我在Spring Data、Hibernate、ehcache环境中使用查询缓存。ehcache 依赖项是compile 'org.hibernate:hibernate-ehcache:3.3.1.GA'

ehcache 依赖树是

+--- org.hibernate:hibernate-ehcache:3.3.1.GA
|    +--- org.hibernate:hibernate-core:3.3.1.GA -> 3.6.6.Final (*)
|    +--- net.sf.ehcache:ehcache:1.2.3
|    |    \--- commons-collections:commons-collections:2.1 -> 3.2.1
|    \--- org.slf4j:slf4j-api:1.5.2 -> 1.6.5

我有一个resources/ehcache.xml配置timeToLiveSeconds为5 分钟。

<?xml version="1.0" encoding="UTF-8"?>
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:noNamespaceSchemaLocation="http://ehcache.org/ehcache.xsd">

<diskStore path="/home/prayag/cache_"/>
<defaultCache
        eternal="false"
        maxElementsInMemory="1000"
        overflowToDisk="true"
        diskPersistent="true"
        timeToLiveSeconds="300"
        diskExpiryThreadIntervalSeconds="300"
        memoryStoreEvictionPolicy="LRU"
        />
</ehcache>

缓存有效，但 5 分钟后，缓存不会自动刷新，也不会显示新的更改。

甚至没有遵循删除缓存的代码。

import net.sf.ehcache.Cache;
import net.sf.ehcache.CacheManager;

CacheManager cacheManager = CacheManager.getInstance();
String[] names = cacheManager.getCacheNames();
for (String name : names) {
    if (name.equals("merchantServices")) {
        Cache cache = cacheManager.getCache(name);
        cache.removeAll();
    }
}

我的缓存配置（jpa-context.xml）与 cacheName MercerServices 是

<?xml version="1.0" encoding="UTF-8"?>
<beans
    xmlns:p="http://www.springframework.org/schema/p" 
    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:mvc="http://www.springframework.org/schema/mvc"
    xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd

        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd
        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd
        http://www.springframework.org/schema/cache
        http://www.springframework.org/schema/cache/spring-cache.xsd"
    default-autowire="byName">

    <tx:annotation-driven />
    <cache:annotation-driven />
    <bean id="cacheManager" class="org.springframework.cache.support.SimpleCacheManager">
      <property name="caches">
         <set>
          <bean class="org.springframework.cache.concurrent.ConcurrentMapCacheFactoryBean" p:name="merchantServices"/>
        </set>
      </property>
    </bean>
</beans>

在diskStore缓存文件如下，

prayag@prayag:~/cache_$ ls -l

-rw-rw-r-- 1 prayag prayag    0 Sep 20 13:31 org.hibernate.cache.StandardQueryCache.data

-rw-rw-r-- 1 prayag prayag    0 Sep 20 15:26 org.hibernate.cache.UpdateTimestampsCache.index

org.hibernate.cache.UpdateTimestampsCache.data有以下内容。

基本上你正面临这里讨论的 ehcache autoflush 问题。

您的问题有一个解决方案，已在此处讨论过。希望它对您有所帮助，因为我不是 ehcache pro .. ：P
