java使用flySaucer实现html转pdf

1、引入maven包

            <dependency>
                <groupId>com.itextpdf</groupId>
                <artifactId>itextpdf</artifactId>
                <version>5.5.12</version>
            </dependency>

            <dependency>
                <groupId>org.xhtmlrenderer</groupId>
                <artifactId>flying-saucer-pdf-itext5</artifactId>
                <version>9.1.6</version>
            </dependency>

2、FlySaucerUtil示例

/**
     *将htmlCode转换为pdf文件
     *
     * @param htmlCode  其中body体必须包含字体样式设置，否则无法识别汉字。
     *                    字体样式设置举例：style='font-family:SimSun'
     * @param pdfPath 实际存在的全路径pdf文件
     */
    public static void htmlCodeToPdf(String htmlCode, String pdfPath) {
        OutputStream os =null;
        try {
            os=new FileOutputStream(pdfPath);
            ITextRenderer renderer = new ITextRenderer();
            ITextFontResolver fontResolver = renderer.getFontResolver();
            fontResolver.addFont("/fonts/simsun.ttc", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);
            renderer.setDocumentFromString(htmlCode);
            renderer.layout();
            renderer.createPDF(os);
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        }catch (IOException e) {
            e.printStackTrace();
        } catch (DocumentException e) {
            e.printStackTrace();
        }finally {
            if(null!=os){
                try {
                    os.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
    }
}
