在ASP.NET Core 6中,可以使用租户特定容器来将多个租户的依赖项隔离开来。在这种设置中,每个租户都有自己的实例,可以具有不同的服务配置和不同的生命周期。
以下是使用ASP.NET Core 6中的租户特定容器的步骤:
public void ConfigureServices(IServiceCollection services)
{
// Add services to the global container.
services.AddMultitenancy();
services.AddScoped();
}
public void Configure(IApplicationBuilder app)
{
// Initialize the tenant resolver.
app.UseMultitenancy();
app.UseMvc();
}
public class AppTenantContainer : ITenantContainer
{
private readonly IServiceCollection _applicationServices;
public AppTenantContainer(IServiceCollection applicationServices)
{
_applicationServices = applicationServices;
}
public IServiceProvider CreateChildContainer(AppTenant tenant)
{
// Create a new service collection for the tenant.
var tenantServices = new ServiceCollection();
// Add tenant specific services.
tenantServices.AddScoped(provider => new GreetingService(tenant.Name));
// Add the application services to tenant container
tenantServices.Add(_applicationServices);
// Build the container
var tenantContainer = tenantServices.BuildServiceProvider();
return tenantContainer;
}
}
public class TenantResolver : MemoryCacheTenantResolver
{
public TenantResolver(IMemoryCache cache, IConfiguration configuration)
: base(cache)
{
var tenants = new List();
configuration.GetSection("Tenants").Bind(tenants);
foreach (var tenant in tenants)
{
Add(new TenantContext(new Tenant { Id = tenant.Id, Name = tenant.Name },
new TenantRequestIdentifierMiddlewareOption { HostValue = tenant.Hostname }));
}
}
}
public class GreetingController : Controller
{
private readonly AppTenantContainer _tenantContainer;
public GreetingController(AppTenantContainer tenantContainer)
{
_tenantContainer = tenantContainer;
