<h2>报错原因：</h2>
之前上传文件部分代码如下
压缩上传可以普通上传在<code>file.transferTo(fie);</code>会报错 
因为上面创建临时文件的时候执行了<code>file.transferTo(temFile);</code>方法该方法执行一遍后文件流已经关闭
<pre class="prettyprint"><code class="prism language-java has-numbering"> //文件上传
 //创建临时文件将原文件file放入临时文件temFile
 File temFile =File.createTempFile("temp", "." + fileType);
 file.transferTo(temFile);
 if(temFile.length()>1024*1024*10){
 //大于10M 压缩上传
 String filedir = realDirectory+"/" + filename; // 以系统时间作为上传文件名称，设置上传文件的完整路径
 ImgUtill.compressImage(temFile.getAbsolutePath(), filedir);
 } else {
 //普通上传
 File fi = new File(realDirectory);
 try {
 if (!fi.isDirectory()) { // 如果文件夹不存在就新建
 fi.mkdirs();
 }
 File fie = new File(realDirectory, filename);
 file.transferTo(fie);
 } catch (IOException e) {
 e.printStackTrace();
 throw BusinessException.withErrorCode(ErrorConstant.Att.UPLOAD_FILE_FAIL)
 .withErrorMessageArguments(e.getMessage());
 }
 }
 temFile.deleteOnExit(); // 令临时文件在JVM关闭的时候自动删除
 temFile.delete(); // 立刻删除临时文件
<div class="hljs-button signin" data-title="登录后复制"></div></code></pre>
修改后的上传文件部分代码
<pre class="prettyprint"><code class="prism language-java has-numbering"> @PostMapping(value = "upload")
@ResponseBody
public APIResponse upload(@RequestParam("file") MultipartFile[] files,
 HttpServletRequest request,
 HttpServletResponse response) throws Exception{
<pre><code> //文件存在
if (files != null) {
 //遍历图片
 for (MultipartFile file : files) {
 //定义上传文件路径、文件名、文件格式
 java.util.Date Datenow=new java.util.Date();//获取当前日期
 java.text.SimpleDateFormat formatter = new java.text.SimpleDateFormat("yyyyMMdd");
 String nowdate = formatter.format(Datenow).substring(0,6); //将日期格式化
 //服务器真实路径
 String realDirectory = WebConst.FILE_REAL_PATH + nowdate;
 //原文件名
 String fileName = file.getOriginalFilename();
 //文件类型
 String fileType="";
 if (fileName.substring(fileName.length()-4).equals("jpeg")) {
 fileType=".jpeg";
 }else{
 fileType = fileName.substring(fileName.length()-3);
 }
 //对文件进行重新命名
 String filename = System.currentTimeMillis() + "." + fileType;

 //文件上传
 if(file.getSize()&gt;1024*1024*5){
 //大于10M 压缩上传
 //创建临时文件将原文件file放入临时文件temFile
 File temFile =File.createTempFile("temp", "." + fileType);
 file.transferTo(temFile);

 String filedir = realDirectory+"/" + filename; // 以系统时间作为上传文件名称，设置上传文件的完整路径
 ImgUtill.compressImage(temFile.getAbsolutePath(), filedir);

 temFile.deleteOnExit(); // 令临时文件在JVM关闭的时候自动删除
 temFile.delete(); // 立刻删除临时文件

 File fie = new File(realDirectory, filename);
 file.transferTo(fie);
 } catch (IOException e) {
 e.printStackTrace();
 throw BusinessException.withErrorCode(ErrorConstant.Att.UPLOAD_FILE_FAIL)
 .withErrorMessageArguments(e.getMessage());
 }
 }
 }
 return APIResponse.success();
} else {
 return APIResponse.fail("文件不存在");
}

}
</code></pre>
<div class="hljs-button signin" data-title="登录后复制"></div></code></pre>
这个时候普通上传依然报上面的错误
<h2>解决方法</h2>
上传路径使用绝对路径
修改常量类中定义的文件路径在 www 前加/
<pre class="prettyprint"><code class="prism language-java has-numbering"> //服务器真实地址(linux根目录需要以/开头)
public static String FILE_REAL_PATH = "/www/server/apache-tomcat-8.5.32/webapps/jxmstory/uploadfile/";
<div class="hljs-button signin" data-title="登录后复制"></div></code></pre>
未完
<pre><code> </div>
</code></pre>
