person类
namespace DIDynamicConstructorParams.TestDI
{public class Person{public string Name { get; set; }public int Age { get; set; }private ILoggerPerson _loggerFactory;public Person(string name,int age, ILoggerPerson loggerFactory){Name name;Age age;_loggerFactory loggerFactory;}public string SayHello(){_loggerFactory.LogInformation(just a test);return $hello {Name},my age is {Age};}}
}
构造person的接口
namespace DIDynamicConstructorParams.TestDI
{public interface DIPersonFactory{Person CreatePerson(string name,int age, ILoggerPerson logger);}
}
接口实现
namespace DIDynamicConstructorParams.TestDI
{public class DI : DIPersonFactory{public Person CreatePerson(string name, int age,ILoggerPerson logger){return new Person(name, age,logger);}}
}
注册
builder.Services.AddScopedDIPersonFactory,DI();依赖注入生成person类
using DIDynamicConstructorParams.TestDI;
using Microsoft.AspNetCore.Mvc;// For more information on enabling Web API for empty projects, visit https://go.microsoft.com/fwlink/?LinkID397860namespace DIDynamicConstructorParams.Controllers
{[Route(api/[controller]/[action])][ApiController]public class DIController : ControllerBase{private readonly DIPersonFactory _dIPersonFactory;private ILoggerPerson _loggerFactory;public DIController(DIPersonFactory dIPersonFactory, ILoggerPerson loggerFactory){_dIPersonFactory dIPersonFactory;_loggerFactory loggerFactory;}[HttpGet]public string Test([FromQuery] string Name, [FromQuery] int Age){Person person _dIPersonFactory.CreatePerson(Name, Age,_loggerFactory);return person.SayHello();}}
