Question

这是bean部分。

<bean class="org.apache.ignite.configuration.CacheConfiguration">
     <property name="name" value="cfgCache"/>
     <property name="cacheMode" value="REPLICATED"/>
     <property name="static.DFLT_CACHE_SIZE" value="1000000"/>
     <!--property name="atomicityMode" value="ATOMIC"/-->
</bean>

如何设置DFLT_CACHE_SIZE的值？或任何静态场？

文档：

static int  DFLT_CACHE_SIZE
Default cache size to use with eviction policy.
DFLT_CACHE_SIZE = 256MB

Apache点燃基于spring框架。

Answer 1

您可以通过在Ignite的逐出策略中设置max field来覆盖它，而不是设置此默认值。例如：

<bean class="org.apache.ignite.configuration.CacheConfiguration">
            <property name="name" value="cfgCache"/>
            <property name="cacheMode" value="REPLICATED"/>
            <property name="evictionPolicy">
                <bean class="org.apache.ignite.cache.eviction.sorted.SortedEvictionPolicy">
                    <property name="maxSize" value="100"/>
                </bean>
            </property>
</bean>

Answer 2

public static final int DFLT_CACHE_SIZE = 100000;

这不仅仅是静态领域。这是一个最终字段，无法使用spring配置更改它。

如何在xml中点燃运行配置中设置静态字段的值
