Hi Yuci, Ignite uses Spring XML for configuration creation, so standard PropertyPlaceholderConfigurer perfectly meets your needs. Just add
<bean id="placeholderConfig" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"/> to your configuration file and it will do the trick. Make sure to consult the PropertyPlaceholderConfigurer javadoc for the available system properties resolution modes. Hope this helps, AG 2016-12-05 20:33 GMT+03:00 yucigou <yuci....@gmail.com>: > Suppose I have the following configuration file for standalone Ignite > server > nodes: > > <?xml version="1.0" encoding="UTF-8"?> > > <beans xmlns="http://www.springframework.org/schema/beans"; > xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; > xsi:schemaLocation=" > http://www.springframework.org/schema/beans > http://www.springframework.org/schema/beans/spring-beans.xsd";> > > <bean id="ignite.cfg" > class="org.apache.ignite.configuration.IgniteConfiguration"> > > <property name="peerClassLoadingEnabled" value="true"/> > > <property name="cacheConfiguration"> > <list> > <bean class="org.apache.ignite. > configuration.CacheConfiguration"> > <property name="name" > value="my-cache" /> > > <property name="cacheMode" > value="PARTITIONED"/> > <property name="backups" > value="1"/> > </bean> > </list> > </property> > > <property name="discoverySpi"> > <bean class="org.apache.ignite.spi. > discovery.tcp.TcpDiscoverySpi"> > <property name="ipFinder"> > <bean > class="org.apache.ignite.spi.discovery.tcp.ipfinder.vm. > TcpDiscoveryVmIpFinder"> > <property name="addresses"> > <bean > class="org.springframework.util.StringUtils" > factory-method="commaDelimitedListToSet"> > > <constructor-arg type="java.lang.String" > value="10.22.3.30,10.22.3.31,10.22.3.32,10.22.3.33"/> > </bean> > </property> > </bean> > </property> > </bean> > </property> > > </bean> > </beans> > > Now instead of "10.22.3.30,10.22.3.31,10.22.3.32,10.22.3.33", I would like > to give a different set of IPs to the fail-over cluser, for example, > "10.22.4.30,10.22.4.31,10.22.4.32,10.22.4.33". > > Is it possible to just specify a variable in the configuration file, such > as: > > <bean class="org.springframework.util.StringUtils" > factory-method="commaDelimitedListToSet"> > <constructor-arg type="java.lang.String" value="${nodeIpAddresses}"/> > </bean> > > And then pass the specific IP addresses to the configuration when we > starting Ignite?
