这是我efcore的模块代码

[DependsOn(typeof(AbpEntityFrameworkCoreModule),
    typeof(AbpEntityFrameworkCoreMySQLModule))]
public class BlogEfCoreModule : AbpModule
{
    public override void ConfigureServices(ServiceConfigurationContext context)
    {
        var services = context.Services;
        Configure<AbpDbConnectionOptions>(opt =>
        {
            opt.ConnectionStrings.Default = context.Services.GetConfiguration().GetConnectionString("DefaultConnection");
        });

        services.AddAbpDbContext<BlogDbContext>(opt =>
        {
            opt.AddDefaultRepositories(true);
        });
    }
}
