报错原因：

之前上传⽂件部分代码如下

压缩上传可以普通上传在ansferTo(fie)；会报错

因为上⾯创建临时⽂件的时候执⾏了ansferTo(temFile);⽅法该⽅法执⾏⼀遍后⽂件流已经关闭

//⽂件上传

//创建临时⽂件将原⽂件file放⼊临时⽂件temFile

File temFile = ateTempFile("temp", "." + fileType);

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

AbsolutePath(), 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);

} catch (IOException e) {

e.printStackTrace();

throw BusinessException.withErrorCode(ErrorConstant.Att.UPLOAD_FILE_FAIL)

.Message());

}

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

修改后的上传⽂件部分代码

@PostMapping(value = "upload")

@ResponseBody

public APIResponse upload(@RequestParam("file") MultipartFile[] files,

HttpServletRequest request,

HttpServletResponse response) throws Exception{

//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<spa java.text.SimpleDateFormat formatter = new = formatter.format(Date

now//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(fileNam fileType=".jpeg";

}else{

fileType = fileName.substring(fileName}

//对⽂件进⾏重新命名

String filename = System.currentTimeMillis(<span class="token punctua

//⽂件上传

if(file.getSize(//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("tem file.transferTo(temFile);

String filedir = realDirectory+"/" + filename;< ImgUtill.compressImage(temFile.ge

temFile.deleteOnExit(); temFile.delete<span class="token

punctuation">(); } else {

//普通上传

File fi = new File(realDirectory)</sp try {

if (!fi.isDirectory.mkdirs();

}

File fie = new File(realDirectory, file.transferTo(fie); } catch (IOException e) e.printStackTrace(); throw BusinessException.withErrorCode(ErrorConstant.withErrorMessageArguments(e.}

}

return APIResponse.success()< } else {

return APIResponse.fail("⽂件不存在" }

}

这个时候普通上传依然报上⾯的错误

解决⽅法

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 /

//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/";

未完
