使用Spring的WebClient发送包含大列表的对象

import org.springframework.web.reactive.function.client.WebClient;
import reactor.core.publisher.Flux;
import reactor.core.publisher.Mono;

import java.util.List;

public class WebClientExample {

    public static void main(String[] args) {
        WebClient webClient = WebClient.builder().build();

        List<String> largeList = generateLargeList(); // 生成大列表

        Flux.fromIterable(largeList)
            .buffer(100) // 每100个元素分一批
            .flatMap(batch -> webClient.post()
                .uri("https://example.com/api")
                .bodyValue(batch)
                .retrieve()
                .bodyToMono(String.class))
            .doOnNext(response -> System.out.println("Response: " + response))
            .blockLast(); // 等待所有请求完成
    }

    private static List<String> generateLargeList() {
        // 生成大列表的逻辑
        return List.of("item1", "item2", "item3", /* ... */);
    }
}
