1、新建一个word，里面填写内容，如：
2、导出wordjava类
/** * POI导出word测试 * @throws Exception */ @RequestMapping(value="exportApplyForm") public void exportApplyForm(HttpServletResponse response) throws Exception { Map<String, Object> params = new HashMap<String, Object>(); params.put("${name}", "1"); params.put("${sex}","1"); params.put("${political}", "1"); params.put("${place}", "1"); params.put("${classes}", "1"); params.put("${id}", "1"); params.put("${qq}", "1"); params.put("${tel}", "1"); params.put("${oldJob}", "1"); params.put("${swap}", "1"); params.put("${first}", "1"); params.put("${second}", "1"); params.put("${award}", "1"); params.put("${achievement}", "1"); params.put("${advice}", "1"); params.put("${attach}", "1"); XwpfTUtil xwpfTUtil = new XwpfTUtil(); XWPFDocument doc; String fileNameInResource = "sta.docx"; InputStream is; /*is = new FileInputStream(filePath);*/ is = getClass().getClassLoader().getResourceAsStream(fileNameInResource); //本身就在编译路径下。。。。 doc = new XWPFDocument(is); xwpfTUtil.replaceInPara(doc, params); //替换表格里面的变量 xwpfTUtil.replaceInTable(doc, params); OutputStream os = response.getOutputStream(); response.setContentType("application/vnd.ms-excel"); response.setHeader("Content-disposition","attachment;filename=测试.docx"); doc.write(os); xwpfTUtil.close(os); xwpfTUtil.close(is); os.flush(); os.close(); }
3、文件工具类

4、maven对应的jar包
<!--导入操作excel所需要的jar包--> <dependency> <groupId>org.apache.poi</groupId> <artifactId> poi</artifactId> <version>3.10-beta2</version> <type>jar</type> <scope>compile</scope> </dependency> <dependency> <groupId>org.apache.poi</groupId> <artifactId>poi-ooxml</artifactId> <version>3.10-beta2</version> <type>jar</type> </dependency> <dependency> <groupId>org.apache.poi</groupId> <artifactId>poi-ooxml-schemas</artifactId> <version>3.10-beta2</version> <type>jar</type> <scope>compile</scope> </dependency> <dependency> <groupId>org.apache.poi</groupId> <artifactId>poi-scratchpad</artifactId> <version>3.0.2-FINAL</version> </dependency>
