从服务器读取图片并显示

@GetMapping("/onlineCheckCar/loading")
    public ResponseEntity loadingPicture(String imgUrl) {
        try {
            return ResponseEntity.ok(resourceLoader.getResource("file:" + imgUrl));
        } catch (Exception e) {
            e.printStackTrace();
            return ResponseEntity.notFound().build();
        }
    }

　　前端定义一个BaseUrl

baseUrl: "/api/v1.0/offlineOrder/onlineCheckCar/loading?imgUrl="

　　

 <img
              width="100%"
              :src="baseUrl+encodeURI(row.orderLicenseUrl)"
              v-if="row.orderLicenseUrl!=''&&row.orderLicenseUrl!=undefined"
            />
