java导出world文档 poi-tl开源框架使用demo

一、准备
添加依赖

 
      com.deepoove
      >poi-tl
      1.7.3
 

定义模板
注意：需要把模板放在springboot项目的resources目录下，我这边放在了resources/template下

说明：
{{googslist}}这个是用来渲染动态表格标记点，定义这个后，才能在指定位置渲染
二、后台代码

@Controller
public class Test {

    @GetMapping("downloadWorld")
    public void downloadWorld(HttpServletResponse response,String hiddenDangerId){
        Map data = new HashMap<>();
        data.put("center","这个是简单描述内容");
        //创建表格数据
        List> goodsList = new ArrayList<>();
        Map d1 = new HashMap();
        d1.put("name","手机");
        d1.put("googsNum","10");
        goodsList.add(d1);
        //渲染表格
        HackLoopTableRenderPolicy policy = new HackLoopTableRenderPolicy();
        //注意goodslist就是表格上定义的goodslist
        Configure config = Configure.newBuilder().bind("goodslist", policy).build();
        data.put("goodslist",goodsList);
                //本地测试这样写
//        ClassPathResource classPathResource = new ClassPathResource("/template/test.docx");
//        String path = classPathResource.getURL().getPath();
//        XWPFTemplate template = XWPFTemplate.compile(path,config).render(data);
        //渲染数据  
        //这种写法支持打包成jar在linux服务器中使用能解决掉文件获取不到的问题
        XWPFTemplate template = XWPFTemplate.compile(WordUtil.class.getClassLoader().getResourceAsStream("template/test.docx"),config).render(data);
        downloadServlet(template,response);
    }

    private static void downloadServlet(XWPFTemplate template, HttpServletResponse response){
        try{
            response.setHeader("Content-disposition", "attachment;filename=" + new String("model".getBytes("gb2312"), "ISO8859-1") + ".docx");
            response.setCharacterEncoding("utf-8");
            response.setContentType("application/octet-stream");
            response.setContentType("multipart/form-data;charset=UTF-8");
            ServletOutputStream out = response.getOutputStream();
            template.write(out);
            out.flush();
            template.close();
            out.close();
        }catch (Exception e){
            e.getMessage();
        }
    }
}
