Detailed explanation of using MicroService4Net to create a microservice instance

The term "Microservice Architecture (Microservice Architecture)" has been widely spread in the past few years. It is used to describe a special way of designing applications as a set of independent Deployed services. At present, this architectural approach has not been accurately defined, but it has certain common characteristics in the organization around business capabilities, automated deployment, intelligence in the endpoints, and decentralized control of language and data. .

"Microservices" - is just a new term in the software architecture that is flooding the streets. Although we despise such things very much, the software style described by this thing has attracted our attention more and more. Over the past few years, we've seen more and more projects using this style, so much so that colleagues around us take it for granted as the default form of development when building enterprise applications. Unfortunately, however, it is difficult to find theoretical descriptions of what the microservice style is and how it should be developed.

In short, the microservice architecture style is like developing a separate application as a set of small services. Each small service runs in its own process and communicates using lightweight mechanisms. , usually an HTTP API. These services are built around business capabilities and deployed independently through a fully automated deployment mechanism. These services are written in different programming languages, as well as using different data storage technologies, and maintain a minimum of centralized management.

In this article, I introduce Laowai's (MicroService4Net), which makes this class library very simple to create a microservice in a C# program.

You can choose one of the hosting methods: Windows service or console application.

Step one: Create a new console project, name it: MicroService4Net.Example, and then install MicroService4Net through the Nuget package manager

Step 2: Add namespace using MicroService4Net;

Add the following code in the Main method

static void Main(string[] args)
{var microService = new MicroService();
    microService.Run(args);
}

Default port: 8080. If you want to change the port, as follows

static void Main(string[] args)
{var microService = new MicroService(port: 8086);
    microService.Run(args);
}

　

Part 3: Add a new ApiController, such as ExampleController

using System.Web.Http; 
namespace MicroService4Net.Example.Controllers
{public class ExampleController : ApiController
    {
        [Route("Example")]public string GetExample()
        {return "Example";
        }
    }
}

Complete starting the console

Enter http://localhost:8086/Example:

in the browser. So far, we have simply created a small microservice like this. Let us learn more. of time is spent on business logic.

If you want the hosting to run on a "Windows Service" you need to add two empty classes

1 2	public class MicroServiceInstaller : ProjectInstaller { } public class MicroServiceService : InternalService { }

After regenerating the solution, the next step is much simpler. Open CMD as an administrator, use cd to switch to the directory where the project was compiled, and execute MicroService4Net.Example.exe -install (MicroService4Net.Example is the project name, replace it according to your own defined name). After the installation is successful, open the service management control The station will find the service we installed successfully.

If you want to uninstall the service, execute MicroService4Net.Example.exe -uninstall

and you’re done, as in If you need the source code, click
