一、数据库准备/日志安装

1.1 创建实体层

1. Entities

1. BaseEntity.cs

namespace ResumeManagement.Domain.Entities
{
    public abstract class BaseEntity
    {
        public Guid ID { get; set; }   
        public DateTime CreatedAt { get; set; } = DateTime.Now;
        public DateTime UpdateAt { get; set; } = DateTime.Now;
        public bool isActive { get; set; } = true;  
    }
}

2. Company.cs : 里面有Job的Collection

namespace ResumeManagement.Domain.Entities
{
    public class Company:BaseEntity
    {
        public string Name { get; set; }
        public CompanySize Size { get; set; }
        //relations 一对多
        public ICollection<Job> Jobs { get; set; }
    }
}

3. Job.cs:每个职位有对应的公司id和名称，一个职位有多个候选人

namespace ResumeManagement.Domain.Entities
{
    public class Job: BaseEntity
    {
        public string Title { get; set; }
        public JobLevel Level { get; set; }
        //relations 多对一
        public Guid CompanyID { get; set; }
        public Company Company { get; set; }
        //relations 一对多一个职位可以有多个候选人
        public ICollection<Candidate> Candidates { get; set; }
    }
}

4. Candidate.cs: 每个候选人，有投递的工作ID和工作名称

namespace ResumeManagement.Domain.Entities
{
    public class Candidate: BaseEntity
    {
        public string FirstName { get; set; }
        public string LastName { get; set; }
        public string Email { get; set; }
        public string Phone { get; set; }
        public string CoverLetter { get; set; }
        public string ResumeUrl { get; set; }
        //relations 多对一
        public Guid JobID { get; set; }
        public Job Job { get; set; }
    }
}

2. Enums 存放枚举

1. 公司规模的枚举

namespace ResumeManagement.Domain.Enums
{
    public enum CompanySize
    {
        Small,
        Medium,
        Large
    }
}

2.工作等级的

1.2 创建数据库层

1. 安装Persistance层需要的库

2. 创建ResumeDbContext

• 这里定义表的关系
  

3. 添加数据库配置/注册DBContext

1. API层数据库连接appsettings.json

{
  "Logging": {
    "LogLevel": {
      "Default": "Information",
      "Microsoft.AspNetCore": "Warning"
    }
  },
  "ConnectionStrings": {
    "ResumeDBConnectionStrings": "Server=.;Database=ResumeDB;Trusted_Connection=True;MultipleActiveResultSets=true;TrustServerCertificate=True;"
  },
  "AllowedHosts": "*"
}

2. 在Persistance层创建PersistanceRegistration.cs文件

using Microsoft.EntityFrameworkCore;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;

namespace ResumenManagement.Persistance
{
    public static class PersistanceRegistration
    {
        public static void  AddPersistanceRegistration(this IServiceCollection services, IConfiguration configuration)
        {
            services.AddDbContext<ResumeDbContext>(options =>
        options.UseSqlServer(configuration.GetConnectionString("ResumeDBConnectionStrings")));
        }
    }
}

3. 在Api层里注册

4. 执行Add-Migration

• 注意：如果从新添加了文件夹，一定要build项目之后，重启项目，才会执行migration成功
  
• 执行成功后，在数据里，就可以看到我们的表

5. 修改字段类型

• 在我们创建完成表之后，返现Size是int类型，Job里的Level也是int类型，这是因为枚举类型造成的原因，需要在DbContext里修改类型
• 

6. Enum支持Json

• 在Program.cs里添加

builder.Services.AddControllers().AddJsonOptions(options =>
{
    options.JsonSerializerOptions.Converters.Add(new JsonStringEnumConverter());
});

1.3 安装Serilog

1. Api层安装所需要的包

2. 在appsetting里配置

• 直接配置在setting之后，就不需要在中间件里配置

  "Serilog": {
    "MinimumLevel": {
      "Override": {
        "Microsoft": "Warning",
        "Microsoft.EntityFrameworkCore": "Information"
      }
    },
    "WriteTo": [
      {
        "Name": "Console",
        "Args": {
          "outputTemplate": "[{Timestamp:dd-MM HH:mm:ss} {Level:u3}] |{SourceContext}| {NewLine}{Message:lj}{NewLine}{Exception}"
        }
      },
      {
        "Name": "File",
        "Args": {
          "path": "Logs/Resturant-API-.log",
          "rollingInterval": "Day",
          "rollOnFileSizeLimit": true,
          "formatter": "Serilog.Formatting.Compact.CompactJsonFormatter, Serilog.Formatting.Compact"
        }
      }
    ]
  },
  "AllowedHosts": "*"

3. 注册Serilog在Program里

• 注册服务以及中间件
  

4.EfCore开启日志

• 在Persistence层里，efCore服务注册的地方PersistanceRegistration.cs

using Microsoft.EntityFrameworkCore;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Logging;
using ResumenManagement.Application.Contracts.Persistance;
using ResumenManagement.Persistance.Repositories;

namespace ResumenManagement.Persistance
{
    public static class PersistanceRegistration
    {
        public static void  AddPersistanceRegistration(this IServiceCollection services, IConfiguration configuration)
        {
            services.AddDbContext<ResumeDbContext>(options =>
                options.UseSqlServer(configuration.GetConnectionString("ResumeDBConnectionStrings"))
                .EnableSensitiveDataLogging() // 启用敏感数据记录
                );

            services.AddScoped(typeof(IAsyncRepository<>), typeof(BaseRepository<>));
            services.AddScoped<ICompanyRepository, CompanyRepository>();
        }
    }
}

5. 在Hanlder里使用

1. 需要先在Application层安装一个包才可以使用
   
2. 注册服务以及使用

二、Application层

2.1 安装MediaR和AutoMapper

1. 安装所需要的包和引用

2. 添加ApplicationRegistration

• 在Application层添加ApplicationRegistration.cs

using Microsoft.Extensions.DependencyInjection;

namespace ResumenManagement.Application
{
    public static class ApplicationRegistration
    {
        public static void AddApplicationRegistration(this IServiceCollection services)
        {
            //1.获取应用程序程序集
            var applicationAssembly = typeof(ApplicationRegistration).Assembly;

            //2.注册所有MediatR处理程序
            services.AddMediatR(cfg => cfg.RegisterServicesFromAssembly(applicationAssembly));
            //3.注册所有AutoMapper配置
            services.AddAutoMapper(applicationAssembly);              
        }
    }
}

3. 在Program里注册

• Program.cs里添加ApplicationRegistration
