.net6 WebApi使用工厂模式+IOC

sqlsugar:

using SqlSugar;

namespace MyFanucApi.Service
{
    public interface ISqlSugarHelper
    {
        SqlSugarClient Db { get; }
    }
}

using MyFanucApi.Service.Sugar;
using SqlSugar;

            });

普通实体类:

按照泛型接口-抽象类-Impl实现

泛型接口:

namespace MyFanucApi.Service
{
    public interface IEntityService<T>
    {
        int InsertEntities(List<T> entities);

        int InsertEntity(T entity);

        int UpdateEntity(T entity);

        int DeleteEntity(int entityId);

        int DeleteEntities(List<T> entities);

        T QueryEntity(int entityId);

        List<T> QueryEntity();
    }
}

抽象类 :

using MyFanucApi.Entities.Menu;
using SqlSugar;

namespace MyFanucApi.Service.Common.Abs
{
    public abstract class AbsMenuItemNewService : IEntityService<MenuItemNew>
    {
        private readonly SqlSugarClient db;

        public AbsMenuItemNewService(SqlSugarClient db)
        {
            this.db = db;
        }
        public virtual int DeleteEntities(List<MenuItemNew> entities)
        {
            return db.Deleteable<MenuItemNew>(entities).ExecuteCommand();
        }

        public virtual int DeleteEntity(int entityId)

        public abstract List<MenuItemNew> QueryLevelOne();
        public abstract List<MenuItemNew> QueryLevelTwo();

        public virtual int InsertEntity(RolesItemNew entity)

        }

        public abstract RolesItemNew FindRolesItemNewById(int rolesItemNewId);

using MyFanucApi.Entities.Common;

Impl实现类要显式的调用父类(抽象类的)构造函数, 所以要写base(db). 因为db已经在子类中的构造函数中定义过了, 这时base 就不需要写参数类型了

using MyFanucApi.Entities.Menu;
using MyFanucApi.Service.Common.Abs;
using SqlSugar;

namespace MyFanucApi.Service.Common.Impl
{
    public class MenuItemNewServiceImpl : AbsMenuItemNewService
    {
        private readonly SqlSugarClient db;

        public MenuItemNewServiceImpl(SqlSugarClient db):base(db)
        {
            this.db = db;
        }
        public override List<MenuItemNew> QueryLevelOne()
        {
            return db.Queryable<MenuItemNew>().Where(x => x.level == 1).ToList();
        }

        public override List<MenuItemNew> QueryLevelThree()
        {
            return db.Queryable<MenuItemNew>().Where(x => x.level == 3).ToList();
        }

        public override List<MenuItemNew> QueryLevelTwo()
        {
            return db.Queryable<MenuItemNew>().Where(x => x.level == 2).ToList();
        }
    }
}

using MyFanucApi.Entities.Menu;
using MyFanucApi.Service.Common.Abs;
using SqlSugar;

        public RolesItemNewServiceImpl(SqlSugarClient db):base(db)
        {
            this.db = db;
        }

        public override RolesItemNew FindRolesItemNewById(int rolesItemNewId)
        {
            return db.Queryable<RolesItemNew>().Where(x => x.id == rolesItemNewId).First();
        }
    }
}

using MyFanucApi.Entities.Common;
using MyFanucApi.Service.Common.Abs;
using SqlSugar;

namespace MyFanucApi.Service.Common.Impl
{
    public class UserServiceImpl : AbstractUserService
    {
        private readonly SqlSugarClient db;

        public UserServiceImpl(SqlSugarClient db) : base(db)
        {
            this.db = db;
        }

        public override User FindUserByNameAndPwd(string? userName, string? password)
        {
            if (userName == null || password == null)
            {
                return new();
            }
            return db.Queryable<User>()
                .Where(x => x.UserName == userName
                && x.Password == password).First();
        }
    }
}
