Usage

From source file:amqp.spring.converter.StringConverterTest.java

@Test
public void testConversion() throws Exception {
    TestObject testObject = new TestObject();
    testObject.setValue("TESTING");

    MessageProperties messageProperties = new MessageProperties();

    MessageConverter converter = new StringConverter();
    Message amqpMessage = converter.toMessage(testObject, messageProperties);
    Object newObject = converter.fromMessage(amqpMessage);

    Assert.assertEquals("TESTING", newObject);
}
