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 SalChanceList(String Title) { List 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 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); tr.commit(); } catch (HibernateException e) { e.printStackTrace(); tr.rollback(); return false; }finally{ closeSession(); } return true; } }

2.gamesAction.java

package com.action; import javax.servlet.http.HttpSession; import org.apache.struts2.ServletActionContext; import com.bean.GamesInfo; import com.bean.GamesNotice; import com.dao.GamesDao; import com.dao.impl.GamesDaoImpl; import com.opensymphony.xwork2.ActionSupport; public class gamesAction extends ActionSupport { private GamesInfo games;//计分信息类 private GamesNotice gamesNotice;//赛事信息类 public String addGames() { GamesDao gamesDao=new GamesDaoImpl(); //拿到赛事表id查询title int id=Integer.parseInt(games.getGTitle()); GamesNotice gamesNotice=gamesDao.selectGamesNotice(id); games.setGTitle(gamesNotice.getNName()); //比赛信息数据写入数据库 boolean flag=gamesDao.saveGames(games); if(flag=true){ //执行成功,相应的赛事状态为2已比赛完成 gamesNotice.setTState(2); gamesDao.updateGames(gamesNotice); return SUCCESS; }else { return "error"; } } public String NoticeAdd(){ GamesDao gamesDao=new GamesDaoImpl(); //添加赛事 boolean flag=gamesDao.saveGamesNotice(gamesNotice); if(flag=true){ return SUCCESS; }else { return ERROR; } } public GamesInfo getGames() { return games; } public void setGames(GamesInfo games) { this.games = games; } public GamesNotice getGamesNotice() { return gamesNotice; } public void setGamesNotice(GamesNotice gamesNotice) { this.gamesNotice = gamesNotice; } }

3.js方法
