??? 在用java作項目程序開發過程中，遇到財務制度要求在作社保基金支付時，套打《專用付款款憑證》，金額項除阿拉伯數字外，還要求將人民幣（大寫）打印出來；另有許多參保人員，居民身份證的位數由15位更換成18位，若此類人員進行新參保登記時，不進行校驗檢查，將會造成同一參保人員，以不同的居民身份證號在業務系統中進行重復登記。故需提供將15位身份證轉換成18位，并檢驗此值與核心數據庫是否有相同值，有則提示此人員已參保。另提供對18位身份證的校驗功能（注：按已公布的國標算法）。
模塊描述：
??? （1）人民幣在大寫功能轉換，見doubleToChinese模塊，實現的方法為將數值及位數分別取出后，按對應的值將其轉換成字串即可。如100，則大寫金額為“壹百整“；對負金額則加負字，例-100.01，大寫金額為“負壹百零壹分整”。
??? （2）身份證由15位轉18位，可見fixPersonIDCode模塊。附：提交判斷是否為有效的18位身份證號isIdentityId模塊，方法為判斷年份為19開頭的18位身份證號，將其轉化為15位后，按國標進行修補，若經轉換的值同輸入的18位值相同，則說明身份證編號是有效的，否則身份證號可能有誤；考慮到2000年以后出生的人的身份證編號，可能到2016年以后才能申請到，到時此系統能否還在使用很難說，故暫未提供對其身份證號碼的判斷功能。但在此也提供解決的辦法，可以先判斷18位身份證中的年份，對以20開頭的年份，進行轉換時修補程序中改為加20既可。
??? 目前以上功能模塊在社保核心業務系統應用正常。
??? 本例用jbuilder7編譯通過。說明：以下代碼中所加注的說明，說明功能模塊的作用。在具體應用中借鑒或拷貝此代碼到實際程序中即可使用。
