Java調(diào)用外接設(shè)備詳解（制卡機(jī)）

這篇文章主要為大家詳細(xì)介紹了Java調(diào)用外接設(shè)備的相關(guān)資料，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

最近在開發(fā)的系統(tǒng)中，有一個(gè)接入外接設(shè)備制卡機(jī)更換，之前用的制卡機(jī)要重新采購(gòu)，所以導(dǎo)致之前的調(diào)用接口方法無(wú)效，要用新的設(shè)備接口來(lái)進(jìn)行調(diào)用?？墒沁@個(gè)設(shè)備是外國(guó)進(jìn)口過來(lái)的，資料很少。想要百度的話，網(wǎng)上資料都沒有，中間經(jīng)過了幾天的摸索，最終還是弄了出來(lái)，所以把詳細(xì)的分析及解決方法記錄下來(lái)。

這個(gè)制卡機(jī)是打印磁卡/智能卡的，像我們常用的銀行卡、飯卡、購(gòu)物卡都可以用這個(gè)機(jī)器來(lái)進(jìn)行設(shè)計(jì)并制卡，并最終發(fā)放給消費(fèi)者使用。簡(jiǎn)要說下解決的思路吧，最開始拿到這個(gè)機(jī)器的時(shí)候，我是一頭的霧水，也不知道從何下手，我當(dāng)時(shí)最最簡(jiǎn)單的想法就是先把這個(gè)機(jī)器怎么使用，怎么操作，什么用途了解清楚，然后再談接口代碼啥的。但是找了半天，網(wǎng)上的資料也很少，也不知道怎么使用，最后看到機(jī)器上有一個(gè)二維碼幫助的，掃了下，進(jìn)入到了它們的官網(wǎng)，找到了相應(yīng)的機(jī)器型號(hào)，然后的話看到了相應(yīng)的使用說明和相應(yīng)的視頻教程，了解了一番，這才知道了產(chǎn)品正確的使用方法，所以拿到一個(gè)新玩意，想要快速了解它，最好的還是先去看他的說明書和官方教程。

知道了相應(yīng)的使用方法，下面的操作也就很簡(jiǎn)單了。其實(shí)具體的原理方法也就是先使用軟件設(shè)計(jì)出兩張BMP的圖片，一面是磁卡/智能卡的正面，一般的話都是張?jiān)O(shè)計(jì)的好看的圖片，另一張的話就是磁卡/智能卡的反面，然后圖片的給相應(yīng)的代碼解析，讀取，把信息寫入到卡的磁條上，最后調(diào)用機(jī)器進(jìn)行打印，用其中機(jī)器的墨紙寫入到空白的卡片上就可以了。

但是一般人工都是機(jī)器自帶的軟件提前設(shè)計(jì)好圖片，如果換做用代碼驅(qū)動(dòng)機(jī)器的話，那就要用代碼要生成圖片了。當(dāng)然了，在JAVA中有相應(yīng)的類來(lái)生成BMP格式的圖片，然后調(diào)用相應(yīng)的代碼就可以了。

上面的代碼是JSP調(diào)用的后臺(tái)請(qǐng)求邏輯代碼，在JSP頁(yè)面可以用AJAX請(qǐng)求，然后執(zhí)行相應(yīng)的代碼塊進(jìn)行相應(yīng)的執(zhí)行代碼進(jìn)行調(diào)用制卡機(jī)外接設(shè)備。值得一提的是，由于在調(diào)用相應(yīng)的外接設(shè)備的時(shí)候，會(huì)調(diào)用到相應(yīng)的.dll擴(kuò)展文件，這個(gè)在使用TOMCAT/WebSpare的時(shí)候，需要把.dll文件放到bin目錄下，不然的話可能會(huì)調(diào)用失敗。這一點(diǎn)要特別注意，因?yàn)樵赟DK中，java程序的話可能是執(zhí)行通過的，但是java web項(xiàng)目則必須要注意到這一點(diǎn)。
