Java Maven Heroku App 中的“java.io.IOException: java.net.BindException: 地址已在使用中”

Question

I am trying to pull data from google sheets using their API and my code works from my local machine. However, after deploying it in Heroku, I get this error. This is the part of the code that I suspected to fail when deployed in Heroku.

private static Credential getCredentials(final NetHttpTransport HTTP_TRANSPORT) throws IOException {
        InputStream in = ProcessGoogleSheets.class.getResourceAsStream(CREDENTIALS_FINAL_PATH);
        if (in == null) {
            throw new FileNotFoundException("Resource not found: " + CREDENTIALS_FINAL_PATH);
        }
        GoogleClientSecrets clientSecrets = GoogleClientSecrets.load(JSON_FACTORY, new InputStreamReader(in));

        GoogleAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow.Builder(
                HTTP_TRANSPORT, JSON_FACTORY, clientSecrets, SCOPES)
                .setDataStoreFactory(new FileDataStoreFactory(new java.io.File(TOKENS_DIRECTORY_PATH)))
                .setAccessType("offline")
                .build();
        LocalServerReceiver receiver = new LocalServerReceiver.Builder().setPort(8080).build();
        return new AuthorizationCodeInstalledApp(flow, receiver).authorize("user");
    }

This is the log returned by Heroku.

Any ideas to fix this? Thanks in advance.

Answer 1

Address already in use -- the address here usually mean PORT .

It seems an application is already running on Heroku on port 8080 , so try changing the port and redeploy and you should be fine.

Answer 2

I used -1 in setPort, this value automatically connects the application to an unused port.

This is the code that works now.

private static Credential getCredentials(final NetHttpTransport HTTP_TRANSPORT) throws IOException {
    InputStream in = ProcessGoogleSheets.class.getResourceAsStream(CREDENTIALS_FINAL_PATH);
    if (in == null) {
        throw new FileNotFoundException("Resource not found: " + CREDENTIALS_FINAL_PATH);
    }
    GoogleClientSecrets clientSecrets = GoogleClientSecrets.load(JSON_FACTORY, new InputStreamReader(in));

    GoogleAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow.Builder(
            HTTP_TRANSPORT, JSON_FACTORY, clientSecrets, SCOPES)
            .setDataStoreFactory(new FileDataStoreFactory(new java.io.File(TOKENS_DIRECTORY_PATH)))
            .setAccessType("offline")
            .build();
    LocalServerReceiver receiver = new LocalServerReceiver.Builder().setPort(-1).build();
    return new AuthorizationCodeInstalledApp(flow, receiver).authorize("user");
}
