Ofbiz 用FOP生成PDF文件中文无法显示的解决方案

在开发过程中，发现生成的PDF文件中，所有中文都不能显示，以”#“表示。

在ofbiz中，生成pdf的过程是：

1、访问xxx.pdf的url.

2、controller.xml中对*.pdf配置如下：

<handler name="screenfop" type="view" class="org.ofbiz.widget.screen.ScreenFopViewHandler"/>

...

<view-map name="PicklistReport.pdf" type="screenfop" page="component://warehouse/widget/warehouse/screens/shipping/ShippingScreens.xml#PicklistReportPDF" content-type="application/pdf" encoding="none"/>

3、在ScreenFopViewHandler.java中，先把PicklistReport.fo.ftl渲染成xml

        // render and obtain the XSL-FO
        Writer writer = new StringWriter();
        FopFactory fopFactory = ApacheFopFactory.instance();
            ScreenRenderer screens = new ScreenRenderer(writer, null, htmlScreenRenderer);
            screens.populateContextForRequest(request, response, servletContext);
            // this is the object used to render forms from their definitions
            screens.getContext().put("formStringRenderer", new FoFormRenderer(request, response));
            screens.render(page);

  然后由apache的FOP(Formatting Objects Processor)对xml渲染，生成pdf文件，并放回到response中输出：

        ByteArrayOutputStream out = new ByteArrayOutputStream();
        TransformerFactory transFactory = TransformerFactory.newInstance();
        try {
            Fop fop = fopFactory.newFop(contentType, out);
            Transformer transformer = transFactory.newTransformer();
            // set the input source (XSL-FO) and generate the output stream of contentType
            Reader reader = new StringReader(writer.toString());
            Source src = new StreamSource(reader);
            // Get handler that is used in the generation process
            Result res = new SAXResult(fop.getDefaultHandler());
                // Transform the FOP XML source
                transformer.transform(src, res);
                // We don't want to cache the images that get loaded by the FOP engine
                fopFactory.getImageFactory().clearCaches();
                // set the content type and length
                response.setContentType(contentType);
                response.setContentLength(out.size());
                // write to the browser
                    out.writeTo(response.getOutputStream());
                    response.getOutputStream().flush();

又一次看到中文被鄙视了，Apache FOP中不支持任务中文字体，所以要做下边三步，才能使pdf中的中文正常显示：

1、用FOP生成黑体字体配置文件simhei.xml，并把windows下的黑体文件simhei.ttf放在相同的目录下。在openb2c 中为：

%OPENB2C_HOME%\hot-deploy\opentaps-common\lib\DejaVu\

生成simhei.xml的命令为：

java -classpath framework\webapp\lib\fop-0.93.jar;framework\base\lib\avalon-framework-4.2.0.jar;framework\webapp\lib\batik-all-1.6.jar;framework\base\lib\commons\commons-logging.jar;framework\base\lib\commons\commons-io-1.4.jar;framework\base\lib\serializer.jar;framework\base\lib\xalan.jar;framework\base\lib\xml-apis-2.8.1.jar;framework\webapp\lib\xmlgraphics-commons-1.1.jar org.apache.fop.fonts.apps.TTFReader -ttcname "SimHei" C:\WINDOWS\Fonts\simhei.ttf D:\simhei.xml

2、修改ofbiz中fop的配置文件fop.xconf

添加字体：simhei

       <font metrics-url="simhei.xml" kerning="yes" embed-url="simhei.ttf">
            <font-triplet name="simhei" style="normal" weight="normal"/>
        </font>

3、修改*.fo.ftl模板文件，把font-family改为simhei

<fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format"
    font-family="simhei">

重启看到pdf能正常显示中文了！

apache-ofbiz-13.07.01中生成simhei.xml

java -classpath ..\\framework\\base\\lib\\fop-1.1.jar;../framework\base\lib\avalon-framework-4.2.0.jar;../framework\webapp\lib\batik-all-1.7.jar;../framework\base\lib\commons\commons-logging-1.1.2.jar;../framework\base\lib\commons\commons-io-2.4.jar;../framework\base\lib\serializer-2.9.1.jar;../framework\base\lib\xalan-2.7.1.jar;../framework\base\lib\xml-apis-2.9.1.jar;../framework\base\lib\xmlgraphics-commons-1.5.jar org.apache.fop.fonts.apps.TTFReader -ttcname "SimHei" simhei.ttf simhei.xml
