问题现象在Spring AI项目中注入：publicAiService(ChatClient.Builderbuilder){this.chatClient=builder.build();}启动时却出现：No qualifying bean of type 'org.springframework.ai.chat.client.ChatClient$Builder' availableSpring AI官方说明，Spring Boot自动配置会为已配置的ChatModel创建一个原型作用域的ChatClient.Builder。因此，找不到Bean通常不是ChatClient本身的问题，而是模型自动配置链路没有成立。一、先确认依赖是否正确以DeepSeek为例，Spring AI 2.0应使用：dependencygroupIdorg.springframework.ai/groupIdartifactIdspring-ai-starter-model-deepseek/artifactId/dependency同时通过BOM统一版本：dependencyManagementdependenciesdependencygroupIdorg.springframework.ai/groupIdartifactIdspring-ai-bom/artifactId
