public class IgniteSpringBean extends Object implements Ignite, org.springframework.beans.factory.DisposableBean, org.springframework.beans.factory.SmartInitializingSingleton, org.springframework.context.ApplicationContextAware, Externalizable
Ignition methods.
In other words, this bean class allows to inject new grid instance from
Spring configuration file directly without invoking static
Ignition methods. This class can be wired directly from
Spring and can be referenced from within other Spring beans.
By virtue of implementing DisposableBean and SmartInitializingSingleton
interfaces, IgniteSpringBean automatically starts and stops underlying
grid instance.
A note should be taken that Ignite instance is started after all other
Spring beans have been initialized and right before Spring context is refreshed.
That implies that it's not valid to reference IgniteSpringBean from
any kind of Spring bean init methods like PostConstruct.
If it's required to reference IgniteSpringBean for other bean
initialization purposes, it should be done from a ContextRefreshedEvent
listener method declared in that bean.
<bean id="mySpringBean" class="org.apache.ignite.IgniteSpringBean">
<property name="configuration">
<bean id="grid.cfg" class="org.apache.ignite.configuration.IgniteConfiguration">
<property name="igniteInstanceName" value="mySpringGrid"/>
</bean>
</property>
</bean>
Or use default configuration:
<bean id="mySpringBean" class="org.apache.ignite.IgniteSpringBean"/>
AbstractApplicationContext ctx = new FileSystemXmlApplicationContext("/path/to/spring/file");
// Register Spring hook to destroy bean automatically.
ctx.registerShutdownHook();
Ignite ignite = (Ignite)ctx.getBean("mySpringBean");

public IgniteConfiguration configuration()
configuration in interface Ignitepublic IgniteConfiguration getConfiguration()
This method is required for proper Spring integration and is the same as
configuration().
See https://issues.apache.org/jira/browse/IGNITE-1102 for details.
NOTE:
SPIs obtains through this method should never be used directly. SPIs provide
internal view on the subsystem and is used internally by Ignite kernal. In rare use cases when
access to a specific implementation of this SPI is required - an instance of this SPI can be obtained
via this method to check its configuration properties or call other non-SPI
methods.
