intellij idea itext pdf在java中创建:当从localhost发出服务调用时,中文不起作用,但从main方法调用时工作正常
我正在尝试创建包含中文字符的pdf。 当我从main方法调用generatePdf()`时,它正在按预期工作。显示屏幕截图。但是,当我在weblogic server中部署并从浏览器“http://localhost:7001/PdfGeneration/itext/genpdf”调用时,它不会应用字体。我附上了屏幕截图
以下设置:
- weblogic版本:12.2.1
- Itextpdf,xmlworker:5.4.5
- 泽西岛版本:2.2
- Intellij IDE 2016.1.3
- JDK1.8
风格。css只包含以下内容
body {
font-family: "arial unicode ms";
}
代码:
@Path("itext")
@Api(value = "itext service")
public class iTextService {
//creating an object in main and calling the method works fine
//this part is commented when calling form server (localhost)
public iTextService() throws Exception {
generatePdf();
}
public static void main(String args[]) throws Exception {
iTextService obj = new iTextService();
return;
}
@GET
@Path("genpdf")
@Produces("application/pdf")
public void generatePdf() throws Exception {
ByteArrayOutputStream out = new ByteArrayOutputStream();
Document doc = new Document(PageSize.A4, 40, 40, 20, 10);
PdfWriter writer = PdfWriter.getInstance(doc, new FileOutputStream("testPDF.pdf"));
doc.open();
parseHTML(writer, doc);
doc.close();
}
//this method gives the artifact path
// screen shot of the artifact is shown
public String getFilePath() {
URL url = getClass().getClassLoader().getResource("/resource/");
String path = url.getPath();
try {
path = URLDecoder.decode(path, "utf-8");
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
path = new File(path).getPath();
return path;
}
public void parseHTML(PdfWriter writer, Document document) throws Exception {
//comment this when calling from main method
String pathToRes = getFilePath();
//case 1 : calling from main method
//byte[] encoded = Files.readAllBytes("style.css"));
//case 2: calling from browser (localhost)
byte[] encoded = Files.readAllBytes(Paths.get(pathToRes + "\\style.css"));
String style = new String(encoded);
CSSResolver cssResolver = new StyleAttrCSSResolver();
CssFile cssFile = XMLWorkerHelper.getCSS(new ByteArrayInputStream(style.getBytes()));
cssResolver.addCss(cssFile);
// HTML
XMLWorkerFontProvider fontProvider = new XMLWorkerFontProvider(XMLWorkerFontProvider.DONTLOOKFORFONTS);
//case 1
//fontProvider.register("ARIALUNI.ttf");
//case 2
fontProvider.register(pathToRes + "\\ARIALUNI.ttf");
//FontFactory.register(pathToFont + "\\ARIALUNI.ttf");
//FontFactory.setFontImp(fontProvider); //tried with these two along with exisitng code once
CssAppliers cssAppliers = new CssAppliersImpl(fontProvider);
HtmlPipelineContext htmlContext = new HtmlPipelineContext(cssAppliers);
htmlContext.setTagFactory(Tags.getHtmlTagProcessorFactory());
// Pipelines
PdfWriterPipeline pdf = new PdfWriterPipeline(document, writer);
HtmlPipeline html = new HtmlPipeline(htmlContext, pdf);
CssResolverPipeline css = new CssResolverPipeline(cssResolver, html);
// XML Worker
XMLWorker worker = new XMLWorker(css, true);
XMLParser parser = new XMLParser(worker);
parser.parse(new ByteArrayInputStream("<body><p>篆書 test</p></body>".getBytes()), Charset.forName("UTF-8"));
}
}

我发现了这个问题,我使用了itext提供的解析函数,它需要Inputstream,如下所示
public void parse(InputStream in, Charset charSet) throws IOException { this.charset = charSet; InputStreamReader reader = new InputStreamReader(in, charSet); this.parse((Reader)reader); }
最初我是这样做的
XMLParser parser = new XMLParser(worker); parser.parse(new ByteArrayInputStream(buildTemplate().getBytes("UTF-8")), Charset.forName("UTF-8"));
现在,我创建了一个Inputstream,然后将它传递给解析,它就工作了
InputStream is = new ByteArrayInputStream(buildTemplate().getBytes("UTF-8")); parser.parse(is, Charset.forName("UTF-8"));
出于某种原因,第一个方法在本地工作,但在托管时不工作
