4.基础设施层构建

EntityFramewrokCore 层构建
1.创建EntityFrameworkCore项目

2.引用
Volo.Abp.AspNetCore //ABP核心
Volo.Abp.EntityFrameworkCore //EFCore支持性

3.创建Module文件
继承AbpModule,依赖AbpEntityFrameworkCoreModule

 [DependsOn(typeof(Volo.Abp.EntityFrameworkCore.AbpEntityFrameworkCoreModule))]
 public class  AbpEntityFrameworkCoreModule:AbpModule
 {
 }

4.创建数据库Context上下文类继承AbpDbContext

 public class AbpEntityDBContext : AbpDbContext<AbpEntityDBContext>
 {
     public AbpEntityDBContext(DbContextOptions<AbpEntityDBContext> options) : base(options)
     {
     }
     protected override void OnModelCreating(ModelBuilder modelBuilder)
     {
         base.OnModelCreating(modelBuilder);
     }
 }

5.EntityFramewrokCore模块里面注入DbContext

   [DependsOn(typeof(Volo.Abp.EntityFrameworkCore.AbpEntityFrameworkCoreModule))]
   public class  AbpEntityFrameworkCoreModule:AbpModule
   {
       public override void ConfigureServices(ServiceConfigurationContext context)
       {
           //注入DB
           context.Services.AddAbpDbContext<AbpEntityDBContext>();
           //使用sqlserver数据库
           Configure<AbpDbContextOptions>(opt => opt.UseSqlServer());
       }
   }

6.在Web主程序appsettings.json里面配置连接字符串
7.在数据库上下文类加入特性
[ConnectionStringName("Default")]
完成连接字符串配置

8.配置主模块加入依赖

    typeof(AbpDemoEntityFrameworkCoreModule)
