通过HbernateTemplate可以简化操作数据库时的代码量：

以下为通过hibernateTemplate实现增删查改

package com.fengqing.dao.impl;import java.util.List;import org.springframework.orm.hibernate3.HibernateTemplate;import com.fengqing.dao.UserDao;import com.fengqing.model.User;public class UserDaoImpl implements UserDao {public HibernateTemplate hibernateTemplate;public HibernateTemplate getHibernateTemplate() {return hibernateTemplate;}public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {this.hibernateTemplate = hibernateTemplate;}//保存@Overridepublic void save(User user) {hibernateTemplate.save(user);}//删除public void delete(int id){Object object = hibernateTemplate.get(User.class, id);hibernateTemplate.delete(object);}@Overridepublic void update(User user) {hibernateTemplate.update(user);}@Overridepublic List<User> getAll() {List<User> list = (List<User>)hibernateTemplate.find("from User");return list;}}

applicationContext.xml中的配置
