title: Write-only properties with Jackson
body: <p>In my entity class, I'm trying to make a write-only field (gets ignored during serialization, but gets de-serialized normally).</p>
  
  <pre><code>@JsonProperty
  @JsonSerialize(using=NullSerializer.class)
  public String getPassword() {
      return password;
  }
  </code></pre>
  
  <p>This <em>almost</em> gives me what I want: the JSON contains the "password" field, but the value is always null. How do I remove the field entirely?</p>
