如何使用Groovy同时运行两次REST请求测试步骤？

import groovy.json.JsonSlurper
import groovy.util.logging.Slf4j
import org.apache.http.HttpEntity
import org.apache.http.HttpResponse
import org.apache.http.client.methods.HttpGet
import org.apache.http.impl.client.CloseableHttpClient
import org.apache.http.impl.client.HttpClients

@Slf4j
class RestRequestThread extends Thread {
    String url

    RestRequestThread(String url) {
        this.url = url
    }

    void run() {
        CloseableHttpClient httpClient = HttpClients.createDefault()
        HttpGet httpGet = new HttpGet(url)
        HttpResponse response = httpClient.execute(httpGet)
        HttpEntity entity = response.getEntity()
        String responseString = entity.getContent().text
        log.info("Response: ${responseString}")
    }
}

def url = "https://api.example.com/resource"

def thread1 = new RestRequestThread(url)
def thread2 = new RestRequestThread(url)

thread1.start()
thread2.start()

thread1.join()
thread2.join()
