??? 在用java作項(xiàng)目程序開(kāi)發(fā)過(guò)程中,，遇到財(cái)務(wù)制度要求在作社?；鹬Ц稌r(shí),，套打《專用付款款憑證》,，金額項(xiàng)除阿拉伯?dāng)?shù)字外,，還要求將人民幣（大寫）打印出來(lái),；另有許多參保人員,，居民身份證的位數(shù)由15位更換成18位,，若此類人員進(jìn)行新參保登記時(shí),，不進(jìn)行校驗(yàn)檢查,，將會(huì)造成同一參保人員，以不同的居民身份證號(hào)在業(yè)務(wù)系統(tǒng)中進(jìn)行重復(fù)登記,。故需提供將15位身份證轉(zhuǎn)換成18位,，并檢驗(yàn)此值與核心數(shù)據(jù)庫(kù)是否有相同值，有則提示此人員已參保,。另提供對(duì)18位身份證的校驗(yàn)功能（注：按已公布的國(guó)標(biāo)算法）,。
模塊描述：
??? （1）人民幣在大寫功能轉(zhuǎn)換，見(jiàn)doubleToChinese模塊,，實(shí)現(xiàn)的方法為將數(shù)值及位數(shù)分別取出后,，按對(duì)應(yīng)的值將其轉(zhuǎn)換成字串即可。如100,，則大寫金額為“壹百整“,；對(duì)負(fù)金額則加負(fù)字，例-100.01,，大寫金額為“負(fù)壹百零壹分整”,。
??? （2）身份證由15位轉(zhuǎn)18位，可見(jiàn)fixPersonIDCode模塊,。附：提交判斷是否為有效的18位身份證號(hào)isIdentityId模塊,，方法為判斷年份為19開(kāi)頭的18位身份證號(hào)，將其轉(zhuǎn)化為15位后,，按國(guó)標(biāo)進(jìn)行修補(bǔ),，若經(jīng)轉(zhuǎn)換的值同輸入的18位值相同，則說(shuō)明身份證編號(hào)是有效的,，否則身份證號(hào)可能有誤,；考慮到2000年以后出生的人的身份證編號(hào)，可能到2016年以后才能申請(qǐng)到,，到時(shí)此系統(tǒng)能否還在使用很難說(shuō),，故暫未提供對(duì)其身份證號(hào)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(duì)以20開(kāi)頭的年份，進(jìn)行轉(zhuǎn)換時(shí)修補(bǔ)程序中改為加20既可,。
??? 目前以上功能模塊在社保核心業(yè)務(wù)系統(tǒng)應(yīng)用正常,。
??? 本例用jbuilder7編譯通過(guò)。說(shuō)明：以下代碼中所加注的說(shuō)明,，說(shuō)明功能模塊的作用。在具體應(yīng)用中借鑒或拷貝此代碼到實(shí)際程序中即可使用,。
