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}
}
