上传图片获取上传路径

我想获取图片的上传路径，并在前端把上传路径传给addForm.pictures，可以麻烦大家帮我看一下，前后端的代码要怎么改吗？我现在返回的好像是图片的名字，并且数据库里面没有办法保存，是空白的

                  <el-col :span="8">
                    <el-form-item label="物资图片" prop="unit">
                      <el-upload
                          accept="image/jpeg,image/png"
                          :on-preview="handlePreview"
                          :on-remove="handleRemove"
                          :before-remove="beforeRemove"
                          ref="upload"
                          :action="'http://localhost:8989/api/uploadImage'"
                          :http-request="upload"
                          :auto-upload="false"
                          :before-upload="onBeforeUpload"
                          multiple
                          :limit="1"
                          :on-exceed="handleExceed"
                          v-model="addForm.pictures">
                        <el-button size="small" type="primary">点击上传el-button>
                        <div slot="tip" class="el-upload__tip">只能上传jpg/png文件，且不超过1M
                      el-upload>
                    el-form-item>
                  el-col>
                el-row>
 
                <el-form-item>
                  <el-button type="primary" @click="addIn">立即捐赠el-button>
                el-form-item>
 
 addIn() {
      this.$refs.upload.submit();
      this.$refs.addFormRef.validate(async valid => {
        if (!valid) return;
        const {data: res} = await this.$http.post("addIn2", this.addForm);
        if (res != "success") {
          return this.$message.error("捐赠失败~");
        }
        this.$message.success("捐赠成功~");
        this.addDialogVisible = false;
      });
    },
 
 
<insert id="addIn">
        INSERT INTO instock
            (itemname,numbers,fromwho,worker,state,unit,pictures)
            VALUE
            (#{itemname},#{numbers},#{fromwho},#{worker},#{state},#{unit},#{pictures})
    insert>
 
 
 @RequestMapping("/addIn2")
    public String addIn2(@RequestBody InStock inStock){
        inStock.setState(0);
        inStock.setFromwho(2);
        int i = inStockDao.addIn(inStock);
        return i > 0 ? "success":"error";
    }
 
 @RequestMapping(value = "/api/uploadImage", method = RequestMethod.POST)
    @ResponseBody
    public String uploadImage(@RequestParam("files") MultipartFile file) throws IOException {
        System.out.println(file.getOriginalFilename() + "图片已传入!!");
        byte[] b = file.getBytes();
        String fileName = file.getOriginalFilename();
        Path path = Paths.get("src/main/resources/pictures/" + fileName);
        Files.write(path, b);
        return fileName;
    }
 
 

你说的上传路径是什么，是浏览器端的客户端的文件路径？这个不是所有的浏览器都支持获取的
