??? 很長時間沒有寫B(tài)LOG了，先啰嗦幾句。
??? 我已經(jīng)從一家不知名的小公司又一次回到了大公司里了，這是我7年工作來又一次回歸大公司。當然了小公司有小公司的心胸狹窄和陰險，大公司有嚴格的管理制度和進升方式，這都不能夠相提并論。所以建議有能力的朋友在大公司里做事，能夠讓自己用正確的方式做正確的事。
?-----------------------天行鍵，君子以自強不息!
??? 話入正題。
??? 在大家的編碼過程當中，有沒有遇到過這么一種情況，很多零亂的狀態(tài)、分類和其它常用選項常常是定義死了。但是沒有一個完整的東東來約束他，在每個模塊當中使用相關(guān)的信息時，往往重新COPY一次，或者COPY過來修改一次。如果多人協(xié)作的話，務(wù)必會讓代碼變的零亂、不好管理等。
??? 本次主要是把一些靜態(tài)的分類、狀態(tài)或者其它常用選項使用二維數(shù)組管理起來。如果你是一個使用JSTL或者STRUTS做前臺表現(xiàn)的話，你就更應(yīng)該好好關(guān)注了。
??? 以下以一個審核的狀態(tài)做示例，使用代碼實現(xiàn)(光說不練是假功夫).

具體使用方法
/*Antbee?@家軍
*/
Config?n?=?new?Config();
List?View_Stutas?=?n.Stutas;????????request.setAttribute("View_Stutas",?View_Stutas);
頁面當中示例：
<c:forEach?items="${View_Stutas}"?var="View_Stutas">
??????????????<option?value="<c:out?value="${View_Stutas.typeSeri?}"?/>"><c:out?value="${View_Stutas.typeEnName}"/></option>
???????????</c:forEach>
可以看出，在實體類里一共有三個方法,其它有兩個名字， 一個是中文名字，一個是英文名字，你可以在頁面當中截取本地語言并顯示其中一個語言就行。
