在GoogleAppEngine

Question

我遷移我的春天項目的其中一個包含ehcaching到GoogleAppEngine， 與Spring實現了Ehcache但我得到的異常以下：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.cache.config.internalCacheAdvisor': Cannot resolve reference to bean 'org.springframework.cache.annotation.AnnotationCacheOperationSource#0' while setting bean property 'cacheOperationSource'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.cache.annotation.AnnotationCacheOperationSource#0': Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.cache.config.internalJCacheAdvisor': Cannot resolve reference to bean 'org.springframework.cache.jcache.interceptor.DefaultJCacheOperationSource#0' while setting bean property 'cacheOperationSource'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.cache.jcache.interceptor.DefaultJCacheOperationSource#0': Cannot resolve reference to bean 'cacheManager' while setting bean property 'cacheManager'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'cacheManager' defined in class path resource [root-context.xml]: Cannot resolve reference to bean 'ehcache' while setting bean property 'cacheManager'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'ehcache' defined in class path resource [root-context.xml]: Invocation of init method failed; nested exception is net.sf.ehcache.CacheException: java.security.AccessControlException: access denied ("java.lang.RuntimePermission" "modifyThreadGroup")

這裏是我的配置文件：

網.XML

<servlet> 
    <servlet-name>appServlet</servlet-name> 
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 
    <init-param> 
     <param-name>contextConfigLocation</param-name> 
     <param-value>/WEB-INF/spring/appServlet/servlet-context.xml</param-value> 
    </init-param> 
    <load-on-startup>1</load-on-startup> 
</servlet> 
<servlet-mapping> 
    <servlet-name>appServlet</servlet-name> 
    <url-pattern>/</url-pattern> 
</servlet-mapping> 

ehcache.xml中

<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xsi:noNamespaceSchemaLocation="http://ehcache.org/ehcache.xsd"> 
<cacheManagerEventListenerFactory class="" properties="" /> 
<defaultCache maxElementsInMemory="10000" 
    eternal="false" 
    overflowToDisk="false" 
    diskPersistent="false" 
    timeToIdleSeconds="120" 
    timeToLiveSeconds="120" 
    memoryStoreEvictionPolicy="LRU"> 
</defaultCache> 
<!--Example sample cache --> 
<cache name="sampleCache1" 
    overflowToDisk="false" 
    diskPersistent="false" 
    maxElementsInMemory="100" 
    eternal="false" 
    timeToLiveSeconds="86400" 
    memoryStoreEvictionPolicy="LFU" /> </ehcache> 

的servlet-context.xml的

<context:component-scan base-package="com.abc.xyz.*" /> 
<annotation-driven /> 
<resources mapping="/resources/**" location="/resources/" /> 
<beans:import resource="classpath:root-context.xml" /> 

根的context.xml

<cache:annotation-driven cache-manager="cacheManager" /> 
<beans:import resource="classpath:ehcache.xml" /> 
<beans:bean id="cacheManager" 
    class="org.springframework.cache.ehcache.EhCacheCacheManager"> 
    <beans:property name="cacheManager" ref="ehcache" /> 
</beans:bean> 
<beans:bean id="ehcache" 
    class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean"> 
    <beans:property name="configLocation" value="classpath:ehcache.xml" /> 
</beans:bean> 

我使用以下版本：

• GAE 46年9月1日
• ehcahe 2.9。 1
• spring 4.3.2.RELEASE

感謝，

正如latest documentation指出，在使用的Ehcache時限制在谷歌應用程序引擎。 GAE是一些受限制的環境，其中一些API不可用。

您需要從配置中刪除<cacheManagerEventListenerFactory class="" properties="" />位。
