创建实体
public sealed class User : Entity<long>, IAggregateRoot, IMayHaveCreator<long?>, IHasCreationTime, IHasModifierId<long?>, IHasModificationTime, IHasDeleterId<long?>, IHasDeletionTime
{
private User() { }
public User(string name, int age)
{
Name = name;
Age = age;
}
public string Name { get; private set; } = default!;
public int Age { get; }
/// <inheritdoc />
public DateTime CreationTime { get; set; }
/// <inheritdoc />
public long? DeleterId { get; set; }
/// <inheritdoc />
public DateTime? DeletionTime { get; set; }
/// <inheritdoc />
public DateTime? LastModificationTime { get; set; }
/// <inheritdoc />
public long? LastModifierId { get; set; }
/// <inheritdoc />
public long? CreatorId { get; set; }
public void ChangeName(string name)
{
Name = name;
}
}
1.Entity 实体需要什么类型Id请自己控制必须的。
2.IAggregateRoot 聚合根假如使用DDD模式的话,请加上这个,不是必须的请自己的需求来
3.IMayHaveCreator 创建人ID,可空的
4.IHasCreationTime 创建时间
5.IHasModifierId 修改人ID
6.IHasModificationTime 修改时间
7.IHasDeleterId 软删除用户ID
8.IHasDeletionTime、IHasSoftDelete 软删除时间,继承IHasSoftDelete,假如需要使用软删除的请就可以了。
以上1.是必须的,请按自己的需要
实体映射
public class UserConfiguration : IEntityTypeConfiguration<User>
{
/// <inheritdoc />
public void Configure(EntityTypeBuilder<User> builder)
{
builder.HasKey(o => o.Id);
builder.Property(o => o.Name).IsRequired().HasMaxLength(50);
builder.ToTable("User");
}
}
以上继承那些接口自动创建。
自动把IEntityTypeConfiguration实体映射器添加到OnModelCreating(ModelBuilder modelBuilder)模型生成器中。
EF 上下文
public sealed class TestDbContext : DefaultDbContext
{
public TestDbContext(DbContextOptions<TestDbContext> options, IServiceProvider? serviceProvider)
: base(options, serviceProvider)
{
Database.EnsureCreated(); //不是必须的,按自己方式,最好使用命令迁移
}
}
注册服务
AddEFCore<TestDbContext>(options => options.ConfigureDbContextBuilder = builder => { builder.UseSqlite("Data Source=My.db"); });
AddEFCore 方法里面,只注入工作单元,假如要使用仓储请自行注入
仓储使用
仓储有两种方式
1.
注入:
AddScoped(typeof(IRepository<,>), typeof(Repository<,>));
使用
_serviceProvider.GetService<IRepository<User, long>>();
最好在构造函数下
IRepository<User, long>
创建:
public interface IUserRepository : IRepository<User, long>;
/// <summary>
/// UserRepository
/// </summary>
/// <param name="dbContext"></param>
public class UserRepository(TestDbContext dbContext) : RepositoryBase<User, long, TestDbContext>(dbContext), IUserRepository;
注入:
AddScoped<IUserRepository, UserRepository>();
上下文工作单元
DefaultDbContext
必须继承
BeginTransactionAsync 异步开启事务 CommitTransactionAsync 异步提交当前事务 RollbackTransactionAsync 异步回滚事务 ApplyConfigurations 配置实体类型,可以重写 ConfigureBaseProperties 配置基本属性,添加 ConfigureByConvention、ConfigureSoftDelete DispatchSaveBeforeEventsAsync 异步调度发生前事件 GetUserId 得到当前用户 Id,保存时候赋值到那些继承的接口字段中,可以使用 AddCurrentUser()注入,也可以实现默认接口 ICurrentUser SetDeletedAudited 设置审计删除,IsDeleted、IHasDeletionTime,IHasDeleterId SetModifierAudited 设置审计修改,LastModificationTime、LastModifierId SetCreatorAudited 设置审计创建,CreationTime、IMayHaveCreator DeleteBefore 删除前操作 UpdateBefore 更新前删除 AddBefore 添加前操作 后面修改修改拦截器做 SaveChangesBeforeAsync 异步开始保存更改,自动实现审计接口属性赋值
