Integrate ChatGPT with Spring Boot and RSocket: A Step-by-Step Guide

What is ChatGPT

ChatGPT is a chatbot model developed by OpenAI that can understand and generate human language, interact based on context, and assist with various tasks.

What is RSocket

RSocket is a new, language‑agnostic, seventh‑layer application network protocol. It is a binary protocol that supports bidirectional, multiplexed, message‑based, reactive‑stream back‑pressure communication.

Unlike the traditional HTTP request/response model, RSocket also supports Fire‑And‑Forget, Stream, and Channel interaction patterns.

For details on using RSocket, refer to the author's article: RSocket | The Ideal Alternative to REST (http://mp.weixin.qq.com/s?...)

Project Setup

1. Add Dependencies

chatgpt-spring-boot-starter is a starter based on openai‑api that integrates smoothly with Spring Boot. It uses the official API, ensuring stability.

<code><!-- chatgpt 调用封装: https://github.com/flashvayne/chatgpt-spring-boot-starter -->
<dependency>
  <groupId>com.pig4cloud.plugin</groupId>
  <artifactId>chatgpt-spring-boot-starter</artifactId>
  <version>0.0.1</version>
</dependency>
<!-- rsocket dependency, optional -->
<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-rsocket</artifactId>
</dependency>
</code>

2. Obtain ChatGPT API Keys

Visit: https://platform.openai.com/account/api-keys

3. Configure Call Parameters

application.properties

<code>chatgpt.api-key=XXX

# Enable RSocket interaction by configuring the port
spring.rsocket.server.port=18090
</code>

Testing the Call

Using the rsc client, you can easily debug RSocket (similar to an HTTP Postman tool).

<code>./rsc  tcp://localhost:18090  -r chat -d  -  --channel
</code>

Advanced Usage

Inject the ChatgptService bean wherever needed, then call its methods to send messages to ChatGPT and receive replies.

<code>@Autowired
private ChatgptService chatgptService;

public void test() {
    String responseMessage = chatgptService.sendMessage("how are you");
    System.out.print(responseMessage);
}
</code>

ChatgptService provides two methods:

<code>String sendMessage(String message); // Returns ChatGPT's reply directly.
ChatResponse sendChatRequest(ChatRequest request); // Allows custom request parameters and returns the full API response.
</code>

This bean is conditionally injected with @ConditionalOnMissingBean(ChatgptService.class); you can customize it by implementing the interface and overriding the default implementation.

Special Note

Use the above toolkit within the limits of your network permissions!
