HttpClient调用外部接口

1、gradle添加包

    implementation 'org.apache.httpcomponents:httpclient:4.5.1'
    implementation 'commons-collections:commons-collections:3.2.2'

2、调用

import org.apache.commons.collections.MapUtils;
import org.apache.http.client.config.RequestConfig;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.client.utils.URIBuilder;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;

import java.util.Map;

import static org.jboss.logging.MDC.getMap;

                for(Map.Entry<String,Object> entry:map.entrySet()){
                    builder.addParameter(entry.getKey(), String.valueOf(entry.getValue()));

            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
