减少依赖注入。

[LYZhelloworld]

依赖注入通过反射动态绑定对象，容易出现调用层次不明确、难以追踪组件间关系的问题。尽量手动创建对象。

当前的依赖关系：

@startuml Current Design
skinparam linetype ortho
left to right direction

package "Api" {
    [CopilotOperationController]
    [CopilotUserController]
    [CurrentUserService]
}

package "Application" {
    [Handlers (Operation)]
    [Handlers (User)]
}

package "Infrastructure" {
    [MaaCopilotDbContext]
    [CopilotIdService]
    [IdentityService]
    [MailService]
    [SecretService]
}

package "Resources" {
    [ValidationErrorMessage]
    [ApiErrorMessage]
}

[TokenOption]
[DatabaseOption]
[ApplicationOption]
[JwtOption]
[Configuration]

[HttpContextAccessor]
[FluentEmail]

[CopilotOperationController] --> [Handlers (Operation)]
[CopilotUserController] --> [Handlers (User)]

[Handlers (Operation)] --> [CopilotIdService]
[Handlers (Operation)] --> [CurrentUserService]
[Handlers (Operation)] --> [MaaCopilotDbContext]
[Handlers (Operation)] --> [IdentityService]
[Handlers (Operation)] --> [ValidationErrorMessage]
[Handlers (Operation)] --> [ApiErrorMessage]

[Handlers (User)] --> [MaaCopilotDbContext]

预计重构后的依赖关系（移动了部分组件所在的项目，避免循环引用）：

@startuml Refactored Design
skinparam linetype ortho
left to right direction

package "Api" {
    [CopilotOperationController]
    [CopilotUserController]
}

package "Application" {
    [Handlers (Operation)]
    [Handlers (User)]
    [CurrentUserService]
    [CopilotIdService]
    [IdentityService]
    [MailService]
    [SecretService]
}

package "Infrastructure" {
    [MaaCopilotDbContext]
}

package "Resources" {
    [ValidationErrorMessage]
    [ApiErrorMessage]
}

package "Options" {
    [Configuration]
    [TokenOption]
    [DatabaseOption]
    [ApplicationOption]
    [JwtOption]
}

[HttpContextAccessor]
[FluentEmail]

[CopilotOperationController] --> [Handlers (Operation)]
[CopilotUserController] --> [Handlers (User)]

[Handlers (Operation)] --> [CopilotIdService]
[Handlers (Operation)] --> [CurrentUserService]
[Handlers (Operation)] --> [MaaCopilotDbContext]
[Handlers (Operation)] --> [IdentityService]
[Handlers (Operation)] --> [ValidationErrorMessage]
[Handlers (Operation)] --> [ApiErrorMessage]

[Handlers (User)] --> [MaaCopilotDbContext]
[Handlers (User)] --> [CopilotIdService]
[Handlers (User)] --> [CurrentUserService]
[Handlers (User)] --> [MailService]
[Handlers (User)] --> [SecretService]
[Handlers (User)] --> [TokenOption]
[Handlers (User)] --> [ApiErrorMessage]

[CurrentUserService] --> [Configuration]
[CurrentUserService] --> [HttpContextAccessor]
