SpringBoot下载Excel文件，解决文件损坏问题

public void downloadExcel(HttpServletResponse response) {
    InputStream bis = null;
    BufferedOutputStream out = null;

    try {
        String fileName = "批量新增模板.xlsx";
        fileName = URLEncoder.encode(fileName, "UTF-8");
        response.addHeader("Content-Disposition", "attachment;filename=" + fileName);
        response.setContentType("multipart/form-data");

        bis = new ClassPathResource("/template/template.xlsx").getInputStream();
        out = new BufferedOutputStream(response.getOutputStream());

        int len;
        while ((len = bis.read()) != -1) {
            out.write(len);
            out.flush();
        }
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    } finally {
        if (bis != null) {
            try {
                bis.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
        if (out != null) {
            try {
                out.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
}
           

 解决：pom文件中加入如下这个插件可以避免xlsx文件在resource目录下被自动压缩

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <version>2.6</version>
    <artifactId>maven-resources-plugin</artifactId>
    <configuration>
        <encoding>UTF-8</encoding>
        <nonFilteredFileExtensions>
            <nonFilteredFileExtension>xlsx</nonFilteredFileExtension>
        </nonFilteredFileExtensions>
    </configuration>
</plugin>
