import java.net.HttpURLConnection;
import java.net.URL;
import com.test.RestResponse;
import com.fasterxml.jackson.databind.ObjectMapper;

public class Test  {

	private static final ObjectMapper objectMapper = new ObjectMapper();

	//get请求的urlStr
	protected RestResponse getRestResponse(String urlStr) throws Exception {
		URL url = new URL(urlStr);
		HttpURLConnection huc = (HttpURLConnection) url.openConnection();
		InputStream is = huc.getInputStream();
		InputStreamReader isr=new InputStreamReader(is,"utf-8");
		BufferedReader br=new BufferedReader(isr);
		StringBuffer buffer=new StringBuffer();
		String line=null;
		while((line=br.readLine())!=null){
			buffer.append(line);
		}
		//RestResponse 自己定义的接收数据model
		RestResponse response = objectMapper.readValue(buffer.toString(), RestResponse.class);
		return response;
	}
