HTML转PDF(java)

大家好,我是傻明蚕豆,最近搞了一个html转pdf,在这里把知识记录下来,希望对大家有帮助。

废话不多说,直奔主题。首先把你想要生成的pdf内容做成html模版,然后把数据导入到模版中,再生成一个pdf文件。

准备html如下图所示:

html模版

html代码:

<html>

<head>

    <link rel="stylesheet" href="F:/read/jianli/jianli.css"></link>

</head>

<body >

<div id="div1" style="background-image:url('F:/read/jianli/images/t01ed5a885549b6bf3b.jpg');">

<table border="1" width="100%" height="100%" align="center" valign="middle" align="center" cellpadding="10">

<tr>

    <th colspan="7">我的个人简介</th>

</tr>

<tr>

    <th>姓名:</th>

    <td>${name}</td>

    <th>年龄:</th>

    <td>${age}</td>

    <th>民族:</th>

    <td>${nation}</td>

    <td rowspan="3" width="100"><img src="F:/read/jianli/images/small.png"/></td>

</tr>

<tr>

    <th >出生日期:</th>

    <td>${birthday}</td>

    <th >政治面貌:</th>

    <td>${politicsVisage}</td>

    <th >学历:</th>

    <td>${educationBackground}</td>

</tr>

<tr>

    <th >专业:</th>

    <td>${major}</td>

    <th >毕业学校:</th>

    <td>${school}</td>

    <th >邮编:</th>

    <td>${postcode}</td>

</tr>

<tr>

    <th >爱好:</th>

    <td>${hobby}</td>

    <th >籍贯:</th>

    <td>${nativePlace}</td>

    <th>邮箱:</th>

    <td colspan="2">${email}</td>

</tr>

<tr>

    <th height="160"> 自我介绍:</th>

    <td colspan="6">

    <p>来自广东省某个镇的一个小村庄里,我爱计算机,我爱...</p>

    <p>来自广东省某个镇的一个小村庄里,我爱JAVA,我爱...</p>

    <p>来自广东省某个镇的一个小村庄里,我爱Spring全家桶,我爱...</p>

    <p>注意:标签必须闭合</p>

    </td>

</tr>

</table>

</div>

</body>

</html>

css代码:

th{

background-color: BurlyWood;

}

java代码:

private static void test(){

    Map<String ,Object> map=new HashMap<>();

    map.put("name","傻明蚕豆");

    map.put("age","18");

    map.put("nation","汉族");

    map.put("birthday","19810808");

    map.put("politicsVisage","团员");

    map.put("educationBackground","大学");

    map.put("major","电子技术");

    map.put("school","青山大学");

    map.put("postcode","528143");

    map.put("hobby","吃喝拉撒");

    map.put("nativePlace","粤");

    map.put("email","1060120317@qq.com");

    File modelFile = new File("F:/read/jianli");

    String htmlName = "jianli.html";

    String cssPath = "F:/read/jianli/jianli.css";

    String pdfPath ="F:/read/jianli/"+System.currentTimeMillis()+".pdf";

    try {

        createPDF(modelFile,htmlName, cssPath, pdfPath, map);

        System.out.println("success");

    }catch (Exception e){

        e.printStackTrace();

    }

}

private static void createPDF(File modelFile,String htmlName,String cssPath,String pdfPath,Map<String, Object> paramMap) throws Exception{

    Configuration configuration = new Configuration(Configuration.VERSION_2_3_23);

    configuration.setObjectWrapper(new DefaultObjectWrapper(Configuration.VERSION_2_3_23));

    configuration.setDefaultEncoding("UTF-8");  //这个一定要设置,不然在生成的页面中 会乱码

    configuration.setDirectoryForTemplateLoading(modelFile);

    //获取或创建一个模版。

    Template template = configuration.getTemplate(htmlName);

    StringWriter stringWriter = new StringWriter();

    BufferedWriter writer = new BufferedWriter(stringWriter);

    template.process(paramMap, writer); //把值写进模板

    String htmlStr = stringWriter.toString();

    writer.flush();

    writer.close();

    FileOutputStream outFile = new FileOutputStream(pdfPath);

    InputStream cssInputStream = new FileInputStream(cssPath);

    ByteArrayInputStream htmlInputStream = new ByteArrayInputStream(htmlStr.getBytes("UTF-8"));

    Document document = new Document();

    try {

        PdfWriter pdfWriter = PdfWriter.getInstance(document, outFile);

        document.open();

        FontProvider provider = new FontProvider();

        XMLWorkerHelper.getInstance().parseXHtml(pdfWriter, document, htmlInputStream, cssInputStream, Charset.forName("UTF-8"),provider);

    } catch (Exception e) {

        e.printStackTrace();

        throw e;

    }finally {

        try {

            document.close();

        } catch (Exception e) {

            e.printStackTrace();

        }

        try {

            htmlInputStream.close();

            cssInputStream.close();

        } catch (Exception e) {

            e.printStackTrace();

        }

}

}

/**

* 字体

*/

private static class FontProvider extends XMLWorkerFontProvider {

    public Font getFont(final String fontname, final String encoding, final boolean embedded, final float size, final int style, final BaseColor color) {

        BaseFont bf = null;

        try {

            bf = BaseFont.createFont("STSong-Light", "UniGB-UCS2-H", BaseFont.NOT_EMBEDDED);

        } catch (Exception e) {

            e.printStackTrace();

        }

        Font font = new Font(bf, size, style, color);

        font.setColor(color);

        return font;

    }

}

运行结果生成如下图:

生成的pdf

注意:Html标签必须闭合

这时候发现背景图没有,经过一波操作,改css样式、把背景图放到table、设置浮动,结果还是不行。

希望有大神可以看到帮忙解决这个问题。

谢谢观看,再见!
