一、首先制作word模版（这里需要注意的是文件后缀是docx不能是doc），${xxxx}是一会要替换的内容
关于为何必须是docx后缀可以看这篇文章/ct-csu/p/8178932.html
二、添加poi所需要的jar包文件，我用的maven对jar包进行管理
三、由于poi自身bug,会出现图片无法显示问题，这里需要自定义一个类继承XWPFDocument类，接下来使用的都是我们自己创建的这个类来操作word对象，这个
类对XWPFDocument进行了继承，所以不用担心会有什么问题
package com.newdo.base;import java.io.IOException;import java.io.InputStream;import org.apache.poi.openxml4j.opc.OPCPackage;import org.apache.poi.xwpf.usermodel.XWPFDocument;/*** word 导出工具类*/public class CustomXWPFDocument extends XWPFDocument{public CustomXWPFDocument(InputStream in) throws IOException {super(in);}public CustomXWPFDocument() {super();}public CustomXWPFDocument(OPCPackage pkg) throws IOException {super(pkg);}}
四、接下来就是导出word的工具类了

五、word转pdf文件我们需要用到一个jacob.jar（下载地址在文章下面 ）的一个包，将该jar包放入项目中的resources文件下的lib中
maven中引入本地jar包
同时需要将jacob中的dll文件放到自己的jdk环境中，将 dll 文件拷贝到 C:\Program Files\Java\jdk1.8.0_191\jre\bin (这是我自己的jdk位置)下，或者拷贝到当前项目运行的 jdk 的目录下的 jre/bin 目录下
这里的文件多少位(×64或×86)是根据自己的电脑来的
完成以上操作word才能正常转换为pdf文件
六、最后就是进行测试了，我是用的是springboot框架，这里放出测试代码
@Overridepublic void contractPrintDetail(HttpServletRequest request, HttpServletResponse response, Map<String, Object> mapArgu) {//查询出来的数据Map<String,Object> map = contractPrintMapper.mySelect(mapArgu);WordUtils wordUtil = new WordUtils();Map<String, Object> params = new LinkedHashMap<String, Object>();List<String[]> testList = new ArrayList<String[]>();params.put("${DWMC}",map.get("DWMC"));params.put("${DWDZ}",map.get("DWDZ"));params.put("${FDDBR}",map.get("FDDBR"));params.put("${XM}",map.get("XM"));params.put("${XBMC}",map.get("XBMC"));params.put("${LXDH}",map.get("LXDH"));params.put("${JG}",map.get("JG"));params.put("${ZS}",map.get("ZS"));params.put("${SFZHM}",map.get("SFZHM"));params.put("${GWMC}",map.get("GWMC"));try{String path = CFunc.clobToString((Clob) map.get("HTMB"));String name = CFunc.ToString(map.get("XM")) + "_" + CFunc.ToString(map.get("HTLX"))+"合同.docx";String filename = URLEncoder.encode(name, "utf-8");response.setContentType(request.getServletContext().getMimeType(filename));wordUtil.getWord(path, params, testList, filename, response);}catch (Exception e){e.printStackTrace();}
七、最后生成的pdf文档
