在下面的方法中，当我从TestNG运行它时得到IOException（这是预期的），但我看到的只是InitConnectionException而不是原因。谁知道为什么会这样？
private void setupConnectionStreams(HttpsURLConnection connection) throws InitConnectionException {
try {
dataOutStream = new DataOutputStream(connection.getOutputStream());
dataInStream = new DataInputStream(connection.getInputStream());
} catch (IOException e) {
throw new InitConnectionException(e.getCause());
}
}
public class InitConnectionException extends Exception{
private static final long serialVersionUID = 1L;
public InitConnectionException(){
super("There was a problem to setup a initialize a connection to the server.");
}
public InitConnectionException(String msg){
super(msg);
}
public InitConnectionException(Throwable cause) {
super(cause);
}
}
