Spring Data Elastic Search 4.0.3 - 日期字段列表

Question

Lets say i have I have a list of birthdates

@Field(type = FieldType.Nested, includeInParent = true, format = DateFormat.date)
private List<LocalDate> birthdates = new ArrayList<>();

What is the proper way to map this using spring data without getting this error.. No converter found capable of converting from type [java.lang.Long] to type [java.time.LocalDate]

Do I really need to create a custom converter? or a wapper object? I would think this would be supported out of the box.

Thank you in advance.

Answer 1

The correct way to annotate this property should be

@Field(type = FieldType.Date, format = DateFormat.date)
private List<LocalDate> birthdates = new ArrayList<>();

This would write the mappings entry as type date and format date , and storing and searching the array would work.

The bad news is that the current version of Spring Data Elasticsearch does not handle this correctly.

The good news is, that I just implemented the fix for this, it will be contained in versions 4.0.4.RELEASE and 4.1.0.RC1; both are planned to be released tomorrow.

Edit: both versions are released now
