> Hello.
> I use a spring-ignite in my application. When using ServiceGrid I noticed a
> feature.
> I created the following class for the ServiceGrid:
> {code:java}
> public class SimpleService implements Service, ApplicationContextAware {
> private ApplicationContext applicationContext;
> @Override
> public void setApplicationContext(ApplicationContext applicationContext)
> throws BeansException {
> this.applicationContext = applicationContext;
> }
> @Override
> public void init(ServiceContext serviceContext) throws Exception {
> if (applicationContext == null) {
> System.out.println("ApplicationContext is null");
> }
> }
> @Override
> public void execute(ServiceContext serviceContext) throws Exception {
> }
> @Override
> public void cancel(ServiceContext serviceContext) {
> }
> }
> {code}
> {code:java}
> <bean id="igniteSpringBean" class="org.apache.ignite.IgniteSpringBean">
> <property name="configuration">
> <bean class="org.apache.ignite.configuration.IgniteConfiguration">
> <!-- Enabling the peer-class loading feature. -->
> <property name="peerClassLoadingEnabled" value="false"/>
> <property name="gridLogger">
> <bean class="org.apache.ignite.logger.slf4j.Slf4jLogger"/>
> </property>
> <property name="userAttributes">
> <map key-type="java.lang.String"
> value-type="java.lang.Object">
> <entry key="simpleservice" value="true"
> value-type="java.lang.Boolean"/>
> </map>
> </property>
> <property name="serviceConfiguration">
> <list>
> <bean
> class="org.apache.ignite.services.ServiceConfiguration">
> <!-- Unique service name -->
> <property name="name" value="SimpleService"/>
> <!-- Service implementation's class -->
> <property name="service" >

> </bean>
> </property>
> </bean>
> </property>
> {code}
> After start the application i see following text on the output console:
> *ApplicationContext is null*
> I see 4 instances on the Memory viewer:
> !https://i.imgur.com/OU7CT8D.png!
> This is because the ignite serialize spring bean, than deserialize it and
> used new instance as an instance of the service. Why? Why instance of the
> service not equals instance in the spring application contex? And is it
> possible to change this case?
> Thanks.
