How to set Redirect URI for OAuth2 for google in java

I run this code but it is giving Error: redirect_uri_mismatch .I set redirect uri in client_secret.json file. But each time redirect uri is like http://localhost:53271/Callback( port number changed each time) but not the one i have given in client_secret.json.
