Arraylist的一个问题从数据库拿到多组数据但是只能读出一组

这是数据库select方法public List getgameperson() {

    List<Gameperson> list = new ArrayList<Gameperson>();
    Connection conn = null;
    Statement  st = null;
    ResultSet  rs = null;
    try {
        conn = DBO.getconnection();
        st =(Statement) conn.createStatement();
        String  sql = "select *  from gameperson";
        rs = (ResultSet) st.executeQuery(sql);
        if(rs.next()){
            Gameperson gp = new Gameperson();
            gp.setId(rs.getInt("id"));
            gp.setCompetitorId(rs.getInt("competitorId"));
            gp.setGameId(rs.getInt("gameId"));

            list.add(gp);
        }
    } catch (Exception e) {
        // TODO: handle exception
        e.printStackTrace();
    }finally{
        DBO.close(st, rs, conn);
    }
    return list;
}

这是拿出方法：

<%
List list = new ArrayList();
GamepersonDao gpo = new GamepersonDaoImpl();
list = gpo.getgameperson();
if(list!=null){
for (int i=0;i<list.size();i++){
Gameperson gp = list.get(i);
%>
<%=gp.getId()%>

<%=gp.getGameId() %>

<%=gp.getCompetitorId()%>

<%
}
} %>

现在数据库有很多组数据，但是为什么页面只能显示遍历一组？
