Package org.springframework.integration.test.matcher

Class PayloadMatcher<T>

java.lang.Object
org.hamcrest.BaseMatcher<T>
org.hamcrest.TypeSafeMatcher<Message<?>>
org.springframework.integration.test.matcher.PayloadMatcher<T>
All Implemented Interfaces:
org.hamcrest.Matcher<Message<?>>, org.hamcrest.SelfDescribing
public final class PayloadMatcher<T> extends org.hamcrest.TypeSafeMatcher<Message<?>>
Is the payload of a Message equal to a given value or is matching a given matcher?

A Junit example using Assert.assertThat(Object, Matcher) could look like this to test a payload value: 

 
 ANY_PAYLOAD = new BigDecimal("1.123");
 Message<BigDecimal> message = MessageBuilder.withPayload(ANY_PAYLOAD).build();
 assertThat(message, hasPayload(ANY_PAYLOAD));

An example using Assert.assertThat(Object, Matcher) delegating to another Matcher. 

 
 ANY_PAYLOAD = new BigDecimal("1.123");
 Message<BigDecimal> message = MessageBuilder.withPayload(ANY_PAYLOAD).build();
 assertThat(message, PayloadMatcher.hasPayload(is(BigDecimal.class)));
 assertThat(message, PayloadMatcher.hasPayload(notNullValue()));
 assertThat(message, not((PayloadMatcher.hasPayload(is(String.class))))); *
