about AOP development
Hi：
In a distributed environment, if use the spring AOP programming,
generated a class of byte code enhancement, then the error will be
reported as follows:
java.lang.ClassNotFoundException:
demo.computegrid.ComputeGridService$$EnhancerBySpringCGLIB$$7b44b192
This error I understand, this class does not exist on the remote node.
But the question is, is it a technical limitation of Ignite, or is it
the way I use it，or is it a bug?
I opened the peer class loading , the normal deployment I did not test,
but I estimate it will be the same error.
Re: about AOP development
Posted by Dmitriy Setrakyan <ds...@apache.org>.
This module enables grid-enabling standard Java methods using @Gridify
annotation in conjunction with some AOP framework. However, AOP is no
longer a popular technology, and we thought that having documentation at
Javadoc level should suffice.

Hi：
I found the ignite-aop module on github, and I asked what the module is
to do?
In addition, this module does not have a document.

Hi：
I am at home now, can not reproduce.
Do not need to cluster, to get the code to run directly, you can reproduce.
If you use the AOP spring technology, through the following code:
ClusterGroup cg = ignite.cluster().forServers();
IgniteCompute compute = ignite.compute(cg);
IgniteServices svcs = ignite.services(cg);
Service service = (Service)ac.getBean("computeGridService");
svcs.deployNodeSingleton("computeGridService", service);
Will throw an nullexception.

Hi:
I understand your approach, it should be feasible, but not very elegant.
If use ProxyFactory in spring. At runtime dynamically add interceptor,
can solve the problem, but performance will influence.
I switched to a different way of writing, using the Service mechanism,
code has been updated to GitHub, throws NullException. I survey the
reason, the problem is in service deployment process of marshal and
unmarshal stage, because of AdvisedSupport's methodCache is transient,
this may be a compatibility problem, also asks you to look at.

As for the last step, let me correct myself:
3. Start server Ignite node from spring context *AND *put spring jars
inside classpath in *.sh file. Be sure, that both nodes are using the same
xml context.

Re: Re: about AOP development

Hi!
I've checked your code and spot an issue. The root cause, is using of
Autowired annotation, since it cause bean to be serialized on a client
side, and that leads ClassNotFoundException on the server side during bean
deserialization, since server was started from *.sh, without necessary
spring jars in the classpath.
Good news here, that it could be fixed easily with those steps:
1. Remove Autowired from transferred entities as ComputeGridJob
2. When you need an applicationContext, use
@SpringApplicationContextResource annotation. You are need to use it in
your ComputeGridTask.
3. Start server Ignite node from spring context, or put spring jars
inside classpath in *.sh file.
Also, you can simplify your solution for ComputeGridService by using
@ServiceResource. Take a look:
https://apacheignite.readme.io/docs/service-example
Thanks!

Hi：
I have already opened the peerClassLoading.
My practice is in eclipse create a java project, developed a
ComputeTaskSplitAdapter examples, then in the ComputeJobAdapter call
configured spring interceptors service. This example in eclipse
operation is no problem.
But if I open a node in the command line by ignite.sh, it will prompt
the following error in the command line.
In the default configuration file of ignite, the same configuration of
the peerClassLoading=true.

Yakov:
I have already opened the peerClassLoading.
Attachment is a complete eclipse project that can be run.
The required jar package is as follows:
aopalliance.jar
cache-api-1.0.0.jar
commons-logging-1.2.jar
ignite-core-1.5.0.final.jar
spring-aop-4.1.9.RELEASE.jar
spring-beans-4.1.9.RELEASE.jar
spring-context-4.1.9.RELEASE.jar
spring-core-4.1.9.RELEASE.jar
spring-expression-4.1.9.RELEASE.jar
The problem is that there is no problem with a single node, if the
ignite.sh is started on the command line, the following error will occur.
