怎样用java调用https接口

Posted 2023-04-04

参考技术A 下面这个函数可以直接用：
public static String requsetUrl(String urls) throws Exception
BufferedReader br = null;
String sTotalString= "";
try
URL url = new URL(urls);
URLConnection connection = url.openConnection();
connection.setConnectTimeout(3000);
connection.setDoOutput(true);
String line = "";
InputStream l_urlStream;
l_urlStream = connection.getInputStream();

br = new BufferedReader(new InputStreamReader(l_urlStream, "UTF-8"));
while ((line = br.readLine()) != null)
sTotalString += line + "\r\n";

finally
if(br!=null)
try
br.close();
catch (IOException e)
br = null;



return sTotalString;

参考技术A net.sf.hibernate.MappingException
当出现net.sf.hibernate.MappingException: Error reading resource:…异常时一般是因为映射文
件出现错误。

当出现net.sf.hibernate.MappingException: Resource: … not found是因为XML配置文件没找到所致，有可能是放置目录不正确，或者没将其加入hibernate.cfg.xml中。
