글쎄 내 클래스 목록에 객체 목록을 캐스팅하려고하는데 위 오류가 발생합니다 (아래 전체 오류 정보). 나는 주위를 둘러 보았고 제안을 시도했지만 잘못된 것을 볼 수는 없다. POJO 클래스에 중단 점을 넣으려고했지만 작동하지 않았습니다. 웹 애플리케이션에서는 중단 점이 작동하지 않는다고 생각합니다.java.lang.IllegalArgumentException : setResultTransformer (최대 절전 모드)를 사용하는 인수 유형 불일치
내가 검색하는 필드 (instance_id)는 Oracle 11GR2 DB에서 번호로 선언됩니다.
도와 주시겠습니까?
내 기본 쿼리 (내 HBM 파일에 정의와 내가 함께하고 수익 스칼라없이 시도했다) 내 자바 코드
List<EventSession> eventSessionList1 = sessionFactory.getCurrentSession()
.getNamedQuery("getEventSessionsForFab1")
.setParameter("eventName", "%" + (lovList.size() > 0 ? lovList.get(0).getCode().toLowerCase() : "general") + "%")
.setResultTransformer(Transformers.aliasToBean(EventSession.class))
.list();
내 자바
<sql-query name="getEventSessionsForFab1">
<return-scalar column="instanceId" type="long" />
<![CDATA[select eventInstance.instance_id as "instanceId" from events event, event_instances eventInstance where event.event_id = eventInstance.event_id and eventInstance.start_date_time > sysdate and (eventInstance.register_cutoff_date >= sysdate or eventInstance.register_cutoff_date is null) and (lower(event.event_name) like :eventName or event.event_id = 1)]]>
</sql-query>
클래스 (여기에는 더 많은 필드가 있었지만 테스트를 위해 1 개만 남았습니다)
멀리 가야 오류를 정수로 긴에서 리턴 스칼라을 변경하면package com.myapps.issu.models.database;
public class EventSession {
private Integer instanceId;
public Integer getInstanceId() {
return instanceId;
}
public void setInstanceId(Integer instanceId) {
this.instanceId = instanceId;
}
}
전체 오류 메시지 이클립스 콘솔에 표시되는
