如何设置所有Ignite缓存的到期时间? [英] How to set expiry time for all Ignite caches?

问题描述

我正在通过特定配置开始点火.在该配置中，我指定了过期策略.但是过期是行不通的.当我在该属性中指定缓存名称时，它可以正常工作.

I am starting ignite by a specific configuration. In that configuration, I specified expiration policy. But expiration is not working. When I specified a cache name in that property, it is working fine.

我添加了如下配置

<property name="expiryPolicyFactory">
        <bean class="javax.cache.expiry.CreatedExpiryPolicy" factory-method="factoryOf">
            <constructor-arg>
                <bean class="javax.cache.expiry.Duration">
                    <constructor-arg value="MINUTES"/>
                    <constructor-arg value="5"/>
                </bean>
            </constructor-arg>
       </bean>
   </property>

但这不适用于所有缓存，

But this is not working for all caches,

当我尝试如下配置时，

<bean class="org.apache.ignite.configuration.CacheConfiguration">
                     <property name="expiryPolicyFactory">
                      <bean class="javax.cache.expiry.CreatedExpiryPolicy" factory-method="factoryOf">
                        <constructor-arg>
                          <bean class="javax.cache.expiry.Duration">
                            <constructor-arg value="SECONDS"/>
                            <constructor-arg value="5"/>
                          </bean>
                        </constructor-arg>
                      </bean>
                    </property>
                    <property name="name" value="test"/>
                    <property name="atomicityMode" value="ATOMIC"/>
                    <property name="backups" value="1"/>
                </bean>

此处缓存测试"正确到期.

Here the cache "test" is expiring correctly.

推荐答案

您可以声明一个包含< expiryPolicyFactory> 的抽象 CacheConfiguration bean，并继承(使用 parent ="beanName" )来自该bean的所有缓存cfg.在春季通常是这样的:

You can declare an abstract CacheConfiguration bean containing <expiryPolicyFactory>, and inherit (using parent="beanName") all of cache cfg's from that bean. That's how it usually done in Spring:

<bean id="expireCache" class="org.apache.ignite.configuration.CacheConfiguration" abstract="true">
    <property name="expiryPolicyFactory">
        <bean class="javax.cache.expiry.CreatedExpiryPolicy" factory-method="factoryOf">
            <constructor-arg>
                <bean class="javax.cache.expiry.Duration">
                    <constructor-arg value="MINUTES"/>
                    <constructor-arg value="5"/>
                </bean>
            </constructor-arg>
       </bean>
    </property>
</bean>

    <property name="cacheConfiguration">
        <list>
            <bean parent="expireCache">
                <property name="name" value="test"/>
                <property name="atomicityMode" value="ATOMIC"/>
                <property name="backups" value="1"/>
            </bean>
...

抽象Bean应该与IgniteConfiguration Bean一起放在顶层.

Abstract bean should be put on the top level alongside with IgniteConfiguration bean.
