Seguridad con Spring Security

@Configuration
@EnableWebSecurity
public class SecurityConfig {

  @Bean
  public SecurityFilterChain securityChain(HttpSecurity http) throws Exception {
    return http
      .authorizeRequests(auth -> auth.anyRequest().authenticated())
      .formLogin(Customizer.withDefaults())
      .build();
  }

  @Bean
  public UserDetailsService users() {
    UserDetails user = User.builder()
      .username("user1")
      .password(passwordEncoder().encode("pass123"))
      .roles("ACTIVITI_USER")
      .build();
    return new InMemoryUserDetailsManager(user);
  }
  
  @Bean
  public PasswordEncoder passwordEncoder() {
    return new BCryptPasswordEncoder();
  }
}

Utilidad de Autenticación

@Component
public class AuthHelper {

  @Autowired
  private UserDetailsService userService;

  public void authenticateUser(String username) {
    UserDetails user = userService.loadUserByUsername(username);
    SecurityContextHolder.getContext().setAuthentication(
      new UsernamePasswordAuthenticationToken(user, null, user.getAuthorities())
    );
  }
}

Operaciones con API de Activiti

@Service
public class FlowService {

  @Autowired
  private ProcessRuntime processEngine;

  @Autowired
  private AuthHelper authUtil;

  public void startProcess(String processKey) {
    authUtil.authenticateUser("admin");
    processEngine.start(ProcessPayloadBuilder
      .start()
      .withProcessDefinitionKey(processKey)
      .build()
    );
  }

  public void completeTask(String taskId) {
    authUtil.authenticateUser("user1");
    taskRuntime.complete(TaskPayloadBuilder
      .complete()
      .withTaskId(taskId)
      .build()
    );
  }
}

Manejadores de Eventos

@Configuration
public class EventConfig {

  @Bean
  public ProcessRuntimeEventListener<ProcessCompletedEvent> onProcessComplete() {
    return event -> System.out.println("Proceso completado: " + event.getEntity().getId());
  }

  @Bean
  public TaskRuntimeEventListener<TaskCompletedEvent> onTaskComplete() {
    return event -> System.out.println("Tarea finalizada: " + event.getEntity().getName());
  }
}
