代码如下:
public class WordToPdf {
static final int wdFormatPDF = 17;// PDF 格式
public void wordToPDF(String sfileName, String toFileName) {
System.out.println("启动Word...");
long start = System.currentTimeMillis();
ActiveXComponent app = null;
Dispatch doc = null;
try {
app = new ActiveXComponent("Word.Application");
app.setProperty("Visible", new Variant(false));
Dispatch docs = app.getProperty("Documents").toDispatch();
// doc = Dispatch.call(docs, "Open" , sourceFile).toDispatch();
doc = Dispatch.invoke(
docs,
"Open",
Dispatch.Method,
new Object[] { sfileName, new Variant(false),
new Variant(true) }, new int[1]).toDispatch();
System.out.println("打开文档..." + sfileName);
System.out.println("转换文档到PDF..." + toFileName);
// File tofile = new File(toFileName);
// if (tofile.exists()) {
// tofile.delete();
// }
// Dispatch.call(doc, "SaveAs", destFile, 17);
Dispatch.invoke(doc, "SaveAs", Dispatch.Method, new Object[] {
toFileName, new Variant(17) }, new int[1]);
long end = System.currentTimeMillis();
System.out.println("转换完成..用时" + (end - start) + "ms.");
} catch (Exception e) {
e.printStackTrace();
System.out.println("========Error:文档转换失败" + e.getMessage());
} finally {
Dispatch.call(doc, "Close", false);
System.out.println("关闭文档");
if (app != null)
app.invoke("Quit", new Variant[] {});
}
ComThread.Release();
}
public static void main(String[] args) {
WordToPdf d = new WordToPdf();
d.wordToPDF("E:/testHtml/1.docx", "E:/abc/2.pdf");
}
}
运行环境:window64位,office2010;jacob-1.17-M2-x64.dll也放在了jre/bin目录下,自己做的测试没问题,能正常转换成功,可加到项目中来,一直报错,经排查发现:
在执行
Dispatch.invoke(doc, "SaveAs", Dispatch.Method, new Object[] {toFileName, new Variant(17) }, new int[1]);
这句之前,pdf就已经生成了,但是生成是有问题的pdf文件,当再次执行
Dispatch.invoke(doc, "SaveAs", Dispatch.Method, new Object[] {toFileName, new Variant(17) }, new int[1]);
这句话时,由于之前的文件有问题,所有word内容是写不进去的,故在此句代码执行前进行了判断:
File tofile = new File(toFileName);
if (tofile.exists()) {
tofile.delete();
}
由于自己之前不清楚将这句代码注释了,所有引起的报错。
