1 引入依赖

<!-- mcp server的核心 -->
<dependency>
    <groupId>org.springframework.ai</groupId>
    <artifactId>spring-ai-mcp-server-webmvc-spring-boot-starter</artifactId>
</dependency>

2 编写代码

@Service
public class WeatherService {

    @Tool(description = "Get weather information by city name")
    public String getWeather(String cityName) {
        // Implementation
    }
}

@SpringBootApplication
public class McpServerApplication {

    private static final Logger logger = LoggerFactory.getLogger(McpServerApplication.class);

    public static void main(String[] args) {
        SpringApplication.run(McpServerApplication.class, args);
    }

	@Bean
	public ToolCallbackProvider weatherTools(WeatherService weatherService) {
		return MethodToolCallbackProvider.builder().toolObjects(weatherService).build();
	}
}
