[wuning01234]

1、功能访问URL
window.location.href = '${ctx}/portfolio/userBonusData/pdfDown.do?s_time=' + s_time + '&e_time=' + e_time+"&oaId="+oaId;
2.service
public void pdfDown(String s_date, String e_date, String oaId, HttpServletRequest request, HttpServletResponse response) throws IOException, DocumentException {
OutputStream out =null;
PdfWriter writer = null;
try {
User user = (User) request.getSession().getAttribute("user");
List<Map> list = dealData(s_date, e_date, request, oaId, user);
//文件名称
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyyMMddhhmmssSSS");
String dateStr = dateFormat.format(new Date());
String fileName = "员工奖金变化" + dateStr; //
response.setContentType("application/pdf;charset=utf-8");
response.setHeader("Content-disposition", "attachment;filename=" + fileName + ".pdf");
Rectangle rect = new Rectangle(PageSize.A4);// 设置页面大小
rect.setBackgroundColor(Color.WHITE);// 页面背景色
// 页边空白
Document document = new Document(rect);// 创建一个Document
document.setMargins(10, 10, 30, 40); // 左，右，上，下
out = response.getOutputStream();
writer = PdfWriter.getInstance(document, out);// 创建书写器(Writer) 与 document对象关联，通过书写器可以将文档写入磁盘中
writer.setPdfVersion(PdfWriter.PDF_VERSION_1_7);// 设置PDF版本（默认1.4）

// 文档属性
document.addTitle("Title@sample"); // 标题
document.addAuthor("Author@nicaisheng");// 作者
document.addSubject("Subject@iText sample");// 主题
document.addKeywords("Keywords@iText");// 关键字
document.addCreator("Creator@iText");// 创建者
// 定义页头和页尾
/* HeaderFooter header = new HeaderFooter(new PdfPara);//new PdfParagraph("页头", 20,true), false
header.setAlignment(Element.ALIGN_CENTER);
HeaderFooter footer = new HeaderFooter(new Phrase("This is page "), new Phrase("."));
footer.setAlignment(Element.ALIGN_CENTER);
document.setHeader(header);
document.setFooter(footer);

//设置字体

//字体出错则按一下设置系统默认字体

document.open();// 打开文档
Paragraph title = new Paragraph("员工(" + oaId + ")" + s_date + "至" + e_date + "奖金变化", titleChinese);// 设置标题
title.setAlignment(Element.ALIGN_CENTER);// 设置对齐方式
title.setLeading(1f);// 设置行间距
document.add(title);
