關(guān)聯(lián)產(chǎn)品：Aspose.Words
最近做了一個在線組卷的項目。主要功能實現(xiàn)word排版、預(yù)覽，生成試卷。剛開始涉及到word操作一心想到的就是 office COM組件來操作word 。大概兩周時間就寫好整個系統(tǒng)的代碼。然后就開始反復(fù)測試，本地感覺良好，能夠順利生成一份word試卷，并且性能還行。于是迫不及待的發(fā)布到了服務(wù)器。
下面說說發(fā)布遇到的一些情況，首先一個就是遇到索 COM 類工廠中 CLSID 為 {000209FF-0000-0000-C000-000000000046} 的組件失敗，原因是出現(xiàn)以下錯誤: 8000401a 因為配置標(biāo)識不正確，系統(tǒng)無法開始服務(wù)器進(jìn)程。請檢查用戶名和密碼。 (異常來自 HRESULT:0x8000401A)。
首先這中問題全都是權(quán)限所導(dǎo)致，解決的辦法只要配置權(quán)限就可以了。不光對excel和word有用，對所有的office產(chǎn)品都有效果。
進(jìn)入正題，首先，在運行中輸入dcomcnfg打開組件服務(wù)管理器->組件服務(wù)->我的電腦->DCOM->找到對應(yīng)的Microsoft excel applicotion/Microsoft word 97-2003文檔，然后右鍵屬性激活啟動權(quán)限都給足夠了就ok了。 --------沒問題這個問題解決了。
下面再說說第二個情況》性能問題：由于我們該系統(tǒng)是我們網(wǎng)站下一個子系統(tǒng)。所以有一定的用戶基礎(chǔ)。該系統(tǒng)一上線就有大量的用戶訪問。剛開始一天組卷四五百份，慢慢的組卷量越來越大，這是系統(tǒng)就開始出問題了。首先一個就是在進(jìn)程里面出現(xiàn)了很多 winWord.exe進(jìn)程。不能結(jié)束掉。雖然系統(tǒng)代碼里面Quit進(jìn)程，并且對資源也進(jìn)行了回收，但是問題始終得不到解決。大量winword.exe進(jìn)程的后果就是服務(wù)器變慢了。應(yīng)為該組件辦本身就特別耗內(nèi)存。
沒辦法問題要解決呀。最后的無賴之舉就是KIll 寫了一個定時服務(wù)，定時Kill掉沒有運行的winword進(jìn)程。這樣做治標(biāo)不治本的。、
這里要說一下微軟Office是主要針對普通用戶開發(fā)的桌面辦公應(yīng)用軟件，它具有豐富的UI（用戶界面）元素，是一套純粹的本地運行軟件或者說是客戶端軟件。Word自動化接口主要是為了方便窗口應(yīng)用程序調(diào)用而設(shè)計的。例如Delphi、VB、C# Winform等開發(fā)的本地應(yīng)用程序。雖然可以強(qiáng)制Visible為false，Word可以運行在服務(wù)器端代碼里，但畢竟還是會帶來許多棘手問題。
1. ASP.NET是基于B/S架構(gòu)的。B/S架構(gòu)下用戶訪問都是并發(fā)的，也就是說經(jīng)常會出現(xiàn)同時N個用戶對一個服務(wù)器頁面發(fā)出請求。在這種情況下Word自動化調(diào)用會時常出現(xiàn)死進(jìn)程。
2. 由于隱藏界面運行，一些涉及界面的可以在窗口程序里成功調(diào)用的接口，在服務(wù)器端調(diào)用就會失敗，甚至崩潰，這種情況也會經(jīng)常導(dǎo)致死進(jìn)程。
3. 由于Word是復(fù)雜的桌面程序，并不符合一般Web服務(wù)程序簡潔高效的標(biāo)準(zhǔn)，所以在服務(wù)器端運行時速度慢，并且還會消耗大量資源(CPU、內(nèi)存)，尤其不能支持大量用戶同時訪問，資源會很快耗盡。
4. 絕大部分開發(fā)者對COM技術(shù)比較陌生，在編程調(diào)用Word接口時經(jīng)常存在一些代碼錯誤，而又很難檢查到問題所在，這又是導(dǎo)致死進(jìn)程的經(jīng)常因素。Word死進(jìn)程不僅會消耗服務(wù)器資源，還經(jīng)常會導(dǎo)致服務(wù)器頁面不能創(chuàng)建新的Word自動化對象而無法繼續(xù)工作。有網(wǎng)友提出死進(jìn)程解決方法：編程Kill掉Word死進(jìn)程，這樣是治標(biāo)不治本的做法，Word死進(jìn)程是不在了，可是Word非正常關(guān)閉會導(dǎo)致很多資源無法及時釋放。這樣的Web服務(wù)器能持續(xù)工作多久恐怕就很難說了。
為了解決這些問題，筆者經(jīng)過全面研究比較，發(fā)現(xiàn)aspose.words完全消除了以上問題，推薦給大家分享。
