Examples with WireTap org.springframework.integration.channel.interceptor.WireTap used on opensource projects

Example 1 with WireTap

use of org.springframework.integration.channel.interceptor.WireTap in project spring-integration by spring-projects.

the class MessageChannelSpec method wireTap.

/**
 * Populate the {@code Wire Tap} EI Pattern specific
 * {@link org.springframework.messaging.support.ChannelInterceptor} implementation.
 * @param wireTapSpec the {@link WireTapSpec} to build {@link WireTap} instance.
 * @return the current {@link MessageChannelSpec}.
 * @see WireTap
 */
public S wireTap(WireTapSpec wireTapSpec) {
    WireTap interceptor = wireTapSpec.get();
    this.componentsToRegister.put(interceptor, null);
    return interceptor(interceptor);
}

Example 2 with WireTap

use of org.springframework.integration.channel.interceptor.WireTap in project spring-integration by spring-projects.

the class IntegrationFlowDefinition method wireTap.

/**
 * Populate the {@code Wire Tap} EI Pattern specific
 * {@link org.springframework.messaging.support.ChannelInterceptor} implementation
 * to the current {@link #currentMessageChannel}.
 * <p> It is useful when an implicit {@link MessageChannel} is used between endpoints:
 * <pre class="code">
 * {@code
 *  .transform("payload")
 *  .wireTap(new WireTap(tapChannel().selector(m -> m.getPayload().equals("foo")))
 *  .channel("foo")
 * }
 * </pre>
 * This method can be used after any {@link #channel} for explicit {@link MessageChannel},
 * but with the caution do not impact existing {@link org.springframework.messaging.support.ChannelInterceptor}s.
 * @param wireTapSpec the {@link WireTapSpec} to use.
 * <p> When this EIP-method is used in the end of flow, it appends {@code nullChannel} to terminate flow properly,
 * Otherwise {@code Dispatcher has no subscribers} exception is thrown for implicit {@link DirectChannel}.
 * @return the current {@link IntegrationFlowDefinition}.
