.Net Core CAP

cap 使用sqlserver 存储本地消息表
rabbitmq 消息发布/订阅

第一步：设置配置信息

        /// <summary>
        /// 添加cap
        /// </summary>
        /// <param name="services"></param>
        /// <param name="configuration"></param>
        public static void AddMyCap(this IServiceCollection services, IConfiguration configuration)
        {
            //保存本地消息记录库的 地址
            string capSql = configuration["CAP:connection"];

            //消息中间件
            string mqUrl = configuration["CAP:MQ:connection"];

            services.AddCap(x =>
            {
                x.UseSqlServer(options =>
                {
                    options.ConnectionString = capSql;
                });
                //x.UseRabbitMQ(mqUrl);
                x.UseRabbitMQ(options =>
                {
                    options.UserName = configuration["CAP:MQ:userName"];
                    options.HostName = mqUrl;
                    options.Password = configuration["CAP:MQ:password"];
                    options.Port = int.Parse(configuration["CAP:MQ:port"] ?? "5672");
                });
                //x.UseDashboard();

                //失败后的重试次数，默认50次；在FailedRetryInterval默认60秒的情况下，即默认重试50*60秒(50分钟)之后放弃失败重试
                x.FailedRetryCount = 10;

                //失败后的重拾间隔，默认60秒
                x.FailedRetryInterval = 60;
            });
        }

第二步：在StartUp 中的 ConfigService 中

  services.AddMyCap(Configuration);

然后就能使用了

使用例子：

 /// <summary>
    /// cap 测试
    /// </summary>
    [Route("api/[controller]")]
    [ApiController]
    public class CapController : ControllerBase
    {
        private readonly ICapPublisher _capPublisher;
        /// <summary>
        /// 
        /// </summary>
        /// <param name="capPublisher"></param>
        public CapController(ICapPublisher capPublisher)
        {
            _capPublisher = capPublisher;
        }
        /// <summary>
        /// 发布
        /// </summary>
        /// <returns></returns>
        [HttpGet,Route("publish")]
        public async Task<string> Publish()
        {
            await _capPublisher.PublishAsync("bim.core.api", DateTime.Now);
            return "发送成功";
        }
        /// <summary>
        /// 订阅
        /// </summary>
        /// <param name="date"></param>
        [SwaggerIgnore(true),HttpGet,Route("receive")]
        [CapSubscribe("bim.core.api")]
        public void Receive(string date)
        {
            Console.WriteLine($"接收到订阅:{date}");
        }
    }

订阅消息 如果是在 controller 中 只需要 贴上 CapSubscribe 特性 即可
如果是写在 service 层， 则 需要实现接口 ICapSubscribe
