I'm using spring-social-facebook
and sometimes, after some time the authentication seems to expire and I get this exception:
org.springframework.social.ExpiredAuthorizationException: The authorization has expired.
at org.springframework.social.facebook.api.impl.FacebookErrorHandler.handleFacebookError(FacebookErrorHandler.java:83)
at org.springframework.social.facebook.api.impl.FacebookErrorHandler.handleError(FacebookErrorHandler.java:59)

at org.springframework.web.client.RestTemplate.getForObject(RestTemplate.java:303)
at org.springframework.social.facebook.api.impl.SocialContextTemplate.getSocialContext(SocialContextTemplate.java:120)
I don't know how to handle with this error...Would it be possible to automatically reconnect after the authentication expires?

Any help would be apreciated.
To fix this issue you must add a ReconnectFilter
to the social configuration Java file:
@Bean
public ReconnectFilter apiExceptionHandler(UsersConnectionRepository usersConnectionRepository, UserIdSource userIdSource) {
return new ReconnectFilter(usersConnectionRepository, userIdSource);
}
This ReconnectFilter
depends on an UserIdSource Bean to retrieve the user information and refresh the connection. You must override it:
@Override
@Bean
public UserIdSource getUserIdSource() {
return new UserIdSource() {
@Override
public String getUserId() {
User user = getUser();
if (user == null) {
throw new IllegalStateException("Unable to get a ConnectionRepository: no user signed in");
}
return user.getId();
}
};
}
You can see the entire Social Config file below:
@Configuration
@PropertySource("classpath:application.properties")
@EnableSocial
public class SocialConfig extends SocialConfigurerAdapter {
@Override
public void addConnectionFactories(ConnectionFactoryConfigurer cfConfig, Environment env) {
cfConfig.addConnectionFactory(new FacebookConnectionFactory(env.getProperty("facebook.appKey"), env.getProperty("facebook.appSecret")));
}
@Bean
public UsersConnectionRepository usersConnectionRepository(ConnectionFactoryLocator connectionFactoryLocator) {
return new UserConnectionRepositoryImpl(connectionFactoryLocator);
}
@Override
@Bean
public UserIdSource getUserIdSource() {
return new UserIdSource() {
@Override
public String getUserId() {
User user = getUser();
if (user == null) {
throw new IllegalStateException("Unable to get a ConnectionRepository: no user signed in");
}
return user.getId();
}
};
}
@Bean
public ReconnectFilter apiExceptionHandler(UsersConnectionRepository usersConnectionRepository, UserIdSource userIdSource) {
return new ReconnectFilter(usersConnectionRepository, userIdSource);
}
@Bean
@Scope(value = "request", proxyMode = ScopedProxyMode.INTERFACES)
public ConnectionRepository connectionRepository(ConnectionFactoryLocator connectionFactoryLocator) {
User user = getUser();
if (user == null) {
throw new IllegalStateException("Unable to get a ConnectionRepository: no user signed in");
}
return usersConnectionRepository(connectionFactoryLocator).createConnectionRepository(user.getId());
}
@Bean
@Scope(value = "request", proxyMode = ScopedProxyMode.INTERFACES)
public Facebook facebook(ConnectionRepository repository) {
Connection<Facebook> connection = null;
if (repository != null) {
connection = repository.findPrimaryConnection(Facebook.class);
}
return connection != null ? connection.getApi() : null;
}
}
