使用Spring Boot和Thymeleaf创建文件下载链接

您需要将其更改

th:href

<a th:href="@{|/products/download?id=${product.id}|}"><span th:text="${product.name}"></span></a>

然后，您还需要更改控制器并包括

@ResponseBody

@RequestMapping(value="/products/download", method=RequestMethod.GET)@ResponseBodypublic FileSystemResource downloadFile(@Param(value="id") Long id) {    Product product = productRepo.findOne(id);    return new FileSystemResource(new File(product.getFileUrl()));}
