Spring Security/Spring Boot - How to set ROLES for users

Question

When I logged in using security, I cannot use the request.isUserInRole() method. I think the roles of the users was not set.

This is my Security Configurati

You should fill in the content of role by yourself when creating your UserDetails:

public class SecurityUser implements UserDetails{
    String ROLE_PREFIX = "ROLE_";

    String userName;
    String password;
    String role;

    public SecurityUser(String username, String password, String role){
        this.userName = username;
        this.password = password;
        this.role = role;
    }

    @Override
    public Collection<? extends GrantedAuthority> getAuthorities() {
        List<GrantedAuthority> list = new ArrayList<GrantedAuthority>();

        list.add(new SimpleGrantedAuthority(ROLE_PREFIX + role));

        return list;
    }

Basically, what you need to do is override method: getAuthorities, and fill in the content of your role field into the GrantedAuthority list.

What Divelnto, zapl and thorinkor said is right. But the question should be about "Role" and NOT "Roles". OR, if you are having users and roles into one table, its a bad design. You might want to take a relook at your design approach. You should have a separate role entity. And in your UserService you can do something like:

AppUser user = userRepository.findByUsername(username);

Set<GrantedAuthority> grantedAuthorities = new HashSet<>(); // use list if you wish
for (AppRole role : user.getRoles()) {
    grantedAuthorities.add(new SimpleGrantedAuthority(role.getName()));
}
return new org.springframework.security.core.userdetails.User(
        user.getUsername(),
        user.getPassword(),
        grantedAuthorities
);

In DB, you can store role name as - (e.g.) ADMIN/EDITOR/VIEWER in the database or store roles as ROLE_ADMIN/ROLE_... then you might wanna use hasRole/hasAuthoriy. Hope it helps.

For adding Roles you need to have a table containing username and its corresponding role.
Suppose a user has two roles namely, ADMIN and USER

One User can have multiple roles.

@Override
public Collection<? extends GrantedAuthority> getAuthorities() {
    final List<SimpleGrantedAuthority> authorities = new LinkedList<>();
    if (enabled) {
        if (this.getUser().isAdmin()) {
            authorities.add(new SimpleGrantedAuthority("ROLE_ADMIN"));
        }
        authorities.add(new SimpleGrantedAuthority("ROLE_USER"));
    }
        return authorities;
}

This can be called as,

private UsernamePasswordAuthenticationToken getAuthentication(
final String token, final HttpServletRequest req,
final HttpServletResponse res){
    return new UsernamePasswordAuthenticationToken(userAccount, null,
    userAccount.getAuthorities());
}
