Jackson OffsetDateTime 序列化 Z 而不是 +00:00 时区？

我将 Spring Boot 与以下 ObjectMapper 一起使用：

@Bean
public ObjectMapper objectMapper()
{
    final ObjectMapper mapper = new ObjectMapper();

    mapper.enable(SerializationFeature.INDENT_OUTPUT);

    mapper.disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS);  
    mapper.setDateFormat(new StdDateFormat().withColonInTimeZone(true)); // Makes no difference to output

    mapper.findAndRegisterModules();

    return mapper;
}

当 OffsetDateTimes 被序列化并在响应中返回时，它们的格式如下：

"2020-02-28T12:28:29.01Z"
"2020-02-28T12:36:21.885Z"

我本来希望最后的时区信息看起来像这样：

"2020-02-28T10:41:25.287+00:00"

我在这里遗漏或做错了什么，或者无论如何我可以将时区信息序列化为+00:00格式而不是885Z格式？

非常感谢！
