今天在做java导出excel文件的时候，文件正常下载，但控制台报错，报错信息如下：

通过在网上查找相关资料后，最终解决了问题。这个错误产生的原因主要应该是后台返回的信息与前台接收的信息类型不一致，原代码如下：

```java
 @RequestMapping("/exportInProArchivesFiles")
    public  R  exportInProArchivesFiles(@RequestBody InProArchivesDTO dto, HttpServletResponse response) {
        inProArchivesService.exportInProArchivesFiles(dto, response);
        return R.data("导出成功");
    }

我在返回流信息到前台的同时又return了导出成功的信息，修改方法为 void 就解决了问题，修改后代码如下：

@RequestMapping("/exportInProArchivesFiles")
    public void exportInProArchivesFiles(@RequestBody InProArchivesDTO dto, HttpServletResponse response) {
        inProArchivesService.exportInProArchivesFiles(dto, response);
    }

只返回文件流信息就可以了。
