启动类：

package org.my.mcp.tools;

import org.my.mcp.tools.service.WeatherService;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.ai.tool.ToolCallbackProvider;
import org.springframework.ai.tool.method.MethodToolCallbackProvider;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;


@SpringBootApplication
public class ServerStart {
    private static final Logger logger = LoggerFactory.getLogger(ServerStart.class);

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

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

启动后报错：jackson冲突

Caused by: java.lang.ExceptionInInitializerError: Exception java.lang.NoClassDefFoundError: com/fasterxml/jackson/annotation/JsonSerializeAs [in thread "background-preinit"]

经过Dependency Analyzer分析后，需要约束一下版本，解决包冲突：
