Question

我已经将FOP版本从fop 1.1升级到了fop 2.3版本

org.apache.fop.events.LoggingEventListener processEvent图像未找到。

下面是为升级而修改的代码段。使用FOP 2.3的Master View代码

代码：

  TransformerFactory factory = TransformerFactory.newInstance();
  Transformer transformer = factory.newTransformer();

  FOUserAgent foUserAgent = fopFactory.newFOUserAgent();

  //foUserAgent.setURIResolver( this.getURIResolver() );
  transformer.setURIResolver(this.getURIResolver());

  Fop fop = null;
  Source src = new StreamSource(new ByteArrayInputStream(foDoc));

  if (this.getContentType().equals("application/pdf"))
  {
    fop = fopFactory.newFop(MimeConstants.MIME_PDF, foUserAgent, os);
  }
  else if (this.getContentType().equals("application/postscript"))
  {
    fop = fopFactory.newFop(MimeConstants.MIME_POSTSCRIPT, foUserAgent, os);
  }

查看fop 2.3的代码

protected static final FopFactory fopFactory = FopFactory.newInstance(new File(".").toURI(), resolver);

XSLT代码

<fo:external-graphic src = "stylesheets/Anthem_Join_In.bmp"/>

Resolver的API已更改，并且记录不充分。此代码在JSF webApp中对我有效（fop 2.3）。

files:
"/etc/nginx/conf.d/proxy.conf" :
    mode: "000644"
    owner: root
    group: root
    content: |
        server{
            if ($http_x_forwarded_proto = "http") {
                return 301 https://$host$request_uri;
            }
        }

项目中的其余先前代码保持不变。我没有使用Transformer.setURIResolver（...）

xml fop代码如下：

final ServletContext sc = (ServletContext) FacesContext.getCurrentInstance().getExternalContext().getContext();

// Create ServletContext resource Resolver
ResourceResolver resolver = new ResourceResolver() {
    @Override
    public Resource getResource(URI uri) throws IOException {
        return new Resource(sc.getResourceAsStream(uri.toASCIIString()));
    }

    @Override
    public OutputStream getOutputStream(URI uri) throws IOException {
        URL url = sc.getResource(uri.toASCIIString());
        return url.openConnection().getOutputStream();
    }
};

// Buid the factory
FopFactoryBuilder builder = new FopFactoryBuilder(new URI(sc.getContextPath()), resolver);
FopFactory FOP_FACTORY = builder.build();

使用FOP 2.3版本时找不到FOP图像
