排球比赛计分系统

Posted 2020-09-07

一、设计思路

计分系统根据不同角色拥有不同的界面和展示效果：

1.管理员-----用户管理，赛事管理，赛事记录，队伍管理

2.比赛主办方-------赛事管理，队伍管理

3.裁判--------赛事记录

其他人员在管理员未分配权限时不具有任何权限，只能观看比赛信息

运用Struts2和hibernate框架，进行数据视图交互

二、代码部分（比赛计分，信息展示部分）

1.GamesDaoImpl.java

package com.dao.impl;

import java.util.List;

import org.hibernate.HibernateException;
import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.Transaction;

import com.bean.GamesInfo;
import com.bean.GamesNotice;
import com.bean.Users;
import com.dao.BaseDao;
import com.dao.GamesDao;

public class GamesDaoImpl extends BaseDao implements GamesDao {
/*
 * 插入比赛计分信息*/
    public boolean saveGames(GamesInfo games) {
        Session session=null;
        Transaction tr=null;
        try {
            session=getSession();
            tr=session.beginTransaction();
            session.save(games);
            tr.commit();
        } catch (HibernateException e) {
            e.printStackTrace();
            tr.rollback();
            return false;
        }finally{
            closeSession();
        }
        return true;
    }
    /*
     * 插入比赛计分信息成功更新赛事信息*/
    public boolean updateGames(GamesNotice gamesNotice) {
        Session session=null;
        Transaction tr=null;
        try {
            session=getSession();
            tr=session.beginTransaction();
            session.update(gamesNotice);
            tr.commit();
        } catch (HibernateException e) {
            e.printStackTrace();
            tr.rollback();
            return false;
        }finally{
            closeSession();
        }
        return true;
    }
    /*
     * 观看比赛计分信息，模糊查询*/
    public List<GamesInfo> SalChanceList(String Title) {
        List<GamesInfo> SalChanceList=null;
        Session session=null;
        Transaction tr=null;
        try {
            session = getSession();
            tr = session.beginTransaction();
            StringBuffer hql=new StringBuffer();
            hql.append("from GamesInfo where 1=1");
            if (!"".equals(Title)) {
                hql.append(" and GTitle like ‘%"+Title+"%‘ ");
            }
            Query query=session.createQuery(hql.toString());
            query.setFirstResult(1);
            query.setMaxResults(8);
            SalChanceList=query.list();
            tr.commit();
        } catch (Exception e) {
            tr.rollback();
        }
        return SalChanceList;
    }
/*
     * 根据id查询赛事信息*/
    public GamesNotice selectGamesNotice(int id) {
        GamesNotice gamesNotice=null;
        Session session=null;
        try {
            session=getSession();
            String hql="from GamesNotice where NId=?";
            Query query=session.createQuery(hql);
            query.setInteger(0, id);
            List<GamesNotice> list=query.list();
            if(list.size()>0){
                gamesNotice=list.get(0);
            }
        } catch (HibernateException e) {
            e.printStackTrace();
        }finally{
            closeSession();
        }
        return gamesNotice;
    }
    /*
     * 新建赛事信息*/
    public boolean saveGamesNotice(GamesNotice gamesNotice) {
        Session session=null;
        Transaction tr=null;
        try {
            session=getSession();
            tr=session.beginTransaction();
            session.save(gamesNotice);

        }finally{
            closeSession();
        }
        return true;
    }
}

2.gamesAction.java
