无法从字符串反序列化类型为java.util.Date的值 [英] Cannot deserialize value of type `java.util.Date` from String

问题描述

使用Spring 1.5.8.RELEASE 杰克逊(Jackson)映射器给出以下异常.

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 [来源:UNKNOWN;行:-1，列:-1](通过参考链:com.copart.conversationapi.calldisposition.model.vo.CallLogEntity ["callEndTime"])

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

CallEntity.java

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);

推荐答案

将@JsonFormat行更改为此.

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

您现在拥有的格式模式期望字符串具有毫秒值-但您的示例字符串中没有毫秒值.

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