一、概述
MCP架构图

MCP生命周期

二、创建MCP SERVER的java工程
生成初始化工程代码
访问网址:https://start.spring.io/
填写基本信息→添加依赖项

选择Server

点击生成


解压后用IDEA打开
修改pom.xml文件
把spring-ai-starter-mcp-server依赖改为spring-ai-starter-mcp-server-webmvc

完整pom.xml内容

定义服务类MathTool

package com.example.tool;
import org.springframework.ai.tool.annotation.Tool;
public class MathTool {
@Tool(description = "两个数字相加")
public static int addNumbers(int a, int b) {
return a + b;
}
@Tool(description = "两个数字相减")
public static int subtractNumbers(int a, int b) {
return a - b;
}
}
通过配置类的方式把MathTool注入到Spring容器中
创建config包,在下面创建McpConfig类

package com.example.test_mcp_server.config;
import com.example.tool.MathTool;
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 McpConfig {
@Bean
public ToolCallbackProvider mathTool() {
return MethodToolCallbackProvider.builder()
.toolObjects(new MathTool())
.build();
}
}
修改配置文件application.yaml
配置内容为:
server:
port: 8080
spring:
application:
name: math_mcp_server
ai:
mcp:
server:
enabled: true
name: test_mcp_server
version: 1.0.0
sse-endpoint: /api/v1/sse
sse-message-endpoint: /api/v1/mcp
capabilities:
tool: true
logging:
level:
# 查看MCP详细日志
io.modelcontextprotocol: TRACE
org.springframework.ai.mcp: TRACE
启动服务

启动成功,并提示注册了两个Tool

三、如何使用MCP Server
方式一:使用Chatbox连接MCP Server
设置AI模型提供方

我这里选择智谱的ChatGLM6B, API密钥去智谱官网申请,点击检查


点确认


配置MCP服务器
点击左侧的MCP

添加服务器


配置信息后点击测试

编写的两个工具成功显示

**PS:必须点测试,这样才能完成服务端的初始化连接**
服务端日志:

点击保存

使用MCP Server
按ECS键退出设置,点击新对话,可以看到刚才添加的MCP服务

输入“运维小兵的计算服务有哪些功能”
AI给的回复很好的总结了工具的功能

问:8加7等于几
工具成功调用

服务端日志内容

测试完毕,符合预期
方式二:开发一个Client来连接Server
创建java工程
跟创建MCP Server类似,改下Artifact名字

添加Client的依赖

保存工程文件,解压后用IDEA打开
修改pom.xml,添加核心依赖
<properties>
<java.version>17</java.version>
<spring-ai.version>1.1.2</spring-ai.version>
</properties>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<!--调用智谱系列大模型的依赖-->
<dependency>
<groupId>org.springframework.ai</groupId>
<artifactId>spring-ai-starter-model-zhipuai</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.ai</groupId>
<artifactId>spring-ai-starter-mcp-client-webflux</artifactId>
</dependency>
</dependencies>
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.ai</groupId>
<artifactId>spring-ai-bom</artifactId>
<version>${spring-ai.version}</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
配置application.yaml
server:
port: 8081
spring:
application:
name: test-mcp-client
ai:
zhipuai:
# 智谱官网创建API Key,配置到机器的环境变量ZHIPU_KEY
api-key: ${ZHIPU_KEY}
base-url: "https://open.bigmodel.cn/api/paas" # 配置模型地址
chat:
options:
model: glm-4-flash
mcp:
client:
sse:
connections:
server1:
# 填写MCP Server的地址
url: http://localhost:8080
sse-endpoint: /api/v1/sse
创建Controller

ConnectMcpServer.java
package com.example.test_mcp_client.controller;
import org.springframework.ai.chat.client.ChatClient;
import org.springframework.ai.tool.ToolCallbackProvider;
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;
@RestController
@RequestMapping("/mcp")
public class ConnectMcpServer {
private final ChatClient chatClient;
public ConnectMcpServer(ChatClient.Builder builder, ToolCallbackProvider toolCallbackProvider) {
this.chatClient = builder
.defaultToolCallbacks(toolCallbackProvider.getToolCallbacks())
.build();
}
@GetMapping("/test")
public String test(@RequestParam(name = "query") String query) {
return chatClient.prompt()
.system("你是一个有用的AI助手")
.user(query)
.call().content();
}
}
启动Client服务
服务启动成功

SERVER端完成初始化

访问接口进行测试
GET http://localhost:8081/mcp/test?query=8加6等于几

查看SERVER日志

完美。
