title: Spring Boot ignore ObjectMapper module
body: <p>In application context I have registered an ObjectMapper module:</p>
  
  <pre><code>@Bean
  public SimpleModule jsr310Module() {
      final SimpleModule module = new SimpleModule();
      module.addSerializer(new LocalDateSerializer());
      module.addDeserializer(LocalDate.class, new LocalDateDeserializer());
      return module;
  }
  </code></pre>
  
  <p>I tried to debug and it is loaded (or at least the method <code>public void setupModule(SetupContext context)</code> is execute on boot)
  but when I call a rest API that return an object with a LocalDate my deserializer is ignored.</p>
  
  <p>Some hint to solve the problem?</p>
