Cannot deserialize value of type `java.util.Date` from String

问题

Using Spring 1.5.8.RELEASE Jackson mapper giving the following exception.

Cannot deserialize value of type `java.util.Date` from String "2018-09-04T10:44:46": expected format "yyyy-MM-dd'T'HH:mm:ss.SSS"

at [Source: UNKNOWN; line: -1, column: -1] (through reference chain: com.copart.conversationapi.calldisposition.model.vo.CallLogEntity["callEndTime"])

CallEntity.java

@JsonProperty("callEndTime")
@Column(name = "call_end_ts")
@JsonFormat(pattern="yyyy-MM-dd'T'HH:mm:ss.SSS")
private Date callEndTime;

DAO.java

ObjectMapper mapper = new ObjectMapper();
HashMap<String, Object> finalHashMap;
finalHashMap = convertMultiToString(requestMap);
mapper.enable(DeserializationFeature.ACCEPT_SINGLE_VALUE_AS_ARRAY);
CallLogEntity callLogEntity = mapper.convertValue(finalHashMap, CallEntity.class);

Change your @JsonFormat line to this.

@JsonFormat(pattern="yyyy-MM-dd'T'HH:mm:ss")

The format pattern you have right now expects the sting to have millisecond values - but your example string doesn't have them.
