saa-调用百度地图MCP服务

#MCP#spring ai alibaba

一、说明

本章节介绍saa调用百度地图MCP服务，这个和之前调用本地mcp服务有点类似，但是一个是本地自有的mcp服务，另外一个是远程mcp服务。有一个前提必须是本地安装有node环境或者python环境。

需要注意的是，我是使用的mac，记得本地文件的授权，不然链接不上远程mcp服务。

二、MCP服务市场

先去mcp服务市场找到我们本次要使用的mcp服务，本次选择的是百度地图的MCP服务，其他的也可以一样使用：

https://mcp.so/zh/server/baidu-map/baidu-maps

"BAIDU_MAP_API_KEY"就是我们在百度地图开发者平台申请的api key，所以先要去该平台注册一个开发者账号（个人/企业都可以），然后申请一个应用。

三、申请百度地图开发者账号并申请应用和获取api key

四、编码

3.properties配置文件

server.port=8094

server.servlet.encoding.charset=utf-8
server.servlet.encoding.enabled=true
server.servlet.encoding.force=true
spring.application.name=saa-client-call-baidu-mcp-server

spring.ai.dashscope.api-key=sk-09c7b571687b46d5a2e25a03fbdd2fd1

## mcp-server config
spring.ai.mcp.client.request-timeout=30s
spring.ai.mcp.client.toolcallback.enabled=true
spring.ai.mcp.client.stdio.servers-configuration=classpath:/mcp-server-config.json

4.配置类SaaLLMConfig

package com.saa.client.call.baidu.mcp.server.config;

import org.springframework.ai.chat.client.ChatClient;
import org.springframework.ai.chat.model.ChatModel;
import org.springframework.ai.tool.ToolCallbackProvider;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class SaaLLMConfig {
    @Bean
    public ChatClient chatClient(ChatModel chatModel, ToolCallbackProvider tools) {
        return ChatClient.builder(chatModel)
                //mcp协议，配置见yml文件，此处只赋能给ChatClient对象
                .defaultToolCallbacks(tools.getToolCallbacks())
                .build();
    }
}

5.mcp服务json

{
  "mcpServers": {
    "baidu-map": {
      "command": "npx",
      "args": [
        "-y",
        "@baidumap/mcp-server-baidu-map"
      ],
      "env": {
        "BAIDU_MAP_API_KEY": "IOt1Mah0FdYYwvEnQpWSIdIruRfdxxxx"
      }
    }
  }
}

6.控制器

package com.saa.client.call.baidu.mcp.server.controller;

import jakarta.annotation.Resource;
import org.springframework.ai.chat.client.ChatClient;
import org.springframework.ai.chat.model.ChatModel;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
import reactor.core.publisher.Flux;

@RestController
public class McpClientCallBaiDuMcpController {

    @Resource
    private ChatClient chatClient; //添加了MCP调用能力

    @Resource
    private ChatModel chatModel; //没有添加MCP调用能力

    
    @GetMapping("/mcp/chat")
    public Flux<String> chat(@RequestParam("msg") String msg) {
       return chatClient.prompt()
                .system("请用html格式回复")
                .user(msg)
                .stream().content();
    }

    @RequestMapping("/mcp/chat2")
    public Flux<String> chat2(@RequestParam("msg") String msg) {
        return chatModel.stream(msg);
    }
}

五、测试

1.启动程序会看到加载JSON后，百度地图MCP SERVER相关信息

出现这个表示链接百度地图MCP服务成功。

2.接口测试

测试1：http://localhost:8094/mcp/chat?msg=查询北纬30.5042东经114.4074天气

测试2:

http://localhost:8094/mcp/chat?msg=查询光谷到黄鹤楼路线

测试3:

http://localhost:8094/mcp/chat2?msg=查询北纬30.5042东经114.4074天气

人的一生应该怎样度过？
