Example 1 with ServiceTooBusyException

use of pers.cy.iris.commons.exception.ServiceTooBusyException in project iris by chicc999.

the class DefaultDispatcherHandler method processResponse.

private void processResponse(final ChannelHandlerContext ctx, final Command command) {
    Header header = command.getHeader();
    // 超时被删除了
    final ResponseFuture responseFuture = futures.remove(header.getRequestId());
    if (responseFuture == null) {
        logger.info("ack type:" + header.getTypeString() + " requestId:" + header.getRequestId() + " but responseFuture is null");
        return;
    }
    responseFuture.setResponse(command);
    //回调交给线程池,避免回调任务阻塞IO线程
    try {
        serviceExecutor.submit(new Runnable() {

            @Override
            public void run() {
                responseFuture.done();
            }
        });
    } catch (RejectedExecutionException e) {
        //队列已满,拒绝执行回调
        responseFuture.cancel(new ServiceTooBusyException("请求成功,但没有足够的资源执行回调", e));

            // 如果没用指定处理该命令专用的线程池，则在普通业务线程池执行
            this.serviceExecutor.submit(task);
        } else {
