基于 GitHub 开源项目

使用方法

// 使用MongoDB驱动创建一个链接
var setting = new MongoClientSettings
{
    Servers = new List<MongoServerAddress> { new("127.0.0.1", 27018) },
    Credential = MongoCredential.CreateCredential("admin", "guest", "guest"),
    LinqProvider = LinqProvider.V3
};
var client = new MongoClient(setting);
var db = client.GetDatabase("locks");
try
{
    // 由于使用到一些特性.需要将这个集合设置成 上限集合
    db.CreateCollection("release.signal", new()
    {
        // 这个数量理论上可以决定同时系统能有多少个锁.
        MaxDocuments = 100,
        MaxSize = 4096,
        Capped = true
    });
}
catch
{
    // ignored
}
IMongoCollection<LockAcquire> _locks = db.GetCollection<LockAcquire>("lock.acquire");
IMongoCollection<ReleaseSignal> _signals = db.GetCollection<ReleaseSignal>("release.signal");

// 获取锁
// 这里使用一个随机的ID作为锁ID,相当于其他锁中的Key.用来区分不同的业务的锁,也可以将不同的业务类型放到MongoDB中存起来,然后再使用的时候再取获取这个id
const string lockId = "64d44afde4473b85a177084c";

var mongoLock = DistributedLock.GenerateNew(_locks, _signals, ObjectId.Parse(lockId));
var acq = await mongoLock.AcquireAsync(TimeSpan.FromSeconds(5), TimeSpan.FromSeconds(0));

// 释放锁 也可以等超时释放
await mongoLock.ReleaseAsync(acq1);

实际用的时候大概是这样.

try
{
    if (acq.Acquired)
    {
        // 关键部分,它不能一次由任何服务器上的多个线程执行
        // ...
        // ...
    }
    else
    {
        // 超时!也许另一个线程没有释放锁...我们可以再试一次或抛出例外
    }
}
finally
{
    // 如果（acq.Acquired）无需手动操作
    await mongoLock.ReleaseAsync(acq);
}

注意事项和工作原理

当您尝试获取锁时,具有指定 lockId 的文档将添加到锁集合中,或者更新(如果存在).
释放锁时,将更新文档,并将新文档添加到信号上限集合中
当锁定正在等待时,将使用服务器端等待的可尾游标.详细信息
生存期是锁有效的时间段.在此时间之后,锁将自动“释放”,并且可以再次获取.它可以防止死锁.
不要使用长时间的超时,这可能会引发 MongoDB 驱动程序的异常.正常超时不超过 1-2 分钟!
