documents4j在转换后不保存文件

Question

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

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

此外，调试显示了以下内容：

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()会抛出以下错误

Answer 1

Word文档和File文档的PDF对象需要显式包含其位置的路径。

下面的示例假设两个文档使用相同的位置-并且这与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，我从已经在conversions目录中的Word文档开始。

为了便于记录，我使用了以下依赖项：

<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，我没有将其作为Windows服务安装，而是使用this页面上的"64位Windows zip“将其安装为独立的。

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

我尝试了两个不同的目录位置:一个在CATALINA_BASE外部，另一个与CATALINA_BASE相同。

一切按预期运行，没有任何问题，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。

Answer 2

默认情况下，tomcat 9作为一项windows服务，在“本地服务”下运行。将登录更改为本地系统帐户后，上述错误消失。

然而，现在我遇到了另一个错误：

再一次，我相信这与访问权限有关，但我无法理解，有人知道为什么会显示这条消息吗？请注意，即使是包含单个字符的简单.docx文件，也会显示相同的堆栈跟踪。
