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
