poi实现word内容替换并且转pdf和制作模版
1，制作模版（请把模版制作好，尤其是下面的解决方法，一定要去修改）

（重要的问题说三遍！！！）
制作模版
2，在项目打成jar包上线以后，只能在jar包同级替换文档和pdf，这是个坑，大家伙注意，要用这种方式
ApplicationHome h = new ApplicationHome(this.getClass());
File jarF = h.getSource();
jarF.getParent()+File.separator+wordName.toString()
3，替换方法
先通过步骤2中的方法获取到模版，模版可以放在数据库，或者项目中，有文件服务器的就请忽略第二步
Map params = new LinkedHashMap<>();
params.put("${项目名称}", dbglZbtzs.getZbxmmc());
params.put("${项目负责人}", dbglZbtzs.getXmfzr());
XWPFDocument document = DocxUtil.getDocument(fileContent);
//poi模版替换
DocxUtil.replaceWord(document, params);
//poi实现讲替换后的docx生成到某个路径下面
DocxUtil.exportDocx(document,jarF.getParent()+"/",wordName.toString());
4，word转pdf
PdfOptions options = PdfOptions.create();
//替换过数据的docx的路径
inputStream1 = new FileInputStream(new File(wordPath1.toString()));
//pdf生成路径
FileOutputStream outputStream = new FileOutputStream(new File(rootPath.toString()));
//word转pdf WordToPDF.wordConverterToPdf(inputStream1,outputStream,options);
5，DocxUtil
