Hibernate 配置二级缓存

前几天配置了二级缓存，特此记录一下。

第一步：

添加POM.XML dependency

<dependency>
			<groupId>org.hibernate</groupId>
			<artifactId>hibernate-ehcache</artifactId>
			<version>3.6.2.Final</version>
		</dependency>

第二步：

Hibernate.cfg.xml

<property name="hibernate.cache.use_second_level_cache">true</property>
		<property name="hibernate.cache.provider_class">
			org.hibernate.cache.EhCacheProvider
		</property>

第三步：
在需要缓存的class.hbm.xml 添加声明

 <class name="test" table="CMN_test" >
    
    	<cache usage="read-write"/>
    	
        <id name="id" type="string">
            <column name="ID" length="50" />
            <generator class="assigned" />
        </id>

第三步：
编写ehcache.xml

<?xml version="1.0" encoding="UTF-8"?>

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

    <diskStore path="c:/ehcache" />

    <defaultCache eternal="false" maxElementsInMemory="1000"
        overflowToDisk="false" diskPersistent="false" timeToIdleSeconds="0"
        timeToLiveSeconds="600" memoryStoreEvictionPolicy="LRU" statistics="true" />

    <cache name="com.pulse.ipmanager.egress.CmnAnumberbypass" eternal="false" 
        maxElementsInMemory="100" overflowToDisk="false" diskPersistent="false"
        timeToIdleSeconds="50" timeToLiveSeconds="300"
        memoryStoreEvictionPolicy="LRU" statistics="true" />

 </ehcache>

最后检查一下：

getting CmnAnumberbypass instance with id: b5bd40a7-1330-4b0e-93a1-395ce84aaedd
2012-05-09 15:26:16,949 DEBUG (net.sf.ehcache.store.MemoryStore:135) - Cache: CmnAnumberbypassMemoryStore hit for CmnAnumberbypass#b5bd40a7-1330-4b0e-93a1-395ce84aaedd
2012-05-09 15:26:16,951 DEBUG (CmnAnumberbypassHome:123) - get successful, instance found
