EFCore替换ID生成器

使用雪花ID：https://gitee.com/yitter/idgenerator

using SeleniumUtil
    /// <summary>
    /// 定义自己的ID生成器
    /// </summary>
    internal class CIDGenerator : ValueGenerator<long>
    {
        public IIdGenerator Generator { get; set; }
        public CIDGenerator(IConfiguration configuration)
        {
            var generatorId = configuration.GetValue<ushort>("IdGeneratorId");
            IdGeneratorOptions options = new IdGeneratorOptions(generatorId);
            Generator = new DefaultIdGenerator(options);
        }
        public override bool GeneratesTemporaryValues { get; }

        public override long Next(EntityEntry entry)
        {
            return Generator.NewLong();
        }
    }

FluentAPI 处使用 HasValueGenerator 方法替换默认生成

using SeleniumUtil
    /// <summary>
    /// FluentAPI 处使用 HasValueGenerator 替换
    /// </summary>
    /// <param name="builder"></param>
    protected override void OnModelCreating(ModelBuilder builder)
    {
        builder.Entity<Todo>(b =>
        {
            b.ToTable("t_todo");
            b.Property(p => p.Id)
                .HasColumnName("id")
                .HasComment("主键")
                .HasValueGenerator<CIDGenerator>()
                .ValueGeneratedOnAdd();
            b.Property(p => p.Content)
                .HasMaxLength(255)
                .HasColumnName("content")
                .HasComment("内容"); 
        });
    }
