+# LINGYUN.Abp.IdentityModel
+
+abp框架 **IIdentityModelAuthenticationService**接口缓存版本
+
+因官方**Volo.Abp.IdentityModel**模块没有对接口授权缓存,每次内部调用都会请求IDS服务器,会加重IDS服务器压力,
+创建使用缓存的接口实现
+
+## 配置使用
+
+模块按需引用，需要配置**Volo.Abp.IdentityModel**模块所需配置项
+
+
+```csharp
+[DependsOn(typeof(AbpCachedIdentityModelModule))]
+public class YouProjectModule : AbpModule
+{
+  // other
+}
+```
