下载excel文件提示文件有不可识别内容

问题下载excel文件打开时提示有不可识别内容
下载Excel老是提示说有不可识别内容！然后去class文件查看文件并打开发现打开也提示有不可识别内容，而且文件大小也变了，说明变异的时候把excel文件也编译进去了。

    @GetMapping("/downLoadExcelFiles")
    public void downLoadExcelFiles(HttpServletResponse response, HttpServletRequest request) throws IOException {
        try (InputStream resourceAsStream = new ClassPathResource("/static/moban/test.xlsx").getInputStream()) {
            response.setContentType("application/force-download");

            response.setHeader("Content-disposition", "attachment;filename=" + "151515.xlsx");
            OutputStream outputStream = response.getOutputStream();
            int len = 0;
            byte[] buffer = new byte[1024 * 1024];
            while ((len = resourceAsStream.read(buffer)) > 0) {
                outputStream.write(buffer, 0, len);
            }
            outputStream.flush();
        } catch (Exception e) {
            log.error("下载失败：{}", e.getMessage());
        }
    }

解决办法：
不编译excel，在pom的过滤中加不编译excel文件

<resources>
			<resource>
				<directory>src/main/resources</directory>
				<filtering>false</filtering> //意识是不编译resources文件下的所有文件
				<includes>
					<include>**/*.xlsx</include>
				</includes>
			</resource>
		</resources>

<build>
		<finalName>kj-manager</finalName>
		<resources>
			<resource>
				<directory>src/main/resources</directory>
				<filtering>true</filtering>
				<excludes>
					<exclude>**/*.xlsx</exclude>
				</excludes>
			</resource>
