title: How to serialize LocalDateTime with Jackson?
body: <p>I got the following piece of code:</p>
  
  <pre><code>    ObjectMapper mapper = new ObjectMapper();
      mapper.registerModule(new JavaTimeModule());
      mapper.disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS);
      String now = new ObjectMapper().writeValueAsString(new SomeClass(LocalDateTime.now()));
      System.out.println(now);
  </code></pre>
  
  <p>And I get this:</p>
  
  <blockquote>
    <p>{"time":{"hour":20,"minute":49,"second":42,"nano":99000000,"dayOfYear":19,"dayOfWeek":"THURSDAY","month":"JANUARY","dayOfMonth":19,"year":2017,"monthValue":1,"chronology":{"id":"ISO","calendarType":"iso8601"}}}</p>
  </blockquote>
  
  <p>What I want to achieve is a string in ISO8601</p>
