【SpringBoot】el-upload给后台传参，后台接受参数

首先el-upload给后台传参是以json的格式，如：

<el-upload
    ref="upload"
    class="upload-demo"
    action="/plan/test"
    :data="{test: 1}"
    :before-remove="beforeRemove"
    :limit="1"
    :on-exceed="handleExceed"
    accept=".xlsx,.xls"
    :file-list="confirmList"
>
</el-upload>

后台controller层接受参数格式为:

@RequestMapping("/test")
public void test(@RequestParam(value="test",required=false) int test,@RequestParam("file") MultipartFile file){
    System.out.println(test);
}

结果：
