@JSONField时间格式不兼容了

2.0.16版本字段@JSONField(format = "yyyy-MM-dd HH:mm:ss")，提交的表单字段格式yyyy-MM-dd HH:mm还能提交，2.0.48必须格式要求yyyy-MM-dd HH:mm:ss这种一定要一样了，如果兼容yyyy-MM-dd HH:mm

Reproduce the reported @JSONField(format = "yyyy-MM-dd HH:mm:ss") behavior with versions 2.0.16 and 2.0.48, using an input value formatted as yyyy-MM-dd HH:mm. Trace the date-field deserialization path and add a regression test if the behavior is confirmed. Done means the shorter input is accepted compatibly with 2.0.16, or the supported format change is explicitly established.
