MongoUserDetailsService in java config returns null - mongodb

Question

Anybody can see why I get null when returning Customer?
I'm using java config and are able to connect to DB by my mongoConfig.
But when wants to login it seems the problem is my mongouserdtailsservice.
Thanks
public class MongoUserDetailsService implements UserDetailsService
{
#Override
public UserDetails loadUserByUsername(String username) throws AuthenticationServiceException
{
MongoOperations mongoOperations = null;
try
{
mongoOperations = new MongoTemplate(new MongoClient(), "booking");
}
catch (UnknownHostException e)
{
e.printStackTrace();
}
catch (MongoException e)
{
e.printStackTrace();
}
try
{
Query query = new Query(Criteria.where("email").is(username));
System.out.println("query ready to go");
Customer customer = mongoOperations.findOne(query, Customer.class);
System.out.println("query done");
System.out.println("user: "+customer);
if (customer == null)
{
throw new AuthenticationServiceException("Authentication failed for user " + username);
}
boolean enabled = true;
boolean accountNonExpired = true;
boolean credentialsNonExpired = true;
boolean accountNonLocked = true;
return new User(customer.getUsername(), customer.getPassword().toLowerCase(), enabled, accountNonExpired, credentialsNonExpired, accountNonLocked,
getAuthorities(2));
}
catch (Exception e)
{
System.out.println("query failed");
throw new RuntimeException(e);
}
}

{
List<GrantedAuthority> authList = getGrantedAuthorities(getRoles(role));
return authList;
}

{

if (role.intValue() == 1)
{
roles.add("ROLE_USER");
roles.add("ROLE_ADMIN");
}
else if (role.intValue() == 2)
{
roles.add("ROLE_USER");
}
return roles;
}
public static List<GrantedAuthority> getGrantedAuthorities(List<String> roles)

Solved
It was a conflict in my MongoUserDetailsService.
Here is the new one which is working well!(OBS! The new log in is with email)
#Component
public class MongoUserDetailsService implements UserDetailsService
{
public MongoOperations mongoOperations;
private User userDetails;
#Override
public UserDetails loadUserByUsername(String email) throws UsernameNotFoundException
{
boolean enabled = true;
boolean accountNonLocked = true;
boolean accountNonExpired = true;
boolean credentialsNonExpired = true;
try
{
mongoOperations = new MongoTemplate(new MongoClient(), "booking");
Customer user = getUserByEmail(email);
userDetails = new User(user.getEmail(), user.getPassword(), enabled, accountNonExpired, credentialsNonExpired, accountNonLocked,
getAuthorities(user.getRoleAsInt()));
}
catch (UnknownHostException e)
{
e.printStackTrace();
}
return userDetails;
}
public List getAuthorities(Integer role)
{
List authList = new ArrayList();
if (role.intValue() == 2)
{
authList.add(new SimpleGrantedAuthority("ROLE_ADMIN"));
authList.add(new SimpleGrantedAuthority("ROLE_USER"));
}
if (role.intValue() == 1)
{
authList.add(new SimpleGrantedAuthority("ROLE_USER"));
}
return authList;
}
public Customer getUserByEmail(String email)
{
Query query = new Query();
query.addCriteria(Criteria.where("email").is(email));
Customer customer = mongoOperations.findOne(query, Customer.class);
return customer;
}
}
