Question

我正在尝试按照spring doc使用3.1 spring cache配置和命名空间。我还从春季网站下载了最新的jar，但我还是得到了关于名称空间的这个问题

Unable to locate Spring NamespaceHandler for element 'cache:annotation-driven' of schema namespace 'http://www.springframework.org/

模式/高速缓存“

spring配置文件

cache:annotation-driven />

<bean id="cacheManager" class="org.springframework.cache.ehcache.EhCacheCacheManager" p:cache-manager-ref="ehcache"/>
<bean id="ehcache" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean" 
    p:config-location="classpath:ehcache.xml"/>

Answer 1

您需要在类路径上使用spring-context-support.jar和spring-context.jar。

spring-context有CacheNamespaceHandler类。

（请注意，spring现在为其jar使用不同的命名方案，但context和context support保留在名称中

对于Maven用户，添加以下依赖项：

    <spring-version>3.1.0.RELEASE</spring-version>
    <ehcache-version>2.4.2</ehcache-version>

    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context</artifactId>
        <version>${spring-version}</version>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context-support</artifactId>
        <version>${spring-version}</version>
    </dependency>
    <dependency>
        <groupId>net.sf.ehcache</groupId>
        <artifactId>ehcache-core</artifactId>
        <version>${ehcache-version}</version>
    </dependency>
