春季3.1的Ehcache在罐子和战争，其中罐子将战争中使用：

Question

在项目中，我一直在使用ABC XYZ战争内罐子 XML配置，既实现的Ehcache与Spring 3.1，XML驱动的配置 （我们有ehCache.xml，然后在两个项目中通过Spring AOP拦截缓存的spring-context.xml）。而我们得到以下错误：

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

Answer 1

解决方案：

这就是我们解决了这个问题：

1. 我们复制从ABCehCache.xml所有的缓存配置（从ABC JAR）到XYZehCache.xml（来自XYZ战争）。
2. 我们删除了ABCehCache.xml（来自ABC jar），但ABC-spring.xml中的所有配置（如ehCache.xml和Spring AOP的bean实例化）将保持不变。
3. 在XYZ-spring.xml中，我们导入ABC-spring.xml并定义了复合缓存管理器。

支持的配置文件：

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" /> 

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" /> 

希望这将有助于！
