图片路径无法存储到数据库

其他数据都可以顺利存进去，只有图片路径存不进去。图片可以存进后台的文件夹中。也打印了上传的表格确认pictures里面有数据，请问是我哪里的代码有问题吗？下面都是我的后台代码，麻烦大家帮我看一下，谢谢

final static String PIC_PATH = "pictures/";

        @PostMapping("/api/uploadImage")
        public String uploadImage(MultipartHttpServletRequest multiRequest, HttpServletRequest request){
                System.out.println("上传图片");
                SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd"); //生成日期格式
                String datePrefix = dateFormat.format(new Date()); //生成当前日期作为前缀
                String savePath = "src/main/resources/" + PIC_PATH; // 存储路径

                File folder = new File(savePath+datePrefix); //生成带当前日期的文件路径

                if(!folder.isDirectory()){
                        folder.mkdirs();
                }

                String randomName = Objects.requireNonNull(multiRequest.getFile("pictures")).getOriginalFilename(); //获取图片名
                //生成随机数确保唯一性，并加上图片后缀
                assert randomName != null;
                String saveName = UUID.randomUUID().toString() + randomName.substring(randomName.lastIndexOf("."),randomName.length());
                String absolutePath = folder.getAbsolutePath(); //转换成绝对路径

                try {
                        File fileToSave = new File(absolutePath + File.separator + saveName);
                        Objects.requireNonNull(multiRequest.getFile("pictures")).transferTo(fileToSave); // 图片存储到服务端
                        String returnPath = request.getScheme() + "://" + request.getServerName()+":"+request.getServerPort() + "/pictures/" + datePrefix +"/"+ saveName;

                        return returnPath;

                }catch (Exception e){
                        e.printStackTrace();
                }
                return null;
        }

public int addIn(InStock inStock);

 "addIn">
        INSERT INTO instock
            (itemname,numbers,fromwho,worker,state,unit,pictures)
            VALUES
            (#{itemname},#{numbers},#{fromwho},#{worker},#{state},#{unit},#{pictures})
    

@RequestMapping("/addIn2")
    public String addIn2(@RequestBody InStock inStock){
        inStock.setState(0);
        inStock.setFromwho(2);
        int i = inStockDao.addIn(inStock);
        return i > 0 ? "success":"error";
    }

检查一下这几点看看
1、数据库表 instock 中的 pictures 列定义可能不正确，导致无法存储图片路径。要确保 pictures 列的数据类型和长度与存储图片路径的字符串匹配。
2、InStock 类中的 pictures 字段可能没有正确的设置 getter 和 setter 方法，导致无法正确读取和写入图片路径数据。检查 InStock 类中 pictures 字段的 getter 和 setter 方法是否正确定义。
3、在 addIn 方法中，插入数据库的 SQL 语句可能没有正确使用 #{pictures} 占位符，导致图片路径无法正确插入到数据库中。确保 SQL 语句中使用了 #{pictures} 占位符，并且在插入时将 InStock 对象的 getPictures() 方法的返回值作为参数传入。
