1、pom添加内容
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpasyncclient</artifactId>
<version>4.1</version>
</dependency>
2、创建httpUtil
public class HttpUtil {
private static int socketTimeout = 1000;// 设置等待数据超时时间5秒钟 根据业务调整
private static int connectTimeout = 2000;// 连接超时
private static int poolSize = 100;// 连接池最大连接数
private static int maxPerRoute = 10;// 每个主机的并发最多10

} catch (KeyManagementException e) {
e.printStackTrace();
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
} catch (KeyStoreException e) {

/**

}
if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {

}
if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
ip = request.getRemoteAddr();
}
return ip;
}
}
3、创建一个提供外部获取httpClient接口
/**
* AsynHttpClient工厂类
*/
@Component
public class AsynHttpClientFactory {
private static Logger logger = LoggerFactory.getLogger(AsynHttpClientFactory.class);
private static CloseableHttpAsyncClient httpclient;
private PoolingNHttpClientConnectionManager connManager;
public AsynHttpClientFactory() {
connManager = HttpUtil.getConnManager();
httpclient = HttpUtil.getClient(connManager);
httpclient.start();
logger.info("异步httpClient启动完成");
}
public static CloseableHttpAsyncClient getCloseableHttpAsyncClient(){
return httpclient;
}
}
4、测试方法
单个url发送
@Test
public void run(){
CloseableHttpAsyncClient httpClient =AsynHttpClientFactory.getCloseableHttpAsyncClient();
long startTime = System.currentTimeMillis();
final HttpGet request = new HttpGet("http://www.apache.org");
final Future future = httpClient.execute(request, null);
try {
HttpResponse response = (HttpResponse) future.get();
System.out.println("Response:" + request.getURI()+"; "+ response.getStatusLine());
System.out.println("Shutting down");
} catch (Exception ex) {
System.out.println(ex.getMessage());
}finally{
try {
httpClient.close();
} catch (IOException ex) {
System.out.println(ex.getMessage());
}
}
long endTime = System.currentTimeMillis();
System.out.println("执行完毕, 耗时："+(endTime-startTime)/1000+" 秒");
}
多条url发送
@Test
public void moreRequest(){
CloseableHttpAsyncClient httpClient =AsynHttpClientFactory.getCloseableHttpAsyncClient();
long startTime = System.currentTimeMillis();
final HttpGet[] requests = new HttpGet[10];
for (int i = 0; i < requests.length; i++) {
requests[i] = new HttpGet("http://www.apache.org/");
}
final CountDownLatch latch = new CountDownLatch(requests.length);
for(final HttpGet request: requests){
httpClient.execute(request, new FutureCallback(){
@Override
public void completed(Object obj) {
final HttpResponse response = (HttpResponse)obj;
latch.countDown();
System.out.println(request.getURI() + "->" + response.getStatusLine());
}
@Override
public void failed(Exception excptn) {
latch.countDown();
System.out.println(request.getURI() + "->" + excptn);
}
@Override
public void cancelled() {
latch.countDown();
System.out.println(request.getURI() + "cancelled");
}
});
}
try {
latch.await();
System.out.println("Shutting Down");
} catch (InterruptedException ex) {
System.out.println(ex.getMessage());
}finally{
try {
httpClient.close();
} catch (IOException ex) {
System.out.println(ex.getMessage());
}
}
long endTime = System.currentTimeMillis();
System.out.println("执行完毕, 耗时："+(endTime-startTime)/1000+" 秒");
}
