Ignite缓存管理初体验

Ignite缓存管理初体验:ignite服务端配置,大家可以用参考官方进行配置(或者使用默认配置也可以)。
本文中的ignite使用版本是1.7,与spring结合使用。
maven依赖配置
ignite 客户端配置
<property name="clientMode" value="true"><!--声明为客户端--> <!-- Explicitly configure TCP discovery SPI to provide list of initial nodes. -->
<property name="discoverySpi">
<bean class="org.apache.ignite.spi.discovery.tcp.TcpDiscoverySpi">
<property name="ipFinder">
<!--
Ignite provides several options for automatic discovery that can be used
instead os static IP based discovery. For information on all options refer
to our documentation: https://apacheignite.readme.io/docs/cluster-config
-->
<!-- Uncomment static IP finder to enable static-based discovery of initial nodes. -->
<!--<bean class="org.apache.ignite.spi.discovery.tcp.ipfinder.vm.TcpDiscoveryVmIpFinder">-->
<bean class="org.apache.ignite.spi.discovery.tcp.ipfinder.multicast.TcpDiscoveryMulticastIpFinder">
<property name="addresses">
<list>
<!-- In distributed environment, replace with actual host IP address. -->
<value>${ignite.serverIp}</value><!--服务端IP地址-->
</list>
</property>
</bean>
</property>
</bean>
</property>
<property name="communicationSpi">
<bean class="org.apache.ignite.spi.communication.tcp.TcpCommunicationSpi">
<property name="localPort" value="${ignite.communication.localport}"><!--对接服务端端口-->
<property name="localAddress" value="192.168.1.93"><!--ignite客户端链接地址(适用多网卡情况)-->
</property></property></bean>
