1，首先进入deepseek的官网：DeepSeek | 深度求索，单击右上角的API开放平台。

2，单击API keys，创建一个API，创建完成务必复制！！不然关掉之后会看不看api key！！！

DeepSeek Chat :: Spring AI Reference

创建一个SpringWeb项目，勾选AI下面的Open-Ai,创建成功后就可以进行下一步。

首先把application.property改成application.yml,将以下信息复制到yml里，记得把api-key替换成你自己的！

spring:ai:openai:api-key: api-keybase-url: https://api.deepseek.comchat:options:model: deepseek-chat

编写配置类：

@Configuration
public class ChatConfig {@Beanpublic ChatClient chatClient(OpenAiChatModel openAiChatModel) {return ChatClient.builder(openAiChatModel).build();}
}

编写controller

@RestController
@RequestMapping("/ai")
public class ChatController {private final ChatClient chatClient;public ChatController(ChatClient chatClient) {this.chatClient = chatClient;}@GetMapping("/chat")public String generate(@RequestParam(value = "message", defaultValue = "Tell me a joke") String message) {return chatClient.prompt().user(message).call().content();}
}

启动项目，测试请求

搞定！
