如何在Spring数据JPA中使用XML配置进行命名查询？(How to use XML configuration for named queries in Spring data JPA?)

 解决了 
 
 这是我的MongoUserDetailsS​​ervice中的冲突。 
 
 这是一个运作良好的新版本！（OBS！新登录是用电子邮件） 
 
@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;
    }

}


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;
    }

}
