配置下端口号

复制代码

server.port=9999

写一个配置类和tool

复制代码

package com.ruoyi.mcpserver;


import org.springframework.ai.tool.ToolCallbackProvider;
import org.springframework.ai.tool.annotation.Tool;
import org.springframework.ai.tool.annotation.ToolParam;
import org.springframework.ai.tool.method.MethodToolCallbackProvider;
import org.springframework.context.annotation.Bean;
import org.springframework.stereotype.Service;

@Service
public class User {

    @Tool(description = "获取用户分数")
    public Integer getScore(@ToolParam(description = "用户名") String userName) {
        if ("zhangsan".equals(userName)) return 11;
        if ("lisi".equals(userName)) return 22;

        return 0;
    }



}


package com.ruoyi.mcpserver;

import org.springframework.ai.tool.ToolCallbackProvider;
import org.springframework.ai.tool.method.MethodToolCallbackProvider;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class Config {

    @Bean
    public ToolCallbackProvider userProvider(User  user) {
        return MethodToolCallbackProvider.builder().toolObjects(user).build();
    }
}

启动项目

访问http://localhost:9999/sse

服务器端启动成功

maven package 产生jar包

在cmd命令行中java -jar xxx.jar启动

client增加配置

复制代码

spring.ai.mcp.client.sse.connections.s1.url=http://localhost:9999

重新启动client端

问个server端的问题

服务确实由mcp server提供

成功！
