带spring的cutom ehcache收回策略

如果我们想要自定义除LRU LFU FIFO之外的逐出策略，建议使用的方法是实现接口策略，然后设置MemoryStoreReceivingPolicy，如：

manager = new CacheManager(EHCACHE_CONFIG_LOCATION);
cache = manager.getCache(CACHE_NAME);
cache.setMemoryStoreEvictionPolicy(new MyPolicy());

但是如果我使用spring，请使用@cacheable和xml文件，如

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


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

我怎样才能以春天的方式注入我自己的政策

谢谢大家

您最好实现自己的类，在Spring初始化时在缓存上设置逐出策略

例如：

public class MyEvictionPolicySetter implements InitializingBean {

    public static final String CACHE_NAME = "my_cache";

    private CacheManager manager;
    private Policy evictionPolicy;

    @Override
    public void afterPropertiesSet() {
        Cache cache = manager.getCache(CACHE_NAME);
        cache.setMemoryStoreEvictionPolicy(evictionPolicy);
    }

    public void setCacheManager(CacheManager manager) {
        this.manager = manager;
    }

    public void setEvictionPolicy(Policy evictionPolicy) {
        this.evictionPolicy = evictionPolicy;
    }
}

然后在Spring配置中：

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

<!-- Specify your eviction policy as a Spring bean -->
<bean id="evictionPolicy" class="MyPolicy"/>

<!-- This will set the eviction policy when Spring starts up -->
<bean id="evictionPolicySetter" class="EvictionPolicySetter">
    <property name="cacheManager" ref="cacheManagerFactory"/>
    <property name="evictionPolicy" ref="evictionPolicy"/>
</bean>
