GET 請求中的日期參數在使用 @JsonFormat 格式化時間后報錯

@ApiModelProperty("發布時間-開始") @JsonFormat(pattern = DatePattern.NORM_DATE_PATTERN,timezone = Constants.GMT8) private Date startPublishTime; org.springframework.validation.BindException: org.springframework.validation.BeanPropertyBindingResult: 1 errors Field error in object 'algoInfoQo' on field 'startPublishTime': rejected value [2021-03-29]; codes [typeMismatch.algoInfoQo.startPublishTime,typeMismatch.startPublishTime,typeMismatch.java.util.Date,typeMismatch]; arguments [org.springframework.context.support.DefaultMessageSourceResolvable: codes [algoInfoQo.startPublishTime,startPublishTime]; arguments []; default message [startPublishTime]]; default message [Failed to convert property value of type 'java.lang.String' to required type 'java.util.Date' for property 'startPublishTime'; nested exception is org.springframework.core.convert.ConversionFailedException: Failed to convert from type [java.lang.String] to type [@io.swagger.annotations.ApiModelProperty @com.alibaba.fastjson.annotation.JSONField java.util.Date] for value '2021-03-29'; nested exception is java.lang.IllegalArgumentException]at org.springframework.web.method.annotation.ModelAttributeMethodProcessor.resolveArgument(ModelAttributeMethodProcessor.java:164) ~[spring-web-5.1.8.RELEASE.jar:5.1.8.RELEASE]
