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>
<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>

4,aop相应的类,只要对上面的通过BeanName捕获到,执行相应的AOP处理相应的缓存放入和移出。
