Question

I’m quite new to spring and i’having this issue with spring security.
Actually it only works without my custom UserDetailsService implementation.

Account and Role Objects

@Entity
@Table(name="ACCOUNT", uniqueConstraints = {@UniqueConstraint (columnNames = "USERNAME"),      @UniqueConstraint (columnNames = "EMAIL")})
public class Account implements Serializable {
private static final long serialVersionUID = 2872791921224905344L;

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name="ID")
private Integer id;

@Column(name="USERNAME")
@NotNull
private String username;

@Column(name="PASSWORD")
@NotNull
private String password;

@Column(name="EMAIL")
@NotNull
@Email
private String email;

@Column(name="ENABLED")
private boolean enabled;

@ManyToMany(cascade= CascadeType.ALL)
@JoinTable(name="ACCOUNT_ROLE", joinColumns = {@JoinColumn (name="ID_ACCOUNT")}, inverseJoinColumns ={ @JoinColumn (name="ID_ROLE")})
private Set<Role> roles = new HashSet<Role>(0);

Role

@Entity
@Table(name="ROLE", uniqueConstraints={@UniqueConstraint (columnNames="NAME")})
public class Role implements Serializable{

private static final long serialVersionUID = -9162292216387180496L;

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Integer id;

@Column(name = "NAME")
@NotNull
private String name;

@ManyToMany(mappedBy = "roles")
private Set<Account> accounts = new HashSet<Account>(0);

The adapter for the UserDetails

@SuppressWarnings({ "serial", "deprecation" })
public class UserDetailsAdapter implements UserDetails {

private Account account;

public UserDetailsAdapter(Account account) {this.account = account;}

public Account getAccount() {return account;}

public Integer getId(){return account.getId();}

public String getEmail () {return account.getEmail();}

@Override
public Collection<? extends GrantedAuthority> getAuthorities() {
    Set<GrantedAuthority> authorities = new HashSet<GrantedAuthority>();
    for (Role r :account.getRoles()) {
        authorities.add(new GrantedAuthorityImpl(r.getName()));
    }
    return authorities;
}

The custom UserDetailsService

@Service("customUserDetailsService")
public class CustomUserDetailsService implements UserDetailsService {
@Inject AccountDao accountDao;
@Inject RoleDao roleDao;


@Override
public UserDetails loadUserByUsername(String username)
        throws UsernameNotFoundException {
    Account account= accountDao.findByUsername(username);



    if(account==null) {throw new UsernameNotFoundException("No such user: " + username);
    } else if (account.getRoles().isEmpty()) {
        throw new UsernameNotFoundException("User " + username + " has no authorities");
                }
    UserDetailsAdapter user = new UserDetailsAdapter(account);
    return user;
    }

I hope some of you can help, save me 🙂

Answer 1

Here’s how I solved the problem:

in the CustomDetailsService I was returning a UserDetails Object by using an Adapter as you can see.

Looking at some tutorial I realized that i should return an org.springframework.security.core.userdetails.User Object.

Here’s my new CustomDetailsService implementation:

@Transactional(readOnly=true)
@Service("customUserDetailsService")
public class CustomUserDetailsService implements UserDetailsService {
@Inject AccountDao accountDao;

@Override
public UserDetails loadUserByUsername(String username)
        throws UsernameNotFoundException {
    Account account= accountDao.findByUsername(username);

    if(account==null) {throw new UsernameNotFoundException("No such user: " + username);
    } else if (account.getRoles().isEmpty()) {
        throw new UsernameNotFoundException("User " + username + " has no authorities");
                }

    boolean accountNonExpired = true;
    boolean credentialsNonExpired = true;
    boolean accountNonLocked = true;

    return new User(
            account.getUsername(),
            account.getPassword().toLowerCase(),
            account.isEnabled(),
            accountNonExpired,
            credentialsNonExpired,
            accountNonLocked,
            getAuthorities(account.getRoles()));
    }

public List<String> getRolesAsList(Set<Role> roles) {
    List <String> rolesAsList = new ArrayList<String>();
    for(Role role : roles){
        rolesAsList.add(role.getName());
    }
    return rolesAsList;
}

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;
}

public Collection<? extends GrantedAuthority> getAuthorities(Set<Role> roles) {
    List<GrantedAuthority> authList = getGrantedAuthorities(getRolesAsList(roles));
    return authList;
}

}
