Page's content type isn't correct

[FULaBUla]

@Query("select .....")
Page<LinkedHashMap<String, Object> query(Pageable pageable);

I wish spring-data-jpa return Page<LinkedHashMap<String, Object>> but you return Page<Object[]>. The content type isn't LinkedHashMap<String, Object>, it is Object[].

According to the method I defined, the return value type I should get from Page.getContent() is LinkedHashMap<String, Object>. But actually, I get Object[] from Page.getContent().

We do not support Map as query method return type, see https://docs.spring.io/spring-data/data-jpa/reference/repositories/query-return-types-reference.html.

@mp911de The documentation doesn't specify what type of T is available in Page<T>. And when I use Page<List<Object>>, The type i get from Page.getContent() is also Object[] instead of List

[mp911de]

It does:

T A unique entity.

A Map is not an entity.

I know, but when I use Page<List<Object>>, The type i get from Page.getContent() is also Object[] instead of List
