ClientBortException:java.io.IOException:管道破裂

我有以下代码在Grails中的outputstream上发送jpg图像。我在缓存头生成{…}语句中使用这个块

                            def imageByteArray = // some image byte []
            response.setContentType("image/jpeg")
            response.setHeader("Content-disposition", "filename=\"${imageName}${imageExtension}\"")
            response.setContentLength(imageByteArray.size())

            def outputStream = null
            try {
                outputStream = response.outputStream
                outputStream << imageByteArray
            } catch (IOException e){
                log.error('getImage() - Canceled download?', e)
            } finally {
                if (outputStream != null){
                    try {
                        outputStream.close()
                    } catch (IOException e) {
                        log.error('Exception on close', e)
                    }
                }
                return
            }

为了避免这个错误，我不知道要更改什么。我还尝试在outputstream上使用flush（），但没有成功。 怎么办

从错误日志中，我可以看到“取消下载”被抛出，因此我认为写操作出错了

尽量不要关闭response.outputStream。一般来说，如果你没有打开一个流，你就不应该关闭它。@AnujAneja我取消了下载异常，这是我应该担心的，还是我应该把它留下，不打印出来？所以问题是我应该处理这个异常吗？
