主要两个步骤:

1.注册服务 

builder.Services.AddScoped<ITestServiceA, TestServieceA>();

2.使用

app.MapGet("TestServiceAShowA",([FromServices] ITestServiceA testServiceA) =>
{
return testServiceA.ShowA();
});

 

案例Demo

1.项目结构

 

 2.MinimalApi.Interfaces代码

namespace MininalApi.Interfaces
{
    public interface ITestServiceA
    {
        public string ShowA();
    }
}
namespace MininalApi.Interfaces
{
    public interface ITestServiceB
    {
        public string ShowB();
    }
}

 3.MinimalApi.Services代码

using MininalApi.Interfaces;

namespace MininalApi.Services
{
    public class TestServieceA : ITestServiceA
    {
        public TestServieceA()
        {
            Console.WriteLine($"{GetType().Name}被构造");
        }
        public string ShowA()
        {
            return $"This is from {GetType().FullName} ShowA";
        }
    }
}
using MininalApi.Interfaces;

namespace MininalApi.Services
{
    public class TestServieceB : ITestServiceB
    {
        public ITestServiceA _testServiceA;
        public TestServieceB(ITestServiceA testServiceA)
        {
            _testServiceA = testServiceA;
            Console.WriteLine($"{GetType().Name}被构造");
        }
        public string ShowB()
        {
            return $"This is from {GetType().FullName} ShowB 调用 {_testServiceA.ShowA()}";
        }
    }
}

4.MinimalApi.Demo1的Program.cs代码

using Microsoft.AspNetCore.Mvc;
using MininalApi.Demo1;
using MininalApi.Interfaces;
using MininalApi.Services;

WebApplicationBuilder builder = WebApplication.CreateBuilder(args);
builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen();
builder.Services.AddScoped<ITestServiceA, TestServieceA>();
builder.Services.AddScoped<ITestServiceB, TestServieceB>();
WebApplication app = builder.Build();
app.UseSwagger();
app.UseSwaggerUI();

#region IOC+DI FromServices来自于IOC容器
app.MapGet("TestServiceAShowA",([FromServices] ITestServiceA testServiceA) =>
{
    return testServiceA.ShowA();
});

app.MapGet("TestServiceBShowB", ([FromServices] ITestServiceB testServiceB) =>
{
    return testServiceB.ShowB();
});
#endregion



app.Run();
