java下载word - 技术栈

需要引入word模板的依赖，pom增加如下jar报包依赖

XML 复制代码

    <!--word模板-->
        <dependency>
            <groupId>com.deepoove</groupId>
            <artifactId>poi-tl</artifactId>
            <version>1.9.1</version>
        </dependency>

但测试的时候发现，word模板填充时报错

搜了各种资料，原来maven打包时把resource下的word模板压缩了，导致读取模板文件时失败了。

完整的word模板和下载程序如下：

java 复制代码

  @RequestMapping(value = "/downloadDocx", method = RequestMethod.GET)
    public void downloadDocx(HttpServletResponse response) {

        //根据业务查询数据，并组装模板中要替换的params，这里也可以使用guava工具类直接将java dto转换成map
        Map<String, Object> params = new HashMap<>();
try {

            //模板放在项目的 resource目录下的templates目录，模板里需要替换的变量使用EL表达式标识，比如 {{userName}}   在params中有个key为userName的
            ClassPathResource resource = new ClassPathResource("templates\\test.docx");
            XWPFTemplate template = renderTemplate(resource.getStream(), params);

            response.setContentType("application/octet-stream;charset=utf-8");
            response.setHeader("Content-Disposition", "attachment;filename=" + URLEncoder.encode("test", StandardCharsets.UTF_8.name()) + ".docx");
            try (OutputStream out = response.getOutputStream()) {
                template.writeAndClose(out);
            } catch (IOException e) {
                logger.error("io异常", e);
            }

        } catch (Exception e) {
            logger.error("下载docx异常", e);
        }

}


/**
     * 模板替换
     * @param templateInputStream
     * @param dataMap
     * @return
     */
private XWPFTemplate renderTemplate(InputStream templateInputStream, Map<String, Object> dataMap) {
        ConfigureBuilder configureBuilder = Configure.builder()
                .useSpringEL()  // 启用Spring EL表达式 模板中使用 {{}} {{userName}}
                .bind("dataTable", new HackLoopTableRenderPolicy());  // 设置循环策略
        Configure config = configureBuilder.build();
        return XWPFTemplate.compile(templateInputStream, config).render(dataMap);

    }
