin transientInstance) { log.debug(saving Admin instance); try { getHibernateTemplate().save(transientInstance); log.debug(save successful); } catch (RuntimeException re) { log.error(save failed, re); throw re; } } public void delete(Admin persistentInstance) { log.debug(deleting Admin instance); try { getHibernateTemplate().delete(persistentInstance); log.debug(delete successful); } catch (RuntimeException re) { log.error(delete failed, re); throw re; } } public Admin findById(java.lang.Integer id) { log.debug(getting Admin instance with id: + id);
