以下是缓存的配置。我想要writeThrough启用。为什么我得到以下例外?什么"作家或商店没有提供"意思?
配置:
<property name="cacheConfiguration">
<bean class="org.apache.ignite.configuration.CacheConfiguration">
<property name="name" value="txnCache"/>
<property name="cacheMode" value="PARTITIONED"/>
<property name="writeSynchronizationMode" value="FULL_SYNC"/>
<property name="writeThrough" value="true"/>
<property name="backups" value="1"/>
<!--property name="cacheMode" value="REPLICATED"/-->
<!-- <property name="atomicityMode" value="ATOMIC"/>
<property name="readFromBackup" value="true"/>
<property name="copyOnRead" value="true"/>-->
</bean>
</property>
错误:
[13:24:07,176][SEVERE][main][IgniteKernal] Got exception while starting (will rollback startup routine).

要配置直写,您需要实现CacheStore接口(或使用现有的一个)并设置cacheStoreFactory以及CacheConfiguration的writeThrough属性,它将如下所示:
<bean id= "simpleDataSource" class="org.h2.jdbcx.JdbcDataSource"/>
<bean id="ignite.cfg" class="org.apache.ignite.configuration.IgniteConfiguration">
...
<property name="cacheConfiguration">
<list>
<bean class="org.apache.ignite.configuration.CacheConfiguration">
...
<property name="writeThrough" value="true"/>
<property name="cacheStoreFactory">
<bean class="org.apache.ignite.cache.store.jdbc.CacheJdbcPojoStoreFactory">
<property name="dataSourceBean" value = "simpleDataSource" />
</bean>
</property>
</bean>
</list>
</property>
</bean>
以下是有关cacheStore和writeThrough的更多信息:

&#34;未提供作家或商店&#34;意思?
这意味着您没有在配置中提供商店。
