Spring ai 快速入门及使用，构建你自己的ai

第一步：创建springboot项目 jdk必须是17及以上 1.8用不了

第二步选择web和ai的依赖选择openai

第三步需要配置openai key 配置

分享个免费或的apikey的地方New API 会免费赠送1刀的token

spring.application.name=springAI
spring.ai.openai.base-url=https://api.xty.app
spring.ai.openai.api-key=sk-DvbisfiKYZMkKjxICe542cEe16B74d41B763E23c449d83Ed
spring.ai.openai.chat.options.model=gpt-3.5-turbo
server.port=8811

第四步创建个controller


import org.springframework.ai.chat.ChatResponse;
import org.springframework.ai.chat.messages.UserMessage;
import org.springframework.ai.chat.prompt.Prompt;
import org.springframework.ai.openai.OpenAiChatClient;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;
import reactor.core.publisher.Flux;

import java.util.Map;

@RestController

public class ChatController {

    private final OpenAiChatClient chatClient;

    @Autowired
    public ChatController(OpenAiChatClient chatClient) {
        this.chatClient = chatClient;
    }

    @GetMapping("/ai/generate")
    public Map generate(@RequestParam(value = "message", defaultValue = "讲个笑话") String message) {
        return Map.of("generation", chatClient.call(message));
    }

    @GetMapping("/ai/generateStream")
    public Flux<ChatResponse> generateStream(@RequestParam(value = "message", defaultValue = "Tell me a joke") String message) {
        Prompt prompt = new Prompt(new UserMessage(message));
        return chatClient.stream(prompt);
    }
}

前端页面

<script setup lang="ts">
 import {ref} from 'vue'
 
const msg = ref('');
const res = ref([]);

const sendMsg = ()=>{
  const message = encodeURIComponent(msg.value);
 let source = new EventSource(`http://localhost:8811/ai/generateStream?message=${message}`)
 let count =0;
 source.onmessage = (e)=>{
   console.log(e.data)
   if(e.data==='') 
   {
    count++;
   }
   if(count===2)
   {
    source.close;
   }
   res.value.push(e.data)
   
 
  }
}

</script>
