HttpClient4.3中EntityUtils.consume方法的含义？

Question

//下面代码出自HttpClient4.3,请问这句代码如何理解？
EntityUtils.consume(entity1);

CloseableHttpClient httpclient = HttpClients.createDefault();

HttpGet httpGet = new HttpGet("http://targethost/homepage");

CloseableHttpResponse response1 = httpclient.execute(httpGet);

try {

    System.out.println(response1.getStatusLine());

    HttpEntity entity1 = response1.getEntity();

    EntityUtils.consume(entity1);

} finally {

    response1.close();

}

              

Answer 1

我查了查，好像是1 关闭应该关闭的资源，适当的释放资源 2也可以把底层的流给关闭了 

 //下面是这方法的源码  
public static void consume(final HttpEntity entity) throws IOException {  
if (entity == null) {  
return;  
        }  
        if (entity.isStreaming()) {  
        InputStream instream = entity.getContent();  
if (instream != null) {  
instream.close();  
                }  
         }  
}

Answer 2

 EntityUtils.consume(entity);  是关闭流什么的的吧，我猜的
