如何在Spring Boot中自动连接OkHttpClient bean?

我想 autowire 一个例子 OkHttpClient 在我的控制器课上。我创造了一个 OkHttpClientFactory 类并将其标记为 Bean 在它的构造函数中。我把这个作为一个例子 Autowired 在控制器类中。然而,我遇到了以下问题-

豆子-

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import okhttp3.OkHttpClient;

@Configuration

public class OkHttpClientFactory {
    @Bean
    public OkHttpClient OkHttpClientFactory() {
        return new OkHttpClient();
    }


}

控制器-

import java.io.IOException;

import org.json.JSONObject;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import com.sap.lmc.beans.OkHttpClientFactory;

import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.Response;

@RestController
@RequestMapping("/recast")
public class Test {

    @Autowired
    private OkHttpClientFactory client;

    private String url = "https://example.com/";

    @GetMapping(path="/fetchResponse", produces="application/json")
    public String getRecastReponse() {

        Request request = new Request.Builder().url(url).build();
        try {
            Response response = client.newCall(request).execute();
            JSONObject json = new JSONObject();
            json.put("conversation",response.body().string());
            return json.toString();
        } catch (IOException e) {
            return e.getMessage().toString();
        }   
    }

}

以下是错误结果-

java.lang.Error: Unresolved compilation problem: 
    The method newCall(Request) is undefined for the type OkHttpClientFactory

不是吗 自动装配 OkHttpClientFactory 实例实际返回 OkHttpClient 类型那为什么是这种方法呢 newCall() 不适用吗?
