之前做springboot项目中遇到文件上传到OSS云服务器,然后把文件路径返回给手机端。文件上传是java web中常见的操作，文件上传主要是将文件通过IO流传放到云服务器
一、请求controller，暴露接口请求
@RestController()
public class UpLoadController {
@PostMapping("/uploadImFile")
public ResponseEntity uploadImFile(
HttpServletRequest request,
@RequestParam(value = "file") MultipartFile file) {
return ResponseEntity.ok(userService.uploadImFile(request,file));}
}
二、service层，具体上传文件业务逻辑
@Override
public String uploadImFile(HttpServletRequest request, MultipartFile file) {
String result='';
try {
long fileSize = file.getSize();
if (fileSize > Long.parseLong(file_size)*1024*1024) {
return result;
}
String path = request.getSession().getServletContext().getRealPath("/");
String filename = file.getOriginalFilename();
String fileSuffix = filename.substring(filename.lastIndexOf(".") + 1, filename.length());
String fileNoSuffix = filename.substring(0, filename.lastIndexOf("."));
if (null != file) {
if (!"".equals(filename.trim())) {
File newFile = new File(path, filename);
FileOutputStream os = new FileOutputStream(newFile);
os.write(file.getBytes());
os.close();
file.transferTo(newFile);
String uploadUrl = null;
uploadUrl = AliyunOSSUtil.uploadImFile(newFile,fileType);
return uploadUrl;
}
}
} catch (Exception ex) {
ex.printStackTrace();
}
return result;
}
至此，文件已经成功上传到OSS云服务器了，其中uploadUrl就是OSS 返回的文件路径。(注：回头再把OSS服务代码贴出来。)
