一次提交多个Command无法获取结果

        CreateNoteCommand createNoteCommand = new CreateNoteCommand(noteId, title);
        AsyncTaskResult<CommandResult> asyncTaskResult = commandService.executeAsync(createNoteCommand, CommandReturnType.EventHandled).join();
        Assert.notNull(asyncTaskResult, "asyncTaskResult");
        commandService.executeAsync(createNoteCommand, CommandReturnType.EventHandled).join();
        commandService.executeAsync(createNoteCommand, CommandReturnType.EventHandled).join();
        commandService.executeAsync(createNoteCommand, CommandReturnType.EventHandled).join();
        commandService.executeAsync(createNoteCommand, CommandReturnType.EventHandled).join();
        ChangeNoteTitleCommand titleCommand = new ChangeNoteTitleCommand(noteId, title + " change");
        // always block here
        Task.get(commandService.executeAsync(titleCommand, CommandReturnType.EventHandled));

这个执行语句会一直阻塞，获取不到future的结果

聚合根需要有构造参数，reset mailbox 需要改为同步执行

阻塞的原因是因为使用了Future.get()等待一个不能完成的任务，在使用Socket发送命令结果时可能会出现异常导致一直阻塞优化思路：将CommandResultProcessor的commandTaskDict优化成一个固定时间过期的Map，默认5s
