@Test
public void sendOnlyViewExpression() throws Exception {
    QueueChannel requestChannel = new QueueChannel();
    HttpRequestHandlingController controller = new HttpRequestHandlingController(false);
    controller.setBeanFactory(mock(BeanFactory.class));
    controller.setRequestChannel(requestChannel);
    Expression viewExpression = new SpelExpressionParser().parseExpression("'baz'");
    controller.setViewExpression(viewExpression);
    controller.afterPropertiesSet();//from w  w w. jav  a 2  s.  co  m
    controller.start();

    MockHttpServletRequest request = new MockHttpServletRequest();
    request.setMethod("POST");
    request.setContent("hello".getBytes());

    //request.setContentType("text/plain"); //Works in Spring 3.1.2.RELEASE but NOT in 3.0.7.RELEASE
    //Instead do:
    request.addHeader("Content-Type", "text/plain");

    MockHttpServletResponse response = new MockHttpServletResponse();
    ModelAndView modelAndView = controller.handleRequest(request, response);
    assertEquals("baz", modelAndView.getViewName());
    assertEquals(0, modelAndView.getModel().size());
    Message<?> requestMessage = requestChannel.receive(0);
    assertNotNull(requestMessage);
    assertEquals("hello", requestMessage.getPayload());
