Denis Koblov updated IGNITE-6586:
---------------------------------
Description:
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="gridLogger">

</property>
<property name="userAttributes">

<property name="compactFooter" value="false"/>
</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.
