    任务:实现图片在linux上根据时间来切换

                

    public boolean findByWinter() throws IOException {// SELECT
    // IssueUserNo,Pic
    Boolean picType = false; // FROM
    // T_BgGraph
    // where PicID=1 /eyou/ui/image/
    String sql = "select Top 1 * from T_BgGraph WHERE TYPE=1 AND ImageShow=4 order by UpdTime desc";
    Connection conn = null;
    conn = DBUtils.getConnection();
    try {
    p = conn.prepareStatement(sql);
    rs = p.executeQuery();

    while (rs.next()) {
    FileOutputStream newFile = new FileOutputStream("/home/aa/EYou/image/4.jpg");
    //FileOutputStream newFile = new FileOutputStream("eyou/ui/image/"+winter+Type);
    Filte(newFile);
    }

    } catch (SQLException e) {
    e.printStackTrace();
    } finally {
    DBUtils.closeCon();
    }
    return picType;

            将图片以流的形式,存进去,再将流下载出来,当时是用SQL Server 数据库中的image 类型对图片进行存储
