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";
} }
InformationAction.java
五。jsp界面
