ABP开发手记8 - 应用层创建应用服务

Posted 2022-12-15 it-evan

点这里进入ABP开发手记目录 

创建目录

在应用层(即JD.CRS.Application)下新建文件夹Course //用以存放Course相关应用服务

在JD.CRS.Application/Course下新建文件夹Dto //用以存放Course相关数据传输对象

创建数据传输对象

在JD.CRS.Application/Course/Dto下新建两个Dto

只读对象

CourseDto.cs //用于查询Course对象

贴上AutoMapFrom的特性

[AutoMapFrom(typeof(Entitys.Course))]

 1 using Abp.Application.Services.Dto;
 2 using Abp.AutoMapper;
 3 using System;
 4 using System.ComponentModel.DataAnnotations;

 6 namespace JD.CRS.Course.Dto

Class CourseDto

可写对象

CreateUpdateCourseDto //用于创建/修改Course对象

CreateUpdateCourseDto

创建应用服务接口

在JD.CRS.Application/Course下新建ICourseAppService.cs

 1 using Abp.Application.Services;
 2 using Abp.Application.Services.Dto;
 3 using JD.CRS.Course.Dto;
 4 
 5 namespace JD.CRS.Course
 6 
 7     public interface ICourseAppService : IAsyncCrudAppService<//定义了CRUD方法
 8              CourseDto, //用来展示课程
 9              int, //Course实体的主键
10              PagedResultRequestDto, //获取课程的时候用于分页
11              CreateUpdateCourseDto, //用于创建课程
12              CreateUpdateCourseDto> //用于更新课程
13     
14

ICourseAppService

创建应用服务

在JD.CRS.Application/Course下新建CourseAppService.cs 

 1 using Abp.Application.Services;
 2 using Abp.Application.Services.Dto;
 3 using Abp.Domain.Repositories;
 4 using JD.CRS.Course.Dto;
 5 using System.Threading.Tasks;
 6 
 7 namespace JD.CRS.Course

 9 
10     public class CourseAppService : AsyncCrudAppService<Entitys.Course, CourseDto, int, PagedResultRequestDto,
11                              CreateUpdateCourseDto, CreateUpdateCourseDto>, ICourseAppService
12 
13     
14 
15         public CourseAppService(IRepository<Entitys.Course, int> repository)

17         
18 
19

21         public override Task<CourseDto> Create(CreateUpdateCourseDto input)
22         
23             var sin = input;
24             return base.Create(input);
