java用HttpClientConnection实现多个互联网图片下载

以下是使用HttpClientConnection实现多个互联网图片下载的Java代码示例：

import java.io.*;
import java.util.*;

import org.apache.commons.io.*;
import org.apache.http.*;
import org.apache.http.client.*;
import org.apache.http.client.methods.*;
import org.apache.http.impl.client.*;
import org.apache.http.protocol.*;

public class HttpClientExample {

    public static void main(String[] args) throws Exception {
        List<String> urls = Arrays.asList(
            "https://example.com/image1.jpg",
            "https://example.com/image2.jpg",
            "https://example.com/image3.jpg"
        );
        String outputDir = "C:/downloads/";

        HttpClient client = new DefaultHttpClient();
        HttpContext context = new BasicHttpContext();

        for (String url : urls) {
            HttpGet request = new HttpGet(url);
            HttpResponse response = client.execute(request, context);
            HttpEntity entity = response.getEntity();
            InputStream input = entity.getContent();
            String filename = FilenameUtils.getName(url);
            File output = new File(outputDir + filename);
            FileUtils.copyInputStreamToFile(input, output);
            EntityUtils.consume(entity);
        }

        client.getConnectionManager().shutdown();
    }

}

这个示例代码使用了Apache HttpClient库来发送HTTP GET请求，并将响应的图片数据保存到本地文件中。它可以处理多个URL，并将下载的文件保存到指定目录中
