ある間隔時間に基づいてメソッドを呼び出そうとしています。ここに applicationContext.xml 内のいくつかの Bean があります
<bean id="MngtTarget"
class="com.management.engine.Implementation"
abstract="false" lazy-init="true" autowire="default" dependency-check="default">
<bean id="jobDetail" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
<property name="targetObject" ref="MngtTarget" />
<property name="targetMethod" value="findItemByPIdEndDate"/>
</bean>
<bean id="simpleTrigger" class="org.springframework.scheduling.quartz.SimpleTriggerBean">
<property name="jobDetail" ref="jobDetail" />
<!-- 10 seconds -->
<property name="startDelay" value="10000" />
<!-- repeat every 50 seconds -->
<property name="repeatInterval" value="20000" />
</bean>
<bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
<property name="triggers">
<list>
<ref bean="simpleTrigger" />
</list>
</property>
</bean>
これが私が呼び出そうとしているメソッドです:
public List<Long> I need findItemByPIdEndDate() throws Exception {
List<Long> list = null;
try{
Session session = sessionFactory.getCurrentSession();
Query query = session.getNamedQuery("endDateChecker");
list = query.list();
for(int i=0; i<list.size(); i++)
{
System.out.println(list.get(i));
}
System.out.println("Total " + list.size());
}catch (HibernateException e){
throw new DataAccessException(e.getMessage());
}
return list;
}
これが私が得る例外メッセージです:
Invocation of method 'findItemByPIdEndDate' on target class [class com.management.engine.Implementation] failed; nested exception is No Hibernate Session bound to thread, and configuration does not allow creation of non-transactional one here
私はこれまでグーグルで多くの時間を費やしてきましたが、次のようにメソッドを変更しようとしました:
public List<Long> I need findItemByPIdEndDate() throws Exception {
List<Long> list = null;
try{
Session session = sessionFactory.openSession();
Query query = session.getNamedQuery("endDateChecker");
list = query.list();
for(int i=0; i<list.size(); i++)
{
System.out.println(list.get(i));
}
System.out.println("Total " + list.size());
session.close();
}catch (HibernateException e){
throw new DataAccessException(e.getMessage());
}
return list;
}
そして、別のエラー メッセージが表示Invocation of method 'findItemByPIdEndDate' on target class [class com.management.engine.Implementation] failed; nested exception is could not execute query]されます。ありがとうございました
また、私のqueries.hbm.xml
<hibernate-mapping>
<sql-query name="endDateChecker">
<return-scalar column="PId" type="java.lang.Long"/>
<![CDATA[select
item_pid as PId
from
item
where
end_date < trunc(sysdate)]]>
</sql-query>
</hibernate-mapping>
