小学期的大作业做的是库存管理系统。在做之前，我们组员之间先进行了思路的整理：要做好一个库存管理系统，我们要有一个能满足尽量多条件的数据库，初步定为库存编号、货物名称、货物渠道。货物数量、进货时间。其次，一个吸引用户的界面也是非常重要的。

方向定好后，我们就进入了实战阶段。基于客户管理系统，我建立了一个如下图所示的工程：

接着，对库存数据的增删查改等操作进行了编码：

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;

* 调用service服务，存储库存信息

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增加动态地入库时间

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

String time = format.format(date);

stock.setStocktime(time);

this.service.saveStock(stock); //调用service服务，存入stock

return SUCCESS;

}

package com.crm.action;

import com.crm.bean.Stock;

import com.crm.service.StockService;

import com.opensymphony.xwork2.ActionSupport;

* 调用service服务，删除库存信息

public class StockDeleteAction 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 Auto-generated method stub

this.service.deleteStock(stock); //调用service服务，删除库存信息

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;

* 调用service服务，条件查找信息

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"); //通过监听器获取前端得到的信息

map.put("list",this.findCdService.findStockByCondition(stock)); //通过调用service条件查找前端的信息，并插入列表

return SUCCESS;

}

package com.crm.action;

import com.crm.bean.Stock;

import com.crm.service.StockService;

import com.opensymphony.xwork2.ActionSupport;

* 调用service服务，预览库存信息

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()); //调用service服务，通过查找id获取信息

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;

* 调用service服务，查询所有库存信息

public class StockListAction extends ActionSupport{

private StockService service;

private Stock stock;

public StockService getService() {

return service;

}

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

Map map=(Map)ActionContext.getContext().get("request"); //通过监听器获取前端得到的请求

map.put("list", this.service.findAllStock()); //通过调用service条件查找前端的信息，并插入列表

return SUCCESS;

}

package com.crm.action;

import java.io.InputStream;

import com.crm.service.StockService;

import com.opensymphony.xwork2.ActionSupport;

* 调用service服务，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;

}

然后，对网页进行了美化工作：
<%@ page language="java" contentType="text/html; charset=utf-8"

pageEncoding="utf-8"%>

<%@ taglib prefix="s" uri="/struts-tags" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

</s:iterator>

</ul>
