一般页面都是.jsp页面，所以要把.jsp转换成html，在生成pdf，在网上找了好多方法，只有用一个插件，wkhtmltopdf-0.8.3.exe，生成的pdf会相对的好看。
先附上我做的.jsp页面。

我用el表达式动态得到数据库里面的数据，然后在导出方法中，定义了from表单，把整个jsp源码获取到。
页面的效果：
下面附上后台的方法：
import java.io.BufferedInputStream;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.io.OutputStreamWriter;
import java.io.UnsupportedEncodingException;
import java.net.URLDecoder;
import java.net.URLEncoder;
import java.util.ArrayList;
import java.util.List;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import com.check.test.HtmlToPdf;
/** * 将html转成pdf * @param request * @param response * @return */ @RequestMapping(params = "reqCode=exportAssurehistoryPDF") public ModelAndView exportAssurehistoryPDF(HttpServletRequest request,HttpServletResponse response){ try { request.setCharacterEncoding("UTF-8"); } catch (UnsupportedEncodingException e2) { e2.printStackTrace(); } String h = request.getParameter("htmlContent"); System.out.println(h); String pPath=this.writeHtmlToFile(h, "assurehistory"); HtmlToPdf.convert(pPath+"/assurehistory.html", pPath+"/assurehistory.pdf"); try { //Thread.sleep(1000); response.setContentType("application/pdf"); response.addHeader("content-disposition", "attachment;filename="+ URLEncoder.encode("个人担保信息查询统计.pdf", "UTF-8")); File file = new File(pPath+"/assurehistory.pdf"); InputStream fis = new BufferedInputStream(new FileInputStream(file)); byte[] buffer = new byte[fis.available()]; fis.read(buffer); fis.close(); OutputStream os = response.getOutputStream(); os.write(buffer); os.flush(); os.close(); } catch (UnsupportedEncodingException e1) { e1.printStackTrace(); }catch (FileNotFoundException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } return null; } /** * 将内容写入html文件 * @param content * @param htmlName * @return */ private String writeHtmlToFile(String content,String htmlName) { String path = ""; try { path = URLDecoder.decode(AssurehistoryController.class.getClassLoader().getResource("pdfFile/").getFile(), "utf-8"); } catch (UnsupportedEncodingException e) { e.printStackTrace(); } System.out.println(path); content=content.replace("<div class="box" style="height:430px;overflow:auto">", "<div class="box" style="overflow:auto">"); content=content.replace("button", "hidden").replace("HEIGHT: 430px", ""); File file = new File(path + htmlName+".html"); BufferedWriter bw = null; try { bw = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(file),"utf-8")); bw.write("<!DOCTYPE html><html lang="en">"); bw.write(content); bw.write("</html>"); bw.flush(); } catch (IOException e) { e.printStackTrace(); } finally { if (bw != null) { try { bw.close(); } catch (IOException e) { e.printStackTrace(); } } } return file.getParent(); }
然后在定义一个HtmlToPdf类，你也可以把这个类的方法单独拿出来。
package com.check.test;
import java.io.File;
import java.io.UnsupportedEncodingException;
import java.net.URLDecoder;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.Locale;
import com.eloan.app.assurehistory.controller.AssurehistoryController;
public class HtmlToPdf {
/**
* html转pdf
* @param srcPath html路径，可以是硬盘上的路径，也可以是网络路径
* @param destPath pdf保存路径
* @return 转换成功返回true
*/
public static boolean convert(String srcPath, String destPath){
//wkhtmltopdf在系统中的路径
String str="";
try {
str = URLDecoder.decode(AssurehistoryController.class.getClassLoader().getResource("pdfFile/wkhtmltopdf-0.8.3.exe").getFile(), "utf-8");
} catch (UnsupportedEncodingException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
String path = new File(str).getPath();
File file = new File(destPath);
File parent = file.getParentFile();
//如果pdf保存路径不存在，则创建路径
if(!parent.exists()){
parent.mkdirs();
}
StringBuilder cmd = new StringBuilder();
cmd.append(path);
cmd.append(" ");
cmd.append(srcPath);
cmd.append(" ");
cmd.append(destPath);
boolean result = true;
try{
Process proc = Runtime.getRuntime().exec(cmd.toString());
proc.waitFor();
}catch(Exception e){
result = false;
e.printStackTrace();
}
return result;
}
}
最后，还有个重要的，就是wkhtmltopdf-0.8.3.exe，这个大家可以在网上免费下载，我把它放在我项目的src/main/java下面
最后，生成的pdf效果是：
