springboot实现gpt的eventstream案例

springboot实现gpt的eventstream案例

一、maven坐标

引入webflux依赖

  <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-webflux</artifactId>
        </dependency>

二、democontroller

package org.example.webfluxdemo;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
import reactor.core.publisher.Flux;
import java.time.Duration;

@RestController
public class EventStreamController {

    @GetMapping(value = "/events", produces = "text/event-stream")
    public Flux<String> events() {
        return Flux
                .interval(Duration.ofSeconds(1))  // 每1秒产生一个数据
                .map(l -> "Data: " + l);          // 将长整型数据转换为字符串
    }
}
