自己写的简单的ssh的增删改查demo，用annotation注解的

package com.service; import java.util.List; import javax.annotation.Resource; import org.springframework.orm.hibernate3.HibernateTemplate; import org.springframework.stereotype.Component; import com.entity.Student; @Component public class StudentCrud { @Resource private HibernateTemplate hibernateTemplate; public void saveStudent(Student s) { hibernateTemplate.save(s); }; // public void deleteStudent(Student s){ // hibernateTemplate.delete(s); // }; // 删除 public void deleteStudent(Student s) { System.out.println("dd"+s.getName()); // hibernateTemplate.delete(s); 删除单条必须知道id hibernateTemplate.bulkUpdate("delete Student where name=?", new Object[]{s.getName()});//删除多条 System.out.println("dd11"); } // 更新 public void updateStudent(Student s) { // hibernateTemplate.update(s);//单条必须知道id hibernateTemplate.bulkUpdate("update Student set classnum=? where name=?", new Object[]{s.getClassnum(),s.getName()});//多条 }; // public void findStudent(Student s){ // hibernateTemplate.find("select name from student where name=?"); // }; // 查询 public List getList(String hql, Student s) { List list = hibernateTemplate.find(hql, new Object[]{s.getName()}); /* * list = this.getHibernateTemplate().executeFind( new HibernateCallback() { public Object doInHibernate(Session session) throws HibernateException, SQLException { Query query = session.createQuery(hql); query.setFirstResult(pageNo); query.setMaxResults(pageSize); List list = query.list(); return list; } }); */ return list; } public HibernateTemplate getHibernateTemplate() { return hibernateTemplate; } public void setHibernateTemplate(HibernateTemplate hibernateTemplate) { this.hibernateTemplate = hibernateTemplate; } public StudentCrud() { super(); // TODO Auto-generated constructor stub } }
