Laravel ShouldBeUnique 并不能让工作变得独一无二

Question

我预计标有ShouldBeUnique接口的作业不会被多次调度。然而，所有工作都像平常一样调度。

在我的 .env 文件中，redis 设置为用于队列连接以及缓存驱动程序：

QUEUE_CONNECTION=redis
CACHE_DRIVER=redis

我有两个正在运行的队列工作人员，它们竞争队列中的作业。

要推送作业，有控制台命令：

QUEUE_CONNECTION=redis
CACHE_DRIVER=redis

作业类如下所示（注意uniqueId是相同的）：

class TestUnique extends Command
{
    protected $signature = 'test:unique';
    protected $description = 'Command description';

    private Dispatcher $dispatcher;

    public function __construct(Dispatcher $dispatcher)
    {
        parent::__construct();
        $this->dispatcher = $dispatcher;
    }

    public function handle()
    {
        $this->dispatcher->dispatch(new SomeJob(1));
        $this->dispatcher->dispatch(new SomeJob(2));
        $this->dispatcher->dispatch(new SomeJob(3));
        $this->dispatcher->dispatch(new SomeJob(4));
        $this->dispatcher->dispatch(new SomeJob(5));

        return 0;
    }
}

一旦我们运行控制台命令来调度作业，所有这些作业都会像通常没有ShouldBeUnique. 日志：

这与缓存代码无关，因为服务定义使用queue:listen：

final class SomeJob implements ShouldQueue, ShouldBeUnique
{
    public function __construct(private int $id) { }

    public function handle(): void
    {
        var_dump("start handle $this->id");
        sleep(5);
        var_dump("finish handle $this->id");
    }

    public $uniqueFor = 3600;

    public function uniqueId()
    {
        return 1;
    }
}

谁能说出它的ShouldBeUnique用途以及当前代码有什么问题吗？
