I have a design issue that I don't know how to solve. I'm using Spring 3.2.4 and Spring security 3.1.4.
I have a Account table in my database that looks like this:
create table Account (id identity,
username varchar unique,
password varchar not null,
firstName varchar not null,
lastName varchar not null,
university varchar not null,
primary key (id));
Until recently my username was just only a username but I changed it to be the email address instead since many users want to login with that instead.
I have a header that I include on all my pages which got a link to the users profile like this:
<a href="/project/users/<%= request.getUserPrincipal().getName()%>" class="navbar-link"><strong><%= request.getUserPrincipal().getName()%></strong></a>
The problem is that <%= request.getUserPrincipal().getName()%> returns the email now, I don't want to link the user's with thier emails. Instead I want to use the id every user have to link to the profile.
How do I reach the users id's from every page?
I have been thinking of two solutions but I'm not sure:
Change the principal to contain the id as well, don't know how to do this and having problem finding good information on the topic.
Add a model attribute to all my controllers that contain the whole user but this would be really ugly, like this.
Account account = entityManager.find(Account.class, email);
model.addAttribute("account", account);
There are more way's as well and I have no clue which one is to prefer.
I hope it's clear enough and thank you for any help on this.
====== Edit according to answer =======
I edited Account to implement UserDetails, it now looks like this (will fix the auto generated stuff later):
@Entity
@Table(name="Account")
public class Account implements UserDetails {
@Id
private int id;
private String username;
private String password;
private String firstName;
private String lastName;
@ManyToOne
private University university;
public Account() {
}
public Account(String username, String password, String firstName, String lastName, University university) {
this.username = username;
this.password = password;
this.firstName = firstName;
this.lastName = lastName;
this.university = university;
}
public String getUsername() {
return username;
}
public String getPassword() {
return password;
}
public String getFirstName() {
return firstName;
}
public String getLastName() {
return lastName;
}
public void setUsername(String username) {
this.username = username;
}
public void setPassword(String password) {
this.password = password;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
public University getUniversity() {
return university;
}
public void setUniversity(University university) {
this.university = university;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
@Override
public Collection<? extends GrantedAuthority> getAuthorities() {
// TODO Auto-generated method stub
return null;
}
@Override
public boolean isAccountNonExpired() {
// TODO Auto-generated method stub
return false;
}
@Override
public boolean isAccountNonLocked() {
// TODO Auto-generated method stub
return false;
}
@Override
public boolean isCredentialsNonExpired() {
// TODO Auto-generated method stub
return false;
}
@Override
public boolean isEnabled() {
// TODO Auto-generated method stub
return true;
}
}
I also added
<%@ taglib prefix="sec" uri="http://www.springframework.org/security/tags" %>
To my jsp files and trying to reach the id by
<sec:authentication property="principal.id" />
This gives me the following
org.springframework.beans.NotReadablePropertyException: Invalid property 'principal.id' of bean class [org.springframework.security.authentication.UsernamePasswordAuthenticationToken]: Bean property 'principal.id' is not readable or has an invalid getter method: Does the return type of the getter match the parameter type of the setter?
====== Edit 2 according to answer =======
I based my application on spring social samples and I never had to change anything until now.
This are the files I think are relevant, please tell me if theres something you need to see besides this.
AccountRepository.java
public interface AccountRepository {
void createAccount(Account account) throws UsernameAlreadyInUseException;
Account findAccountByUsername(String username);
}
JdbcAccountRepository.java
@Repository
public class JdbcAccountRepository implements AccountRepository {
private final JdbcTemplate jdbcTemplate;
private final PasswordEncoder passwordEncoder;
@Inject
public JdbcAccountRepository(JdbcTemplate jdbcTemplate, PasswordEncoder passwordEncoder) {
this.jdbcTemplate = jdbcTemplate;
this.passwordEncoder = passwordEncoder;
}
@Transactional
public void createAccount(Account user) throws UsernameAlreadyInUseException {
try {
jdbcTemplate.update(
"insert into Account (firstName, lastName, username, university, password) values (?, ?, ?, ?, ?)",
user.getFirstName(), user.getLastName(), user.getUsername(), user.getUniversity(),
passwordEncoder.encode(user.getPassword()));
} catch (DuplicateKeyException e) {
throw new UsernameAlreadyInUseException(user.getUsername());
}
}
public Account findAccountByUsername(String username) {
return jdbcTemplate.queryForObject("select username, firstName, lastName, university from Account where username = ?",
new RowMapper<Account>() {
public Account mapRow(ResultSet rs, int rowNum) throws SQLException {
return new Account(rs.getString("username"), null, rs.getString("firstName"), rs.getString("lastName"), new University("test"));
}
}, username);
}
}

And this is my try of implementing a UserDetailsService
public class RepositoryUserDetailsService implements UserDetailsService {
private final AccountRepository accountRepository;
@Autowired
public RepositoryUserDetailsService(AccountRepository repository) {
this.accountRepository = repository;
}
@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
Account user = accountRepository.findAccountByUsername(username);
if (user == null) {
throw new UsernameNotFoundException("No user found with username: " + username);
}
return user;
}
}
Still gives me the same error, do I need to add the UserDetailsService somewhere?
This is starting to be something else compared to my initial question, I should maybe start another question.
Sorry for my lack of experience in this. I have to read up.
