Em seguida, usamos `hero_db.sqlmodel_update(hero_data)` para atualizar o `hero_db` com os dados de `hero_data`.

**Template Method**: `AbstractCrawlerClient`, `AbstractExtractor` - common logic with overrides
**DI**: LastaFlute container with `@Resource` and XML config

### Core Principles

**Thread Safety**:
- `AtomicLong` for counters (`CrawlerContext.accessCount`)
- `volatile` for status flags
- Synchronized blocks for critical sections
- Thread-local storage via `CrawlingParameterUtil`

Para OAuth2 son solo strings.

Primero, echemos un vistazo rápido a las partes que cambian desde los ejemplos en el **Tutorial - User Guide** principal para [OAuth2 con Password (y hashing), Bearer con tokens JWT](../../tutorial/security/oauth2-jwt.md){.internal-link target=_blank}. Ahora usando scopes de OAuth2:

    elementsPlus.add(AFTER_LAST_2);
    return Ordering.explicit(new ArrayList<>(elementsPlus));
  }

  /*
   * All the ContiguousSet generators below manually reject nulls here. In principle, we'd like to
   * defer that to Range, since it's ContiguousSet.create() that's used to create the sets. However,
   * that gets messy here, and we already have null tests for Range.
   */

  /*

     * @param providerUrl The provider URL.
     * @param principal The principal.
     * @param credntials The credentials.
     * @return The environment for LDAP connection.

            final String providerUrl, final String principal, final String credntials) {

Where the spec is ambiguous, OkHttp follows modern user agents such as popular Browsers or common HTTP Libraries.

OkHttp is principled and avoids being overly configurable, especially when such configuration is
to workaround a buggy server, test invalid scenarios or that contradict the relevant RFC.

* E também poderia ter uma declaração da resposta que deveria retornar, por exemplo, `response_model=InvoiceEventReceived`.

Há 2 diferenças principais de uma *operação de rota* normal:

* Ela não necessita ter nenhum código real, porque seu aplicativo nunca chamará esse código. Ele é usado apenas para documentar a *API externa*. Então, a função poderia ter apenas `pass`.
