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

public class httpGet_Test {
    public static void main(String[] args) throws Exception {
        //定义一个HttpClient对象
        CloseableHttpClient httpClient = HttpClients.createDefault();
        //设置请求地址
        URIBuilder uriBuilder = new URIBuilder("http://localhost:8080/jwd/get");
        //设置参数
        uriBuilder.setParameter("jd","33");
        uriBuilder.setParameter("wd","232");
        //创建HttpGet对象 设置url访问地址
        HttpGet httpGet = new HttpGet(uriBuilder.build());
        //打印出请求信息
        System.out.println("::"+httpGet);
        CloseableHttpResponse response = null;
        //使用httpClient发起请求，获取resposen
        response = httpClient.execute(httpGet);
        //判断状态
        if(response.getStatusLine().getStatusCode() == 200){
            //获取返回的信息
            String content = EntityUtils.toString(response.getEntity(), "utf8");
            System.out.println(content);
