httpClient Connection Pool使用的正确姿势

import java.util.concurrent.TimeUnit;

import org.apache.http.client.config.RequestConfig;

import org.apache.http.impl.client.HttpClients;
import org.apache.http.impl.conn.PoolingHttpClientConnectionManager;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;


@Configuration
public class HttpClientConfiguration {
    
    
    @Bean
      public PoolingHttpClientConnectionManager poolingHttpClientConnectionManager() {
        PoolingHttpClientConnectionManager result = 
                new PoolingHttpClientConnectionManager(5, TimeUnit.MINUTES);
        result.setMaxTotal(20);
        result.setDefaultMaxPerRoute(20);
        return result;
      }

      @Bean

          return RequestConfig
                        .custom()
                      .setConnectionRequestTimeout(kycProperties.getHttpConnectionTimeout())
                      .setConnectTimeout(kycProperties.getHttpConnectionTimeout())
