最近工作中遇到个功能需要整合ehcache，由于spring版本用的是最新的4.2.4，而在ehcache官网找到的集成配置文档是spring3.1的，因此配了几次都不成功，在历经一番波折后终于成功集成了spring4.2.4+ehcache2.10.1，这里贴一下相关的配置，以作记录。
maven->pom.xml
spring:略
ehcache:只需要引入下面这一个jar就可以了，spring4里对缓存的注解进行了加强，因此不需要引入ehcache-spring-annotations.jar
<dependency>
<groupId>net.sf.ehcache</groupId>
<artifactId>ehcache</artifactId>
<version>2.10.1</version>
</dependency>
ehcache.xml：关于里面的参数说明，请参考http://www.cnblogs.com/sunxucool/p/3159076.html
<?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="java.io.tmpdir" /> <defaultCache
maxElementsInMemory="10000"
maxElementsOnDisk="0"
eternal="true"
overflowToDisk="true"
diskPersistent="false"
timeToIdleSeconds="0"
timeToLiveSeconds="0"
diskSpoolBufferSizeMB="50"
diskExpiryThreadIntervalSeconds="120"
memoryStoreEvictionPolicy="LFU" /> <cache name="myCache"
maxElementsInMemory="1000"
maxElementsOnDisk="0"
eternal="false"
overflowToDisk="false"
diskPersistent="false"
timeToIdleSeconds="120"
timeToLiveSeconds="300"
diskSpoolBufferSizeMB="50"
diskExpiryThreadIntervalSeconds="120"
memoryStoreEvictionPolicy="LFU" /> </ehcache>
spring配置:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

</bean> </beans>
java代码使用:注意这个@Cacheable注解，和以前用过spring-ehcache的@Cacheable用法稍有区别
@Cacheable(value = "myCache", key="#condition")
public <T> T findXX(String condition) {
// 业务代码，ehcache会将该方法的返回结果缓存起来
}
