Question

从Apache FOP生成PDF时，我收到了波纹管错误，

  FopFactory fopFactory = FopFactory.newInstance(new File("/Users/vinurip/cloud/Stripe/Full/pdfboxtut/src/main/resources/fop.xconf"));
    OutputStream out = new BufferedOutputStream(new FileOutputStream(new File(outFile)));
    Fop fop = fopFactory.newFop(MimeConstants.MIME_PDF, out);

OutFile是一个空的pdf文件位置。 fop.xconf与FOP源中的相同

只有在启用字体自动检测时才会出现此问题

Answer 1

您可以使用搜索引擎找到一些信息 - 例如。 https://qnalist.com/questions/6434450/pdfbox-2-0-and-batik - 虽然这些不是很有用......

我的解决方法是使用<directory recursive="true">/usr/share/fonts</directory>而不是<auto-detect />。

Answer 2

由于Apache FOP和Apache PDFBox / FontBox之间的Maven依赖性不匹配，我遇到了这个问题。

我在撰写本文时将项目的pom.xml迁移到最新的依赖版本，从而解决了这个问题：

<dependency>
  <groupId>org.apache.xmlgraphics</groupId>
   <artifactId>fop</artifactId>
   <version>2.2</version>
</dependency>
<dependency>
   <groupId>org.apache.pdfbox</groupId>
   <artifactId>pdfbox</artifactId>
   <version>2.0.9</version>
</dependency>
<dependency>
  <groupId>org.apache.pdfbox</groupId>
  <artifactId>fontbox</artifactId>
  <version>2.0.9</version>
</dependency>

要迁移到Apache FOP 2.2，请按照embedding guidelines和migration guideslines。

进行操作

当字体自动检测启用时，FOP给出NoSuchMethodError
