1.创建Maven项目
2.Httpclient Maven地址
1 <dependency>
2 <groupId>org.apache.httpcomponents</groupId>
3 <artifactId>httpclient</artifactId>
4 <version>4.5.5</version>
5 </dependency>
在pom.xml文件中添加Httpclient jar包
1 <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
2 xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

8 import org.apache.http.impl.client.CloseableHttpClient;
9 import org.apache.http.impl.client.HttpClients;
10 import org.apache.http.util.EntityUtils;
11
12 public class Test {
13
14 public static void main(String[] args) throws IOException {
15 CloseableHttpClient httpclient=HttpClients.createDefault();
16 HttpGet httpget=new HttpGet("http://www.baidu.com");
17 CloseableHttpResponse response=httpclient.execute(httpget);
18 HttpEntity entity=response.getEntity();
19 System.out.println(entity);
20 String page=EntityUtils.toString(entity, "utf-8");
21 System.out.println(page);
22 response.close();
23 httpclient.close();
24 }
25 }
