AbpVnext使用分布式IDistributedCache缓存from Redis(带自定义扩展方法)
我的依赖包的主要版本以及Redis依赖如下
1：添加依赖
<PackageReference Include="Volo.Abp.Caching.StackExchangeRedis" Version="3.0.5" /> <ItemGroup>
<PackageReference Include="IdentityServer4.AccessTokenValidation" Version="3.0.1" />
<PackageReference Include="Microsoft.Extensions.PlatformAbstractions" Version="1.1.0" />
<PackageReference Include="Microsoft.VisualStudio.Azure.Containers.Tools.Targets" Version="1.9.5" />
<PackageReference Include="Serilog.Extensions.Hosting" Version="3.1.0" />
<PackageReference Include="Serilog.Sinks.Async" Version="1.4.0" />
<PackageReference Include="Serilog.Sinks.Console" Version="3.1.1" />
<PackageReference Include="Serilog.Sinks.Elasticsearch" Version="8.2.0" />
<PackageReference Include="Serilog.Sinks.File" Version="4.1.0" />
<PackageReference Include="SqlSugar.IOC" Version="1.4.0" />
<PackageReference Include="Swashbuckle.AspNetCore.SwaggerGen" Version="5.5.1" />
<PackageReference Include="Swashbuckle.AspNetCore.SwaggerUi" Version="5.5.1" />
<PackageReference Include="Volo.Abp.AspNetCore" Version="3.0.5" />

<PackageReference Include="Volo.Abp.Autofac" Version="3.0.5" />
<PackageReference Include="Volo.Abp.UI.Navigation" Version="3.0.5" />
//添加AbpVnext分布式redis缓存依赖包
<PackageReference Include="Volo.Abp.Caching.StackExchangeRedis" Version="3.0.5" />
</ItemGroup>
2：配置信息。默认在appsetting.json中配置即可,格式如下：
"Redis": { //Redis:Configuration
"IsEnabled": "true",
//该服务将会吧数据存储在DB7的数据库中
"Configuration": "171.74.78.153:6379,password=9966686@,defaultdatabase=7"
}
3：在hosting模块中添加依赖
using Volo.Abp.Caching.StackExchangeRedis; namespace GDBS.MonitoringService.HttpApi.Hosting
{
[DependsOn(
typeof(AbpAutofacModule),
typeof(AbpAspNetCoreMvcModule),
typeof(AbpAspNetCoreAuthenticationJwtBearerModule)
, typeof(IdentityEntityFrameworkCoreModule)
, typeof(MonitoringHttpApiModule)
, typeof(MonitoringApplicationContractsModule)
, typeof(SharedToolKitsModule)
, typeof(JketSharedDomainModule)
, typeof(AbpCachingStackExchangeRedisModule)//这里新增依赖模块
)]
public class MonitoringHttpApiHostingModule : AbpModule
{
public override void ConfigureServices(ServiceConfigurationContext context)
{
//测试时下面配置了还出不来，写入没有效果？？这里就直接在配置文件中处理了。
//service.AddStackExchangeRedisCache(redisoptions =>
//{
// redisoptions.Configuration = configuration["Redis:Configuration"];
// redisoptions.ConfigurationOptions = new StackExchange.Redis.ConfigurationOptions
// {
// ConnectTimeout = 10
// //EndPoints=new StackExchange.Redis.EndPointCollection { // //}
// };
//});
}
}
4：Controller中的主要代码
namespace GDBS.ProvincialLevelService.HttpApi.Controller
{
/// <summary>
/// ProvincialLevelService 省级服务
/// </summary>
[Authorize]
[Area("ProvincialLevelService")]
[Route("api/ProvincialLevelService/[Controller]")]
public class ProvincialLevelDataInfoController : AbpController
{
private readonly IBridgeTestDataService _service;
private readonly IBridgeTestDataService _service;
private readonly IHttpClientFactory _httpClientFactory;
private readonly IHttpContextAccessor _httpContext;
private readonly IFilesInfoService _filesInfoservice; /// <summary>
///
/// </summary>
/// <param name="service"></param>
/// <param name="httpClientFactory"></param>
/// <param name="httpContext"></param>
public ProvincialLevelDataInfoController(IBridgeTestDataService service, IHttpClientFactory httpClientFactory, IHttpContextAccessor httpContext, IFilesInfoService filesInfoservice)
{
_service = service;
_httpClientFactory = httpClientFactory;
_httpContext = httpContext;
_filesInfoservice = filesInfoservice;
} /// <summary>
/// TestRedisAddString
/// </summary>
/// <param name="key"></param>
/// <param name="redisvalue"></param>
/// <returns></returns>
[HttpGet("TestRedisAddString")]
[AllowAnonymous]
public async Task<OutputDto> TestRedisAddString(string key, string redisvalue)
{
try
{
await _service.DoTestRedis(key, redisvalue);
return OutputDto.ToResultSuccess(msg: "ok");
}
catch (Exception ex)
{
return OutputDto.ToResultFail(ex.Message);
}
}
}
}
5：Application中，通常我们在这里来注入分布式接口
using Microsoft.Extensions.Caching.Distributed;
namespace GDBS.ProvincialLevelService.Application.AppService
{
public class BridgeTestDataService : ApplicationService, IBridgeTestDataService
{
private readonly IDistributedCache _distributedCache;
public BridgeTestDataService(IDistributedCache distributedCache)
{
_distributedCache = distributedCache;
} public async Task<string> DoTestRedis(string key, string redisvalue)
{
try
{
await _distributedCache.SetStringAsync(key,redisvalue);
return "ok";
}
catch (Exception ex)
{
return $"错误{ex.Message}";
}
}
}
}
6：为了方便直接在Controller中注入测试，通常我们需要在Application中注入使用
/// <summary>
/// _cacheServer 通常我们在Application里面注册，这里只是测试
/// </summary>
private readonly IDistributedCache _cacheServer;
public ProvincialLevelDataInfoController(IDistributedCache cacheServer)
{
_cacheServer = cacheServer;
}
/// <summary>
/// TestRedisAddString
/// </summary>
/// <param name="key"></param>
/// <param name="redisvalue"></param>
/// <param name="ab_hd">true绝对过期,false:滑动过期</param>
/// <returns></returns>
[HttpGet("TestRedisAddString2")]
[AllowAnonymous]
public async Task<OutputDto> TestRedisAddString2(string key, string redisvalue, bool ab_hd = true)
{
try
{
await _cacheServer.SetStringAsync(key, redisvalue, RedisPolicyHelper.GetRedisProcily(ab_hd,60));
return OutputDto.ToResultSuccess(msg: "ok");
}
catch (Exception ex)
{
return OutputDto.ToResultFail(ex.Message);
}
}
7：分布式缓存的策略，使用绝对还是滑动过期，不使用策略就默认为长期保存，可以使用控制方法
using Microsoft.Extensions.Caching.Distributed;
using System;
namespace GDBS.Shared.ToolKits.Tool
{
public class RedisPolicyHelper
{
/// <summary>
/// 使用绝对还是滑动过期，不使用策略就默认为长期保存
/// </summary>
/// <param name="ab_hd">true绝对过期; false:滑动过期</param>
/// <param name="Seconds">默认60秒过期</param>
/// <returns></returns>
public static DistributedCacheEntryOptions GetRedisProcily(bool ab_hd, int Seconds = 60)
{
var policy = new DistributedCacheEntryOptions();
Seconds = Seconds <= 1 ? 60 : Seconds;
if (ab_hd)
policy.AbsoluteExpirationRelativeToNow = TimeSpan.FromSeconds(Seconds);
else
policy.SlidingExpiration = TimeSpan.FromSeconds(Seconds);
return policy;
}
}
}
8：自定义分布式缓存扩展方法
using System;
using System.Threading.Tasks;
using Newtonsoft.Json;
using Microsoft.Extensions.Caching.Distributed;
namespace GDBS.Shared.ToolKits
{
public static class RedisDistributeExtension
{
/// <summary>
/// 自定义IDistribute 分布式扩展方法 jason 同步方法
/// </summary>
/// <typeparam name="TModel"></typeparam>
/// <param name="cache"></param>
/// <param name="key"></param>
/// <param name="handler"></param>
/// <returns></returns>
public static TModel RedisGetOrCreate<TModel>(this IDistributedCache cache, string key, Func<DistributedCacheEntryOptions, TModel> handler)
{
TModel t;
string vs = cache.GetString(key);
if (string.IsNullOrEmpty(vs))
{
var options = new DistributedCacheEntryOptions();
t = handler.Invoke(options);
cache.SetString(key, JsonConvert.SerializeObject(t), options);
}
else
{
t = JsonConvert.DeserializeObject<TModel>(vs);
}
return t;
}
/// <summary>
/// 自定义IDistribute 分布式扩展方法 jason 异步方法
/// </summary>
/// <typeparam name="TModel"></typeparam>
/// <param name="cache"></param>
/// <param name="key"></param>
/// <param name="handler"></param>
/// <returns></returns>
public static async Task<TModel> RedisGetOrCreateAsync<TModel>(this IDistributedCache cache, string key, Func<DistributedCacheEntryOptions, Task<TModel>> handler)
{
TModel t;
var vs = await cache.GetStringAsync(key);
if (string.IsNullOrEmpty(vs))
{
var options = new DistributedCacheEntryOptions();
t = await handler.Invoke(options);
await cache.SetStringAsync(key, JsonConvert.SerializeObject(t), options);
}
else
{
t = JsonConvert.DeserializeObject<TModel>(vs);
}
return t;
}
}
}
9：测试自定义扩展方法，Controller中的主要code。
/// <summary>
/// 自定义分布式缓存的扩展方法,没有缓存就设置缓存，有就直接获取
/// </summary>
/// <param name="key"></param>
/// <param name="redisvalue"></param>
/// <param name="ab_hd"></param>
/// <returns></returns>
[HttpGet("TestRedisAddString3")]
[AllowAnonymous]
public async Task<OutputDto> TestRedisAddString3(string key, string redisvalue, bool ab_hd = true)
{
try
{
await _cacheServer.RedisGetOrCreateAsync<string>(key, (options) =>
{
options.AbsoluteExpiration = DateTimeOffset.Now.AddSeconds(30);
return Task.Factory.StartNew(() =>
{
return $"_cacheServer.RedisGetOrCreateAsync获取或者设置缓存的方法：{redisvalue},时间：{DateTime.Now}";
});
});
return OutputDto.ToResultSuccess(msg: "ok");
}
catch (Exception ex)
{
return OutputDto.ToResultFail(ex.Message);
}
}
10：调用自定义分布式扩展方法
11：测试结果部分主要截图：
12：公司一微服务系统中有多个服务，我们将不同的服务缓存数据将来存储在不同的Redis数据库中
好了今天就先到这里，下次有时间再更新，自学AbpVnext过程中难免会有一些bug或者不合理的地方,欢迎大家多多指教留言!!!
