Web應用開發(fā)工程師案例手冊

1、Web應用開發(fā)工程師案例手冊-財務報銷管理系統(tǒng)一、項目需求分析1、項目背景描述某學院的財務部門，現(xiàn)在感覺到本院的財務支出管理有點混亂， 對于個別業(yè)務部門存在任意開支的現(xiàn)象， 所以希望通過網上統(tǒng)一登記 報銷細目的形式，財務主管和院領導可以隨時掌握學院的經費支出情 況。學院的財務形式描述如下：每年學院的國家撥款及各類收入都 按照各個業(yè)務部門的預算，劃成分類的賬號，所有的支出都按照其所 發(fā)生的業(yè)務性質所屬賬號進行報銷。各個賬號有相應的負責人和出 納，有的負責人會有多個賬號的支配權限， 有的出納可以操作多個賬 號，只要業(yè)務相關即可，這些都是由財務主管來分配。用戶已經提供原始表格，一期任務把該表格實現(xiàn)網

2、上填報即可。 財務主管可以看到全院所有的報銷信息，財務助理只能看到自己錄入 的信息。所有的記錄應可以導出Excel表格。2、需求概要分析(1)、用戶和角色權限部分：財務主管維護系統(tǒng)用戶，并為用戶 指定角色，用戶的初始化密碼和證件號相同，各用戶自己登陸后可修 改密碼。角色分為三類： 、出納：可以對自己被授權的賬號進行報銷記錄的維護；、賬號負責人：可以對自己被授權的賬號進行查詢，不能做新增、修改、刪除等操作；清華大學計算機與信息管理中心第2頁、財務主管：可以查詢、維護全院所有賬號的報銷記錄；(2)、報銷記錄維護：填寫報銷記錄時，需要記錄摘要、費用類型、經辦人、所屬賬號、 記錄人、記錄時間、處理方式

3、等信息。參考用戶提供的原始表格。為規(guī)范填寫，費用記錄、處理方式都做標準化處理，財務主管維 護代碼表后，出納錄入時選擇錄入。為避免賬號填寫錯誤，出納錄入時，賬號信息也是選擇方式錄入， 每個出納只能列出自己被授權的賬號。(3)、報銷記錄查詢根據(jù)賬號、費用類型、金額范圍 等字段進行查詢。出納和賬號 負責人只能查詢到自己被授權的賬號的報銷記錄。 財務主管可以看到 所有賬號的報銷記錄。查詢結果最下方，需要對金額字段做匯總。查詢結果應該能導出Excel3、開發(fā)技術參數(shù)數(shù)據(jù)庫采用Oracle;系統(tǒng)架構采用 Struts + Spring + Hibernate ;涉及開發(fā)環(huán)境和工具：JDK1.5 Eclip
