概述:利用Aspose.Words 完美生成word试卷(附示例代码)
# 慧都年终大促·界面/图表报表/文档/IDE等千款热门软控件火热促销中 >>
最近做了一个在线组卷的项目。主要功能实现word排版、预览,生成试卷。刚开始涉及到word操作一心想到的就是 office COM组件来操作word 。大概两周时间就写好整个系统的代码。然后就开始反复测试,本地感觉良好,能够顺利生成一份word试卷,并且性能还行。于是迫不及待的发布到了服务器。
下面说说发布遇到的一些情况,首先一个就是遇到索 COM 类工厂中 CLSID 为 {000209FF-0000-0000-C000-000000000046} 的组件失败,原因是出现以下错误: 8000401a 因为配置标识不正确,系统无法开始服务器进程。请检查用户名和密码。 (异常来自 HRESULT:0x8000401A)。
首先这中问题全都是权限所导致,解决的办法只要配置权限就可以了。不光对excel和word有用,对所有的office产品都有效果。
进入正题,首先,在运行中输入dcomcnfg打开组件服务管理器->组件服务->我的电脑->DCOM->找到对应的Microsoft excel applicotion/Microsoft word 97-2003文档,然后右键属性激活启动权限都给足够了就ok了。 --------没问题这个问题解决了。
下面再说说第二个情况》性能问题:由于我们该系统是我们网站下一个子系统。所以有一定的用户基础。该系统一上线就有大量的用户访问。刚开始一天组卷四五百份,慢慢的组卷量越来越大,这是系统就开始出问题了。首先一个就是在进程里面出现了很多 winWord.exe进程。不能结束掉。虽然系统代码里面Quit进程,并且对资源也进行了回收,但是问题始终得不到解决。大量winword.exe进程的后果就是服务器变慢了。应为该组件办本身就特别耗内存。
没办法问题要解决呀。最后的无赖之举就是KIll 写了一个定时服务,定时Kill掉没有运行的winword进程。这样做治标不治本的。、
这里要说一下微软Office是主要针对普通用户开发的桌面办公应用软件,它具有丰富的UI(用户界面)元素,是一套纯粹的本地运行软件或者说是客户端软件。Word自动化接口主要是为了方便窗口应用程序调用而设计的。例如Delphi、VB、C# Winform等开发的本地应用程序。虽然可以强制Visible为false,Word可以运行在服务器端代码里,但毕竟还是会带来许多棘手问题。
1. ASP.NET是基于B/S架构的。B/S架构下用户访问都是并发的,也就是说经常会出现同时N个用户对一个服务器页面发出请求。在这种情况下Word自动化调用会时常出现死进程。
2. 由于隐藏界面运行,一些涉及界面的可以在窗口程序里成功调用的接口,在服务器端调用就会失败,甚至崩溃,这种情况也会经常导致死进程。
3. 由于Word是复杂的桌面程序,并不符合一般Web服务程序简洁高效的标准,所以在服务器端运行时速度慢,并且还会消耗大量资源(CPU、内存),尤其不能支持大量用户同时访问,资源会很快耗尽。
4. 绝大部分开发者对COM技术比较陌生,在编程调用Word接口时经常存在一些代码错误,而又很难检查到问题所在,这又是导致死进程的经常因素。Word死进程不仅会消耗服务器资源,还经常会导致服务器页面不能创建新的Word自动化对象而无法继续工作。有网友提出死进程解决方法:编程Kill掉Word死进程,这样是治标不治本的做法,Word死进程是不在了,可是Word非正常关闭会导致很多资源无法及时释放。这样的Web服务器能持续工作多久恐怕就很难说了。
为了解决这些问题,笔者经过全面研究比较,发现aspose.words完全消除了以上问题,推荐给大家分享。
