一、概述
为了让接口程序更加模块化和可测试,采用依赖注入的方式调用接口方法。
二、安装Microsoft.Extensions.DependencyInjection
在NuGet里面搜索Microsoft.Extensions.DependencyInjection,并进行安装。
三、代码编写
3.1 创建Service 实现类
/**************************************功能:测试Service实现类*创 建 人:*********创建时间:2024-02-19* ***********************************/namespace Application{/// /// 测试Service./// public class TestService : ITestService{/// /// 测试查询./// public List<AgentGroup> TestSelect(){ var list = SqlSugarORM.SqlSugarHelper.Db.Queryable<AgentGroup>().ToList(); return list;}}}
3.2 创建Service 声明类
/**************************************功能:测试Service 接口类声明类*创 建 人:*********创建时间:2024-02-19* ***********************************/namespace CadApplication.Service{public interface ITestService{/// /// 测试查询./// List<AgentGroup> TestSelect();}}
3.3 控制器里面通过构造函数注入
/************************************* *功能:测试控制器 *创 建 人:******** *创建时间:2024-02-19 * ***********************************/namespace WebApi.Controllers{/// /// 测试Controller./// [ApiController][Route("[controller]")]public class TestController : ControllerBase{private readonly ITestService _testService;/// /// 构造函数./// /// public TestController(ITestService testService) {_testService=testService;}/// /// 测试查询./// [Route("TestSelect")][HttpPost]public List<AgentGroup> TestSelect() {return _testService.TestSelect();}}}
3.4 在启动类里面配置注入的Service
builder.Services.AddSingleton<ITestService, TestService>();
整体的Program.cs代码如下:
using Microsoft.AspNetCore.Hosting;using Microsoft.Extensions.DependencyInjection;var builder = WebApplication.CreateBuilder(args);// Add services to the container.builder.Services.AddControllers();// Learn more about configuring Swagger/OpenAPI at https://aka.ms/aspnetcore/swashbucklebuilder.Services.AddEndpointsApiExplorer();builder.Services.AddSwaggerGen();builder.Services.AddSingleton<ITestService, TestService>().AddSingleton<DrawLineService>();var app = builder.Build();// Configure the HTTP request pipeline.if (app.Environment.IsDevelopment()){app.UseSwagger();app.UseSwaggerUI();}app.UseAuthorization();app.MapControllers();app.Run();
四、结束
至此.net配置依赖注入结束。
