SpringBoot 整合 MCP
MCP
MCP 协议主要分为:
- Client 客户端(一般就是指 openai,deepseek 这些大模型)
 - Server 服务端(也就是我们的业务系统)我们要做的就是把我们存量系统配置成 MCP Server
 
环境
- JDK17
 - SpringBoot 3

配置 yaml
spring:
  ai:
    openai:
      base-url: https://api.deepseek.com
      api-key: sk-xxxxxxxx			# deepseek 的 api-key
      chat:
        enabled: true
        options:
          model: deepseek-chat		# 使用这个模型
          temperature: 0.7
          stream-usage: true		# 有的模型不支持
logging:
  level:
    org.springframework.ai: debug	# 开启 debug,打印思考链路
 
工具类
工具类的作用就是获取 springboot 里所有需要注册的 bean,这里是策略是 获取所有 “Controller”, “Service”, “Manager” 结尾的 bean,可以自行修改。

修改源码
主要在方法上添加注解,注意 name 有命名规范,不能是中文,最好类似 selectMenuIdsByRoleIds。
-  
@Tool(name = "selectMenuIdsByRoleIds", description = "根据角色id列表查询菜单id列表") 
还可以在字段,方法参数上添加
-  
@ToolParam(description = "角色id列表") 
    /**
     * 根据角色id查询菜单id
     *
     * @param roleIds 角色id
     * @return 菜单id, 平铺, 去重
     */
    @Tool(name = "selectMenuIdsByRoleIds", description = "根据角色id列表查询菜单id列表")
    public List<Long> selectMenuIdsByRoleIds(@ToolParam(description = "角色id列表") List<Long> roleIds) {
        List<RoleMenuPo> poList = roleMenuRepository.findByRoleIdIn(roleIds);
        List<Long> menuIdList = poList.stream().map(RoleMenuPo::getMenuId).distinct().collect(Collectors.toList());
        log.info("根据角色id查询菜单id, roleIds:{}, menuIdList:{}", roleIds, menuIdList);
        return menuIdList;
    }

接口访问
调用接口

http://127.0.0.1:8080/ai/v1/chat/stream
 
前端代码 vue3

实现效果
通过自然语言实现,调用内部函数或接口,
 虽然略有瑕疵,但是 领导说了,先上线吧,以后慢慢优化
