Question

我只是想知道是否还有其他选项可以使用<cfdocument>可以利用网络套件API进行ColdFusion。

或者，如果有一个可用的Java，但它上面有一个很好的ColdFusion包装器，比使用java的所有复杂功能更容易。

Answer 1

我深入了解并使用iText。这样做我创建了一个非常强大的打印框架（用于打印表单）和报告框架（表格报告）。多年来我对它进行了很好的调整，它可以生成数十万行的PDF没问题。它可以深入4个孩子，并具有许多功能/设置。对不起这么广泛。如果你走这条路，我可以提供具体的帮助。

我在onApplicationStart中使用JavaLoader（http://javaloader.riaforge.org/）来加载iText（以及我在我的应用中需要的其他jar）......

<!--- note, this is actually a harcoded UUID value --->
<cfset MyUniqueKeyForJavaLoader = "1111-2222-3333444455556666">
<!--- if we have not already created the javaLoader --->
<cfif not structKeyExists(server, MyUniqueKeyForJavaLoader)>
    <!--- construct an array containing the full path to the jars you wish to load --->
    <cfset pathArray = arrayNew(1)>
    <cfset arrayAppend(pathArray, expandpath('jars/iText-2.1.3.jar'))>
    <!---<cfset arrayAppend(pathArray, expandpath('jars/iText-5.0.6.jar'))>--->
    <cfset arrayAppend(pathArray, expandpath('jars/IDADataMatrix.jar'))>
    <cfset arrayAppend(pathArray, expandpath('jars/LinearBarCode.jar'))>
    <cfset arrayAppend(pathArray, expandpath('jars/barcodeencoder.jar'))>
    <cfset arrayAppend(pathArray, expandpath('jars/sshcommandexecutor.jar'))>
    <!--- <cfset arrayAppend(pathArray, expandpath('jars/jsch-0.1.40.jar'))> --->
    <cflock scope="server" type="exclusive" timeout="10">
        <!--- verify again the javaloader was not already created --->
        <cfif not StructKeyExists(server, MyUniqueKeyForJavaLoader)>
            <cfset server[MyUniqueKeyForJavaLoader] = createObject("component", "javaloader.JavaLoader").init(pathArray)>
        </cfif>
    </cflock>
</cfif>

然后，在报告框架中，您将开始初始化所有内容。（这只是一个小片段，除此之外还有很多东西，但是如果你决定，它应该足以让你开始愚弄。）

<cfscript>
    pathAndFile      = request.reportDir.fpath&request.reportDir.pdfFile;
    session.reports[libRptId].pathAndFile = pathAndFile;
    loader           = server['1111-2222-3333444455556666']; //Our iText version which currently is 2.1.3 (yes, we need to update soon)
    document         = loader.create("com.lowagie.text.Document");
    PdfWriter        = loader.create("com.lowagie.text.pdf.PdfWriter");
    FileOutputStream = createObject("java", "java.io.FileOutputStream");
    myFile           = CreateObject("java","java.io.File").init(pathAndFile); //Only used for getting the file size to display on screen in real-time as the pdf is being generated
    Color            = createObject("java", "java.awt.Color");
    element          = loader.create("com.lowagie.text.Element");
    Chunk            = loader.create("com.lowagie.text.Chunk");
    PageSize         = loader.create("com.lowagie.text.PageSize");
    HeaderFooter     = loader.create("com.lowagie.text.HeaderFooter");
    Rectangle        = loader.create("com.lowagie.text.Rectangle");
    Paragraph        = loader.create("com.lowagie.text.Paragraph");
    PdfPCell         = loader.create("com.lowagie.text.pdf.PdfPCell");
    PdfPTable        = loader.create("com.lowagie.text.pdf.PdfPTable");
    Phrase           = loader.create("com.lowagie.text.Phrase");
    Font             = loader.create("com.lowagie.text.Font");
    FontFactory      = loader.create("com.lowagie.text.FontFactory");
</cfscript>

<!--- Define our different fonts --->
<cfset fontTitle       = FontFactory.getFont("Arial", 10,                 Font.BOLD,       Color.BLACK)>

<cfset fontData        = FontFactory.getFont("Arial", rpt.fontsize,       Font.NORMAL,     Color.BLACK)>

    </cfif>

Answer 2

我们使用一个名为wkhtmltopdf的小应用程序，它允许您从任何HTML页面创建PDF。它适用于命令行，因此您可以使用<cfexecute>来运行它。我还使用以下代码确保PDF在输出之前完全形成：

<cfset truePDF = "false">
<cfloop condition="NOT truePDF">
    <cfif fileExists("#pathname##filename#")>
        <cffile action="read" file="#pathname##filename#" variable="pdfContent">
        <cfif findNoCase('%%EOF',right(pdfContent,1024)) GT 0>
            <cfset truePDF = "true">
        </cfif>
    </cfif>
</cfloop>
<cfoutput>#pdfContent#</cfoutput>
