如何在XML配置中使用GridGain缓存模板配置cacheA与cacheB？

核心配置逻辑 #

GridGain的缓存模板通过<cache-template>定义通用配置，具体缓存通过template属性引用模板，同时可按需覆盖或补充特有属性，避免重复配置。

完整示例代码 #

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:ignite="http://www.gridgain.com/schema/ignite"
       xsi:schemaLocation="
        http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.gridgain.com/schema/ignite
        http://www.gridgain.com/schema/ignite/ignite.xsd">

    <!-- 定义通用缓存模板：抽离重复配置项 -->
    <ignite:cache-template id="common-cache-template">
        <ignite:cache-mode>PARTITIONED</ignite:cache-mode>
        <ignite:backups>1</ignite:backups>
        <ignite:expiry-policy>
            <bean class="org.apache.ignite.cache.CacheExpiryPolicy">
                <property name="createTimeout" value="3600000"/> <!-- 创建后1小时过期 -->
            </bean>
        </ignite:expiry-policy>
        <ignite:storage-settings>
            <ignite:off-heap-max-memory value="10GB"/>
        </ignite:storage-settings>
    </ignite:cache-template>

    <!-- 缓存A：引用模板，仅配置专属属性 -->
    <ignite:cache name="cacheA" template="common-cache-template">
        <ignite:key-value-config>
            <ignite:key-type>java.lang.String</ignite:key-type>
            <ignite:value-type>com.example.User</ignite:value-type>
        </ignite:key-value-config>
    </ignite:cache>

    <!-- 缓存B：引用模板，覆盖模板属性+配置专属属性 -->
    <ignite:cache name="cacheB" template="common-cache-template">
        <ignite:backups>2</ignite:backups> <!-- 覆盖模板的备份数配置 -->
        <ignite:key-value-config>
            <ignite:key-type>java.lang.Long</ignite:key-type>
            <ignite:value-type>com.example.Order</ignite:value-type>
        </ignite:key-value-config>
    </ignite:cache>

</beans>

关键验证点 #

• 若你的配置中，cacheA和cacheB通过template属性绑定了对应的缓存模板ID，且仅补充/覆盖特有属性，这种写法是正确的。
• 模板未定义的属性可在具体缓存中追加；模板已定义的属性，具体缓存中的配置会自动覆盖模板值（如示例中cacheB的备份数）。
