<h2>A step back</h2>

I'm particularly curious to know why you are using <a href="https://docs.oracle.com/javase/8/docs/api/java/time/LocalDateTime.html" rel="noreferrer"><code>LocalDateTime</code></a> along with <a href="https://docs.oracle.com/javase/8/docs/api/java/time/ZoneId.html" rel="noreferrer"><code>ZoneId</code></a>. Wouldn't it be easier to use only <a href="https://docs.oracle.com/javase/8/docs/api/java/time/ZonedDateTime.html" rel="noreferrer"><code>ZonedDateTime</code></a>?

In terms of design, <a href="https://docs.oracle.com/javase/8/docs/api/java/time/ZonedDateTime.html" rel="noreferrer"><code>ZonedDateTime</code></a> is a combination of a <a href="https://docs.oracle.com/javase/8/docs/api/java/time/LocalDateTime.html" rel="noreferrer"><code>LocalDateTime</code></a> and a <a href="https://docs.oracle.com/javase/8/docs/api/java/time/ZoneId.html" rel="noreferrer"><code>ZoneId</code></a>. 

<h2>Supporting <code>ZoneId</code></h2>

Assuming that you still want to use <a href="https://docs.oracle.com/javase/8/docs/api/java/time/ZoneId.html" rel="noreferrer"><code>ZoneId</code></a>, you can write your own custom (de)serializer.

Alternatively, you can add the <a href="https://mvnrepository.com/artifact/com.fasterxml.jackson.datatype/jackson-datatype-jsr310" rel="noreferrer"><code>jackson-datatype-jsr310</code></a> artifact to your dependencies:

<pre class="lang-xml prettyprint-override"><code>&lt;dependency&gt;
 &lt;groupId&gt;com.fasterxml.jackson.datatype&lt;/groupId&gt;
 &lt;artifactId&gt;jackson-datatype-jsr310&lt;/artifactId&gt;
 &lt;version&gt;2.9&lt;/version&gt;
&lt;/dependency&gt;
</code></pre>

And then register the <a href="http://fasterxml.github.io/jackson-datatype-jsr310/javadoc/2.8/com/fasterxml/jackson/datatype/jsr310/JavaTimeModule.html" rel="noreferrer"><code>JavaTimeModule</code></a> module in your <code>ObjectMapper</code>:

<pre class="lang-java prettyprint-override"><code>ObjectMapper mapper = new ObjectMapper();
mapper.registerModule(new JavaTimeModule());
</code></pre>

In a Spring Boot application, you need the following:

<pre class="lang-java prettyprint-override"><code>@Configuration
public class JacksonConfig {

 @Bean
 public ObjectMapper createObjectMapper() { 
 ObjectMapper mapper = new ObjectMapper();
 mapper.registerModule(new JavaTimeModule());
 mapper.disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS);
 return mapper;
 }
}
</code></pre>

<a href="https://docs.oracle.com/javase/8/docs/api/java/time/ZoneId.html" rel="noreferrer"><code>ZoneId</code></a> is supported according to the <a href="https://github.com/FasterXML/jackson-modules-java8/tree/master/datetime" rel="noreferrer">documentation</a>:

<blockquote>
 <ul>
 <li><code>ZoneId</code> and <code>ZoneOffset</code>, which do not actually store dates and times but are supported with this module nonetheless.</li>
 </ul>
</blockquote>

<pre><code>@JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd'T'HH:mm:ss.SSS")
private LocalDateTime accessStart;

private ZoneId accessStartZoneId;
</code></pre>

Is there a built-in pattern mapper in Jackson to map JSON request containing a java <code>ZoneId</code>?

<pre><code>{
 "accessStart": "2017-10-10T10:10:10.100",
 "accessStartZoneID": "Australia/Sydney"
}
</code></pre>

I'm using Spring Boot 1.5.4.RELEASE. How to configure the deserializer for <code>ZoneId</code>? It works well with <code>accessStart</code>

<blockquote>
 JSON parse error: Can not construct instance of java.time.ZoneId: abstract types either need to be mapped to concrete types, have custom deserializer, or contain additional type information
</blockquote>
