* Daten verarbeiten:
    * Angenommen, Sie erhalten eine Datei, die einen langsamen Prozess durchlaufen muss. Sie können als Response „Accepted“ (HTTP 202) zurückgeben und die Datei im Hintergrund verarbeiten.

## `BackgroundTasks` verwenden

            "The network name cannot be found.",
            "No more connections can be made to this remote computer at this time because there are already as many connections as the computer can accept.",
            "Indicates a Windows NT Server could not be contacted or that objects within the domain are protected such that necessary information could not be retrieved.",

* Procesamiento de datos:
  * Por ejemplo, supongamos que recibes un archivo que debe pasar por un proceso lento, puedes devolver un response de "Accepted" (HTTP 202) y procesar el archivo en segundo plano.

## Usando `BackgroundTasks`

Primero, importa `BackgroundTasks` y define un parámetro en tu *path operation function* con una declaración de tipo de `BackgroundTasks`:

        // Arrange
        jcifs.SID mockSid = mock(jcifs.SID.class);
        when(mockSid.unwrap(sid_t.class)).thenReturn(mockSidT);
        testSids = new jcifs.SID[] { mockSid };

        // Act & Assert - Constructor accepts null, no exception thrown
        assertDoesNotThrow(() -> {
            new MsrpcLookupSids(null, testSids);
        });
    }

    @Test
    void constructor_shouldThrowExceptionWithNullSids() {

            final int bufferSize, final Consumer<String> outputCallback) {
        final ProcessBuilder pb = new ProcessBuilder(cmdList);
        pbCall.accept(pb);
        destroyProcess(sessionId);
        JobProcess jobProcess;
        try {
            jobProcess = new JobProcess(pb.start(), bufferSize, outputCallback);

            searchLog.setClientIp("192.168.1.1");
            searchLog.setSearchWord("test");
            searchLog.setRequestedAt(LocalDateTime.now());
            searchLogList.add(searchLog);
            entityListLambda.accept(searchLogList);
        }
    }

    private static class MockElevateWordBhv extends ElevateWordBhv {
        public List<ElevateWord> selectList(Consumer<Object> cbLambda) {

        return doSelectEntity(xprepareCBAsPK(id), tp);
    }

    protected BadWordCB xprepareCBAsPK(String id) {
        assertObjectNotNull("id", id);
        return newConditionBean().acceptPK(id);
    }

    protected <ENTITY extends BadWord> OptionalEntity<ENTITY> doSelectOptionalByPK(String id, Class<? extends ENTITY> tp) {
        return createOptionalEntity(doSelectByPK(id, tp), id);
    }

        return doSelectEntity(xprepareCBAsPK(id), tp);
    }

    }

    protected <ENTITY extends BoostDocumentRule> OptionalEntity<ENTITY> doSelectOptionalByPK(String id, Class<? extends ENTITY> tp) {
        return createOptionalEntity(doSelectByPK(id, tp), id);
    }

        return doSelectEntity(xprepareCBAsPK(id), tp);
    }

    protected DuplicateHostCB xprepareCBAsPK(String id) {
        assertObjectNotNull("id", id);
        return newConditionBean().acceptPK(id);
    }

    protected <ENTITY extends DuplicateHost> OptionalEntity<ENTITY> doSelectOptionalByPK(String id, Class<? extends ENTITY> tp) {
        return createOptionalEntity(doSelectByPK(id, tp), id);
    }

        return doSelectEntity(xprepareCBAsPK(id), tp);
    }

    protected JobLogCB xprepareCBAsPK(String id) {
        assertObjectNotNull("id", id);
        return newConditionBean().acceptPK(id);
    }
