Asp.Net Core WebApi Swagger Autofac JWT的实现（一）
开发环境：VS2017、.Net core 2.1、SQLServer数据库
首先，先将项目的基础框架搭建起来，项目使用的是Core EF DBFirst机制，DDD模式
本章实现一下项目框架的基础搭建
1、使用 VS2017创建一个 .net core 的webapi项目，项目创建完成后，在项目中添加相关的业务类库，类库都为.net core 类库
NetCore.App：数据业务层
NetCore.Infrastructure：通用方法
NetCore.Repository：Model实体以及数据库
NetCore.WebApi：webapi 接口
2、NetCore.Repository的搭建
Nuget添加 Microsoft.EntityFrameworkCore.SqlServer、Z.EntityFramework.Plus.EFCore两个包的引用
Common：通用实体类
Domain：数据库表实体类
RequestEntity：WebApi请求参数实体类
ResponseEntity：WebApi返回数据实体类
NetCoreDbContext：数据库上下文
BaseRepository：数据库操作通用方法
UnitWork：数据库事务操作方法

在Domain下添加BaseModel和UserInfo实体类
using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.Text;
namespace NetCore.Repository.Domain
{
///
/// 通用字段实体类
///
public abstract class BaseModel
{
///
/// 主键
///
[Key]
public string ID { get; set; } = Guid.NewGuid().ToString();
///
/// 创建人
///
[Required,StringLength(50)]
public string CreateUser { get; set; }
///
/// 创建时间
///
public DateTime CreateTime { get; set; } = DateTime.Now;
///
/// 修改人
///
public string ModifyUser { get; set; }
///
/// 修改日期
///
public DateTime? ModifyTime { get; set; }
}
}
using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations.Schema;
using System.Text;
namespace NetCore.Repository.Domain
{
///
/// 用户信息表
///
[Table("UserInfo")]
public class UserInfo:BaseModel
{
///
/// 用户名
///
public string UserName { get; set; }
///
/// 登录名
///
public string LoginAccount { get; set; }
///
/// 登录密码
///
public string LoginPassword { get; set; }
}
}
在WebApi中的appsettings中配置数据库连接，添加ConnectionStrings
{
"Logging": {
"LogLevel": {
"Default": "Warning"
}
},
"AllowedHosts": "*",
"ConnectionStrings": {
"NetCoreDBContext": "Data Source=.;Initial Catalog=NetCoreWebApi;User=sa;Password=123456"
}
}在WebApi的Startup.cs中的ConfigureServices设置数据库的连接
services.AddDbContext(options => options.UseSqlServer(Configuration.GetConnectionString("NetCoreDBContext")));//获取数据库连接 3、NetCore.App的搭建
项目添加对NetCore.Repository及NetCore.Infrastructure两个项目的引用
在项目中添加BaseApp、UserInfoApp两个业务操作类
using System;
using System.Collections.Generic;
using System.Text;
using NetCore.Repository;
using NetCore.Repository.Domain;
namespace NetCore.App
{
public class BaseApp where T:BaseModel
{
protected UnitWork unitWork;
protected BaseRepository baseRepository;
public BaseApp(UnitWork _unitWork, BaseRepository _baseRepository)
{
unitWork = _unitWork;
baseRepository = _baseRepository;
}
}
}
using System;
using System.Collections.Generic;
using System.Text;
using System.Linq.Expressions;
using NetCore.Repository;
using NetCore.Repository.Domain;
using NetCore.Repository.RequestEntity;
using NetCore.Infrastructure;
namespace NetCore.App
{
///
/// 用户信息
///
public class UserInfoApp:BaseApp
{
public UserInfoApp(UnitWork unitWork,BaseRepository baseRepository):base(unitWork,baseRepository)
{
}
///
/// 新增
///
///
///
/// 判断账户是否已存在
///
///
///
///
/// 登录
///
/// 登录名
/// 登录密码
///
/// 获取用户信息
///
///
/// GetList( UserInfoRequest userInfoRequest)
{
Expression> predicte=x=>true;//查询条件
if (!string.IsNullOrEmpty(userInfoRequest.UserName))
{
predicte = predicte.And(x=>x.UserName.Contains(userInfoRequest.UserName));
}
Expression> predicteSort = x =>x.CreateTime;//排序字段
return baseRepository.GetList(predicteSort, predicte);
}
}
}
RequestEntity添加用户查询条件的实体
using System;
using System.Collections.Generic;
using System.Text;
namespace NetCore.Repository.RequestEntity
{
///
/// 用户查询信息
///
public class UserInfoRequest
{
///
/// 用户名
///
public string UserName { get; set; }
///
/// 登录名
///
public string LoginAccount { get; set; }
///
/// 登录密码
///
public string LoginPassword { get; set; }
}
}
