Ehcache缓存配置

Ehcache缓存配置

近期项目用到Ehcache，以前项目主要用到Oscache,并且缓存也是针对orm来处理，只要配置就好，不需要自定义缓存，不需管理缓存。下面描述一下，Spring+Ehcache来处理缓存。

1，首先引入jar包就不说了环境也不说了，要引入ehcache.xml文件(ehcache配置文件)。

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

      <diskStore path="java.io.tmpdir"/>

      <cacheManagerEventListenerFactory class="" properties=""/>


    <cacheManagerPeerListenerFactory
            class="net.sf.ehcache.distribution.RMICacheManagerPeerListenerFactory"/>


     <defaultCache
            maxElementsInMemory="10000"
            eternal="false"
            timeToIdleSeconds="120"
            timeToLiveSeconds="120"
            overflowToDisk="true"
            diskSpoolBufferSizeMB="30"
            maxElementsOnDisk="10000000"
            diskPersistent="false"
            diskExpiryThreadIntervalSeconds="120"
            memoryStoreEvictionPolicy="LRU"
            />

    <Cache  name="InstantCache"
            maxElementsInMemory="100000"
            eternal="false"
            timeToIdleSeconds="120"
            timeToLiveSeconds="300"
            overflowToDisk="true"
            diskSpoolBufferSizeMB="30"
            maxElementsOnDisk="10000000"
            diskPersistent="false"
            diskExpiryThreadIntervalSeconds="120"
            memoryStoreEvictionPolicy="LRU"
            />
    <Cache  name="fixCache"
            maxElementsInMemory="100000"
            eternal="true"
            timeToIdleSeconds="120"
            timeToLiveSeconds="120"
            overflowToDisk="false"
            diskSpoolBufferSizeMB="30"
            maxElementsOnDisk="10000000"
            diskPersistent="false"
            diskExpiryThreadIntervalSeconds="120"
            memoryStoreEvictionPolicy="LRU"
            />
    <Cache  name="methodCache"
            maxElementsInMemory="100000"
            eternal="false"
            timeToIdleSeconds="300000"
            timeToLiveSeconds="600000"
            overflowToDisk="true"
            diskSpoolBufferSizeMB="30"
            maxElementsOnDisk="10000000"
            diskPersistent="false"
            diskExpiryThreadIntervalSeconds="120"
            memoryStoreEvictionPolicy="LRU"
            />



</ehcache>
