Java使用iText根据HTML模板生成PDF报表

作者:互联网

1.第一步先简单做个HTML页面,正常来说前端直接将整个HTML页面后端处理

  直接复制使用即可

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8"/>
    <title>Title</title>
    <style>
        body {
            font-family: SimHei;
        }

        input {
            -webkit-appearance: checkbox;
        }
        table {
            font-size: 8px;
            color: #333333;
            width: 100%;
            border-width: 1px;
            border-color: #729ea5;
            border-collapse: collapse;
        }

        th {
            font-size: 8px;
            background-color: #acc8cc;
            border-width: 1px;
            padding: 8px;
            border-style: solid;
            border-color: #729ea5;
            text-align: center;
        }

        tr {
            background-color: #d4e3e5;
        }

        td {
            font-size: 8px;
            border-width: 1px;
            padding: 8px;
            border-style: solid;
            border-color: #729ea5;
            text-align: center;
        }

        #div-head {
            line-height: 50px;
            text-align: center
        }
    </style>
</head>

2.导入pom依赖

<dependency>
            <groupId>com.itextpdf</groupId>
            <artifactId>itextpdf</artifactId>
            <version>5.5.11</version>
        </dependency>

        <dependency>
            <groupId>com.itextpdf.tool</groupId>
            <artifactId>xmlworker</artifactId>
            <version>5.5.11</version>
        </dependency>


        <!-- freemarker -->
        <dependency>
            <groupId>org.freemarker</groupId>
            <artifactId>freemarker</artifactId>
        </dependency>

        <!--Flying Saucer是基于iText的,支持对CSS高级特性的解析。-->
        <!-- https://mvnrepository.com/artifact/org.xhtmlrenderer/flying-saucer-pdf -->
        <dependency>
            <groupId>org.xhtmlrenderer</groupId>

            <version>2.0.8</version>
        </dependency>

  

3.编写工具类

  正常来说前端直接将整个HTML页面后端处理,这里就直接渲染生成了

package com.example.demo.util;


import com.itextpdf.text.Document;
import com.itextpdf.text.DocumentException;
import com.itextpdf.text.pdf.PdfWriter;
import com.itextpdf.tool.xml.XMLWorkerFontProvider;
import com.itextpdf.tool.xml.XMLWorkerHelper;
import freemarker.template.Configuration;
import freemarker.template.Template;

import java.io.*;
import java.nio.charset.Charset;
import java.util.Map;

/**
* @Author Felix
* @Date 2021-10-29 10:52:51
* @Description:
*/
public class PdfUtils {

private static final String DEST = "D:\\ANTECS2\\demoExcel\\src\\main\\resources\\pdfFile\\test.pdf";
private static final String FONT = "D:\\ANTECS2\\demoExcel\\src\\main\\resources\\static\\font\\SimHei.ttf";
private static final String FILECATALOG = "D:\\ANTECS2\\demoExcel\\src\\main\\resources\\templates";

private static Configuration freemarkerCfg;

static {
freemarkerCfg = new Configuration();
try {
freemarkerCfg.setDirectoryForTemplateLoading(new File(FILECATALOG));
} catch (IOException e) {
e.printStackTrace();
}
}

public static void createPdf(String content) throws IOException, DocumentException {
// step 1
Document document = new Document();

//返回给前端的话就使用ByteArrayOutputStream加载到域中,替换掉下面的PdfWriter.getInstance(document, stream)即可
//OutputStream stream = new ByteArrayOutputStream();

// step 2
PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream(FILECATALOG));
// step 3
document.open();
// step 4
XMLWorkerFontProvider fontImp = new XMLWorkerFontProvider(XMLWorkerFontProvider.DONTLOOKFORFONTS);
fontImp.register(FONT);
XMLWorkerHelper.getInstance().parseXHtml(writer, document,
new ByteArrayInputStream(content.getBytes()), null, Charset.forName("UTF-8"), fontImp);
// step 5
document.close();


}

/**
* freemarker渲染html
*/
public static String freeMarkerRender(Map<String, Object> data, String htmlTmp) {
Writer out = new StringWriter();
try {
// 获取模板,并设置编码方式
Template template = freemarkerCfg.getTemplate(htmlTmp);
// template.setEncoding("UTF-8");
// 合并数据模型与模板
//将合并后的数据和模板写入到流中,这里使用的字符流
template.process(data, out);
out.flush();
return out.toString();
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
out.close();
} catch (IOException ex) {
ex.printStackTrace();
}
}
return null;
}

}

4.测试

  

@Test
    public void pdfTest() throws IOException, DocumentException {
        //模板路径
        String fileTemp = "index.html";
        //模板渲染,其实页面没有用到,假数据
        Map<String, Object> data = new HashMap<>();
        data.put("data",123);
        PdfUtils.createPdf(PdfUtils.freeMarkerRender(data, fileTemp));

    }

 

完成
