如何从HttpEntity Java中仅获取Json内容

import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;

public class JsonFromHttpEntityExample {
    public static void main(String[] args) {
        HttpClient httpClient = HttpClientBuilder.create().build();
        HttpGet httpGet = new HttpGet("http://example.com/api/data");

        try {
            HttpResponse response = httpClient.execute(httpGet);
            HttpEntity entity = response.getEntity();

            if (entity != null) {
                String jsonString = EntityUtils.toString(entity);
                // 在这里可以对jsonString进行解析和处理
                System.out.println(jsonString);
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
