Jackson - Serialize ZonedDateTime to ISO 8601 String

I want to serialize a ZonedDateTime to an ISO 8601 compliant String, e.g.:
2018-02-14T01:01:02.074+0100.

I tried the following:

@JsonProperty("@timestamp")
@JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd'T'HH:mm:ss.SSSXXX")
private ZonedDateTime timestamp;

But unfortunately it does not give the correct result and serializes the ZonedDateTime with all its fields, etc.

Thank you already for your help!

Make sure you include and register the Jackson module for date and time classes introduced in Java 8. E.g.

<dependency>
    <groupId>com.fasterxml.jackson.datatype</groupId>
    <artifactId>jackson-datatype-jsr310</artifactId>
    <version>2.8.10</version>
</dependency>

and if necessary:

ObjectMapper mapper = new ObjectMapper();
mapper.registerModule(new JavaTimeModule());

Side note: You may also achieve the desired format without the annotation and just configuring ObjectMapper to not serialize date as timestamp. E.g.

mapper.disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS);
