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;
        }
    }
