swagger里面查看输出的流文件是乱码,怎么解决

很简单,在请求地址中加个参数produces = "application/octet-stream",以流的形式输出

@ApiOperation(value = "导出用户excel")
@GetMapping(value="/exportUser",produces = "application/octet-stream")
public void exportUser(HttpServletResponse response, UserDTO userDTO){
   userService.exportUser(response,userDTO,"用户列表");
}

然后就会出现下面这个下载文件的链接
