Question

我正在尝试在Alfresco中使用spring的缓存，但是当我启动tomcat时，我得到以下异常：

org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 14 in XML document from class path resource [alfresco/module/PolmanProject-alfresco-repo/context/service-context.xml] is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: 4; columnNumber: 8; cvc-elt.1.a: Cannot find the declaration of element 'beans'.

我有以下模块上下文：

?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE beans PUBLIC '-//SPRING//DTD BEAN//EN' 'http://www.springframework.org/dtd/spring-beans.dtd'> 

<beans>
...
    <cache:annotation-driven />
    <bean id="cacheManager" class="org.springframework.cache.support.SimpleCacheManager">
        <property name="caches">
            <set>
                <bean
            class="org.springframework.cache.concurrent.ConcurrentMapCacheFactoryBean"
                    name="cacheService" />
            </set>
        </property>
    </bean>
</beans>

如果我删除了bean cacheManager，那么，我没有得到异常。

我的背景有什么问题？

您应该对该行进行评论

<!-- <!DOCTYPE beans PUBLIC '-//SPRING//DTD BEAN//EN' 'http://www.springframework.org/dtd/spring-beans.dtd'> -->

并用

替换标记

    <beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
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">

这将解决您的问题。但是，它的必要性考虑了使用缓存的另一个细节。这篇文章解释了how to use the cache step by step
