abp小试牛刀之应用服务开发

应用服务使用简单的CRUD，实现方式基于CrudAppService方式

1.DTO编写

NewsItemDto.cs

using System;
using Volo.Abp.Application.Dtos;

namespace MyAbp.Application.Contracts.News.Dto
{
    public class NewsItemDto:EntityDto<Guid>
    {
        public string Title { get; set; }
        public string Short { get; set; }
        public string Full { get; set; }
        public bool Published { get; set; } = false;
        public DateTime? StartDateUtc { get; set; }
        public DateTime? EndDateUtc { get; set; }
        public bool AllowComments { get; set; } = false;
        public int OrderBy { get; set; }
    }
}

CreateNewsItemDto.cs

using System;
using System.ComponentModel.DataAnnotations;

namespace MyAbp.Application.Contracts.News.Dto
{
    public class CreateNewsItemDto
    {
        [Required]
        [StringLength(128)]
        public string Title { get; set; }
        [Required]
        public string Short { get; set; }
        [Required]
        public string Full { get; set; }
        public bool Published { get; set; } = false;
        [Required]
        public DateTime? StartDateUtc { get; set; }
        [Required]
        public DateTime? EndDateUtc { get; set; }
        public bool AllowComments { get; set; } = false;
        public int OrderBy { get; set; }
    }
}

UpdateNewsItemDto.cs

using System;
using System.ComponentModel.DataAnnotations;

namespace MyAbp.Application.Contracts.News.Dto
{
    public class UpdateNewsItemDto
    {
        [Required]
        [StringLength(128)]
        public string Title { get; set; }
        [Required]
        public string Short { get; set; }
        [Required]
        public string Full { get; set; }
        public bool Published { get; set; } = false;
        [Required]
        public DateTime? StartDateUtc { get; set; }
        [Required]
        public DateTime? EndDateUtc { get; set; }
        public bool AllowComments { get; set; } = false;
        public int OrderBy { get; set; }
    }
}

2.接口编写

using System;
using MyAbp.Application.Contracts.News.Dto;

using Volo.Abp.Application.Dtos;
using Volo.Abp.Application.Services;

namespace MyAbp.Application.Contracts.News
{
    public interface INewsItemAppService : ICrudAppService<NewsItemDto,
          Guid,
          PagedAndSortedResultRequestDto,
          CreateNewsItemDto,
          UpdateNewsItemDto>
    {
    }
}

3.服务代码编写

using System;
using Volo.Abp.Application.Dtos;
using Volo.Abp.Application.Services;
using Volo.Abp.Domain.Repositories;
using MyAbp.Domain.News;
using MyAbp.Application.Contracts.News.Dto;
using MyAbp.Application.Contracts.News;

namespace MyAbp.Application.News
{

    public class NewsItemAppService : CrudAppService<NewsItem, NewsItemDto, Guid, PagedAndSortedResultRequestDto,
           CreateNewsItemDto, UpdateNewsItemDto>,
       INewsItemAppService
    {
        public NewsItemAppService(IRepository<NewsItem, Guid> repository)
           : base(repository)
        {

        }
    }
}
