Roles not getting fetched from database along with the user object - spring-boot

Question

I am creating a user registration flow with spring boot (2.1.3.RELEASE) . With the help of few articles I am able to successfully add a user along with its roles and user is able to login into the system. The problem is when user is successfully loged-in, the authentication obect has empty role even when I can see th correct role mapping in mysql database (honestly I am not able to get exactly how roles are fetched from database when findByUserName method is called.
Below is my code:
Entity objects
1. User.java
public class User implements UserDetails {
private static final long serialVersionUID = 1L;
public User() {
//Verification flow 2. set enabled = false
this.enabled = false;
}
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Column(name = "user_unique_number")
private long id;
#UniqueUser(groups = UniqueUserOrder.class)
#Column(name = "username", length = 60,nullable = false, unique = true)
private String username;
#Column(name = "email", nullable = false, unique = true)
private String email;
#Column(name = "password", nullable = false)
private String password;
#OneToMany(mappedBy = "user", cascade = CascadeType.ALL, fetch = FetchType.EAGER)
private Set<UserRole> userRoles = new HashSet<>();
#Override
public Collection<? extends GrantedAuthority> getAuthorities() {
Set<GrantedAuthority> authorities = new HashSet<>();
userRoles.forEach(ur -> authorities.add(new Authority(ur.getRole().getName())));
return authorities;
}
public Set<UserRole> getUserRoles() {
return userRoles;
}
public void setUserRoles(Set<UserRole> userRoles) {
this.userRoles = userRoles;
}
...//OTHER GETTERS AND SETTERS
}
Roles.java
public class Role
{#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Column(name = "id")
private int id;
private String name;
#OneToMany(mappedBy = "role", cascade = CascadeType.ALL, fetch = FetchType.LAZY)
private Set<UserRole> userRoles = new HashSet<>();
public Role() {
}
public Role(RolesEnum rolesEnum) {
this.id = rolesEnum.getId();
this.name = rolesEnum.getRoleName();
}
public Set<UserRole> getUserRoles() {
return userRoles;
}
public void setUserRoles(Set<UserRole> userRoles) {
this.userRoles = userRoles;
}
...//OTHER GETTERS AND SETTERS }
UserRole.java
public class UserRole {
public UserRole() {}
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Column(name = "id")
private long id;
public UserRole(User user, Role role) {
this.user = user;
this.role = role;
}
#ManyToOne(fetch = FetchType.EAGER)
#JoinColumn(name = "user_id")
private User user;
#ManyToOne(fetch = FetchType.EAGER)
#JoinColumn(name = "role_id")
private Role role;
...//OTHER GETTERS AND SETTERS
}
4.RolesEnum.java
public enum RolesEnum {
ADMIN(1, "ROLE_ADMIN"),
BASIC(2, "ROLE_BASIC");
private final int id;
private final String roleName;
...//OTHER GETTERS AND SETTERS
}
New user is getting created as below:
...
...
String encryptedPassword = passwordEncoder.encode(adminPassword);
user.setPassword(encryptedPassword);
user.setUsername(adminUsername);
user.setEmail(adminEmail);
user.setUserCreateTime(LocalDateTime.now());
Set<UserRole> userRoles = new HashSet<>();
UserRole userRole = new UserRole();
userRole.setUser(user);
userRole.setRole(new Role(RolesEnum.ADMIN));
userRoles.add(userRole);
user.getUserRoles().addAll(userRoles);
user.setAccountNonLocked(true);
user.setEnabled(true);
user.setAccountNonExpired(true);
user.setCredentialsNonExpired(true);
user = userRepository.save(user);
...
...
At this point user is added successfully along with the roles in database
User is also able to successfully log-in but the problem is after logging, authentication object has an empty list of roles
Below is the code which is failing
public class SecurityConfig extends WebSecurityConfigurerAdapter {
......
......
private AuthenticationSuccessHandler loginSuccessHandler() {
return (request, response, **authentication**) -> {
Collection<? extends GrantedAuthority> authorities
= authentication.getAuthorities();
for (GrantedAuthority grantedAuthority : authorities) {
if (grantedAuthority.getAuthority().equals("ROLE_ADMIN")) {
isAdmin = true;
break;
} else if (grantedAuthority.getAuthority().equals("ROLE_ADMIN")) {
isBasic = true;
break;
}
}
if (isAdmin) { return "/admin/"; } else if (isBasic) { return
"/profile.html"; } else { throw new IllegalStateException(); }
response.sendRedirect("/");
};
}
......
......
When i inspect authentication object using eclipse the roles are not getting fetched from database
Here is the code for fetching user#Override
public User findByUserName(String username) {
return userRepository.findByUsername(username);
}
Do I need to add some additional logic to fetch roles along with user or Spring handles it behind the scene? Please let me know what I am doing wrong here... Thanks
