Spring Webclient:illegalargumentexception没有足够的变量来展开“comment\u count”

但是,得到这个例外

java.lang.IllegalArgumentException: Not enough variable values available to expand reactive spring

代码段:

import org.springframework.stereotype.Component;
import org.springframework.web.reactive.function.client.WebClient;

import reactor.core.publisher.Mono;

@Component
public class Stackoverflow {

    WebClient client = WebClient.create();

    public Mono<Post> fetchPost(String url) {
        // Url contains "comments{comment_count}"
        return client.get().uri(url).retrieve()
                .bodyToMono(Post.class);
    }
}

我知道restemplate的解决方案,但我需要使用spring webclient。
