FasterXML中存在无法识别的PropertyException

当我使用fasterXML将字符串"{"name":"John","timestamp":"2020-08-14T11:47:52.297194Z"}"转换为POJO时，我读取了它，得到了以下异常

com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: Unrecognized field "timestamp" (class com.job.model.Person), not marked as ignorable (2 known properties:  "name", "timeStamp"])

我的POJO是

@Data
@NoArgsConstructor
@Table(keyspace = "keyspace", name = "testTable")
public class Person implements Serializable {
private static final long serialVersionUID = 1L;

@Column(name = "name")
private String name;

@Column(name = "timeStamp")
//@JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss", timezone = "UTC") // Tried with this no luck.
private Instant timeStamp; 
}

我从下面的url添加了所需的依赖项，

https://github.com/FasterXML/jackson-modules-java8，以及

<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.11.0</version>
</dependency>

ObjectMapper objectMapper = JsonMapper.builder()
.addModule(new ParameterNamesModule())
.addModule(new Jdk8Module())
.addModule(new JavaTimeModule())
.build();
