Java 生成pdf表格文档

最近在工作做一个泰国的项目，应供应商要求，需要将每天的交易生成pdf格式的报表上传到供应商的服务器，特此记录实现方法。废话不多说，直接上代码：

• THSarabunNew.ttf该文件是泰国字体自行网上下载即可

import com.itextpdf.text.*;

import com.itextpdf.text.pdf.BaseFont;

import com.itextpdf.text.pdf.PdfPCell;

import com.itextpdf.text.pdf.PdfPTable;

import com.itextpdf.text.pdf.PdfWriter;

import lombok.extern.slf4j.Slf4j;

import org.springframework.stereotype.Component;

import java.io.File;

import java.io.FileNotFoundException;

import java.io.FileOutputStream;

import java.io.IOException;
