넣어 최대 절전 모드에서 ehCache 널 포인터 예외

Question

여기 내 설정입니다.

<?xml version="1.0" encoding="UTF-8"?> 

<ehcache>  
<defaultCache 
    maxElementsInMemory="500000" 
    eternal="false" 
    timeToIdleSeconds="120" 
    timeToLiveSeconds="120" 
    overflowToDisk="true" 
/> 
<cache 
    name="com.icon.sa.common.dm.PromoItem" 
    maxElementsInMemory="500000" 
    eternal="false" 
    timeToIdleSeconds="300" 
    timeToLiveSeconds="600" 
    overflowToDisk="true" 
/> 
<cache 
    name="org.hibernate.cache.StandardQueryCache" 
    maxElementsInMemory="500000" 
    eternal="false" 
    timeToLiveSeconds="120" 
    overflowToDisk="true"/> 
<cache 
    name="org.hibernate.cache.UpdateTimestampsCache" 
    maxElementsInMemory="500000" 
    eternal="true" 
    overflowToDisk="true"/> 

<cache name="query.PromosBySearchRequestFindAction" 
    maxElementsInMemory="500000" 
    eternal="false" 
    timeToLiveSeconds="86400" 
    overflowToDisk="true"/> 

</ehcache>

Answer 1

이있다 EHCache는 그 자체와는 거의.

결과 유형 중 하나 (또는 ​​전체)가 null이므로 오류가 발생합니다.

스택 추적에서 판단하면 엔티티에 대한 사용자 정의 로더를 구성했습니다. 결과가 올바르게 선언되지 않았거나 (결과 클래스/반환 별칭) 또는 캐싱과 함께 지원되지 않는 유형 ("select * ..."으로 선언 된)을 자동으로 검색해야 할 가능성이 있습니다.
