如何在实体框架中持久化MassTransit状态数据？

// 定义状态数据的实体类
public class OrderStateEntity
{
    public int Id { get; set; }
    public Guid CorrelationId { get; set; }
    public string CurrentState { get; set; }
    // 其他属性
}

// 实体框架上下文类
public class AppDbContext : DbContext
{
    public DbSet<OrderStateEntity> OrderStates { get; set; }

    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        // 配置实体关系和映射规则
    }
}

// 创建数据库迁移
// dotnet ef migrations add InitialCreate

// MassTransit状态机
public class OrderStateMachine : MassTransitStateMachine<OrderState>
{
    public OrderStateMachine()
    {
        // 状态、事件和转换规则的定义
    }
}

// 配置状态数据持久化
public class MassTransitConfigurator
{
    public static IBusControl ConfigureBus(IServiceProvider serviceProvider)
    {
        var dbContext = serviceProvider.GetRequiredService<AppDbContext>();

        var repository = new EntityFrameworkStateMachineRepository<OrderState>(dbContext);
        var stateMachine = new OrderStateMachine();

        var busControl = Bus.Factory.CreateUsingInMemory(cfg =>
        {
            cfg.ReceiveEndpoint("order_state_machine", ep =>
            {
                ep.StateMachineSaga(stateMachine, repository);
            });
        });

        return busControl;
    }
}

// 在应用程序启动时配置MassTransit和实体框架
public class Startup
{
    public void ConfigureServices(IServiceCollection services)
    {
        // 配置实体框架
        services.AddDbContext<AppDbContext>(options =>
        {
            options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection"));
        });

        // 配置MassTransit
        services.AddMassTransit(x =>
        {
            x.AddBus(provider => MassTransitConfigurator.ConfigureBus(provider));
        });
    }

    public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
    {
        // 其他配置
    }
}
