    Foo foo = new Foo();
    foo.setName("Bill");
    Message<?> message = MessageBuilder.withPayload(foo).setHeader(MessageHeaders.CONTENT_TYPE, MessageConverterUtils.X_JAVA_OBJECT).build();

    binderBindUnbindLatency();
    CountDownLatch latch = new CountDownLatch(1);

    moduleInputChannel.subscribe(message1 -> {

        } finally {
            latch.countDown();

    moduleOutputChannel.send(message);
    Assert.isTrue(latch.await(5, TimeUnit.SECONDS), "Failed to receive message");
    KryoMessageConverter kryo = new KryoMessageConverter(null, true);
    Foo fooPayload = (Foo) kryo.fromMessage(inboundMessageRef.get(), Foo.class);
    assertNotNull(fooPayload);
    assertThat(inboundMessageRef.get().getHeaders().get(BinderHeaders.BINDER_ORIGINAL_CONTENT_TYPE)).isNull();
    producerBinding.unbind();
    consumerBinding.unbind();
}

Example 2 with KryoMessageConverter

    assertNotNull(outputMessage);
    MimeType contentType = (MimeType) outputMessage.getHeaders().get(MessageHeaders.CONTENT_TYPE);
    assertEquals("x-java-object", contentType.getSubtype());
}

Example 3 with KryoMessageConverter
