我正在测试Spring缓存,这是我的上下文文件
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:cache="http://www.springframework.org/schema/cache"
xsi:schemaLocation=
"http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/cache http://www.springframework.org/schema/cache/spring-cache.xsd">
<cache:annotation-driven cache-manager="simpleCacheManager"/>
<bean id="simpleCacheManager" class="org.springframework.cache.support.SimpleCacheManager">
<property name="caches">
<set>
<bean class="org.springframework.cache.concurrent.ConcurrentCacheFactoryBean">
<property name="name" value="alfresco"/>
</bean>
<bean class="org.springframework.cache.concurrent.ConcurrentCacheFactoryBean">
<property name="name" value="alfresco_article"/>
</bean>
<bean class="org.springframework.cache.concurrent.ConcurrentCacheFactoryBean">
<property name="name" value="alfresco_action"/>
</bean>
</set>
</property>
</bean>
我添加了所有必需的库但是,我无法验证库,因为Eclipse仍然告诉我AOPAlliance.jar和org.springframework.context-3.1.1.RELEASE.jar缺失。
错误是:
此行发现了多个注释:找不到类org.springframework.cache.concurrent.ConcurrentCacheFactoryBean。
已修改为org.springframework.cache.concurrent.ConcurrentMapCacheFactoryBean
但是,调用url会发生这种情况:
org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.springframework.beans.factory.BeanDefinitionStoreException: Unexpected exception parsing XML document from class path resource [configuration-context.xml]; nested exception is java.lang.NoClassDefFoundError: org/springframework/aop/config/AopNamespaceUtils
org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:894)
org.springframework.web.servlet.FrameworkServlet.doGet(FrameworkServlet.java:778)
javax.servlet.http.HttpServlet.service(HttpServlet.java:621)
javax.servlet.http.HttpServlet.service(HttpServlet.java:722)
root cause
org.springframework.beans.factory.BeanDefinitionStoreException: Unexpected exception parsing XML document from class path resource [configuration-context.xml]; nested exception is java.lang.NoClassDefFoundError: org/springframework/aop/config/AopNamespaceUtils
org.springframework.beans.factory.xml.XmlBeanDefinitionReader.doLoadBeanDefinitions(XmlBeanDefinitionReader.java:412)
aop-alliance.jar和org.springframework.aop-3.1.1.RELEASE.jar都在类路径中。
有任何线索吗?
谢谢,

答案 0 :(得分:20)
仔细检查org.springframework.context-3.1.1.RELEASE.jar确实在类路径上。 Eclipse验证和错误都指向了这个问题。
更新:我已经检查过了,你是对的。似乎自3.1.0.M1以来ConcurrentCacheFactoryBean
被删除,并且可能在同一个包中被ConcurrentMapCacheFactoryBean
替换。我还没有在发行说明中找到任何证据。但是,如果将缓存的bean类名称更改为ConcurrentMapCacheFactoryBean
,它似乎可以正常工作。
<bean class="org.springframework.cache.concurrent.ConcurrentMapCacheFactoryBean">
<property name="name" value="alfresco"/>
</bean>
UPDATE2:是的,确实ConcurrentCacheFactoryBean
已经renamed到ConcurrentMapCacheFactoryBean
。他们只是没有到处更新教程。
