java config中的MongoUserDetailsS​​ervice返回null

Question

任何人都可以看到为什么我在退回客户时会得到空？ 我正在使用java配置，并且能够通过我的mongoConfig连接到数据库。

但是当想要登录时，似乎问题是我的mongouserdtailsservice。

谢谢

   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);
    }
  }
  public Collection<? extends GrantedAuthority> getAuthorities(Integer role)
  {
    List<GrantedAuthority> authList = getGrantedAuthorities(getRoles(role));
    return authList;
    }

   public List<String> getRoles(Integer role)
  {
    List<String> roles = new ArrayList<String>();

    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)
    {
     List<GrantedAuthority> authorities = new ArrayList<GrantedAuthority>();
     for (String role : roles)
    {
        authorities.add(new SimpleGrantedAuthority(role));
    }
    return authorities;
   }


   }

解决

这是我的MongoUserDetailsS​​ervice中的冲突。

这是一个运作良好的新版本！（OBS！新登录是通过电子邮件发送的）

@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;
    }

}
