Struts+Hibernate+Sprint结合完美实现
实现接口类：
package com.wu.dao;
import java.util.List;
import hib.*;
import org.springframework.orm.hibernate3.support.*;
public class EmailDAOImp extends HibernateDaoSupport implements IEmailDAO {
org.springframework.orm.hibernate3.LocalSessionFactoryBean sessionFactory;
/*
* (non-Javadoc)
* @see com.wu.dao.IEmailDAO#deleteE(int)
* deleteE方法删除数据 按编号删除
*/
public boolean deleteE(int emailId){
try{
/*
* load方法加载类。 通过这个对象找到这个编号
* 调用模版的delete方法 （删除的是个对象）
*/
EmailInfo obj=(EmailInfo)this.getHibernateTemplate().load(EmailInfo.class, new Integer(emailId));
this.getHibernateTemplate().delete(obj);
return true;
}catch(Exception ex){
System.out.println(ex.getMessage());
return false;
}
}
/*
* (non-Javadoc)
* @see com.wu.dao.IEmailDAO#readAllEmail()
* 读取方法 用模版的find方法
*/
public List readAllEmail(){
try{
String strSql="from hib.EmailInfo";
return this.getHibernateTemplate().find(strSql);
}catch(Exception ex){
System.out.println(ex.getMessage());
return null;
}
}
/*
* (non-Javadoc)
* @see com.wu.dao.IEmailDAO#addEmail(java.lang.String, java.lang.String, java.lang.String, java.lang.String)
* 添加方法 调用用对象来添加
* 添加的模版用Save方法来保存
*/
public boolean addEmail(String emailfrom, String emailto,
String emailtitle, String emailcontent) {
try{
EmailInfo email = new EmailInfo();
email.setEmailfrom(emailfrom);
email.setEmailto(emailto);
email.setEmailtitle(emailtitle);
email.setEmailcontent(emailcontent);
FJInfo fj = new FJInfo();
fj.setFjfile("one");
fj.setFjurl("one");
FJInfo fj1 = new FJInfo();
fj1.setFjfile("two");
fj1.setFjurl("two");
email.getFjSet().add(fj);
email.getFjSet().add(fj1);
this.getHibernateTemplate().save(email);
return true;
}catch(Exception ex){
System.out.println(ex.getMessage());
}
return false;
}
}

Action类
public ActionForward insertEmail(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
EmaiForm emaiForm = (EmaiForm) form;// TODO Auto-generated method stub
String emailfrom = emaiForm.getEmailfrom();
String emailto = emaiForm.getEmailto();
String emailtitle = emaiForm.getEmailtitle();
String emailcontent = emaiForm.getEmailcontent();
/*
* addEmail 添加的方法
* List 添加后要返回一个集合
*/
if(emailDAO.addEmail(emailfrom, emailto, emailtitle, emailcontent)){
List email = emailDAO.readAllEmail();//把添加后的结果显示出来调用这个方法
emaiForm.setList(email);
return mapping.findForward("emailpage");
}else{
return mapping.findForward("errorpage");
}
}
public ActionForward deleteEmail(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
EmaiForm emaiForm = (EmaiForm) form;// TODO Auto-generated method stub
int emailId =Integer.parseInt(request.getParameter("emailId"));
/*
* deleteE 删除的方法
* List 删除后要返回一个集合
*/
if(emailDAO.deleteE(emailId)){
List email = emailDAO.readAllEmail();//删除后要把删除后的结果显示出来
emaiForm.setList(email);
return mapping.findForward("emailpage");
}else{
return mapping.findForward("errorpage");
}

1 楼 zhkchi 2008-02-02 这个。。。你没发现少很多重要的配置说明么？ 2 楼 yojiwei 2008-02-03 没有层次感，写的太乱！
注释的不专业！有待提高！
