一、ehcahe的介绍

EhCache 是一个纯Java的进程内缓存框架,具有快速、精干等特点,是Hibernate中默认的CacheProvider。Ehcache是一种广泛使用的开源Java分布式缓存。主要面向通用缓存,Java EE和轻量级容器。它具有内存和磁盘存储,缓存加载器,缓存扩展,缓存异常处理程序,一个gzip缓存servlet过滤器,支持REST和SOAP api等特点。

优点: 
1. 快速 
2. 简单 
3. 多种缓存策略 
4. 缓存数据有两级:内存和磁盘,因此无需担心容量问题 
5. 缓存数据会在虚拟机重启的过程中写入磁盘 
6. 可以通过RMI、可插入API等方式进行分布式缓存 
7. 具有缓存和缓存管理器的侦听接口 
8. 支持多缓存管理器实例,以及一个实例的多个缓存区域 
9. 提供Hibernate的缓存实现

缺点: 
1. 使用磁盘Cache的时候非常占用磁盘空间:这是因为DiskCache的算法简单,该算法简单也导致Cache的效率非常高。它只是对元素直接追加存储。因此搜索元素的时候非常的快。如果使用DiskCache的,在很频繁的应用中,很快磁盘会满。 
2. 不能保证数据的安全:当突然kill掉java的时候,可能会产生冲突,EhCache的解决方法是如果文件冲突了,则重建cache。这对于Cache数据需要保存的时候可能不利。当然,Cache只是简单的加速,而不能保证数据的安全。如果想保证数据的存储安全,可以使用Bekeley DB Java Edition版本。这是个嵌入式数据库。可以确保存储安全和空间的利用率。

EhCache的分布式缓存有传统的RMI,1.5版的JGroups,1.6版的JMS。分布式缓存主要解决集群环境中不同的服务器间的数据的同步问题。

使用Spring的AOP进行整合,可以灵活的对方法的返回结果对象进行缓存。

下面将介绍Spring+EhCache详细实例。

2.2、添加ehcache配置文件ehcache-setting.xml

<?xml version="1.0" encoding="UTF-8"?>
<ehcache>
    <!-- 指定一个文件目录,当EhCache把数据写到硬盘上时,将把数据写到这个文件目录下 -->
    <diskStore path="java.io.tmpdir"/>
    <!-- 设定缓存的默认数据过期策略 -->
    <defaultCache
            maxElementsInMemory="10000"
            eternal="false"
            overflowToDisk="true"
            timeToIdleSeconds="10"
            timeToLiveSeconds="20"
            diskPersistent="false"
            diskExpiryThreadIntervalSeconds="120"/>

    <cache name="cacheTest"
           maxElementsInMemory="1000"
           eternal="false"
           overflowToDisk="true"
           timeToIdleSeconds="10"
           timeToLiveSeconds="20"/>

</ehcache>
        <!--
        cache元素的属性:
        name:缓存名称
        maxElementsInMemory:内存中最大缓存对象数
        maxElementsOnDisk:硬盘中最大缓存对象数,若是0表示无穷大
        eternal:true表示对象永不过期,此时会忽略timeToIdleSeconds和timeToLiveSeconds属性,默认为false
        overflowToDisk:true表示当内存缓存的对象数目达到了
        maxElementsInMemory界限后,会把溢出的对象写到硬盘缓存中。注意:如果缓存的对象要写入到硬盘中的话,则该对象必须实现了Serializable接口才行。
        diskSpoolBufferSizeMB:磁盘缓存区大小,默认为30MB。每个Cache都应该有自己的一个缓存区。
        diskPersistent:是否缓存虚拟机重启期数据,是否持久化磁盘缓存,当这个属性的值为true时,系统在初始化时会在磁盘中查找文件名为cache名称,后缀名为index的文件,这个文件中存放了已经持久化在磁盘中的cache的index,找到后会把cache加载到内存,要想把cache真正持久化到磁盘,写程序时注意执行net.sf.ehcache.Cache.put(Element element)后要调用flush()方法。
        diskExpiryThreadIntervalSeconds:磁盘失效线程运行时间间隔,默认为120秒
        timeToIdleSeconds: 设定允许对象处于空闲状态的最长时间,以秒为单位。当对象自从最近一次被访问后,如果处于空闲状态的时间超过了timeToIdleSeconds属性值,这个对象就会过期,EHCache将把它从缓存中清空。只有当eternal属性为false,该属性才有效。如果该属性值为0,则表示对象可以无限期地处于空闲状态
        timeToLiveSeconds:设定对象允许存在于缓存中的最长时间,以秒为单位。当对象自从被存放到缓存中后,如果处于缓存中的时间超过了 timeToLiveSeconds属性值,这个对象就会过期,EHCache将把它从缓存中清除。只有当eternal属性为false,该属性才有效。如果该属性值为0,则表示对象可以无限期地存在于缓存中。timeToLiveSeconds必须大于timeToIdleSeconds属性,才有意义
        memoryStoreEvictionPolicy:当达到maxElementsInMemory限制时,Ehcache将会根据指定的策略去清理内存。可选策略有:LRU(最近最少使用,默认策略)、FIFO(先进先出)、LFU(最少访问次数)。
        -->

这里我们配置了cacheTest策略,10秒过期。

2.3、spring配置文件application.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:cache="http://www.springframework.org/schema/cache"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xsi:schemaLocation="

           http://www.springframework.org/schema/cache
           http://www.springframework.org/schema/cache/spring-cache-3.1.xsd">
    <!-- 自动扫描注解的bean -->
    <context:component-scan base-package="com.service"/>

    <cache:annotation-driven cache-manager="cacheManager"/>

    <bean id="cacheManager" class="org.springframework.cache.ehcache.EhCacheCacheManager">
        <property name="cacheManager" ref="ehcache"></property>
    </bean>

    <bean id="ehcache" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean">
        <property name="configLocation" value="classpath:ehcache-setting.xml"></property>
    </bean>
</beans>

2.4、EhCacheTestService接口

package com.service;

public interface EhCacheTestService {
    public String getTimestamp(String param);
}

2.5、EhCacheTestService接口实现

package com.service.impl;

import com.service.EhCacheTestService;
import org.springframework.cache.annotation.Cacheable;
import org.springframework.stereotype.Service;

@Service
public class EhCacheTestServiceImpl implements EhCacheTestService {
    @Cacheable(value = "cacheTest", key = "#param")//注解中value=”cacheTest”与ehcache-setting.xml中的cache名称属性值一致
    public String getTimestamp(String param) {
        Long timestamp = System.currentTimeMillis();
        return timestamp.toString();
    }
}

2.6、单元测试类

package com.service.impl;

import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

/**
 * Created by MyWorld on 2016/6/26.
 */
@ContextConfiguration(locations = {"classpath:application.xml"})
@RunWith(SpringJUnit4ClassRunner.class)
public class SpringTestCase {
}
package com.service.impl;

import com.service.EhCacheTestService;
import org.junit.Test;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import javax.annotation.Resource;

import java.util.concurrent.TimeUnit;

import static org.junit.Assert.*;

/**
 * Created by MyWorld on 2016/6/26.
 */
public class EhCacheTestServiceImplTest extends SpringTestCase {
    private Logger LOGGER = LoggerFactory.getLogger(EhCacheTestServiceImplTest.class);
    @Resource
    private EhCacheTestService ehCacheTestService;

    @Test
    public void testGetTimestamp() throws Exception {
        LOGGER.info("First Invoke:{}", ehCacheTestService.getTimestamp("param"));
        TimeUnit.SECONDS.sleep(2);
        LOGGER.info("Invoke After 2 second:{}", ehCacheTestService.getTimestamp("param"));
        TimeUnit.SECONDS.sleep(11);
        LOGGER.info("Invoke After 11 second:{}", ehCacheTestService.getTimestamp("param"));
    }
}
