篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了软件工程短学期实践第三次随笔相关的知识，希望对你有一定的参考价值。

软件工程短学期实践即将接近尾声，我们的软件工程项目也已趋于完成。

软件工程短学期实践项目：

技术分享

这是一个简单的客户信息管理维护软件，它能把客户编号、客户姓名、客户电话和客户性别保存在数据库之中，我们可以在数据库中查询保存的客户信息，还可以随时修改以及删除客户信息。

随后，我们在老师的指导下，开始自己修改设计软件，我做的是库存管理项目，代码如下：

package com.crm.action;

import java.util.Map;

import com.crm.bean.Item;
import com.crm.service.ItemService;

        public Item getItem() {
            return item;
        }
        public void setItem(Item item) {
            this.item = item;
        }
        public ItemService getFindCdtService() {
            return findCdtService;
        }
        public void setFindCdtService(ItemService findCdtService) {
            this.findCdtService = findCdtService;
        }

            map.put("list", this.findCdtService.findItemByCondition(item));
            return SUCCESS;
