3. Usage

3.1 構造注入

直接構造注入即可使用。

public TodoController(IKnowledgeApplicationService knowledgeApplicationService, ITCPCollectorApplicationService tcpCollectorApplicationService, IServiceProvider serviceProvider) {KnowledgeApplicationService = knowledgeApplicationService;TCPCollectorApplicationService = tcpCollectorApplicationService;ServiceProvider = serviceProvider; }
