Question

我有一段创建问题的代码。我用于合并的以下代码如下：

<cfset inFiles = [#convertArray#]>
<cfset outFile = "c:\merged_1.pdf">
<cfscript>
try {
    outStream = createObject("java", "java.io.FileOutputStream").init( outFile );
    copy = createObject("java", "com.lowagie.text.pdf.PdfCopyFields").init(outStream);
    PdfReader = createObject("java", "com.lowagie.text.pdf.PdfReader");
    for (inFile in inFiles) {
        reader = PdfReader.init( inFile );
        copy.addDocument(reader);
        //writedump(inFile);
    }
    WriteOutput("Finished!");
}
catch (java.language.Exception de) {
    writedump(de);
}
if (IsDefined("copy")) {
    copy.close();
}
if (IsDefined("outputStream")) {
    outputStream.close();
}
</cfscript>

convertArray是像这样的文件列表

"C:\ColdFusion10\cfusion\wwwroot\_pdf\YEF5.pdf","C:\ColdFusion10\cfusion\wwwroot\_pdf\WEX9.pdf","C:\ColdFusion10\cfusion\wwwroot\_pdf\1WFX8.pdf","C:\ColdFusion10\cfusion\wwwroot\_pdf\WFY6.pdf","C:\ColdFusion10\cfusion\wwwroot\_pdf\1WFZ3.pdf"

如果我传递硬编码值，它会起作用，但如果我将其作为convertArray发送，则会抛出以下错误

31 :        copy.addDocument(reader);

如果查看堆栈跟踪消息，则表明提供的路径字符串无效：

java.io.IOException的： “C：/ColdFusion10/cfusion/wwwroot/_pdf/YEF5.pdf”， “C：/ColdFusion10/cfusion/wwwroot/_pdf/1WEX9.pdf”， “C：/ColdFusion10/cfusion/wwwroot/_pdf/1WFX8.pdf” “C：/ColdFusion10/cfusion/wwwroot/_pdf/1WFY6.pdf”， “C：/ColdFusion10/cfusion/wwwroot/_pdf/1WFZ3.pdf” 未找到文件或资源

从错误消息中的值开始，当传入单个路径时，您将传入包含多个文件路径的字符串。如果convertArray变量包含路径列表，请使用ListToArray函数将其转换为数组。只要每个元素包含单个（有效）文件路径，代码就可以正常工作。

如果您仍然收到“找不到文件或资源”错误，则表示路径无效或无法访问。添加一些调试，以便您可以查看实际的文件路径并验证它们是否是有效文件：

<cfscript>
    // convert list of files into array
    convertArray = "c:/path/FirstFile.pdf,c:/otherpath/SecondFile.pdf";
    inFiles = listToArray(convertArray);
    outFile = "c:\temp\merged_1.pdf";

    try {
        // ... 
        for (inFile in inFiles) {

            // Verify current value is valid file path
            writeOutput("<br>DEBUG: Current Path: "& inFile );
            writeOutput(" FileExists("& FileExists(inFile) &")");

            // ... initialize reader and copy file 
        }
    }
    // ...etcetera
</cfscript>

使用java方法合并pdf并获取错误
