Question

我目前正在尝试使用Java将高级Word文档（.DOCX）转换为PDF。

为了生成Word文档，我使用apache poi@3.15。他们内置了PDF转换器，尽管它破坏了文档格式。

最终，我最终使用了基于云的API（收费），感觉真是令人讨厌。但是今天，我发现了document4j项目，这让我非常兴奋。

我已购买了运行Windows的VPS，其唯一目的是将.docx文件转换为.pdf文件，并且可以访问。 document4j / local-demo也可以正常工作，并且能够将我的.docx文件很好地转换为.pdf。

除了Javadocs之外，在线文档似乎非常有限，除了Javadocs之外，它对我的帮助不及编辑器中的intellisense。

有人可以帮我吗？

相关代码：

IConverter converter = RemoteConverter.builder()
                    .baseFolder(null)
                    .workerPool(20, 25, 2, TimeUnit.SECONDS)
                    .requestTimeout(10, TimeUnit.SECONDS)
                    .baseUri("http://xxx.xxx.xxx.xxx:1337")
                    .build();

                File pdfFile = File.createTempFile(fileName, ".pdf");
                pdfFile.deleteOnExit();

                converter.convert(data).as(DocumentType.DOCX).to(pdfFile).as(DocumentType.PDF).execute();

编辑：不幸的是，使用java -jar ./documents4j-client-standalone-1.0.3-shaded.jar http://xxx.xxx.xxx.xxx:1337可以使用events。

Answer 1

这是一个明显的依赖版本冲突。检查您使用的是哪个版本的Glassfish以及取决于哪个版本的Glassfish文档。运行 mvndependency：tree 可以帮助您解决这一问题。

Answer 2

我的问题与此问题类似，并且通过创建自定义HTTP请求得以解决：

Custom HttpClient for RemoteConverter of Documents4j

远程使用document4j将DOCX转换为PDF
