java导出PDF详细教程+各种踩坑

直接上代码了

所需依赖：

    com.itextpdf
    itextpdf
    5.4.3


    com.itextpdf
    itext-asian
    5.2.0

控制层代码：

@RequestMapping("/downloadLogPDF")
public void downloadLogPDF(HttpServletRequest request, HttpServletResponse response) {
    tLogService.downloadLogPDF(request, response);
}

实现类代码：

 @Override
    public void downloadLogPDF(HttpServletRequest request, HttpServletResponse response) {
        //解析request中的请求参数
        String interfaceType = request.getParameter("interfaceType");
        String startDate = request.getParameter("startDate");
        String endDate = request.getParameter("endDate");
        List dataResult = getLogListByType(interfaceType, startDate, endDate);
        String fileName = "日志报表_" + startDate.split(" ")[0].toString() + "~" + endDate.split(" ")[0].toString() + ".pdf";
        String path = System.getProperty("user.dir") + "/downLoad/";
        //设置基础中文字体
        BaseFont bfChinese = null;
        try
