svg2pdf

在项目中遇到了svg转pdf，此处记录一下，方便以后使用。

此处使用直接下载的方式，存在自己电脑默认下载目录。

1、maven依赖：

<groupId>com.itextpdf</groupId>

<artifactId>itextpdf</artifactId>

</dependency>

<groupId>com.itextpdf</groupId>

<artifactId>itext-pdfa</artifactId>

</dependency>

<groupId>com.itextpdf</groupId>

<artifactId>itext-xtra</artifactId>

</dependency>

<groupId>com.itextpdf.tool</groupId>

<artifactId>xmlworker</artifactId>

</dependency>

<groupId>com.lowagie</groupId>

<artifactId>itext</artifactId>

</dependency>

<groupId>com.kenai.nbpwr</groupId>

<artifactId>org-apache-batik-all</artifactId>

</dependency>

<groupId>org.eclipse.birt.runtime</groupId>

</dependency>

<groupId>org.eclipse.birt.runtime.3_7_1</groupId>

</dependency>

2、html代码：

<%@ page language="java" contentType="text/html; charset=UTF-8"

pageEncoding="UTF-8"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<html>

<head>

<title>Insert title here</title>

$(function(){

$("#svgToPDF").click(function(){

var svgHtml = $("#svgDiv").find("svg")[0];

var XMLS = new XMLSerializer();

var svg = XMLS.serializeToString(svgHtml);

$("#svgHtml").val(svg);

$("#svgForm").submit();

});

</script>

3、control层：

@RequestMapping(value="exportPDF")

@ResponseBody

public String exportPdfFile(HttpServletRequest request,HttpServletResponse response,String svg) throws Exception {

Calendar cal = Calendar.getInstance();

String pdfName = String.valueOf(cal.getTimeInMillis());

response.reset();

response.addHeader("Content-Type", "application/pdf");

response.addHeader("Content-Disposition", "attachment; filename="+ pdfName + ".pdf");

ByteArrayOutputStream baos = new ByteArrayOutputStream();

PDF.testPDf(baos,svg);

baos.writeTo(response.getOutputStream());

baos.close();

return "success";

}

注意：因为使用的是下载方式，此方式必须使用form表单提交，若使用ajax方式不会下载成功
