http11.Http11OutputBuffer.SocketOutputBuffer.doWrite

这是一个错误。
我在spring框架中，创建了一个基类SuperBaseController，
并且使用了@ModelAttribute
用来给HttpServletRequest和HttpServletResponse赋值
但是，在前台调取接口返回大量图片时，报错：http11.Http11OutputBuffer.SocketOutputBuffer.doWrite
之后，我就在接口上单独加上了HttpServletRequest和HttpServletResponse（这两个值不需要传递），就好了
我猜测是@ModelAttribute多次执行的问题。
SuperBaseController如下
public class SuperBaseController { protected HttpServletRequest request; protected HttpServletResponse response; @ModelAttribute public void setLang(HttpServletRequest request, HttpServletResponse response) { this.request = request; this.response = response; } }
接口如下：
@GetMapping(value = "downLitimg.do") public void downLitimg(String ArchiveDetailUUID,String YearMonth, HttpServletRequest request, HttpServletResponse response) { try { //获取Byte[] entity.getLitimgData()逻辑 //返回图片 BufferedImage image=ImageIO.read(new ByteArrayInputStream(entity.getLitimgData())); OutputStream out = response.getOutputStream(); ImageIO.write(image, "jpg", out); out.flush(); return; }else{ System.out.println("图片加载没有数据C，getLitimgData=null"+ArchiveDetailUUID); return; } } catch (IOException ex) { ex.printStackTrace(); return; } }
