本項目為連鎖店餐飲系統。前台C#，伺服器采用Java開發，oracle資料庫；通過webservice實作前背景的互動，背景以提供服務的方式，供前端調用并進行資料庫操作。
商家根據餐飲副食店實際情況提出了新的需求，希望能夠通過在店内放置觸摸屏的方式，使會員顧客能夠以觸摸屏的方式選擇商品并放入自己的購物車，之後售貨員隻需要讀取卡内的購物車資訊即可刷卡消費，這樣大大節約了顧客挑選商品的時間，使整個購物流程并行化程度提高。由于顧客消費的時間大多集中在早中晚，并行化會使店内的銷售量顯著提高。
經過一周的時間終于完成了子產品的更新，下面我将分4個方面詳細的描述整個流程，并附上關鍵部分源碼，分享給大家共同學習。
1.功能子產品介紹；2，觸屏設定實作（前台、伺服器、資料庫）；3，觸屏顯示實作；4，觸屏結算實作
一 功能子產品介紹：
展櫃設定（包括4個子子產品）
1.1 觸屏設定（管理者操作）
本子子產品包括4項功能:
——選擇：根據門店編号mdbh從資料庫消費記錄表和物料表中擷取外賣記錄，顯示在combox中；
——插入：管理者從combox中選取要顯示的商品圖檔，擷取該圖檔的絕對路徑，以記錄的方式插入到config.txt文本中，每個圖檔代表一條記錄
——删除：删除TXT文檔中對應的條目。
——儲存：将目前Imagelistview中的商品圖檔資訊儲存成TXT文檔，存儲在項目的指定目錄下。
1.2 觸屏顯示（顧客操作）
本子產品中，自動加載“觸屏設定”中儲存的TXT文檔，讀取其中的記錄并将對應的圖檔全屏顯示；輕按兩下圖檔會進入商品細節頁面，在本界面，顧客可以選擇”加入購物車“或”傳回“，本頁面能夠顯示庫存量，若庫存量《0，點選傳回後對應圖檔将顯示售罄。
同時設定兩個按鈕“上一頁”，“下一頁”，通過點選可以實作翻頁檢視。
（注：顧客通過本顯示屏可以看到本店内所有的商品資訊，并有選擇的加入到自己卡的購物車中）
1.3 觸屏結算（售貨員操作）
本子產品包括3項功能：
——讀卡：售貨員點選“讀卡”，系統将卡内的購物車資訊顯示在購物車欄中；
——修改：删除菜品：售貨員可以對購物車中的商品調整數量或删除
——結算：對IC卡的購物車商品結算，同時删除資料庫中對應的購物車資訊，執行卡金額操作，并列印發票。
1.4 圖檔下載下傳（管理者操作）
通過FTP的方式，管理者可以從指定的FTP目錄中選擇圖檔，加入本門店的圖檔庫中，供展櫃設定使用。
總體界面設計：
1.5 總體流程：
前台：主要是畫界面，寫webservice調用方法，邏輯實作；
伺服器端：若無對應的服務，則注冊webservice服務（1.在sun-jaxws.xml 中通過endpoint注冊；2.在對應的服務中加入注解，@webservice和@HandlerChain和@webMethod，注意名字要和xml中對應;注冊完服務之後，通過具體的方法執行Sql語句操作資料庫，回報到前台，顯示。
當思路清晰、宏觀設計之後，具體的實作就是搬磚的過程，我們隻需要一步步的根據需求完成子產品即可。Let’s go!
二 觸屏設定
2.1界面設計：
2.2自動加載物料表，Combox顯示
1.通過調用getYLData方法從資料庫中擷取物料資料存入List中
private void initYL(String lb)
{
物料編号.Visible = true;
ylComb.Visible = true;
ylAddBtn.Visible = true;
getYLData(lb); //設定物料表ylList
if (ylList != null)
{
foreach (DataBean bean in ylList)
{
//物料清單
this.ylComb.Items.Add(bean.GetValue("WL_WLBH") + "|" + bean.GetValue("WL_WLMC") + "|" + bean.GetValue("WL_3lMC") + "|" + bean.GetValue("WL_JLDW") + "|" + bean.GetValue("SL"));
}
}
}
2．通過webservice調取服務MaterialService中的getDataFromXSJL方法擷取物料資料，存入ArrayList中。
private void getYLData(string ALMC)
{
ServiceDelegate serviceDelegate = ServiceDelegateFactory.Instance();
//ArrayList materialList = new ArrayList();
try
{
ylList = (ArrayList)serviceDelegate.CommonInvoke("MaterialService", "getDataFromXSJL", ALMC);
}
catch (Exception ex)
{
if (ex is WebServiceException)
{
if ((ex as WebServiceException).ExceptionType ==
EnumDefine.WebServiceException.ConnectException)
{
PopMessage.Error("EXC0009E", ConfigUtil.GetItemValue("ErrorMessageTitle"));
}
else
{
PopMessage.Error("EXC0006E", ConfigUtil.GetItemValue("ErrorMessageTitle"));
}
}
else
{
throw ex;
}
return;
}
if (serviceDelegate.MessageList != null)
{
ServiceMessageBean popMessage = (ServiceMessageBean)serviceDelegate.MessageList[0];
if (popMessage.Parameters != null)
{
PopMessage.Error(popMessage.MessageCode, ConfigUtil.GetItemValue("ErrorMessageTitle"), popMessage.Parameters);
}
else
{
PopMessage.Error(popMessage.MessageCode, ConfigUtil.GetItemValue("ErrorMessageTitle"));
}
serviceDelegate.MessageList.Clear();
}
}
3.伺服器代碼
MaterialService中的getDataFromXSJL方法：
public List getDataFromXSJL(String mdbh) throws Exception {
List<?> resultList = dao.selectDataFromKCDL(mdbh);
if (resultList == null || resultList.isEmpty()) {
messages.add(new ServiceMessage(CommonConst.RESULTNULL));
return null;
} else {
return resultList;
}
}
@Override
public List<?> selectDataFromKCDL(String mdbh) throws SysException {
StringBuffer sb = new StringBuffer();
List<Object> argsList = new ArrayList<Object>();
sb.append("select ");
sb.append(" WL_WLBH,WL_WLMC,WL_3LMC, WL_JLDW,sum(DXFJL_SL) AS SL");
sb.append(" from ");
sb.append(" T_JCZL_WL left join T_KWGL_DXFJL on ");
sb.append(" WL_WLBH=DXFJL_CPBH AND substr(DXFJL_XFLSH,0,?)=?");
sb.append(" where ");
sb.append(" WL_2lMC=? ");
sb.append(" group by WL_WLBH,WL_WLMC,WL_3LMC, WL_JLDW ");
// sb.append(" WL_WLMC ");
argsList.add(mdbh.length());
argsList.add(mdbh);
argsList.add("外賣");
AppLog.logSystemInfo(WlDao.class, "selectDataBy1LMC", sb.toString()
.replace('\'', '"'));
List<?> list = (List<?>) sqlRunner
.executeQuery(sb.toString(),argsList);
return WsCommon.listConvert(list, sb.toString());
}
2.3 插入和删除
操作和2.2類似.
2.4 儲存
分析：聲明configPic.txt配置檔案和圖檔的存放位置，建立檔案流和位元組流，将2.2中插入的菜品所對應的圖檔的絕對路徑存入txt檔案中，然後将txt檔案中儲存的資訊在觸屏顯示中讀取。
private void saveBtn_Click(object sender, EventArgs e)
{
string filePath = Application.StartupPath + "/Pic/used/configPic.txt";
string imagePath = Application.StartupPath + "/Pic/";
if (dataGridView1.Rows.Count < 1)
return;
imageListView1.Items.Clear();
FileStream fs = new FileStream(filePath, FileMode.Create);
StreamWriter sw = new StreamWriter(fs);
foreach (DataGridViewRow row in dataGridView1.Rows)
{
sw.WriteLine(imagePath+row.Cells["WL_WLBH"].Value.ToString() + ".jpg");
}
sw.Flush();//保護硬碟
//關閉流
sw.Close();
fs.Close();
this.toolStripStatusLabel.Text = "儲存成功！";
String[] fileLines = System.IO.File.ReadAllLines(filePath);
imageListView1.Items.AddRange(fileLines);//觸屏顯示
}
三 觸屏顯示
分析：1.顯示txt中的圖檔資訊2.增加輕按兩下事件，即輕按兩下圖檔可以檢視其細節資訊，并進入對應的窗體3.在商品細節窗體中可以把其“儲存”進購物車，并傳回。4.本界面顯示庫存餘量，若<=0，點選傳回後将自動将圖檔置換為售罄（通過字元串替換，修改config.txt檔案中的内容）
3.1 按鈕控制滾動條
//導入dll用來控制滑鼠上下移動
[DllImport("user32.dll")]
static extern void mouse_event(int flags, int dX, int dY, int buttons, int extraInfo);
const int MOUSEEVENTF_WHEEL = 0x800;
private void btnDown_Click(object sender, EventArgs e)
{
this.imageListView1.Focus();
mouse_event(MOUSEEVENTF_WHEEL, 0, 0, -300, 0);
}
private void btnUp_Click(object sender, EventArgs e)
{
this.imageListView1.Focus();
mouse_event(MOUSEEVENTF_WHEEL, 0, 0, 300, 0);
}
3.2 “傳回”按鈕事件
private void rtn_Click(object sender, EventArgs e)
{
if (this.kc.Text == "0") {//判斷目前的庫存量
string filePath = Application.StartupPath + "/Pic/used/configPic.txt";//配置文本檔案
string imagePath = Application.StartupPath + "/Pic/Out/" + _picId + "out.jpg";//Out檔案夾存儲售罄圖檔
string imagePathUsed = Application.StartupPath + "/Pic/used/" + _picId + ".jpg";//目前顯示的圖檔存儲的檔案夾
string line;
//通過位元組流操作檔案
StreamReader sr1 = new StreamReader(filePath);
string s = sr1.ReadToEnd();
sr1.Close();
StreamReader sr = new StreamReader(filePath);
while ((line = sr.ReadLine()) != null)
{
if (line.Equals(imagePathUsed)) {
sr.Close();
StreamWriter sw = new StreamWriter(filePath);
sw.WriteLine(s.Replace(imagePathUsed, imagePath).Trim());
sw.Flush();
sw.Close();
break;
}
}
}
base.MoveToNextForm(typeof(ShowBoxMain));
this.Close();
}
四 觸屏銷售
4.1 子產品展示：
分析：本子產品設計的内容較多，主要包括1.讀卡2.結算3.列印發票
4.2 讀卡
分析：關鍵點：1. CardOperation和CardDbOperation讀取卡号和卡内資料（具體讀卡操作略過，如有需要可以私信部落客）2.通過方法getDataByGWC(ickh);擷取卡内的購物車資料3.綁定資料源到dgv，注意将dgv中列的NAME屬性和DataPropertyName屬性一一對應，否則綁定失敗。
private void readBtn_Click(object sender, EventArgs e)
{
//點餐前檢查是否有IC卡放置好
DataBean dataTable1 = null;
CardOperation co = new CardOperation();
CardDbOperation codb = new CardDbOperation();
string ickh = co.getICKH();
this.ickh_txb.Text = ickh;
if (ickh.Length < 2)
{
MessageBox.Show("請放好消費卡！");
return;
}
dataTable1 = codb.getICCard(ickh);
this.knye_txb.Text = dataTable1.GetValue("IC_CZYE").ToString();
///讀卡之後，在購物車籃顯示商品
///1.讀取資料庫getAllData傳回map<key,value>
///2.将map顯示到dgv上
getDataByGWC(ickh);
this.dinnerDetailDgv.DataSource = ServiceDelegate.ListToDataTable(resultList);
int i = 0;
foreach (DataGridViewRow row in dinnerDetailDgv.Rows)
{
DataGridViewRow dgr = dinnerDetailDgv.Rows[i];
dgr.Cells["IC_ICKH"].Value = dinnerDetailDgv.Rows[i].Cells["IC_ICKH"].Value.ToString().Trim();
i++;
}
RefreshTotal();
}
//擷取門店訂單
private void getDataByGWC(string ickh)
{
ServiceDelegate serviceDelegate = ServiceDelegateFactory.Instance();
try
{
resultList = (ArrayList)serviceDelegate.CommonInvoke("CardService", "GetCaseByICKH", ickh);
}
catch (Exception ex)
{
return;
}
if (resultList == null)
{
ServiceMessageBean popMessage = (ServiceMessageBean)serviceDelegate.MessageList[0];
if (popMessage.Parameters != null)
{
PopMessage.Error(popMessage.MessageCode, ConfigUtil.GetItemValue("ErrorMessageTitle"), popMessage.Parameters);
}
else
{
PopMessage.Error(popMessage.MessageCode, ConfigUtil.GetItemValue("ErrorMessageTitle"));
}
serviceDelegate.MessageList.Clear();
}
}
4.3 結算
///1.擷取dgv上面的金額總數 ///2.操作卡内餘額 ///3.删除該IC卡的GWC資料 ///4.列印發票，擷取cgv上的資料

MessageBox.Show("歡迎光臨，您此次消費共計" + xfje + "元，卡内餘額為" + knye_new + "元，已結算成功！");
伺服器端cardService的cardConsume方法：
// 業務 ： 消費
public void cardConsume(DataBean cardData, DataBean mxfjlData,
ArrayList<DataBean> xfjlDetailList) {
ICardDaoIF icDao = new ICardDao();
MxfjlDaoIF dao = new MxfjlDao();

int kehu = 0;
try {
if (cardData != null) {
ic = icDao.updateICardData(cardData);
if (ic != 1) {
messages.add(new ServiceMessage(CommonConst.UPDATEFAIL));
return;
}
}
if (mxfjlData != null) {

4.4 列印發票
分析：在結算之後，自動執行列印發票程式。主要是格式的編排，建立LPTControls對象，傳入待列印字元串，操作發票機
//********列印發票***********
double spsl = 0;
LPTControls lpt = new LPTControls();
//string mycommanglines = System.IO.File.ReadAllText("./print.txt");//print.txt裡寫了條碼機的指令
