Subject Re: ignite cache process entry should inject source?
Date Fri, 22 Jan 2016 07:22:26 GMT
Hi Wei Jiang,

You can inject @SpringResource and @SpringApplicationContextResource 
into Ignite Service or Ignite Compute. This feature is not supported for 
individual cache entries, at least because of performance reasons.
@Autowired is unsupported for both Ignite services and computes.

So if you need to process the entries inside of Ignite Compute or Ignite 
Service then just inject a resource there using one of the annotations 

The main point here is that all the nodes have to be started as a part 
of spring app context or have to have a reference to it.
Please refer to org.apache.ignite.IgniteSpring for more info.
