配置对应jar
编写HTML模板
编写导出PDF工具类
业务中调用PDF工具类
背景
市场上Java导出word、execl较多，比如POI等。反而Java导出PDF实现开源的少之又少。为了防止用户修改自己公司定制的一些文件，因此将一些数据导出PDF，以便用户阅读。对于Java导出PDF，市场上主要有：1.iText实现HTML2PDF，速度快、纠错能力差、支持中文、只支持Unicode编码，一种中文格式，样式单一，开源。2.Flying Ssauser实现HTML2PDF，纠错能力差、支持多种中文字体，部分样式不支持(css3中的部分样式不支持)，开源。3.速度快，纠错能力强，支持多种中文字体，商业不开源。
结合市场上的Java将HTML导出PDF开源，都不符合自己需求。因此，自己综合市场的技术，自己采用Flying Ssauser实现导出PDF定制开发。
配置maven依赖
现在JavaEE开发都是采用maven项目，方便jar管理和维护。开发Java将HTML导出PDF所需要的jar，在pom.xml文件中配置如下：
<!-- https://mvnrepository.com/artifact/org.xhtmlrenderer/flying-saucer-pdf-itext5 -->
<dependency>
<groupId>org.xhtmlrenderer</groupId>
<artifactId>flying-saucer-pdf-itext5</artifactId>
</dependency>
编写HTML模板
template.html代码如下：
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>PDF 模版</title>
<style type="text/css">

首先，动态变更的数据用字符串变量取代，在Java后台进行替换。其次，对于PDF的分页，在HTML模板中，采用css3的@page进行分页操作。再次，HTML模板中的字体采用window字体库中英文的宋体字体。

// 直接往response的输出流中写pdf
OutputStream outputStream = response.getOutputStream();
// 下载格式设置
response.setContentType("APPLICATION/OCTET-STREAM");
response.setHeader("Content-Disposition", "attachment; filename=" + fileName + ".pdf");
ITextRenderer renderer = new ITextRenderer();
renderer.setDocumentFromString(templateContent);
// 解决中文支持
ITextFontResolver fontResolver = renderer.getFontResolver();
fontResolver.addFont("C:/windows/fonts/simsun.ttc", BaseFont.IDENTITY_H,
BaseFont.NOT_EMBEDDED);
renderer.layout();
renderer.createPDF(outputStream);
outputStream.close();
System.out.println("create pdf done!!");

private ServletContext servletContext;
public void setServletContext(ServletContext sc) {
this.servletContext = sc;
//System.out.println("项目的绝对路径为："+servletContext.getRealPath("/"));

}
总结
自此，整个Java将HTML导出PDF开发过程，大功告成。开发过程中，需要注意的是字体、分页、输出流。
