JPARepository中的自定义查询

Question

我想根据用户选择在String变量中创建自定义查询，然后我想插入@Query并执行它 例如

class RequestResource
.
.
String query = "select r from Request r";
requestRepository.test(query);
.
.


class RequestRepository
.
.
@Query("?1")
List<Request> test(String query);
.
.

我想我用这个来解决它

    String finalQuery = "select r from Request r " + leftJoins + " where " + queryParams;
    log.error("QUERY " + finalQuery);
    TypedQuery<Request> query1 = em.createQuery(finalQuery, Request.class);
