C#RedLockNet实现REDIS操作锁解决业务并发问题
业务开发过程中经常会遇到并发的情况，或者多个业务接口会操作同一张表等需求，如果不处理的话就会导致重复触发的问题，比如对同一个库位进行操作，比如条码生成流水号等等。
简单使用
包RedLock.net
使用
初始化
var existingConnectionMultiplexer1 = ConnectionMultiplexer.Connect("127.0.0.1:6379");
var multiplexers = new List<RedLockMultiplexer>
{
existingConnectionMultiplexer1,
};
RedLockFactory = RedLockFactory.Create(multiplexers);
使用
var resource = "the-thing-we-are-locking-on";
var expiry = TimeSpan.FromSeconds(30);// 超时时间
var wait = TimeSpan.FromSeconds(10);//等待时间
var retry = TimeSpan.FromSeconds(1);//重试间隔
this.Invoke(() =>
{
if (from == "1")
textBox1.Text = $"{from}获取锁开始{DateTime.Now}";
else
textBox2.Text = $"{from}获取锁开始{DateTime.Now}";
});
// blocks until acquired or 'wait' timeout
await using (var redLock = await RedLockFactory.CreateLockAsync(resource, expiry, wait, retry)) // there are also non async Create() methods
{
// make sure we got the lock
if (redLock.IsAcquired)
{
// do stuff
}
this.Invoke(() =>
{
if (from == "1")
textBox1.Text = $"{from}获取锁{redLock.IsAcquired},{DateTime.Now}";
else
textBox2.Text = $"{from}获取锁{redLock.IsAcquired},{DateTime.Now}";
});
await Task.Delay(100);
}
redLock.IsAcquired 为true则获取到唯一锁可进行业务操作。
