如何通过Spring Data JPA（MySQL数据透视表）将Sum SQL分组使用？

Question

如何在Spring Data JPA中使用Sum SQL的分组（如mysql中的数据透视表）？

@Query("select new org.raznet.sgs.persistence.modelDto.etudiantNoteDto(
n.etudiant as etudiant,
sum(CASE WHEN n.exam.libelle like :a THEN  n.note ELSE 0 END) as one,
sum(CASE WHEN n.exam.libelle like :b THEN  n.note ELSE 0 END) as two,
sum(CASE WHEN n.exam.libelle like :c THEN  n.note ELSE 0 END) as thr) from Note n where n.matiere = :x group by n.etudiant")
public List<etudiantNoteDto> get(@Param("x")Matiere e,@Param("a")String a,@Param("b")String b,@Param("c")String c);

是否可以运行查询以获取如下输出：

Etudiant    exam 1   exam 2   exam 3
------------------------------------
Etudiant1   10       14       2
Etudiant2   13       14       3
