问题分析：

因为发送此request请求的页面在该response进行数据写出的时候进行页面跳转更新为了新的页面，导致发送该request请求的页面被关闭，从而本次请求与响应结束，但是response此时还没有写完全部数据并输出到前台，当试图将数据输出到前端页面时，因为连接已经被关闭，导致此异常产生。

解决方案：

第一、增加全局异常拦截，并且判断异常名称，如果每次为

org.apache.catalina.connector.ClientAbortException，则返回null。
    if ("org.apache.catalina.connector.ClientAbortException".equals(ex.getClass().getName())) {
                log.error("发生clientAbortException");
                return null;
    }

第二、使用ResponseEntityExceptionHandler作为全局拦截方案

@ControllerAdvice
    @Slf4j
    public class RestResponseEntityExceptionHandler extends ResponseEntityExceptionHandler {
    
        @ExceptionHandler(Exception.class)
        protected ResponseEntity<String> handleExceptions(Exception ex, WebRequest request) {
            if ("org.apache.catalina.connector.ClientAbortException".equals(ex.getClass().getName())) {
                log.error("发生clientAbortException");
                return null;
            }
            HttpHeaders httpHeaders = new HttpHeaders();
            httpHeaders.set("Content-Type", "application/json;charset=UTF-8");
            return new ResponseEntity<String>(
                    "{\"code\":500,\"data\":null,\"msg\":\"服务器闹脾气，请稍后再试\"}", httpHeaders, HttpStatus.OK);
        }
    
    }
