我已经使用documents4j将.docx文件转换为.pdf，但是即使日志显示转换成功，pdf也没有显示。

26-Jun-2020 21:45:38.163 INFO [http-nio-80-exec-423] com.documents4j.conversion.msoffice.MicrosoftWordBridge.startUp From-Microsoft-Word-Converter was started successfully

26-Jun-2020 21:45:38.440 INFO [http-nio-80-exec-423] com.documents4j.job.LocalConverter.shutDown The documents4j local converter has shut down successfully

调试还显示以下内容：

LocalConversion{pending=false, cancelled=false, done=true, priority=Priority{value=500, creationTime=1593207938174}, file-system-target=C:\Program Files\Apache Software Foundation\Tomcat 9.0\webapps\stock\batimp\RECTO_BAT20200045.pdf}

为什么pdf没有显示在目录中？

程序片段

File wordFile = new File(FILE_NAMEX), target = new File(outputFile1);
IConverter converter = LocalConverter.builder().baseFolder(new File(path+"batimp"))
.workerPool(20, 25, 2, TimeUnit.SECONDS)
.processTimeout(5, TimeUnit.SECONDS).build();
Future<Boolean> conversion = converter.convert(wordFile).as(DocumentType.DOCX).to(target).as(DocumentType.PDF)
.schedule();
converter.shutDown();

添加conversion.get() 会引发以下错误

默认情况下，tomcat 9 作为 Windows 服务，在“本地服务”下运行。将登录更改为本地系统帐户，上述错误消失了。

但是，现在我遇到了另一个错误：

同样，我相信这与我无法弄清楚的访问权限有关，有谁知道为什么显示此消息？请注意，即使使用包含单个字符的简单 .docx 文件，也会显示相同的堆栈跟踪。

Word 文档和 PDF 文档的File对象需要明确包含其位置的路径。

下面的示例假定两个文档使用相同的位置 - 这与baseFolder位置（转换器放置其临时文件的位置）相同：

final String dir = "C:/tmp/conversions/";

File wordFile = new File(dir + "sample.docx");
File pdfFile = new File(dir + "sample.pdf");
        
IConverter converter = LocalConverter.builder()
        .baseFolder(new File(dir))
        .workerPool(20, 25, 2, TimeUnit.SECONDS)
        .processTimeout(5, TimeUnit.SECONDS)
        .build();
        
Future<Boolean> conversion = converter
        .convert(wordFile).as(DocumentType.DOCX)
        .to(pdfFile).as(DocumentType.PDF)
        .schedule();
        
converter.shutDown();

因此，在上面的示例中，我从conversions目录中已经存在的 Word 文档开始。

仅作记录，我使用以下依赖项：

<dependency>
    <groupId>com.documents4j</groupId>
    <artifactId>documents4j-api</artifactId>
    <version>1.1.3</version>
</dependency>
<dependency>
    <groupId>com.documents4j</groupId>
    <artifactId>documents4j-local</artifactId>
    <version>1.1.3</version>
</dependency>
<dependency>
    <groupId>com.documents4j</groupId>
    <artifactId>documents4j-transformer-msoffice-word</artifactId>
    <version>1.1.3</version>
</dependency>

更新：

对于 Tomcat，我不是将其作为 Windows 服务安装，而是使用此页面中的“64 位 Windows zip”作为独立服务安装。

我创建了一个非常基本的 servlet，除了运行转换代码之外什么都不做——与我在这个答案中显示的代码相同。

我尝试了 2 个不同的目录位置：一个在 CATALINA_BASE 外部，一个与 CATALINA_BASE 相同。

一切都按预期工作，没有问题，或者需要管理任何权限等。我的用户 ID 在 PC 上具有 Windows 管理员权限。
