Fabrika yöntemlerini incelemek için sınıf dosyası bulunamadı: java.util.concurrent.ThreadPoolExecutor.DiscardPolicy

Question

Lütfen, kısaca kalmama yardım edin. Savaş dosyamı Jboss üzerinde dağıtırken, bu aşağıdaki hatayı gösteriyor. Nedenin ne olduğunu öğrenmek için kendime takıldım.

[oscannotation.ConfigurationClassUtils]: java.util.concurrent.ThreadPoolExecutor.DiscardPolicy java.io.FileNotFoundException: fabrika yöntemleri introspecting için sınıf dosyası bulunamadı sınıf yolu kaynak [java/util/eşzamanlı/ThreadPoolExecutor/DiscardPolicy.class] o org.springframework.core.io.ClassPathResource.getInputStream de

benim yapılandırılan yay fasulye ref enjeksiyonu ile

sorun bulduk

Çözüm.

Modifiye

<bean id="taskExecutor" class="org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor"> <property name="corePoolSize" value="100" /> <property name="maxPoolSize" value="50" /> <property name="queueCapacity" value="150" /> <property name="rejectedExecutionHandler" ref="discardPolicy" /> </bean> <bean id="discardPolicy" class="java.util.concurrent.ThreadPoolExecutor.DiscardPolicy"/>
