Spring OAuth2 - Manually creating an access token in the token store

Question

I have a situation where I would like to create an access token myself (so not through the usual process). I have come up with something like this:

@Inject
p         


        

Answer 1

This has worked for me:

@Override public OAuth2AccessToken getToken(String username, String password) {
    HashMap parameters = new HashMap();
    parameters.put("client_id", clientid);
    parameters.put("grant_type", "password");
    parameters.put("password", username);
    parameters.put("scope", scope);
    parameters.put("username", password);

    AuthorizationRequest authorizationRequest = defaultOAuth2RequestFactory.createAuthorizationRequest(parameters);
    authorizationRequest.setApproved(true);

    OAuth2Request oauth2Request = defaultOAuth2RequestFactory.createOAuth2Request(authorizationRequest);
    // Create principal and auth token
    final UsernamePasswordAuthenticationToken loginToken = new UsernamePasswordAuthenticationToken(
            username, password);
    Authentication authentication = authenticationManager.authenticate(loginToken);

    OAuth2Authentication authenticationRequest = new OAuth2Authentication(oauth2Request, authentication);
    authenticationRequest.setAuthenticated(true);

    OAuth2AccessToken accessToken = tokenServices.createAccessToken(authenticationRequest);

    return accessToken;
}

In the Oauth2Configuration:

@Bean
    DefaultOAuth2RequestFactory defaultOAuth2RequestFactory() {
    return new DefaultOAuth2RequestFactory(clientDetailsService);
}

The rest of the Oauth2Configuration should look like in the article:
