我尝试使用identityserver 4和Asp.net身份和实体框架存储的示例。（请参见：https://github.com/IdentityServer/IdentityServer4.Samples/tree/release/Quickstarts/Combined_AspNetIdentity_and_EntityFrameworkStorage/src/IdentityServerWithAspIdAndEF） 我将SQL连接更改为MySql并运行示例。该示例创建了表格，但是，如果他想用数据填充表格，我会报错：

似乎id出了点问题。我该怎么解决这个问题？
我在startup.cd中更改了以下行：
services.AddDbContext<ApplicationDbContext>(options =>
options.UseMySql(connectionString));
.AddConfigurationStore(options =>
{
options.ConfigureDbContext = b =>
b.UseMySql(connectionString,
sql => sql.MigrationsAssembly(migrationsAssembly));
})
// this adds the operational data from DB (codes, tokens, consents)
.AddOperationalStore(options =>
{
options.ConfigureDbContext = b =>
b.UseMySql(connectionString,
sql => sql.MigrationsAssembly(migrationsAssembly));
// this enables automatic token cleanup. this is optional.
options.EnableTokenCleanup = true;
// options.TokenCleanupInterval = 15; // frequency in seconds to cleanup stale grants. 15 is useful during debugging
});
答案 0 :(得分：1)
问题在于 Id没有值。您无需插入Id的值（这很好），但是由于它是必填字段，并且未定义默认值，因此您会收到此消息。
原因是“ Id”列未设置为AUTO_INCREMENT。您可以通过调整migration model（目前在20180109200721_InitialIdentityServerConfigurationDbMigration.cs中）来解决此问题：
migrationBuilder.CreateTable(
name: "Clients",
columns: table => new
{
Id = table.Column<int>(nullable: false)
.Annotation("Sqlite:Autoincrement", true),
将注释行更改为：
.Annotation("MySql:ValueGenerationStrategy",
MySqlValueGenerationStrategy.IdentityColumn)
您将必须为all migration scripts中的所有表（具有自动增量）进行调整，请注意子目录中的脚本。全局替换可能会在这里为您提供帮助。
您可能要开始使用新的数据库来生成模型。请告诉我是否可以解决问题。
