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
