简单的MVC模式struts1.2添加hibernate3的问题！！！！
[color=#FF0000]程序本来是单独的struts1.2，在struts.config.xml里配置数据源操作数据库的，现在添加了hibernate3作为持久层来操作数据库。hibernate的配置文件已经配置好了。<session-factory> 和C3P0连接池也弄好了。数据库表的xml文件也创建好了，映射文件也注册了。相应的DAO接口,实现类，都写了。

但是ActionForward不会改了~~~具体代码该怎么写。。。注意是struts1.2的，给几个例子吧。我把我原来的代码发一下，你们看一下怎么改，哪里需要改。

原ActionForward类：

Java code

public class AllNewsAction extends DispatchAction {    public ActionForward addnews(ActionMapping mapping, ActionForm form,            HttpServletRequest request, HttpServletResponse response) {        NewsForm AllNewsActionForm = (NewsForm) form;        try {            Service actionNews = new Service(AllNewsActionForm);            if (((NewsForm) form).getNews_theme().trim().equals("")                    || ( (NewsForm) form).getNews_author().trim().equals("")                    || ((NewsForm) form).getNews_date().trim().equals(""))                throw new Exception("主题，作者，日期，三者不允许为空！");            else {                actionNews.save((NewsForm)form);                request.setAttribute("info", "保存成功！");            }        } catch (Exception e) {            request.setAttribute("info", e.getMessage());        }        return mapping.findForward("save");    }    public ActionForward showall(ActionMapping mapping, ActionForm form,            HttpServletRequest request, HttpServletResponse response) {        NewsForm AllNewsActionForm = (NewsForm) form;        try {            Service actionNews = new Service(AllNewsActionForm);            List<String[]> result = actionNews.search((NewsForm)form);            if (result.size() > 0) {                request.setAttribute("result", result);                request.setAttribute("info_all", "总记录数："                        + String.valueOf(result.size()));            } else                request.setAttribute("info_all", "没有符合要求的记录!");        } catch (Exception e) {            request.setAttribute("info_all", e.getMessage());        }        return mapping.findForward("searchAll");    }

原Service类：

Java code

public class Service {    public NewsForm form;    public Service(NewsForm form) throws Exception {        super();        this.form=form;    }    public List<String[]> search(NewsForm form) throws Exception     {        try{        List<String[]> result = new LinkedList<String[]>();        String sql = "select * from s_news";        SQLBean Bean=new SQLBean();        Bean.searchall(sql,result,form);        Bean.close();         return result;        }        catch (Exception e)         {            throw new Exception(e.getMessage());        }    public void save(NewsForm form) throws Exception {            //封装到JavaBean对象中        try{            String news_theme=form.getNews_theme();            String news_author=form.getNews_author();            String news_date=form.getNews_date();            String news_detail=form.getNews_detail();                    String news_url=form.getNews_url();                            NewsForm bean=new NewsForm();                        bean.setNews_theme(news_theme);            bean.setNews_author(news_author);            bean.setNews_date(news_date);            bean.setNews_detail(news_detail);            bean.setNews_url(news_url);                        String sql="insert into s_news(news_theme,news_author,news_date,news_detail,news_url)values(?,?,?,?,?)";            //调用模型层            SQLBean Bean=new SQLBean();            Bean.add(sql,form);            Bean.close();        } catch (Exception e)         {            throw new Exception(e.getMessage());        }    }            }

原底层SQLbean类：

Java code

public class SQLBean{    public NewsForm form;    public Connection conn;    public PreparedStatement pstat;    public ResultSet rs;    public Statement stat;    public DataSource ds;public void add(String sql,NewsForm form) throws Exception{    try {        this.conn = ds.getConnection();        pstat=conn.prepareStatement(sql);        pstat.setString(1, form.getNews_theme());        pstat.setString(2, form.getNews_author());        pstat.setString(3, form.getNews_date());        pstat.setString(4, form.getNews_detail());        pstat.setString(5, form.getNews_url());        pstat.executeUpdate();         conn.commit();    } catch (Exception e)  {        // TODO 自动生成 catch 块        throw new Exception(e.getMessage());    }    }public  List<String[]> searchall(String sql,List<String[]> result,NewsForm form) throws Exception{    try{        this.conn = ds.getConnection();        pstat=conn.prepareStatement(sql);        ResultSet rs=pstat.executeQuery();        conn.commit();        while(rs.next())        {            String[] row = new String[6];            row[0] = rs.getString(1);            row[1] = rs.getString(2);            row[2] = rs.getString(3);            row[3] = rs.getString(4);            row[4] = rs.getString(5);            row[5] = rs.getString(6);            result.add(row);        }    return result;    } catch (Exception e)  {        // TODO 自动生成 catch 块        throw new Exception(e.getMessage());    }    }

[解决办法]
你个东西代码太长了，没有时间去给你改。。。strust1都忘掉了。。。
给你一个N年前用的strust1的ssh部分代码。。你看懂了就可以改你自己的了。。。

service：
public interface MemberService {
//会员注册
public void save(Member transientInstance);
}
service impl：
