# LINGYUN.Abp.DistributedLocking.Dapr |
||||
|
|
||||
|
Abp分布式锁的Dapr实现 |
||||
|
|
||||
|
See: https://docs.dapr.io/developing-applications/building-blocks/distributed-lock/distributed-lock-api-overview/ |
||||
|
|
||||
|
## 配置使用 |
||||
|
|
||||
|
模块按需引用 |
||||
|
|
||||
|
```csharp |
||||
|
[DependsOn(typeof(AbpDistributedLockingDaprModule))] |
||||
|
public class YouProjectModule : AbpModule |
||||
|
{ |
||||
|
public override void ConfigureServices(ServiceConfigurationContext context) |
||||
|
{ |
||||
|
Configure<AbpDistributedLockingDaprOptions>(options => |
||||
|
{ |
||||
|
options.StoreName = "store-name"; |
||||
|
options.ResourceId = "resource-id"; |
||||
|
options.DefaultTimeout = TimeSpan.FromSeconds(30); |
||||
|
}); |
||||
|
} |
||||
|
} |
||||
|
``` |
||||
|
|
||||
|
## 配置说明 |
||||
|
|
||||
|
* AbpDistributedLockingDaprOptions.StoreName 在dapr component文件中定义的metadata name,默认: lockstore; |
||||
|
* AbpDistributedLockingDaprOptions.ResourceId 自定义一个资源名称,用于向dapr提供锁定的标识,默认: dapr-lock-id; |
||||
|
* AbpDistributedLockingDaprOptions.DefaultTimeout 默认锁定超时时间,默认: 30s. |
