在Java中，我们可以使用Apache HttpClient库来发送HTTP请求。以下是一个基本的示例，展示如何发送GET请求：

import org.apache.http.HttpEntity;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;
public class HttpClientExample {
    public static void main(String[] args) {
        // 创建HttpClient实例
        CloseableHttpClient httpClient = HttpClients.createDefault();
        try {
            // 发送GET请求
            HttpGet httpGet = new HttpGet("http://example.com");
            CloseableHttpResponse response = httpClient.execute(httpGet);
            // 获取响应实体
            HttpEntity entity = response.getEntity();
            if (entity != null) {
                String content = EntityUtils.toString(entity);
                System.out.println(content); // 打印请求内容
            }
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            // 关闭资源
            if (httpClient != null) {
                httpClient.close();
            }
        }
    }
}
