Class HeaderMatcher

java.lang.Object

org.hamcrest.BaseMatcher<T>

org.springframework.integration.test.matcher.HeaderMatcher

All Implemented Interfaces:

org.hamcrest.Matcher<Message<?>>, org.hamcrest.SelfDescribing

public class HeaderMatcher
extends org.hamcrest.BaseMatcher<T>

Are the MessageHeaders of a Message containing any entry or multiple that match?

For example using Assert.assertThat(Object, Matcher) for a single entry:

 ANY_HEADER_KEY = "foo";
 ANY_HEADER_VALUE = "bar";
 assertThat(message, hasEntry(ANY_HEADER_KEY, ANY_HEADER_VALUE));
 assertThat(message, hasEntry(ANY_HEADER_KEY, is(String.class)));
 assertThat(message, hasEntry(ANY_HEADER_KEY, notNullValue()));
 assertThat(message, hasEntry(ANY_HEADER_KEY, is(ANY_HEADER_VALUE)));
 
 

For multiple entries to match all:

 Map<String, Object> expectedInHeaderMap = new HashMap<String, Object>();
 expectedInHeaderMap.put(ANY_HEADER_KEY, ANY_HEADER_VALUE);
 expectedInHeaderMap.put(OTHER_HEADER_KEY, is(OTHER_HEADER_VALUE));
 assertThat(message, HeaderMatcher.hasAllEntries(expectedInHeaderMap));
 
 

For a single key:

 ANY_HEADER_KEY = "foo";
 assertThat(message, HeaderMatcher.hasKey(ANY_HEADER_KEY));

Method Detail

matchesSafely

public boolean matchesSafely(Message<?> item)

Subclasses should implement this. The item will already have been checked for the specific type and will never be null.

Parameters:

item - The item.

Returns:

true if matches.

hasExpirationDate

public static org.hamcrest.Matcher<Message<?>> hasExpirationDate(org.hamcrest.Matcher<Long> matcher)

hasTimestamp

matches

public final boolean matches(Object item)

Method made final to prevent accidental override. If you need to override this, there's no point on extending TypeSafeMatcher. Instead, extend the BaseMatcher.
