Add ordering for MessageHandlers #10

Closed antonyvorontsov closed 4 years ago

antonyvorontsov commented 4 years ago

Add order for each MessageHandler in case if a client want to sub more than 1 message handler for one routing key (in other words when one message being processed by multiple message handlers).

I have done it here https://github.com/AntonyVorontsov/RabbitMQ.Client.Core.DependencyInjection/pull/24

So now message handlers can be registered with the given order like this

services.AddRabbitMqClient(clientConfiguration)
    .AddExchange("ExchangeName", isConsuming: true, exchangeConfiguration)
    .AddMessageHandlerSingleton<CustomMessageHandler>("first.routing.key", order: 20)
    .AddMessageHandlerSingleton<OtherCustomMessageHandler>("first.routing.key", order: 10)

Higher order means that higher importance of message handler. That means that in the given example CustomMessageHandler will handle received message first and the OtherCustomMessageHandler will be second.

Complete coverage of that feature will be added to the documentation file ASAP. The release version of the library that contains explained feature - v3.1.2
