后台打印pdf文件
不知道怎么描述，直接贴了代码了。有问题可以加Q群790537003讨论。先贴效果图：
controller直接调用下面方法 就能直接下载pdf到本地了
public static void invoicePdf(HttpServletResponse response, List> data) {
Document document = new Document(new Rectangle(285, 375),-30,-30,0,0); //左 右 上 下
try {
// 告诉浏览器用什么软件可以打开此文件
response.setHeader("content-Type", "application/pdf");
// 下载文件的默认名称
SimpleDateFormat sdf = TimeUtils.sdf("yyyyMMddHHmmss");
response.setHeader("Content-Disposition", "attachment;filename=Invoice" + sdf.format(new Date()) + ".pdf");
PdfWriter.getInstance(document, response.getOutputStream());
document.open();
//字体设置
//由于itext不支持中文，所以需要进行字体的设置，我这里让itext调用windows系统的中文字体，
//找到文件后，打开属性，将文件名及所在路径作为字体名即可。
//创建BaseFont对象，指明字体，编码方式,是否嵌入
BaseFont bf = BaseFont.createFont("/font/SIMYOU.TTF", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);
//创建Font对象，将基础字体对象，字体大小，字体风格
document.open();
HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();
String path = request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort() + "/";
for(Map map : data) {
createTableInvoice(document, map, path);
}
/*int size = wrList.size();
int pageSize = 37; //每页大小
int pageTotal = size/pageSize+1; //总页数
for(int i=1; i<=pageTotal; i++) {
int startNum = (i-1)*pageSize+1; //第i页开始编号
int endNum = i*pageSize > size ? size : i*pageSize; //第i也结束编号
