步骤

1.  创建HttpClient对象
2.  创建请求方法的实例
3.  调用HttpClient对象的execute发送请求，该方法返回一个HttpResponse
4.  通过Response获取此响应的消息实体
5.  返回字符串

import com.cyh.impl.DeraultChapterSpider;
    import com.cyh.interfaces.IChapterSpider;
    import com.cyh.pojo.Chapter;
    import org.apache.http.HttpEntity;
    import org.apache.http.HttpResponse;
    import org.apache.http.client.HttpClient;
    import org.apache.http.client.methods.HttpGet;
    import org.apache.http.impl.client.HttpClients;
    import org.apache.http.util.EntityUtils;
    import org.jsoup.Jsoup;
    import org.jsoup.nodes.Document;
    import org.junit.Test;
    
    import java.io.IOException;
    import java.util.List;
    
    public class NovelTest {
    
        @Test
        public void test2(){
            try {
                String url = "https://www.bxwx9.org/b/58/58522/index.html";
                HttpClient client = HttpClients.createDefault(); 
                HttpGet get = new HttpGet(url);
                HttpResponse response = client.execute(get);
                HttpEntity entity = response.getEntity();
                System.out.println(entity);
                System.out.println(EntityUtils.toString(entity,"utf-8"));
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }

通过Jsoup的方法也可以发起get请求， 得到网页源码很简单

Jsoup.connect("http://example.com/").get();
