@override context 滿足 -m ont 編號 util wid sets

小學期的大作業做的是庫存管理系統。在做之前，我們組員之間先進行了思路的整理：要做好一個庫存管理系統，我們要有一個能滿足盡量多條件的數據庫，初步定為庫存編號、貨物名稱、貨物渠道。貨物數量、進貨時間。其次，一個吸引用戶的界面也是非常重要的。

方向定好後，我們就進入了實戰階段。基於客戶管理系統，我建立了一個如下圖所示的工程：

接著，對庫存數據的增刪查改等操作進行了編碼：

package com.crm.action;

import java.text.DateFormat;

import java.text.SimpleDateFormat;

import java.util.Date;

import com.crm.bean.Stock;

import com.crm.service.StockService;

import com.opensymphony.xwork2.ActionSupport;

/*

* 調用service服務，存儲庫存信息

*/

public class StockSaveAction extends ActionSupport{

private StockService service;

private Stock stock;

/**

* @return the service

*/

public StockService getService() {

return service;

}

/**

* @param service the service to set

*/

public void setService(StockService service) {

this.service = service;

}

/**

* @return the stock

*/

public Stock getStock() {

return stock;

}

/**

* @param stock the stock to set

*/

public void setStock(Stock stock) {

this.stock = stock;

}

@Override

public String execute() throws Exception {

// TODO Asuto-generated method stub

Date date = new Date(); //new Date增加動態地入庫時間

DateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

String time = format.format(date);

stock.setStocktime(time);

this.service.saveStock(stock); //調用service服務，存入stock

return SUCCESS;

}

}

package com.crm.action;

import com.crm.bean.Stock;

/*

}

/**

*/

public void setService(StockService service) {

this.service = service;

}

/**

*/

public Stock getStock() {

return stock;

}

/**

*/

public void setStock(Stock stock) {

this.stock = stock;

}

@Override

public String execute() throws Exception {

// TODO Auto-generated method stub

this.service.deleteStock(stock); //調用service服務，刪除庫存信息

return SUCCESS;

}

}

/*

*/

public class StockFindByCdAction extends ActionSupport{

private StockService findCdService;

private Stock stock;

public StockService getFindCdService() {

return findCdService;

}

public void setFindCdService(StockService findCdService) {

this.findCdService = findCdService;

}

public Stock getStock() {

return stock;

}

public void setStock(Stock stock) {

this.stock = stock;

}

@Override

public String execute() throws Exception {

// TODO Auto-generated method stub

Map map=(Map)ActionContext.getContext().get("request"); //通過監聽器獲取前端得到的信息

map.put("list",this.findCdService.findStockByCondition(stock)); //通過調用service條件查找前端的信息，並插入列表

return SUCCESS;

}

}

package com.crm.action;

import com.crm.bean.Stock;

import com.crm.service.StockService;

import com.opensymphony.xwork2.ActionSupport;

/*

*/

public class StockPreviewAction extends ActionSupport{

private StockService stockPreviewService;

private Stock stock;

public StockService getStockPreviewService() {

return stockPreviewService;

}

public void setStockPreviewService(StockService stockPreviewService) {

this.stockPreviewService = stockPreviewService;

}

public Stock getStock() {

return stock;

}

public void setStock(Stock stock) {

this.stock = stock;

}

@Override

public String execute() throws Exception {

// TODO Auto-generated method stub

stock=this.stockPreviewService.findCustomerById(stock.getId()); //調用service服務，通過查找id獲取信息

return SUCCESS;

}

}

package com.crm.action;

import java.util.Map;

import com.crm.bean.Stock;

import com.crm.service.StockService;

import com.opensymphony.xwork2.ActionContext;

import com.opensymphony.xwork2.ActionSupport;

/*

*/

public class StockListAction extends ActionSupport{

}

public void setStock(Stock stock) {

this.stock = stock;

}

@Override

public String execute() throws Exception {

// TODO Auto-generated method stub

Map map=(Map)ActionContext.getContext().get("request"); //通過監聽器獲取前端得到的請求

map.put("list", this.service.findAllStock()); //通過調用service條件查找前端的信息，並插入列表

return SUCCESS;

}

}

package com.crm.action;

import java.io.InputStream;

import com.crm.service.StockService;

import com.opensymphony.xwork2.ActionSupport;

/*

* 調用service服務，生成excel文件

*/

public class GenerateExcelAction extends ActionSupport {

private static final long serialVersionUID = 7213178640352795420L;

private StockService excelService;

@Override

public String execute() throws Exception {

// TODO Auto-generated method stub

return SUCCESS; //返回success

}

public StockService getExcelService() {

return excelService;

}

public InputStream getDownloadFile(){

return this.excelService.getInputStream();

}

public void setExcelService(StockService excelService) {

this.excelService = excelService;

}

public static long getSerialVersionUID() {

return serialVersionUID;

}

}

然後，對網頁進行了美化工作：
