Upload files to server or local

Controller layer: Note (the return value is encapsulated by myself, you can change it according to your needs)

 //上传文件到文件服务器并且指定到位置
    @RequestMapping(value = "/uploads",method = {RequestMethod.POST,RequestMethod.GET})
    //Java后台设置全局跨域
    @CrossOrigin(origins    = "*", allowCredentials = "true",allowedHeaders = "",methods = {})
    public RestResult uploadFile(@RequestParam("file")MultipartFile file) throws IOException {
        if(file !=null){
            return complaintService.upload(file);
        }
        return new RestResultBuilder().error("文件不存在!");
    }

Service layer code:

 public RestResult upload(MultipartFile file) throws IOException {
        //获取文件名
        String fileName = file.getOriginalFilename();
        System.out.println("文件名为"+fileName);
        //获取文件的后缀名
        String suffixName = fileName.substring(fileName.lastIndexOf("."));
        System.out.println("后缀名为"+suffixName);
        //解决中文问题,linux下中文路径,图片显示问题
        fileName = UUID.randomUUID().toString().replace("-", "") + suffixName;
        //返回客户端文件路径图片显示问题
        String url = "http://ip:port/项目名"+"/upload/"+fileName;
        //String url = "localhost:8090"+"/upload/" + fileName;
        System.out.println("服务器返回的路径"+url);
        File dest = new File(ApiConstant.UPLOAD_PATH + fileName);
        System.out.println("目录为"+dest);
        // 检测是否存在目录
        if (!dest.getParentFile().exists()) {
            dest.getParentFile().mkdirs();
        }

        file.transferTo(dest);
        return new RestResultBuilder().setCode(0).setMsg("长传成功").setData(url).build();
    }

Tools

public class ApiConstant {

    // Header 中 token 的 key
    public final static String AUTHORIZATION = "***********";

    // JWTUtil Redis 数据库 用户 key 前缀
    public static String USER_JWT_PREFIX = "********";

    // Header 中 sign 的 key
    public static final String HEADER_ENCRYPTE_SIGN = "***********";

    // 该项目签名 sign-key
    public static final String SIGN_KEY = "******************";
	//上面没有可以不配置
    /**
     * 文件上传路径填自己路径
     */
    public static final String UPLOAD_PATH = "/home/file/";
    /**
     * 放在Tomcat的同一目录路径下
     */
    public static final String PRO_UPLOAD_PATH = "/home/ggj/soft/upload/";
	//本地路径
    public static final String DEV_UPLOAD_PATH = "D:/upload/";

Configuration class

@Configuration
public class uploadConfig implements WebMvcConfigurer {
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/upload/**").addResourceLocations("file:/home/file/");
        //registry.addResourceHandler("/upload/**").addResourceLocations("file:D:/upload/");

    }

So far: the file upload is no problem! First test whether the local can upload, and then package the upload server to try whether the server can upload!
