Spring security part 2

Configure DB authentication instead of In memory authentication

Add Role entity, Dao and Service layer for it.

  public interface RoleService {
      Role add(Role role);
  
      Role getByName(String roleName);
  }

Configure role access to specific resources for ADMIN and for USER. You should configure access to all endpoints in your application. Example:

POST: /register - all
GET: /cinema-halls - user/admin
POST: /cinema-halls - admin
GET: /movies - user/admin
POST: /movies - admin
GET: /movie-sessions/available - user/admin
POST: /movie-sessions - admin
PUT: /movie-sessions/{id} - admin
DELETE: /movie-sessions/{id} - admin
GET: /orders - user
POST: /orders/complete - user
PUT: /shopping-carts/movie-sessions - user
GET: /shopping-carts/by-user - user
GET: /users/by-email - admin
...

HINT:

Let's store role names as enums and add enum RoleName inside Role class.
Roles and first Admin user can be injected inside DataInitializer class using annotation @PostConstruct.

@PostConstruct
public void inject() {
    Role adminRole = new Role();
    adminRole.setRoleName(Role.RoleName.ADMIN);
    roleService.add(adminRole);
    Role userRole = new Role();
    userRole.setRoleName(Role.RoleName.USER);
    roleService.add(userRole);
    User user = new User();
    user.setEmail("admin@i.ua");
    user.setPassword("admin123");
    user.setRoles(Set.of(adminRole));
    userService.add(user);
}

You can specify the different HTTP method access for the same endpoint. For example:

        protected void configure(HttpSecurity http) throws Exception {
        http
                .authorizeRequests()
                .antMatchers(HttpMethod.POST,"/movies/**").hasRole("ADMIN")
                .antMatchers(HttpMethod.GET,"/movies/**").permitAll()
                .anyRequest().authenticated()
                .and()
                .formLogin()
                .permitAll()
                .and()
                .httpBasic()
                .and()
                .csrf().disable();
    }
