Dawning.Caching

缓存服务库，支持内存缓存和 Redis 分布式缓存。

安装

dotnet add package Dawning.Caching

功能特性

• ✅ 统一的缓存接口 ICacheService
• ✅ 内存缓存支持
• ✅ Redis 分布式缓存支持
• ✅ 可配置的过期时间
• ✅ 键前缀支持
• ✅ GetOrSet 模式

快速开始

内存缓存

builder.Services.AddDawningMemoryCache(options => { options.DefaultExpirationMinutes = 30; options.KeyPrefix = "myapp"; });

Redis 缓存

builder.Services.AddDawningRedisCache("localhost:6379", options => { options.DefaultExpirationMinutes = 60; options.KeyPrefix = "myapp"; options.Redis.InstanceName = "MyApp:"; });

使用缓存

public class UserService { private readonly ICacheService _cache; public UserService(ICacheService cache) { _cache = cache; } public async Task<User?> GetUserAsync(int id) { return await _cache.GetOrSetAsync( $"user:{id}", async () => await _userRepository.GetByIdAsync(id), TimeSpan.FromMinutes(10)); } public async Task InvalidateUserCacheAsync(int id) { await _cache.RemoveAsync($"user:{id}"); } }

配置选项

appsettings.json

{ "Caching": { "Provider": "Redis", "DefaultExpirationMinutes": 30, "KeyPrefix": "myapp", "Redis": { "ConnectionString": "localhost:6379", "InstanceName": "MyApp:", "Database": 0 } } }
