Usage

From source file:org.springframework.integration.endpoint.PseudoTransactionalMessageSourceTests.java

@Test
public void testInt2777UnboundResourceAfterTransactionComplete() {
    SourcePollingChannelAdapter adapter = new SourcePollingChannelAdapter();

    adapter.setSource(() -> null);

    TransactionSynchronizationManager.setActualTransactionActive(true);
    doPoll(adapter);/*from   w w  w.j  a  v a 2s. c  o m*/
    TransactionSynchronizationManager.setActualTransactionActive(false);

    // Before INT-2777 this test was failed here
    TransactionSynchronizationManager.setActualTransactionActive(true);
    doPoll(adapter);
