關於spring集成ehcache作分佈式的問題記錄

記錄問題1：分佈式採用了rmi配置，可是配置後一直沒有做用，控制檯報如下警告：

[WARN] 10:19:59 [main CacheManager:292] -
The source of the configuration was classpath.
The diskStore path for this CacheManager will be set to C:\apache-tomcat-5.5.16\temp\ehcache_auto_created_1168453199935.

To avoid this warning consider using the CacheManager factory methods to create a singleton CacheManager or specifying a
separate ehcache configuration (ehcache.xml) for each CacheManager instance.>

[WARN] 10:19:59 [main CacheManager:319] -
The resource is RMI listener port: 40001.
Attempting automatic resolution. The source of the configuration was classpath.
To avoid this warning consider using the CacheManager factory methods to create a singleton CacheManager or specifying a
separate ehcache configuration (ehcache.xml) for each CacheManager instance.>

Station [WARN] 10:19:59 [main RMICacheManagerPeerListener:145] -

 

解決辦法：在spring中ehcache配置中須要增長屬性：property name="shared" value="true"

完成配置以下：

 

<bean id="cacheManager" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean">
		<property name="configLocation" value="classpath:ehcache.xml" />
		<property name="shared" value="true"/>
	</bean>

記錄問題二：ehcache.xml配置信息以下所示：

<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="ehcache.xsd">
    <diskStore path="java.io.tmpdir"/>

            eternal="false"
            timeToIdleSeconds="120"
            timeToLiveSeconds="120"
            overflowToDisk="true"
            diskPersistent="false"
            diskExpiryThreadIntervalSeconds="120"

           timeToLiveSeconds="600"
           memoryStoreEvictionPolicy="LFU"
           >

            >
