如何实例化LMAX Disruptor实现顺序处理（规避废弃构造器警告）

原代码中使用接收Executor参数的Disruptor构造方法已被废弃，会触发编译警告：

Disruptor(eventFactory, bufferSize, Executors.newSingleThreadExecutor())

等效替换方案 #

Executors.newSingleThreadExecutor()内部默认使用Executors.defaultThreadFactory()创建线程，因此直接改用该ThreadFactory即可实现完全等效的逻辑，同时消除警告：

Disruptor(eventFactory, bufferSize, Executors.defaultThreadFactory())

自定义线程配置（可选） #

如果需要对线程进行自定义配置（如设置线程名称、优先级等），可以手动实现ThreadFactory：

// 自定义ThreadFactory示例
ThreadFactory customThreadFactory = new ThreadFactory() {
    private final ThreadFactory defaultFactory = Executors.defaultThreadFactory();
    private int threadSeq = 0;

    @Override
    public Thread newThread(Runnable r) {
        Thread thread = defaultFactory.newThread(r);
        thread.setName("disruptor-worker-" + threadSeq++);
        thread.setPriority(Thread.NORM_PRIORITY);
        return thread;
    }
};

// 使用自定义ThreadFactory实例化Disruptor
Disruptor(eventFactory, bufferSize, customThreadFactory)
