Object of class [org.springframework.data.jpa.repository.query.PartTreeJpaQuery] must be an instance of class org.springframework.data.jpa.repository.query.StoredProcedureJpaQuery; nested exception is java.lang.IllegalArgumentException: Object of class [org.springframework.data.jpa.repository.query.PartTreeJpaQuery] must be an instance of class org.springframework.data.jpa.repository.query.StoredProcedureJpaQuery

我以前从未将Spring Data JPA与存储过程一起使用过，但我非常感谢这里的任何反馈/输入

Answer 1

我从来没有找到一个解决办法，也没有找到一个不同的方法

@Repository 
public interface MyObjectRepository extends CrudRepository<MyObject, String>  {
    @Query(value = "EXECUTE [dbo].[myProc] :fieldName, :pages", nativeQuery = true)
    Set<MyObject> findAllByFieldName(@Param("fieldName") String fieldName, @Param("pages") int pages);
}

这是一个与我建议的答案相同的问题
