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-key
      base-url: https://api.deepseek.com
      chat:
        options:
          model: deepseek-chat

编写配置类：

@Configuration
public class ChatConfig {
    @Bean
    public 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！
