Example 51 with MessageHeaders

use of org.springframework.messaging.MessageHeaders in project spring-framework by spring-projects.

the class MappingJackson2MessageConverterTests method toMessageJsonView.

@Test
public void toMessageJsonView() throws Exception {
    MappingJackson2MessageConverter converter = new MappingJackson2MessageConverter();
    Map<String, Object> map = new HashMap<>();
    Method method = getClass().getDeclaredMethod("jsonViewResponse");
    MethodParameter returnType = new MethodParameter(method, -1);
    Message<?> message = converter.toMessage(jsonViewResponse(), new MessageHeaders(map), returnType);
    String actual = new String((byte[]) message.getPayload(), StandardCharsets.UTF_8);
    assertThat(actual, containsString("\"withView1\":\"with\""));
    assertThat(actual, containsString("\"withView2\":\"with\""));
    assertThat(actual, not(containsString("\"withoutView\":\"with\"")));
    method = getClass().getDeclaredMethod("jsonViewPayload", JacksonViewBean.class);
    MethodParameter param = new MethodParameter(method, 0);
    JacksonViewBean back = (JacksonViewBean) converter.fromMessage(message, JacksonViewBean.class, param);
    assertNull(back.getWithView1());
    assertEquals("with", back.getWithView2());
    assertNull(back.getWithoutView());
}
