Entity framework core 扩展Identity Server 4的配置和操作数据上下文
我想定制Identity Server 4的配置和操作数据上下文 我只让您查看配置存储的代码,因为代码非常相似 这里是我的定制商店:Entity framework core 扩展Identity Server 4的配置和操作数据上下文,entity-framework-core,identityserver4,entity-framework-migrations,dbcontext,Entity Framework Core,Identityserver4,Entity Framework Migrations,Dbcontext,我想定制Identity Server 4的配置和操作数据上下文 我只让您查看配置存储的代码,因为代码非常相似 这里是我的定制商店: internal class MyConfigurationDbContext : ConfigurationDbContext { public MyConfigurationDbContext(DbContextOptions<ConfigurationDbContext> options, ConfigurationStoreOption
internal class MyConfigurationDbContext : ConfigurationDbContext
{
public MyConfigurationDbContext(DbContextOptions<ConfigurationDbContext> options, ConfigurationStoreOptions storeOptions)
: base(options, storeOptions)
{
}
protected override void OnModelCreating(ModelBuilder modelBuilder)
{
base.OnModelCreating(modelBuilder);
modelBuilder.HasDefaultSchema("configuration");
}
}
但在这种情况下,我得到了这个错误:
Unable to resolve service for type 'Microsoft.EntityFrameworkCore.DbContextOptions`1[IdentityServer4.EntityFramework.DbContexts.ConfigurationDbContext]' while attempting to activate 'My.IdentityServer.DataLayer.Repository.Contexts.MyConfigurationDbContext'.
我怎样才能解决它
谢谢正如您正确猜测的那样,您必须在上下文构造函数中使用
DbContextOptions
type for options参数
但为了能够调用基构造函数,而不是默认的非泛型构造函数,您应该使用上下文类型作为泛型类型参数从泛型继承上下文:
内部类MyConfigurationDbContext:ConfigurationDbContext
{
公共MyConfigurationDbContext(DbContextOptions选项、ConfigurationStoreOptions存储选项)
:base(选项、存储选项)
{
}
// ...
}
我是多么愚蠢。。。我没有想到我可以改变我的自定义上下文的继承。。。它起作用了
builder.AddConfigurationStore<MyConfigurationDbContext>(options =>
{
options.ConfigureDbContext = b => b.UseSqlServer(connectionString,
sql => sql.MigrationsAssembly(MIGRATION_ASSEMBLY));
});
