Question

在我的项目中，我一直在 XYZ war 中使用 ABC jar ，两者都使用Spring 3.1实现 ehCache，xml驱动配置（我们有ehCache.xml，然后是spring-context.xml，我们在两个项目中通过Spring AOP拦截缓存。我们收到了以下错误：

java.lang.IllegalArgumentException: Cannot find cache named [xxxxxx] for CacheableOperation[] caches=[Cxxxxxxxx] | condition='' | key='#xxxxxxxxxxxxx'

<强>解决方案：

这就是我们解决这个问题的方法：

我们将所有缓存配置从ABCehCache.xml（从ABC jar）复制到XYZehCache.xml（来自XYZ战争）。
我们删除了ABCehCache.xml（来自ABC jar），但ehCache.xml内的所有配置（如ABC-spring.xml和Spring AOP的bean实例化）都将保持不变。
在XYZ-spring.xml中，我们导入了ABC-spring.xml并定义了复合缓存管理器。

支持的配置文件：

<强> ABC-spring.xml：

    <aop:aspectj-autoproxy proxy-target-class="true" />

    <bean id="CacheManager1" class="org.springframework.cache.ehcache.EhCacheCacheManager">
        <property name="cacheManager" ref="ehcache"></property>
    </bean>

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

<强> XYZ-spring.xml：

<import resource="classpath*:ABC-spring.xml" />
<aop:aspectj-autoproxy proxy-target-class="true" />

    <bean id="cacheManager" class="org.springframework.cache.support.CompositeCacheManager">
    <property name="cacheManagers">
        <array>
            <ref bean="CacheManager1" />
            <ref bean="CacheManager2" />
        </array>
    </property>
    <property name="fallbackToNoOpCache" value="true" />
</bean>

    <bean id="CacheManager2" class="org.springframework.cache.ehcache.EhCacheCacheManager"
        p:cache-manager-ref="ehcache" />
    <bean id="ehcache"
        class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean"
        p:config-location="classpath:XYZEhcache.xml" />

希望这会有所帮助!!

Spring 3.1 ehCache in jar and war其中jar将在war中使用：XML配置
