Spring Data - MongoDB - Doesn't write GrantedAuthority instances

[chiwi]

Hey there, I'm using SpringData MongoDB - latest snapshot, and Spring Security 3.0.5.

I have the following class I want to persist:

@Document
public class MyUser implements UserDetails {

	@Id
	private String username;
	private String password;
	private boolean accountEnabled = true;
	private List<GrantedAuthority> authorities = new ArrayList<GrantedAuthority>();

...getters/setters...
}

I have also created a new UserDetailsManager since there is none that uses mongoDb as a db backend.

public class UserDetailsManagerMongoImpl implements UserDetailsManager {
	
	@Autowired
	private MongoTemplate template;
	
	
	@Override
	public void createUser(UserDetails user) {
		MyUser myUser = (MyUser) user;
		template.insert("users", myUser);
	}

[...]
}

But even though I set the roles correctly to the user (i can see them when I debug the app), whenever I store the user, it doesn't persist the roles, it writes this:

{ "_id" : "someId", "_class" : "com.x.y.z.MyUser", "authorities" : [ { } ], "accountEnabled" : true, "password" : "mysecret" }

Note the empty authorities.

I started to debug the MappingMongoConverter, and found out that is converting the List<GrantedAuthority>, when it tries to convert each roles (GrantedAuthorityImpl), it skips the following code in MappingMongoConverter:

		// Write the properties
		entity.doWithProperties(new PropertyHandler<MongoPersistentProperty>() {
			public void doWithPersistentProperty(MongoPersistentProperty prop) {
				Object propertyObj;
				try {
					propertyObj = getProperty(obj, prop, prop.getType(), useFieldAccessOnly);
				} catch (IllegalAccessException e) {
					throw new MappingException(e.getMessage(), e);
				} catch (InvocationTargetException e) {
					throw new MappingException(e.getMessage(), e);
				}
				if (null != propertyObj) {
					if (!isSimpleType(propertyObj.getClass())) {
						writePropertyInternal(prop, propertyObj, dbo);
					} else {
						writeSimpleInternal(prop.getKey(), propertyObj, dbo);
					}
				}
			}
		});

this is in method protected void writeInternal(final Object obj, final DBObject dbo, MongoPersistentEntity<?> entity). I don't know if it has anything to do, but seemed strange.

Do I have to add a converter for GrantedAuthorityImpl?

Thank you very much

Fede.
