如何在rest api java中实现请求资源最多3次尝试

import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;

public class RestApiExample {
    private static final int MAX_RETRY = 3;
    private static final int RETRY_INTERVAL = 1000; // 1秒

    public static void main(String[] args) {
        String url = "https://api.example.com/resource";

        int retryCount = 0;
        boolean success = false;
        String response = null;

        while (retryCount < MAX_RETRY && !success) {
            try {
                CloseableHttpClient httpClient = HttpClients.createDefault();
                HttpGet httpGet = new HttpGet(url);
                CloseableHttpResponse httpResponse = httpClient.execute(httpGet);

                int statusCode = httpResponse.getStatusLine().getStatusCode();
                if (statusCode == 200) {
                    response = EntityUtils.toString(httpResponse.getEntity());
                    success = true;
                } else {
                    // 根据具体的错误情况决定是否继续尝试
                    // 这里可以根据不同的状态码进行不同的处理
                    // 例如，如果是503错误，可以等待一段时间后再次尝试
                    // Thread.sleep(RETRY_INTERVAL);
                }

                httpClient.close();
            } catch (Exception e) {
                // 发生异常时继续尝试
                // 可以根据具体的异常类型进行不同的处理
                // 例如，如果是连接超时异常，可以等待一段时间后再次尝试
                // Thread.sleep(RETRY_INTERVAL);
            }

            retryCount++;
        }

        if (success) {
            // 处理返回的资源数据
            System.out.println("Response: " + response);
        } else {
            // 达到最大尝试次数仍然失败，抛出异常或返回错误信息
            System.out.println("Failed to get resource after " + MAX_RETRY + " retries.");
        }
    }
}
