基于.net EF6 MVC5+WEB Api 的Web系统框架总结（2）-业务项目搭建

本节将介绍如何进行业务项目搭建。

本业务项目示例是简单的企业信息管理功能，业务项目采用Code First方式，搭建包括：

1. 创建实体项目
2. 创建实体数据表映射
3. 创建业务处理项目
4. 创建业务Web项目

搭建完项目效果：

1、创建实体项目-ShiQuan.Company.Entity

创建企业信息实体

示例中企业信息包括：编号、名称、负责人、联系人、联系电话、联系地址等

using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ShiQuan.Company.Entity
{
    /// 

    /// 企业信息
    /// 
    public class CompanyInfoEntity:BasicCompanyEntity
    {
        /// 

        /// 编号
        /// 
        [Display(Name = "编号"), MaxLength(50)]
        public string Code { get; set; }
        /// 

        /// 编号
        /// 
        [Display(Name = "编号"), MaxLength(100)]
        public string Name { get; set; }
        /// 

        /// 负责人
        /// 
        [Display(Name = "负责人"), MaxLength(50)]
        public string Leader { get; set; }
        /// 

        /// 联系人
        /// 
        [Display(Name = "联系人"), MaxLength(50)]
        public string Linkman { get; set; }
        /// 

        /// 联系电话
        /// 
        [Display(Name = "联系电话"), MaxLength(50)]
        public string Phone { get; set; }
        /// 

        /// 联系地址
        /// 
        [Display(Name = "联系地址"), MaxLength(255)]
        public string Address { get; set; }
        /// 

        /// 备注说明
        /// 
        [Display(Name = "备注说明"), MaxLength(255)]
        public string Remark { get; set; }
    }
}

 

2、创建实体数据表映射项目-ShiQuan.Company.Mapping

创建空数据库

创建项目

创建企业信息数据表映射

using ShiQuan.Company.Entity;
using System;
using System.Collections.Generic;
using System.Data.Entity.ModelConfiguration;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ShiQuan.Company.Mapping
{
    /// 

    /// 实体数据映射
    /// 
    public class CompanyInfoMap : EntityTypeConfiguration
    {
        public CompanyInfoMap()
        {
            #region 表、主键
            //表
            this.ToTable("CompanyInfo");
            //主键
            this.HasKey(t => t.Id);
            #endregion

            #region 配置关系
            #endregion
        }
    }
}

创建实体数据库上下文

选择空Code First 模型

namespace ShiQuan.Company.Mapping
{
    using System;
    using System.Data.Entity;
    using System.Data.Entity.ModelConfiguration.Conventions;
    using System.Linq;

    public class CompanyDbContext : DbContext
    {
        //您的上下文已配置为从您的应用程序的配置文件(App.config 或 Web.config)
        //使用“CompanyDbContext”连接字符串。默认情况下，此连接字符串针对您的 LocalDb 实例上的
        //“ShiQuan.Company.Mapping.CompanyDbContext”数据库。
        // 
        //如果您想要针对其他数据库和/或数据库提供程序，请在应用程序配置文件中修改“CompanyDbContext”
        //连接字符串。
        public CompanyDbContext()
            : base("name=CompanyDbContext")
        {
        }

        //为您要在模型中包含的每种实体类型都添加 DbSet。有关配置和使用 Code First  模型
        //的详细信息，请参阅 http://go.microsoft.com/fwlink/?LinkId=390109。

        // public virtual DbSet MyEntities { get; set; }
        /// 

        /// 重写数据型号创建，添加企业信息数据表映射
        /// 
        /// 
        protected override void OnModelCreating(DbModelBuilder modelBuilder)
        {
            modelBuilder.Conventions.Remove();
            
            modelBuilder.Configurations.Add(new CompanyInfoMap());

            base.OnModelCreating(modelBuilder);
        }
    }
}

 

配置数据库连接

  <connectionStrings>
    <add name="CompanyDbContext" connectionString="Server=127.0.0.1;Initial Catalog=VSD_CompanyDB;User ID=sa;Password=123456*a" providerName="System.Data.SqlClient" />
  connectionStrings>

配置数据库上下文允许进行更新升级

using System;
using System.Collections.Generic;
using System.Data.Entity.Migrations;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ShiQuan.Company.Mapping.Migrations
{
    internal sealed class Configuration : DbMigrationsConfiguration
    {
        public Configuration()
        {
            //配置允许数据库更新升级
            AutomaticMigrationsEnabled = true;
            AutomaticMigrationDataLossAllowed = true;
        }

        protected override void Seed(CompanyDbContext dbContext)
        {
            
        }
    }
}

 

使用update-database 对数据库进行升级更新

 

3、创建企业信息管理业务处理项目-ShiQuan.Company.Business

创建企业信息库业务处理基础类，实现实体查询、删除和保存功能。

using Learun.DataBase.Repository;
using Learun.Util;
using ShiQuan.Company.Entity;
using System;
using System.Collections.Generic;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Linq.Expressions;
using System.Text;
using System.Threading.Tasks;

namespace ShiQuan.Company.Business
{
    /// 

    /// 企业信息管理库业务处理基础类
    /// 
    /// 
    public class BasicCompanyBLL : RepositoryFactory where T : class,new()
    {
        protected string dbConn = "";

        /// 

        /// 构造函数
        /// 
        public BasicCompanyBLL()
        {
            //this.dbConn = ConfigurationManager.ConnectionStrings["CompanyDbContext"].ConnectionString;
            this.dbConn = "CompanyDbContext";
        }
        #region 获取数据

        {

            expression = QueryStringToExpression(expression, queryJson);
            return this.BaseRepository(dbConn).FindList(expression, pagination);
        }
        ///
