Hibernate+jsp+struts+spring做增删该查,

同样还是web项目，这里只做了一张表，做一个测试，例子。主要是建Hibernate 的时候要非常注意，有时间了整理一下建Hiberbnate 的时候需要注意的事项

这里我是建了5个包，其实只要四个就好，那个service包和action包可以放在一起的，其他的是1.实体包；2.接口包（写方法名的）；3.接口实现包（实现接口的方法）；4.action包（数据逻辑）

一、实体包，这里是自动生成的，但是强迫症还是把它放在这里了啊

 package com.chinasofti.sh2.entity;

 /**
  * Information entity. @author MyEclipse Persistence Tools
  */

 @SuppressWarnings("serial")
 public class Information implements java.io.Serializable {

     // Fields

     private Integer id;
     private String name;
     private String department;
     private String position;
     private String password;
     private String tel;
     private String lervel;

     // Constructors

     /** default constructor */
     public Information() {
     }

     /** full constructor */
     public Information(String name, String department, String position,
             String password, String tel, String lervel) {
         this.name = name;
         this.department = department;
         this.position = position;
         this.password = password;
         this.tel = tel;
         this.lervel = lervel;
     }

     // Property accessors

     public Integer getId() {
         return this.id;
     }

     public void setId(Integer id) {
         this.id = id;
     }

     public String getName() {
         return this.name;
     }

     public void setName(String name) {
         this.name = name;
     }

     public String getDepartment() {
         return this.department;
     }

     public void setDepartment(String department) {
         this.department = department;
     }

     public String getPosition() {
         return this.position;
     }

     public void setPosition(String position) {
         this.position = position;
     }

     public String getPassword() {
         return this.password;
     }

     public void setPassword(String password) {
         this.password = password;
     }

     public String getTel() {
         return this.tel;
     }

     public void setTel(String tel) {
         this.tel = tel;
     }

     public String getLervel() {
         return this.lervel;
     }

     public void setLervel(String lervel) {
         this.lervel = lervel;
     }

 }

Information.java

二、接口包。里面有方法名，可是没有实际的方法

 package com.chinasofti.sh2.dao;

 import java.util.List;

 import com.chinasofti.sh2.entity.Information;

 public interface IInformationDAO {
     void Insert(Information model);
     void Update(Information model);
     void Delete(Information model);
     Information GetInformationById(int id);
     List<Information> GetInformation();
     List<Information>  GetInformationPaging(int pageIndex,int pageSize);
 }

IInformationDAO

三、接口实现包

 package com.chinasofti.sh2.daoimpl;

 import java.util.List;

 import org.hibernate.SessionFactory;
 import org.springframework.orm.hibernate3.HibernateTemplate;

 import com.chinasofti.sh2.dao.IInformationDAO;
 import com.chinasofti.sh2.entity.Information;

 public class InformationImpl implements IInformationDAO{
     private SessionFactory sessionFactory;
     private HibernateTemplate hibernateTemplate;

     public SessionFactory getSessionFactory() {
         return sessionFactory;
     }

     public void setSessionFactory(SessionFactory sessionFactory) {
         this.sessionFactory = sessionFactory;
     }

     public HibernateTemplate getHibernateTemplate() {
         return hibernateTemplate;
     }

     public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {
         this.hibernateTemplate = hibernateTemplate;
     }

     @Override
     public void Insert(Information model) {
         // TODO Auto-generated method stub
         hibernateTemplate.save(model);
     }

     @Override
     public void Update(Information model) {
         // TODO Auto-generated method stub
         hibernateTemplate.update(model);
     }

     @Override
     public void Delete(Information model) {
         // TODO Auto-generated method stub
         hibernateTemplate.delete(model);
     }

     @Override
     public Information GetInformationById(int id) {
         // TODO Auto-generated method stub
         return hibernateTemplate.get(Information.class, id);
     }

     @Override
     public List<Information> GetInformation() {
         // TODO Auto-generated method stub
         return null;
     }

     @Override
     public List<Information> GetInformationPaging(int pageIndex, int pageSize) {
         // TODO Auto-generated method stub
         return this.getHibernateTemplate().loadAll(Information.class).subList((pageIndex-1)*pageSize, pageIndex*pageSize);
     }

 }

InformationImpl.java

四、Action包，处理逻辑问题的,

 package com.chinasofti.sh2.service;

 import org.springframework.context.ApplicationContext;
 import org.springframework.context.support.ClassPathXmlApplicationContext;

 import com.chinasofti.sh2.dao.IInformationDAO;
 import com.chinasofti.sh2.daoimpl.InformationImpl;
 import com.chinasofti.sh2.entity.Information;

 public class InformationService {

     /**
      * @param args
      */
     public static void main(String[] args) {
         // TODO Auto-generated method stub
         ApplicationContext context=new ClassPathXmlApplicationContext("applicationContext.xml");
         InformationImpl ii=(InformationImpl)context.getBean("informationservice");
         //1.增加
 //        Information i=new Information();
 //        i.setName("王二小");
 //        i.setPassword("123123");
 //        i.setLervel("员工");
 //        i.setDepartment("654654");
 //        i.setPosition("4546");
 //        i.setTel("5");
 //        ii.Insert(i);
         //2.删除
 //        Information i=new Information();
 //        i.setName("王二小");
 //        i.setPassword("123123");
 //        i.setLervel("员工");
 //        i.setDepartment("654654");
 //        i.setPosition("4546");
 //        i.setTel("5");
 //        i.setId(31);
 //        ii.Delete(i);

         //3.更改
 //        Information i=new Information();
 //        i.setName("111");
 //        i.setPassword("111");
 //        i.setLervel("111");
 //        i.setDepartment("111");
 //        i.setPosition("111");
 //        i.setTel("111");
 //        i.setId(25);
 //        ii.Update(i);
         //4.根据ID查找

          Information i= ii.GetInformationById(1);
         System.out.println(i.getName()+"."+i.getLervel());
     }

 }

InformationServace.java

 package com.chinasofti.sh2.action;

 import java.util.List;

 import com.chinasofti.sh2.dao.IInformationDAO;
 import com.chinasofti.sh2.entity.Information;

 public class InformationAction {
     private IInformationDAO service;

     private int pageSize=5;//分页的
     private int pageIndex=1; //分页的

     private List<Information> result;

     public IInformationDAO getService() {
         return service;
     }

     public void setService(IInformationDAO service) {
         this.service = service;
     }

     public int getPageSize() {
         return pageSize;
     }

     public void setPageSize(int pageSize) {
         this.pageSize = pageSize;
     }

     public int getPageIndex() {
         return pageIndex;
     }

     public void setPageIndex(int pageIndex) {
         this.pageIndex = pageIndex;
     }

     public List<Information> getResult() {
         return result;
     }

     public void setResult(List<Information> result) {
         this.result = result;
     }

     public String list(){
         //输入输出的检测，要在Action里面写。
         result=service.GetInformationPaging(pageIndex,pageSize);//分页的
         return "list";
     }

 }
